Citizen Scientist: Frank von Hippel’s Adventures in Nuclear Arms Control PART 8. Nuclear-reactor Safety Again

Abstract

The Fukushima accident of 2011 pulled von Hippel back into the reactor-safety world. He was invited to join a Congressionallymandated four-year study of the lessons that could be learned from the Fukushima accident to improve the safety of US nuclear plants. During that study he learned more about both a much worse accident that almost happened at Fukushima, and about how the US Nuclear Regulatory Commission had come to use "riskinformed regulation" as a way to avoid requiring costly safety upgrades opposed by US nuclear utilities. He campaigned unsuccessfully at both the national and state levels to move the nuclear utilities away from densely packed spent fuel pools by moving fuel that had cooled for more than five years to dry-cask storage. He also promoted on-site dry-cask storage in Japan and South Korea as an alternative to reprocessing. This last chapter ends with some stories of his father, also a physicist, who would not be intimidated and who was a leader in the development of the field of materials science and engineering.
