The Nuclear Regulation Authority (NRA) is failing in its oversight mandate by not extending its investigations into potentially flawed major components in Japanese reactors with a mere paper exercise, warned Greenpeace. Japanese-manufactured major components installed in French nuclear reactors are currently under investigation by the country’s safety regulator due to the discovery of excess carbon in the steel, which reduces the material’s toughness and increases the risk of catastrophic failure and reactor core meltdown. At its meeting this morning, the NRA commissioners announced that they had concluded there was no risk of excess carbon in reactors in Japan. However, not able to ignore reality completely, the NRA also stated that the situation in France with Japanese components under investigation means they will have to continue to review the situation.
