An Ethos of Nuclear Reactor Safety

By Sherrell R. Greene

The commercial nuclear power industry has a remarkable safety record despite lingering images from the accidents at Three Mile Island and Fukushima Daiichi. This record is the legacy of a community of nuclear power plant designers, operators, and regulators who, though imperfect, were committed to the safety of the commercial nuclear power enterprise.

The generation of experts who designed and built our current commercial nuclear fleet is no more. The generation of experts who “cut their teeth” in the post-TMI era is now retired or nearing retirement. Thus the mantle of nuclear safety guardianship is now passing to a new generation who will carry the responsibility of ensuring the safety of future nuclear power plant designs and of the future commercial nuclear fleet.

What has history taught us about the way a nuclear safety expert should approach his or her profession? It is the author’s view that the appropriate Ethos of Nuclear Reactor Safety (the fundamental guiding beliefs and values of a reactor safety professional) incorporates five fundamental ideals:

  1. An acute sense of one’s responsibility to society. Nuclear power is the only energy technology available today with a realistic potential to supply abundant electricity to billions of people around the world who are living with little or no access to it. Nuclear power is also one of the few technologies that, if implemented poorly, has the potential to prevent our neighbors from ever returning to their communities and homes. These two realities should provide strong motivation to those who aspire to be reactor safety professionals.
  2. A chronic sense of uneasiness. The reactor safety professional must have a persistent questioning attitude regarding what we know, what we know that we don’t know, and what we don’t know that we don’t know (the so-called “known unknowns” and the “unknown unknowns”).
  3. A zeal for fundamental understanding. The reactor safety professional must have a passion for, and the skills to, integrate experimental data, simulation and analysis, and operational experience to arrive at a science-based understanding of the facts.
  4. A willingness to challenge the status quo and the establishment. The reactor safety professional must possess the “courage of their convictions”—and be willing to challenge the status quo and the establishment (both industrial and regulatory) when instinct and understanding compel action.
  5. A scientific and technical humility. A reactor safety professional must have a “healthy respect” for the limits of our knowledge and the wisdom to operate within these limits. He or she must be unafraid to ask and answer the question, “What if I am wrong?

This posting is an excerpt from a paper entitled “The Canary, The Ostrich, and The Black Swan: An Historical Perspective On Our Understanding of BWR Severe Accidents and Their Mitigation,” to be published in a May 2014 special edition of the ANS journal Nuclear Technology that will focus on Fukushima lessons learned.

New Books

75 Years with Nuclear Fission (a reprint of “50 Years with Nuclear Fission”)  Although many of the pioneers who contributed to the 1989 ANS 75years!conference celebrating the 50 years with nuclear fission have passed away, we celebrate their words and contributions at this year’s Winter Meeting by offering a special reprinting of  “50 Years with Nuclear Fission.” Industry pioneers such as Edoardo Amaldi, Georgy Flerov, Siegfried Fluegge, Bertrand Goldschmidt, Rudolf Peirels, Pavle Savić, Glenn Seaborg, Emilio Segre, Edward Teller, John Wheeler, and Walter Zinn will have their words resonate again in this special reprint edition.

The Never-Ending Challenge of Engineering: Admiral H. G. Rickover in his Own Words, compiled by Paul E. Cantonwine  This book is a practical and philosophical look at the principles used by engineers from the perspective of one of America’s greatest engineers, Admiral Hyman George Rickover. He is an icon Rickover NEVER-ENDING CHALLENGE cover imagein the history of nuclear power, and one of his greatest contributions was to develop nuclear power technology to meet much higher safety and quality standards tha past technological developments. The record of safety in Rickover’s nuclear Navy and in the U.S. commercial nuclear industry is unique in the history of power technology.
 
Radiochemical Technology in Nuclear Power Plants, by Chien C. Lin  This  book is a revision of “Radiochemistry in Nuclear Power Reactors,” published in 1996 by the National Research Council. The new boolinbook!k reflects certain changes and improvements from the 1996 edition, dealing with two types of light water reactors—boiling water reactors and pressurized water reactors—and includes a new chapter on radiochemistry fundamentals that provides materials for those who have not been previously exposed to basic radiochemistry in college. Also included are discussions of applications and more sophisticated techniques that have been developed in the past few years, updated data and information on activated corrosion products and radiation buildup control, and more details about fission product measurements and fuel integrity failure evaluation. In addition, at the end of the book, a number of exercises are provided for the reader to practice solving problems that may be faced during routine work in a nuclear power plant.

Nuclear Reactor Theory, by George Bell and Samuel Glasstone  ANS Nuclear Reactor Theory cover imagehas reproduced the long out-of-print Nuclear Reactor Theory, thanks to the Department of Energy, which holds the book’s copyright. The book explains the most important physical concepts and mathematical methods commonly used in predicting the behavior of neutrons in nuclear reactors. It serves as an excellent introduction to reactor theory for physicists, mathematicians, and engineers, and was written by two pioneers in the nuclear field. This seminal work is a must for any student of nuclear theory.

Co-chairs Jane LeClair and Patrick Berry

Co-chairs  Jane LeClair and Patrick Berry joined General Chair Audeen Fentiman and guest speaker Admiral (Ret.) Robert F. Willard, president and CEO of the Institute of Nuclear Power Operations, to open the plenary session. Numerous speakers, including ANS president-elect and Excel Services president and CEO Donald Hoffman, discussed the purpose of the CONTE 2013 conference and the unique opportunity the conference represented to bridge the gap between industry and education. CONTE 2013 featured many examples of the use of advanced simulation software, the role of leadership and mentoring in the nuclear industry, as well as the focus on quality, efficiency, and safety in the post-Fukushima nuclear era.
