U.S. Nuclear Plants with Design Concerns
23 U.S. Reactors with BWR Mark I type design
Concerns raised as early as 1972 about the BWR Mark I
Recommendations from late 1970s and early 1980s to install hardened, filtered vent system
6 other reactors with ice condenser emergency cooling system
Nuclear Regulatory Commission conducted 90 day review of all plants

Three Pillars to Japan’s Energy Policy Prior to the F-D Accident
• Energy security• Use of market mechanisms to meet energy needs• Reduce greenhouse gas emissionsPrior level of and goal for nuclear power• Nuclear power provided about 30% of electricity• Plans for up to 50% on or about 2030• Now many want phase out or at least much
reduced role

“Safety Myth”• Cover ups of safety
violations• A few dozen
violations at Fukushima Daiichi alone
• Warning in 2009 about potential for massive tsunami
![Page 13: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/13.jpg)
A Role for Non-Governmental Organizations: U.S.-Japan Nuclear Working Group
• Trilateral partnership among the Maureen and Mike Mansfield Foundation, the Federation of American Scientists, and the Sasakawa Peace Foundation
• Formed in summer 2011• Just recently completed last
outreach in October 2013
![Page 14: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/14.jpg)
“Made in Japan”• Main conclusion of
Japanese Diet Commission’s report, published in summer 2012 and headed by Dr. Kiyoshi Kurokawa
• The accident was preventable.

What is the Working Group Doing Now and will do in the Future?
• Help with exchanges between regulatory officials and Congress and Diet members
• Continue with analytic work• Encourage tri-national cooperation: ROK, Japan, U.S.

The Need for Better Public EducationOp-Ed Contributor: David Ropeik
“Fear vs. Radiation: The Mismatch,” published: October 21, 2013 “Without a much broader and persistent effort by various branches and levels of government to help the public understand the actual biological effects of radiation, we will continue to face the threat of deep historic nuclear fears that simply don’t match the facts.”

Another View and Why We Need Better Public Education
Excerpts from Dr. Helen Caldicott’s October 30, 2013 NYT letter in response to Ropeik’s op-ed:
“Large areas of the world are becoming contaminated by long-lived nuclear elements secondary to catastrophic meltdowns: 40 percent of Europe from Chernobyl, and much of Japan. …
A New York Academy of Sciences report from 2009 titled “Chernobyl” estimates that nearly a million have already died from this catastrophe. In Japan, 10 million people reside in highly contaminated locations.”

Will there always be risk?• “. . . there is no way to eliminate all
risk entirely . . . despite all the design improvements that we conceive, systems still fail; despite all the training and lessons learned in exercises that are conducted, human beings will still make mistakes, particularly when confronted with once-in-a-lifetime events,” Former NRC Chairman Richard Meserve

“Normal Accidents”Thesis of Charles Perrow, Sociologist at Yale
![Page 27: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/27.jpg)
Will Fission Reactors be Phased Out?"I’ve never seen a movie that’s set
200 years in the future and the planet is being powered by fission reactors—that’s nobody’s vision of the future. This is not a future technology. It’s an old technology, and it serves a useful purpose. But that purpose is running its course.” Former NRC Chairman Gregory Jaczko, as quoted in IEEE Spectrum

What Needs to be Done to Make Nuclear Power Safer?
• Building passive safety and advanced active safety systems
• Instilling safety culture• Assuring independent regulation• Researching better technologies and better
understanding of human behavior• Factoring in Beyond Design Basis Events
![Page 29: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/29.jpg)
For example, AP1000
![Page 30: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/30.jpg)
Example of Enhanced Active Safety Systems, EPR

Reactions from Various Countries• Polls showed decrease of
public support—generally not surprising
• Countries against became more against
• Countries in favor stayed in favor except for Japan, which reversed its position
• U.S. still in favor but economics are the main problem for new nuclear plants
• Positive sign: Beijing temporarily halted construction in 2011 needs to deal with “safety gap”
• China seemed to be building too fast and had not kept pace with training high quality workforce
![Page 32: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/32.jpg)
Tale of Two Countries
![Page 33: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/33.jpg)
Reversal of the Reversal• Soon after accident,
German Chancellor Merkel reversed previous reversal that had extended life of reactors.
• In April 2011, unveiled 6 point plan to phase out nuclear power in 10 years
![Page 34: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/34.jpg)
Is the German Plan Smart for Japan?• Germany can buy electricity
from and sell to other grid-connected European countries, including France with almost 80% of electricity from nuclear power
• In summer and winter, France typically imports from Germany and vice versa in spring and fall.
• Japan is not grid connected to other countries.
• Unlike Japan, Germany still has significant deposits of coal although this “brown” coal is especially dirty
• Germany has a natural gas pipeline network to other countries
![Page 35: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/35.jpg)
Spent Nuclear Fuel Pools• Most of the almost 70,000
tons of spent U.S. nuclear fuel stored in deep pools of water
• Many other countries in similar situation
• No permanent storage available
• Companies reluctant to spend money on dry cask storage
• Removal of SNF from Fukushima reactor #4 started in November
![Page 36: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/36.jpg)
Dry Cask Storage• Estimated $3 to $5
billion to transfer all overcrowded spent fuel to dry casks
• Germany applies this method
• Used to a limited extent in the United States and Japan (proven at F-D)
![Page 37: Post-Fukushima Daiichi Nuclear Accident: Implications for Japan and the World](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814577550346895db24816/html5/thumbnails/37.jpg)
Use of Plutonium-based Fuels• Reactor #3 at Fukushima was fueled with mixed
oxide (MOX) fuel, which contains plutonium oxide• Japan has invested about $28 billion in a plutonium
recycling program New policy expected in Dec. 2013 or soon thereafter
• U.S. has refrained from reprocessing spent fuel to use plutonium since the Carter administration
• But the United States has planned to dispose of weapons-grade Pu by using MOX this may change

Parting Thoughts from Fermi
“The history of science and technology has consistently taught us that scientific advances in basic understanding have sooner or later led to technological and industrial applications that have revolutionized our way of life…What is less certain and what we all fervently hope is that man will soon grow sufficiently adult to make good use of the powers that he acquires over nature.”
