Southern California Edison Announces Plans to Retire San Onofre Nuclear Generating Station

Company Will Continue Its Work with State Agencies on Electric Grid Reliability

A conference call with Q&A was held by management at 12PM EST Friday for media outlets only – replay will be available at 1-888-568-0503 (USA) and 1-203-369-3476 (International), passcode 5241.

ROSEMEAD, Calif.–(BUSINESS WIRE)– Southern California Edison (SCE) has decided to permanently retire Units 2 and 3 of its San Onofre Nuclear Generating Station (SONGS).

“SONGS has served this region for over 40 years,” said Ted Craver, Chairman and CEO of Edison International, parent company of SCE, “but we have concluded that the continuing uncertainty about when or if SONGS might return to service was not good for our customers, our investors, or the need to plan for our region’s long-term electricity needs.”

Both SONGS units have been shut down safely since January 2012. Unit 2 was taken out of service January 9, 2012, for a planned routine outage. Unit 3 was safely taken offline January 31, 2012, after station operators detected a small leak in a tube inside a steam generator manufactured by Mitsubishi Heavy Industries (MHI). Two steam generators manufactured by MHI were installed in Unit 2 in 2009 and two more were installed in Unit 3 in 2010, one of which developed the leak.

In connection with the decision, SCE estimates that it will record a charge in the second quarter of between $450 million and $650 million before taxes ($300 million – $425 million after tax), in accordance with accounting requirements.

After months of analysis and tests, SCE submitted a restart plan to the Nuclear Regulatory Commission (NRC) in October 2012. SCE proposed to safely restart Unit 2 at a reduced power level (70 %) for an initial period of approximately five months. That plan was based on work done by engineering groups from three independent firms with expertise in steam generator design and manufacturing.

The NRC has been reviewing SCE’s plans for restart of Unit 2 for the last eight months, during which several public meetings have been held. A recent ruling by an adjudicatory arm of the NRC, the Atomic Safety and Licensing Board, creates further uncertainty regarding when a final decision might be made on restarting Unit 2. Additional administrative processes and appeals could result in delay of more than a year. During this period, the costs of maintaining SONGS in a state of readiness to restart and the costs to replace the power SONGS previously provided would continue. Moreover, it is uneconomic for SCE and its customers to bear the long-term repair costs for returning SONGS to full power operation without restart of Unit 2. SCE has concluded that efforts are better focused on planning for the replacement generation and transmission resources which will be required for grid reliability.

“Looking ahead,” said Ron Litzinger, SCE’s President, “we think that our decision to retire the units will eliminate uncertainty and facilitate orderly planning for California’s energy future.”

Litzinger noted that the company has worked with the California Independent System Operator, the California Energy Commission and the California Public Utilities Commission in planning for Southern California’s energy needs and will continue to do so.

“The company is already well into a summer reliability program and has completed numerous transmission upgrades in addition to those completed last year,” Litzinger said. “Thanks to consumer conservation, energy efficiency programs and a moderate summer, the region was able to get through last summer without electricity shortages. We hope for the same positive result again this year,” Litzinger added, “although generation outages, soaring temperatures or wildfires impacting transmission lines would test the system.”

In connection with the retirement of Units 2 and 3, San Onofre anticipates reducing staff over the next year from approximately 1,500 to approximately 400 employees, subject to applicable regulatory approvals. The majority of such reductions are expected to occur in 2013.

“This situation is very unfortunate,” said Pete Dietrich, SCE’s Chief Nuclear Officer, noting that “this is an extraordinary team of men and women. We will treat them fairly.” SCE will work to ensure a fair process for this transition, and will work with the Utility Workers Union of America (UWUA) and the International Brotherhood of Electric Workers (IBEW) on transition plans for the employees they represent.

SCE also recognizes its continuing safety responsibilities as it moves toward decommissioning of the units. SCE’s top priority will be to ensure a safe, orderly, and compliant retirement of these units. Full retirement of the units prior to decommissioning will take some years in accordance with customary practices. Actual decommissioning will take many years until completion. Such activities will remain subject to the continued oversight of the NRC.

SCE intends to pursue recovery of damages from Mitsubishi Heavy Industries, the supplier of the replacement steam generators, as well as recovery of amounts under applicable insurance policies.

    SCE forgets to mention the real reasons for shutting down the reactors which are

    1. SCE selected steam generators (SGs) from MHI as low bidder
    2. SCE told MHI to change the SG design from original SGs
    3. SCE told NRC the new SG design would be like the old SG design
    4. MHI designed and built lousy SGs with SCE oversight
    5. SCE installed these lousy SGs into the plant
    6. The lousy SGs started wearing out after one year
    7. One of the SGs developed a leak and SCE had to shutdown the reactor
    8. SCE and worldwide consults came up with only two solutions – replace all these SGs or operate the plant at reduced power with the hope that the wearing will stop.
    9. SCE wanted to go with reduced power operation for one reactor but NRC regulations do not allow this experiment without a formal licensing amendment.
    10. SCE decided that the formal license amendment process was too long and made the business decision for permanent shutdown of the reactors.

    SCE should not blame others for their own mess.

    FUD-slinging greens are already citing the SONGS shutdown as by safety issues — and as usual go totally unchallenged on the stage. The disgusting non-neutral manner that general media has been virtually hailing the SONGS shutdown and looking toward (aiding) others and casting doubts within energy companies and investors is sadly going to make Pandora’s Promise as inspiring and profound as a dog food commercial. Boxer and other pols have been singing over SONGS and more billions for unproven “green energy”; where are all the supposedly pro-nuke pols hiding — BEEN hiding? In a soundproof closet?? Had nuclear’s image been more positive and enlightened in the U.S. it could’ve weathered through such reactor shutdowns by financial and age factors, but that long neglected bulwark doesn’t exit and with the near promise of “green” administrations and school indocrination to come, we’d better a chance helping Ben Heard decarbonizing Australia.

    We will soon learn, in the USA, what the citizens of Germany and Japan are learning: that when a nuclear power station goes down, the price of electricity goes up, carbon emission rates go up — and the amount of press given to wind and solar generators goes through the proverbial roof.

    I’m one of those pro-nukes who thinks that renewables have an active role to play; using them as glorified fig leaves does not betoken a successful roll-out.

    And … when Pandora’s Promise opens next weekend, I’m sure the conversation in Southern California will reflect it.

    As long as we don’t have any cohesive energy policy besides “wait and see” which is basically “become 80% dependent on natural gas,” we won’t really see a nuclear resurgence. Nuclear takes long-term vision and planning and well-thought-out/understood perception of risk. Nationally, we lack these traits. We accept no perceived risk (even if it’s statistically the lowest) and don’t think very far beyond our present situation.

    It pains me to say it, but I think we are seeing the endgame of the nuclear era here. We’ve lost four units in the last year or so, Kewaunee, Crystal River 3, and now SONGS. I know SONGS and CR3 had problems, but they were solvable problems. KNPP is particularly distressing because there was absolutely nothing wrong with that plant. Technically, it was a perfectly functional unit, yet it was thrown away. We are throwing away valuable electrical infrastructure like there are a thousands tomorrows, when there aren’t. And no one seems to care, it’s like, oh, well, we’ll get over it. That kind of attitude really marks the beginning of the end.
