The Final Entrant – Last Nuclear Utility in Japan Applies for Restart

Yesterday, the saga of nuclear energy in post-Fukushima Japan reached an important milestone as the final utility that owns nuclear power plants in that country applied to the regulator for restart, in an event that snuck under the radar of most news venues.

Hokuriku Electric Power Company yesterday submitted its application to have Shika Nuclear Power Plant Unit 2 examined by the Nuclear Regulation Authority under the revised guidelines for nuclear plant safety. Hokuriku owns only one nuclear power station, Shika, which has two units; Unit 1 is a BWR-5, while Unit 2 is an ABWR that went into commercial operation in March 2006. This application for Unit 2 means a number of things; it marks the end of the final holdout, if you will, by a nuclear utility; it shows that all utilities with nuclear plants will attempt to restart at least one unit; and it answers the question once and for all whether the Japanese utilities unanimously want to continue to include nuclear in their fuel mixes for the future.

Hokuriku has stated that work at the site (which mirrors heavy site work underway at most nuclear plants in post-Fukushima Japan) is not yet complete and that it does not have a specific restart date for this nuclear plant.

Shika Unit 2 had some press before this; this plant, along with Chubu Electric Power Company’s Hamaoka Unit 5, made some notoriety in 2006 when both were shut down for some time due to turbine generator problems. Hamaoka-5 shut down first in June 2006, actually on a turbine trip due to high vibration; this was quickly discovered to be a result of broken blades in the “B” or center (of three) of the low pressure turbines on its Hitachi TC6F-52 turbine generator. Because Shika Unit 2 had the same model turbine generator, it was ordered shut down in July 2006 for inspection; this revealed similar, if not as extensive, damage.

Hitachi paid for repairs to the Hamaoka and Shika turbine generators; the Hamaoka unit was back on-line in February 2007, eight months after the event. Shika Unit 2 however was saddled with a reduced power rating, and was also delayed in its restart while NISA (the former nuclear regulator) dealt with systemic problems at the site. Shika Unit 2 finally restarted in June 2008, rated at 1108 MWe instead of its original designed 1358 MWe. Hokuriku detailed plans to modify the turbine in 2010 and return the plant to its original full rating, but the only increase allowed was to 1206 MWe, which is where the official plant rating lies at the moment according to Nuclear Regulation Authority records. Hitachi has since modified its designs to eliminate the problems that originally caused these failures, which have not recurred in any other Hitachi turbine generators.

The restart applications, as they came

It is now appropriate to briefly detail the nuclear plant restart applications in a neat bunch as we find ourselves at a convenient historical point from which to look back.

The initial applications for restart actually came in a rush; on July 8, 2013, four utilities applied for restart examination for no fewer than 10 reactors at five sites. Quite interestingly, all of these were Mitsubishi pressurized water reactors); their ages varied, with commercial operation starting dates ranging from 1984 to 2009, in two, three, and four loop configurations. These were Hokkaido Electric Power’s Tomari NPP Units 1, 2 and 3; Kansai Electric Power’s Ohi NPP Units 3 and 4 and Takahama NPP Units 3 and 4; Shikoku Electric Power’s Ikata Unit 3; and Kyushu Electric Power’s Sendai Units 1 and 2.

Just four days later on July 12, 2013, Kyushu Electric Power also applied for its Genkai NPP Units 3 and 4. These are also Mitsubishi PWR plants.

As had long been expected, on September 27, 2013, Tokyo Electric Power applied to restart two units at its massive Kashiwazaki-Kariwa NPP—and these, Units 6 and 7, were the first boiling water reactors of any kind to apply to restart. These units are Hitachi-GE-Toshiba ABWRs, and are the newest TEPCO nuclear units.

Chugoku Electric Power applied to restart Shimane NPP Unit 2, a Hitachi BWR-5, on December 25, 2013. Two days later on December 27th, Tohoku Electric Power applied to restart Onagawa NPP Unit 2—another BWR-5, but of Toshiba heritage.

The first application of 2014 was February 14, when Chubu Electric Power applied to restart Hamaoka Unit 4, a Toshiba-Hitachi BWR-5.

Japan Atomic Power Company (JAPC) applied to restart its Tokai Daini NPP, a GE BWR-5, on May 20, 2014. With a commercial operation date in November 1978, this is by far the oldest reactor applied for restart in Japan; the next closest date is Sendai Unit 1, commercially operational in 1984.

It was June before another application was made; on the 10th, Tohoku Electric Power applied to restart Higashidori 1, a BWR-5 of rather recent vintage, having entered commercial service in 2005.

And, of course, as we now know Shika Unit 2 applied yesterday (August 12, 2014,) marking only the third ABWR to apply for restart.

In total, the restart applications include 12 Mitsubishi PWRs, three ABWRs, and a total of five BWR-5 reactors of various heritage, making 20 reactors overall.

Kashiwazaki-Kariwa (TEPCO, two units applied), Tomari (Hokkaido, three units), Shika (Hokuriku, one unit applied), Shimane (Chugoku, one unit applied), Ikata (Shikoku, one unit applied), Takahama and Oi (both Kansai, four units total), and Genkai and Sendai (both Kyushu, four units applied) are on the West coast of Japan or on coasts facing west, making a total of 16 of the 20 units that are not subjected to future tsunami from the same fault that triggered the Great East Japan/Tohoku Earthquake and Tsunami. The majority of these 16 units (12) are the Mitsubishi PWR units; three more of these 16 units are the ABWRs applied for restart.

The results of these restart applications are, of course, expected to be an exceedingly mixed bag. Anti-nuclear court rulings, mistrust among prefectural governments, environmental groups, and anti-nuclear activists are already having a major impact on the processes to restart the nuclear plants. It is certain that we will look back on this historical point as a mere footnote; the hard work of both preparing the plants for future events and regaining the public trust all lies mainly ahead, and it is likely to take many years to bottle those results as conveniently as we bottle the applications here.

Japan Nuclear Restarts: Abe Says “Will See To It,” Courts Differ, Plants Prepare

By Will Davis

HamaokaChubuElectric“I will see to it by some means or other. I will properly deal with it.” So go the reported words of Japanese Prime Minister Shinzo Abe regarding the restart of nuclear power plants in Japan, as printed recently in the Japanese press. At the present time, while the Japanese government and courts seem to be at odds on restarting plants—with the public left in the middle—those at the nuclear plants themselves must count on eventual approval to restart and must ensure required measures are completed properly. Those preparing for restart continue to work toward that end while facing an improving, but not yet by any means certain, situation in the public and legal arenas.

Abe says yes, court says no

Those wishing for nuclear plant restarts in Japan, and especially power companies and large manufacturers (which consider their businesses in great peril), were bolstered by the continued support for nuclear restarts expressed by Abe, although it’s now becoming clear that a one-man fight isn’t what lies ahead. Abe’s recent statement, specifically about Sendai Nuclear Power Plant (NPP), comes on the heels of a public presentation to the Prime Minister of produce from the governor of Fukushima Prefecture—a sure sign that life indeed continues in the prefecture. That rosy picture of recovery stands opposed by courts, however.

Just last May, the Fukui Court issued an order to Kansai Electric barring the restart of reactors at the Oi NPP. The language of the order has more recently been translated into English, and the finding is troubling—the court basically saying that no person or establishment is capable of predicting the maximum severity and effect of prospective natural disasters; and that since the people of Japan generally derive their welfare and well-being from the land, it can be ruled illegal to operate nuclear plants that could in theory lead to the loss of the land and well-being of the people.

Residents in the immediate vicinity of Sendai NPP in Kagoshima Prefecture were this week issued iodine pills as part of a disaster preparedness plan, along with access to pharmacists who could answer questions, according to NHK World. One resident interviewed said that he indeed felt better because of this “ounce of prevention” approach. In some regions, public opinion appears to sway toward the return of nuclear energy, as utilities and prefectural governments make advance preparations and keep the public “in the loop.”

Preparing by building and training

KashiwazakiKariwaAs scenes of quite public debate continue, the utilities meanwhile have long recognized the need to restart their nuclear plants, if at all possible, to begin to recoup some of the massive losses they’re incurring—as a result of having to buy large amounts of fossil fuel and having to build temporary fossil-fired power plants to make up for the loss of generation from nuclear plants. And lest there be any doubt, overall power generation is still far, far short of what it had been with all nuclear plants available.

Some plants have experienced setbacks. This week, Shikoku Electric Power Company announed that its Ikata NPP would delay restarting by up to a year because its on-site emergency control center didn’t meet required revised seismic standards.

Others continue apace. We’ve reported here on the massive amount of time and money that Tokyo Electric Power Company (owner of Fukushima Daiichi) has put into its Kashiwazaki–Kariwa nuclear plant on the opposite coast of Japan; these safety measures continue with further massive construction. A recently published video displays the continued wide effort underway to meet all the required precautions and standards, and is worth viewing in its entirety for anyone interested in the preparations at nuclear plants in Japan:

Click here to watch the TEPCO Kashiwazaki-Kariwa video

Japan’s Nuclear Regulation Authority (NRA) released a report stating that the triggering event for the Fukushima Daiichi nuclear accident was in fact the tsunami, and not the earthquake itself, lending support to safety actions taken at Kashiwazaki–Kariwa and other nuclear plant sites around Japan (including Chubu Electric’s Hamaoka NPP and Kyushu Electric Power’s Genkai and Sendai NPP’s) in the sense that the majority of expenditure lies in prevention of damaging effects from tsunami. A previous Japanese government panel had implicated the quake as the cause, but the NRA’s investigation has resulted in little or no evidence that the quake itself caused any damage to the plants that would have led to core melt. For example, the summary of the NRA report states that any small leaks caused by the quake would not have caused a threat to core integrity within 10 hours, and that there were no detectable signs of any serious breach of primary plant integrity during the time between the quake and the arrival of the tsunami.

It seems assured now—given the work required, the recent court position, and the overall sensitivity of the issue—that none of the nuclear plants in Japan will restart before autumn. As that original hope slips, the public and industry continue to forge a new understanding of the importance of safety in the Japanese nuclear power industry.

Columbia Generating Station Sets New Generation Record

By Laura Scheele

Ratepayers in the Pacific Northwest have reason to celebrate the dedicated employees of Energy Northwest’s 1170-megawatt Columbia Generating Station:  The Northwest’s sole nuclear energy facility generated a record 9.7 million megawatt hours of electricity during the fiscal year that ended Monday, June 30—eclipsing a previous record of 9.5 million megawatt hours in fiscal year 2006.

This generation mark has been set with safety and efficiency, as well as adherence to the core principles of the organization’s Excellence Model. The Columbia Generating Station has operated more than 4.5 years without an unplanned shutdown, and Energy Northwest has surpassed 14 million work-hours without lost time due to injury.

“This performance is a testament to the organization’s alignment to the Excellence Model and commitment to fixing plant equipment and demonstrating the right behaviors,” said Brad Sawatzke, vice president of nuclear generation, in a message to employees. “Most importantly, the team reached this milestone while performing safely in the areas of nuclear, radiological, industrial and environmental safety.”

In a broader context, the 100 commercial nuclear energy reactors operating in the United States have continued to maintain their overall share of U.S. electricity generation through great improvements in efficiency and performance over recent decades, as well as massive additional capacity added through power uprates—for more on uprates in detail see Nuclear power uprates: what, how, when, and will there be more? at ANS Nuclear Cafe.

Nuclear professionals: Establish standing now to improve operational radiation limits

By Rod Adams

On August 3, 2014, the window will close on a rare opportunity to use the political process to strongly support the use of science to establish radiation protection regulations. Though it is not terribly difficult for existing light water reactors and fuel cycle facilities to meet the existing limits from 40 CFR 190 regarding doses to the general public and annual release rate limits for specific isotopes, there is no scientific basis for the current limits. If they are maintained, it would hinder the deployment of many potentially valuable technologies that could help humanity achieve a growing level of prosperity while achieving substantial reductions in air pollution and persistent greenhouse gases like CO2.

In January 2014, the U.S. Environmental Protection Agency issued an Advanced Notice of Proposed Rulemaking (ANPR) to solicit comments from the general public and affected stakeholders about 40 CFR 190, Environmental Radiation Protection Standards for Nuclear Power Operations.

The ANPR page has links to summary webinars provided to the public during the spring of 2014, including presentation slides, presentation audio, and questions and answers. This is an important opportunity for members of the public, nuclear energy professionals, nuclear technical societies, and companies involved in various aspects of the nuclear fuel cycle to provide comments about the current regulations and recommendations for improvements. Providing comments now, in the information-gathering phase of a potential rulemaking process, is a critical component of establishing standing to continue participating in the process.

us epa logo no text 214x201It also avoids a situation where an onerous rule could be issued and enforced under the regulator’s principle that “we provided an opportunity for comment, but no one complained then.”

The existing version of 40 CFR 190—issued on January 13, 1977, during the last week of the Gerald Ford administration—established a limit of 0.25 mSv/year whole body dose and 0.75 mSv/year to the thyroid for any member of the general public from radiation coming from any part of the nuclear fuel cycle, with the exception of uranium mining and long-term waste disposal. Those two activities are covered under different regulations. Naturally occurring radioactive material is not covered by 40 CFR 190, nor are exposures from medical procedures.

40 CFR 190 also specifies annual emissions limits for the entire fuel cycle for three specific radionuclides for each gigawatt-year of nuclear generated electricity: krypton-85 (50,000 curies), iodine-129 (5 millicuries), and Pu-239 and other alpha emitters with longer than one year half-life (0.5 millicuries).

It is important to clarify the way that the U.S. federal government assigns responsibilities for radiation protection standards. The Nuclear Regulatory Commission has the responsibility for regulating individual facilities and for establishing radiation protection standards for workers, but the EPA has a role and an office of radiation protection as well.

The Atomic Energy Act of 1954 initially assigned all regulation relating to nuclear energy and radiation to the Atomic Energy Commission (AEC). However, as part of the President’s Reorganization Plan No. 3 of October 1970, President Nixon transferred responsibility for establishing generally applicable environmental radiation protection standards from the AEC to the newly formed EPA:

…to the extent that such functions of the Commission consist of establishing generally applicable environmental standards for the protection of the general environment from radioactive material. As used herein, standards mean limits on radiation exposures or levels or concentrations or quantities of radioactive material, in the general environment outside the boundaries of locations under the control of persons possessing or using radioactive material.

(Final Environmental Impact Statement, Environmental Radiation Protection Requirements for Normal Operations of Activities in the Uranium Fuel Cycle, p. 18.)

Before the transfer of environmental radiation responsibilities from the AEC to the EPA, and until the EPA issued the new rule in 1977, the annual radiation dose limit for a member of the general public from nuclear fuel cycle operations was 5 mSv—20 times higher than the EPA’s limit.

The AEC had conservatively assigned a limit of 1/10th of the 50 mSv/year applied to occupational radiation workers, which it had, in turn, conservatively chosen to provide a high level of worker protection from the potential negative health effects of atomic radiation.

The AEC’s occupational limit of 50 mSv was less than 1/10th of the previously applied “tolerance dose” of 2 mSv/day, which worked out to an annual limit of approximately 700 mSv/year. That daily limit recognized the observed effect that damage resulting from radiation doses was routinely repaired by normal physiological healing mechanisms.

Aside: After more than 100 years of human experience working with radiation and radioactive materials, there is still no data that prove negative health effects for people whose exposures have been maintained within the above tolerance dose, initially established for radiology workers in 1934. End Aside.

From the 1934 tolerance dose to the EPA limit specified in 1977 (and still in effect), requirements were tightened by a factor of 2800. The claimed basis for that large conservatism was a lack of data at low doses, leading to uncertainty about radiation health effects on humans. Based on reports from the National Academy of Sciences subcommittee on the Biological Effect of Ionizing Radiation (BEIR), the EPA rule writers simply assumed that every dose of radiation was hazardous to human health.

The EPA used that assumption to justify setting limits that were quite low, but could be met by the existing technology if it was maintained in a like-new condition for its entire operating life. Since the rule writers assumed that they were establishing a standard that would protect the public from an actual harm, they did not worry about the amount of effort that would be expended in surveys and monitoring to prove compliance. As gleaned from the public webinar questions and answers, EPA representatives do not even ask about compliance costs, because they are only given the responsibility of establishing the general rule; the NRC is responsible for inspections and monitoring enforcement of the standard.

The primary measured human health effects used by the BEIR committee in formulating their regulatory recommendations were determined based on epidemiological studies of atomic bomb survivors. That unique population was exposed to almost instantaneous doses greater than 100 mSv. Based on their interpretation of data from the Life Span Study of atomic bomb victims, which supported a linear relationship between dose and effect in the dose regions available, the BEIR committee recommended a conservative assumption that the linear relationship continued all the way down to a zero dose, zero effect origin.

For the radionuclide emissions limits, the EPA chose numbers that stretch the linear no-threshold dose assumption by applying it to extremely small doses spread to a very large population.

The Kr-85 standard is illustrative of this stretching. It took several hours of digging through the 240-page final environmental impact statement and the nearly 400-page collection of comments and responses to determine exactly what dose the EPA was seeking to limit decades ago, and how much it thought the industry should spend to achieve that protection.

The EPA determined that allowing the industry to continue its then-established practice of venting Kr-85 and allowing that inert gas to disperse posed an unacceptable risk to the world’s population.

It calculated that if no effort was made to contain Kr-85, and the U.S. industry grew to a projected 1000 GW of electricity production by 2000, an industry with full recycling would release enough radioactive Kr-85 gas to cause about 100 cases of cancer each year.

The EPA’s calculation was based on a world population of 5 billion people exposed to an average of 0.0004 mSv/year per individual.

At the time that this analysis was performed, the Barnwell nuclear fuel reprocessing facility was under construction and nearly complete. It had not been designed to contain Kr-85. The facility owners provided an estimate to the EPA that retrofitting a cryogenic capture and storage capability for Kr-85 would cost $44.6 million.

The EPA finessed this exceedingly large cost for tiny assumed benefit by saying that the estimated cost for the Barnwell facility was not representative of what it would cost other facilities that were designed to optimize the cost of Kr-85 capture. It based that assertion on the fact that Exxon Nuclear Fuels was in a conceptual design phase for a reprocessing facility and had determined that it might be able to include Kr-85 capture for less than half of the Barnwell estimate.

GE, the company that built the Midwest Fuel Recovery Plant in Morris, Illinois, provided several comments to the EPA, including one about the low cost-benefit ratio of attempting to impose controls on Kr-85:

Comment: The model used to determine the total population dose should have a cutoff point (generally considered to be less than 0.01 mSv/year) below which the radiation dose to individuals is small enough to be ignored.

In particular, holdup of krypton-85 is not justified since the average total body dose rate by the year 2000 is expected to be only 0.0004 mSv/year.

Response: Radiation doses caused by man’s activities are additive to the natural radiation background of about 0.8-1.0 mSv/year [note: the generally accepted range of background radiation in the mid 1970s, as indicated by other parts of the documents was 0.6 - 3.0 mSv/yr] whole-body dose to which everyone is exposed. It is extremely unlikely that there is an abrupt discontinuity in the dose-effect relationship, whatever its shape or slope. at the dose level represented by the natural background that would be required to justify a conclusion that some small additional radiation dose caused by man’s activities can be considered harmless and may be reasonably ignored.

For this reason, it is appropriate to sum small doses delivered to large population groups to determine the integrated population dose. The integrated population dose may then be used to calculate potential health effects to assist in making judgements on the risk resulting from radioactive effluent releases from uranium fuel cycle facilities, and the reasonableness of costs that would be incurred to mitigate this risk.

Existing Kr-85 rules are thus based on collective doses, and a calculation of risks, that is now specifically discouraged by both national (NCRP) and international (ICRP) radiation protection bodies. It is also based on the assumption of a full-recycle fuel system and 10 times as much nuclear power generating capacity as exists in the United States today.

Since the level specified is applied to the entire nuclear fuel cycle industry in the United States, the 40 CFR 190 ANPR asks the public to comment about the implications of attempting to apply limits to individual facilities. This portion of the discussion is important for molten salt reactor technology that does not include fuel cladding to seal fission product gases, and for fuel cycles that envision on-site recycling using a technology like pyroprocessing instead of transporting used fuel to a centralized facility for recycling.

There are many more facets of the existing rule that are worthy of comment, but one more worth particular attention is the concluding paragraph from the underlying policy for radiation protection, which is found on the last page of the final environmental impact statement:

The linear hypothesis by itself precludes the development of acceptable levels of risk based solely on health considerations. Therefore, in establishing radiation protection positions, the Agency will weigh not only the health impact, but also social, economic, and other considerations associated with the activities addressed.

In 1977, there was no consideration given to the fact that any power that was not generated using a uranium or thorium fuel cycle had a good chance of being generated by a power source producing a much higher level of carbon dioxide. In fact, the EPA in 1977 had not even begun to consider that CO2 was a problem. That “other consideration” must now play a role in any future decision-making about radiation limits or emission limits for radioactive noble gases.

If EPA bureaucrats are constrained to use the recommendations of a duly constituted body of scientists as the basis for writing its regulations, the least they could do before rewriting the rules is to ask the scientific community to determine if the linear no-threshold (LNT) dose response model is still valid. The last BEIR committee report is now close to 10 years old. The studies on which it was based were conducted during an era in which it was nearly impossible to conduct detailed studies of DNA, but that limitation has now been overcome by advances in biotechnology. There is also a well-developed community of specialists in dose response studies that have produced a growing body of evidence supporting the conclusion that the LNT is not “conservative”—it is simply incorrect.

Note: Dose rates from the original documents have been converted into SI units.

Nuclear Energy in Japan Steps into the Chasm

by Will Davis

Recent developments in Japan concerning the Fukushima Daiichi plant recovery specifically, and nuclear energy generally, have not been exceedingly positive. The difficult recovery efforts at the crippled nuclear plant are not all proceeding smoothly; delays and technical problems continue to abound and confound. Meanwhile, on a broader scale, the national pullback from nuclear may be even more serious and have longer term effects than anyone realizes.

Fukushima Daiichi—Where is the ice wall?

Tokyo Electric Power Company (TEPCO) reported that efforts to block the flow of water through below-grade piping conduits have failed, largely because the currents in these conduits are fast enough that the water cannot freeze. Sealing these “trenches”—a separate issue from the “ice wall” discussed below—is a major part of the contaminated water mitigation process; it is what will, ultimately, prevent contaminated water that is inside the nuclear plant buildings (reactor buildings and turbine buildings) from getting out into the general grounds near the plants. At this writing, no solution has been devised, although TEPCO hopes to better control the currents and/or add more coolant pipes if needed.

Similarly, TEPCO also repeatedly delayed the expected completion date for the “frozen earth” ice wall that will surround Units 1 through 4 underground, which will prevent groundwater from intruding into the buildings. Japan’s Nuclear Regulation Authority (NRA) has publicly expressed concern over the delay in this process, urging TEPCO to attack the problem with utmost vigor. According to reporting from NHK (Japan’s national public broadcasting organization), the NRA has urged TEPCO to come up with definite steps by the end of July to ensure a timely completion of the ice wall.

TEPCO continues to have the “to be expected” occasional system problem here and there, but since the general public’s attitude toward TEPCO is definitely not one of trust and understanding, all events make for wide and negative press. Early this week, TEPCO temporarily lost cooling to the spent fuel pool at Unit 5 on the Fukushima Daiichi site. To make matters worse in the public eye, original statements made to NHK/NHK World (which have now been removed from their sites) indicated that TEPCO had no clue when cooling could be restored, and that the pool would hit its operating temperature limit in a few weeks.

The truth of the matter is that the very next day, the residual heat removal system was placed in service to restore spent fuel pool cooling. But the shaky initial message had already gone out, with a seemingly powerless undertone that certainly didn’t underscore the ability of those at site to deal with the situations they encounter (TEPCO has since released a detailed account of this incident).

On the positive side, as of this writing 1188 out of the 1533 fuel elements in the spent fuel pool at Unit 4 have been transferred to the site’s common fuel pool. Future operations will see some of this fuel also transferred to the Unit 5 spent fuel pool.

Restarting plants might be slow

In a completely separate development, a Fukui court has blocked the restart of two units at Kansai Electric Power Company’s Ohi Nuclear Power Plant, citing in part that the plant had operated from July 2012 to September 2013 without incorporating new or revised safety standards. What relevance this has to the restarting of a plant now completely meeting the revised NRA standards is unclear, but the precedent is set: Courts are ready and willing to act to counter the Japanese government’s mission to restore the Japanese economy by restarting nuclear plants.

Eventually, it does seem certain that many of the nuclear plants in Japan will restart, as the need becomes increasingly critical to improve Japan’s import-export ratio and drive down the cost of energy. The Japanese government, the utilities, and most major corporations (and their lobbying groups) have expressed the desire to restart the plants; at the same time, however, local and highly vocal groups are speaking out and taking legal action.

Separately, Japan’s NRA has publicly made some severe comments after finding a number of inadequacies in early applications to restart plants submitted by a number of owner-operators. According to the NRA, further requests for information and clarification will be necessary—driving the potential restart dates for even the earliest expected plant restart (Sendai) beyond the high demand period of the summer heat. Sendai is still expected to be the first to restart, though—perhaps as soon as the autumn months.

The “chasm”

At the tip of Aomori Prefecture lies the site of what is now the only nuclear power plant actively under construction in Japan—the Ohma Nuclear Plant, owned by Electric Power Development Company, Ltd., commonly known as “J-Power.”

That’s right—this is the only nuclear plant in Japan actively under construction. After the earthquake and tsunami in 2011, all nuclear plant construction was effectively halted in Japan. Of the three that were under construction, two were deferred indefinitely; of the 12 announced or proposed, all were deferred indefinitely or cancelled.

The plant near Ohma—an Hitachi advanced boiling water reactor—has been “on the drawing boards” for many years and was several times deferred. First planned in the early 1980s (the site survey was accomplished in 1983), the plant’s site preparation didn’t begin until 2008, with actual plant construction beginning in 2010, but suspended from the time of the 2011 quake until October 2012 when it was resumed. As might have been expected, anti-nuclear opponents have taken the Fukui court finding as a precedent and have now acted to block completion of the Ohma nuclear plant as well. It appears an extended court battle may now be in the offing.

This portends a “nuclear chasm,” similar to what we now face in the United States. The cessation of new nuclear plant orders in the U.S. in 1978, coupled with a flood of nuclear plant cancellations that followed, means there will come a time when nuclear plants in the United States are shutting down and decommissioning—even including life extensions—faster than new nuclear plants come on-line.  The nuclear industry has long known this would occur; but it is being accelerated in some quarters by economic conditions (e.g., Kewaunee) or unanticipated material conditions (e.g., Crystal River, San Onofre-2 and -3.)

The result in the case of Japan will be that there too will come a time when, assuming that many plants restart, there will be no new plants in the wings to take the place of the older plants when they shut down. The present social environment in Japan now approaches the atmosphere in the United States during the 1970s and ’80s, with continuous anti-nuclear “environmentalist” opposition that can kill a nuclear energy project. This does not bode well for a nation that imports more than two-thirds of its energy needs; it requires a careful and sober analysis of the nation’s energy needs—and the place that nuclear power plays in those needs—now before the chasm cannot be escaped. Japan, unlike the United States, cannot fall back on indigenous coal or gas—it has neither.

The actions of the Japanese utilities lately have done little to steer away from the road to the chasm; harsh words from the NRA about inadequacies in the initial round of restart applications bears witness to this. Public trust is key, and if it is perceived that utilities wish to simply “slide by and play along” until they get their nuclear plants back—they won’t get them back.

Time will tell what plays out for Japan’s nuclear energy enterprise, but at the moment a great deal of work needs to be done to swing the course away from an abyss.

Nuclear Power Uprates: What, how, when, and will there be more?

Calvert Cliffs Plant; two unit nuclear generating station. Baltimore Gas and Electric Company brochure, October 1980.

By Will Davis

I received an email this morning (in the midst of my daily avalanche of promotional emails) with a link to a brief story about uprating of nuclear plants worldwide (in other words, increasing the power output of an already-built plant)—what had been done, how many were planned, and so forth. I wondered to myself just how many nuclear plants in the United States had been uprated, and when they started—and given the recent hullabaloo over the recent U.S. Environmental Protection Agency CO2 emission policy, it seems like (in addition to discussing small modular reactors) we might also want to toss the uprate card back on the table. Instead of flat or only slightly rising demand for electricity, we may face a steady lowering of generating capacity as plants that are high CO2 emitters (and thus violators) get shut down. Sure, renewables will play a part, and so will increased efficiency, but having more power is better than having less, or too little. I found no quick and easy reference for the kind of analysis I wanted, so I took a little time and did it myself.

Uprate? You can do that? How?

Power Meters NS Savannah 2Yes, uprates can be done—and it’s been happening for a long time. In nuclear power we talk about three kinds of uprates, or increases in power outputs, for the power plants. Very briefly, these are as follows, in increasing order of the amount of power gained:

  • MUR or “Measurement Uncertainty Recapture”: Think about this as saying that we’re going to put more accurate instruments into a plant, and thus will be able to develop a very slightly (maybe 1 percent or so) higher power now that we’re more certain of the exact parameters. Originally, it turns out, the instruments built for nuclear plants years back were quite accurate—so that these types of uprates are typically small. For all you “car nuts” out there, think “police speedometer.” (Do they even sell “police package” cars any more? My father had a Caprice LTZ… but I digress.)
  • “Stretch”: This uprate uses the installed equipment to a higher degree of its maximum capability. These are a few to several percent power increases.
  • “Extended Power Uprate”: This is the “biggie.” This is a major job, including replacement and upgrading of the turbine generator, perhaps other plant systems too such as pumps; it’s a major investment and involves a lot of complicated and heavy work. The payoff, though, is that the return on the investment is earlier, and thus the profit comes earlier, than building any kind of new power plant.

Now, the nuclear industry has for some years, in a dearth of construction of new plants, been pointing out that, “Yes, while we’re not building new plants, we’ve had lots and lots of uprates of existing plants—so that we’ve added capacity equal to a number of completely new nuclear plants.”

That’s exactly correct. Over the years since uprates began (in the present sense—more on that later) U.S. nuclear plants have added 6908 MWe of generating capacity (a figure I got by adding up NEI’s graphical figures found here.) If we think about that in terms of the nuclear plants being built brand new today, which are nominally 1000-MWe plants, that’s almost seven new nuclear plants’ worth of power—but at a fraction of the overall cost, because no new siting or major construction was required.

Uprating isn’t new

Calvert Cliffs from landThe first uprate as we now know them was performed at Calvert Cliffs (photo seen at the top of this article and here at left), and actually occurred right after the plant was completed. Originally these two Combustion Engineering pressurized water reactors were rated at 2560 MWt/810 MWe for Unit 1 and 2560 MWt/825 MWe for Unit 2; the units entered commercial operation May 8, 1975, and April 1, 1977, respectively. In 1976, before the second unit came on line, Baltimore Gas and Electric had applied to the Nuclear Regulatory Commission to increase the ratings of both units to 2700 MWt as a “stretch uprate,” which was permitted (after careful analysis) in 1977.

This began a long period of what were mainly stretch uprates; the first extended uprates in the late 1990s did not exceed in percent power some of the stretch uprates of earlier years. Large uprates began after the turn of the century with some as high as 15 percent to 20 percent.

I mentioned that there was a “present sense” of uprates—which began in 1977. There was a time during the early years of operation of nuclear plants that provisional licenses at lower-than-designed power ratings were issued. Plants “tested out” at these provisional ratings, then later were re-licensed to increase power to the full designed level. One of my previous articles for the ANS Nuclear Cafe, describing Pathfinder Atomic Power Plant, mentioned (for the first time anywhere) that the plant originally tested at a provisional power rating, as one example. This was occurring in the 1960s.

So the natural question—really an aside, but worth asking—is this: “What was the first uprate?” My answer has to be N.S. Savannah, 1964. The ship was originally given an operational limit of 69 MWt, so that the original actual core thermal limit of 74 MWt would not be exceeded. It was found very early in her operation that this was not enough power to allow for full propulsion capability (not just her rated continuous 20,000 shaft horse power/SHP but her overload of 22,000 SHP) and full hotel loads. Babcock & Wilcox performed extensive analysis to allow raising the core operational limit to 80 MWt, which was done when the ship returned to service with American Export Isbrandtsen Lines. Some equipment modification was performed concurrently, but no major modifications were required—thus, this would have been a “stretch” uprate.

What now?

I was quite surprised, looking at the tables of nuclear plants, to see that there was really no tabulation of how many had received uprates—so I printed a list and laboriously marked off all the uprates at still-operating plants. Here are my totals by NRC regions.

In Region I, 7 of 26 total reactors have received extended power uprates; 17 have had stretch uprates and 16 have had MUR uprates. (Yes, some have had one, two, or all three at one reactor over the years.) Wow, I thought, that leaves a lot of uprating, even if only potentially likely.

In Region 2, 8 of 32 have received extended power uprates, 22 have received stretch uprates, and 15 have had MURs.

In Region 3, 9 of 23 have received extended power uprates, 9 have received stretch uprates, and 8 have had MURs.

In Region 4, 3 of 19 have received extended power uprates, 11 have received stretch uprates, and 8 have had MURs.

Looking at these figures, there’s a LOT of capacity theoretically left in U.S. nuclear plants in terms of uprates—even though they’ve dropped off in recent times. Only 27 of 100 US reactors have received extended uprates. Way back in 2003, the last time everyone was all agog over nuclear plants because of lowering carbon limits, the Nuclear Energy Institute predicted that U.S. nuclear plants could theoretically add over 10,000 MWe without building any new plants—and of that, about 6500–8500 MWe could come from uprates. (That’s on top of the 6908 MWe already added since 1977 by uprates, by the way.) Considering the totals we’ve just seen as to how many plants have not had the largest type of uprate, and seeing how many could still receive stretch uprates, that figure might roughly hold.

(Note: Yes, I’m aware that some plants included in the total uprates since 1977 have shut down and, yes, I’m aware that not every nuclear plant in the United States is in a location where uprating makes economic sense. Or hasn’t until now.)

I think that as we enter into discussions about the EPA regulations, carbon emissions, and nuclear energy, we should talk about nuclear plants in multiple senses—yes, adding small modular reactors into the mix makes good sense and,,yes, completing selected unfinished nuclear plants makes good sense in other spots. But now, we might wish to inject uprating more nuclear plants into the mix; perhaps we might see some reconsideration beyond the very few current plans for uprates (the NRC expects ZERO extended or stretch uprate applications from now through at least 2017), depending on how the carbon limits, and penalties, play out.

Note: Uprates for other reactors have been applied for and are in process; Peach Bottom-2 and -3 have extended power uprates planned by the NRC for final approval in September of this year; the only other extended power uprates, for Browns Ferry-1, -2, and -3 are however all on hold. Similarly, MURs for Oconee-1, -2, and -3 are all on hold, and in the last two years a number of planned uprate projects have been cancelled or deferred, such as at Limerick and La Salle.

Further note, just for “nukes”: Yes, for all you sharp-eyed older folks out there, those are indeed Westinghouse KX-24 Hi-Shock meters you saw above, for the power range NIs on SAVANNAH. Her control panel is a mix of these, GE DB40 meters, and Bailey vertical or edge type meters.

Radiation Health Effects for Medical Doctors

Misinformation about radiation health effects does not just affect the nuclear industry and dramatically increase the costs associated with all nuclear energy technologies. It is also having a deleterious effect on the beneficial use of radiation and radioactive materials in medical diagnosis and treatment.


Throughout their training programs, medical doctors have been taught to do everything they can to minimize radiation exposure. This message has become so intense in recent decades that many medical professionals shy away from ordering tests that would help them do their jobs better and provide better patient outcomes.

Nuclear Engineering Students Among “Most Impressive” at MIT

Gail Marcus was pleased and proud to discover that three nuclear engineering students were profiled in a group of only fourteen students identified as among the most outstanding at MIT last year.  She notes in Nuke Power Talk that this is an impressively high percentage in an already elite group, and she considers this a very positive sign for the future of the nuclear industry.

EPA Hits Nuclear Industry with Kryptonite

EPA’s latest proposed emissions rule for nuclear power plants focuses on a non-issue that has never been a problem; Kr-85.  Kr-85 is a noble gas that cannot react with anything, can’t form chemical compounds or even individual molecules, and can’t enter biological pathways.  Kr-85 can’t do anything but dissipate immediately upon leaving the reactor.

Why on Earth is China Nervous about Plutonium in Japan?

China is nervous about Japan making atomic weapons and has complained to the International Atomic Energy Agency that Japan has over 1,400 pounds of plutonium that it did not report.  This is actually amusing since this Pu cannot be made into weapons.  Also funny is China’s faked outrage.

China could complete 9 nuclear reactors in the next 7 months

By the end of 2014, the number of reactors in the country is expected
reach 30, bringing the total nuclear capacity to around 27 GWe. In
2015, capacity should reach 36 GWe, as a further eight reactors are
brought online. 18 units are expected to start up within the next two
years, taking nuclear capacity close to the projected 40 GWe figure.

Spent Fuel Pool Fire Risk Drops to Zero Months After Shutdown

Rod Adams addresses the real issues that concern operation and maintenance of spent fuel pools at nuclear power plants in this thorough article.  The constant effort on the part of some anti-nuclear activists to make spent fuel pools into a looming threat is dispatched in detail; the realities are presented so that actual risk may be perceived, and once understood, placed in perspective.

Pathfinder – A Path Not Taken

Will Davis presents a history of one of the most unusual commercial nuclear power plants ever built – a boiling water reactor capable of producing highly superheated steam.  The reasons for its failure are explored, as is some not-before-seen history.  For those interested in placing SMR’s at existing power plant sites, this post might be quite interesting – and important.
