"Life in the post-Fukushima era for nuclear regulatory agencies in Japan and the United States is not easy. In Japan, the Nuclear Industrial Safety Agency (NISA) is in hot water over revelations that it stacked the deck at public meetings with employees of the nuclear utilities it is supposed to regulate.
Two utilities told the Japanese government that they complied with requests from NISA in 2006 and 2007 to send their employees to public meetings to support proposed licensing decisions. In response to these revelations, Japanese Prime Minister Naoto Kan has questioned whether NISA should continue to exist in its present form. He also called for a phaseout of dependence on nuclear power for the Japanese economy.
In the United States, an aggressive plan to apply “lessons learned” from Fukushima to the regulation of the U.S. fleet of reactors has hit the rocks. The so-called 90-day report, supported by the controversial chairman of the U.S. Nuclear Regulatory Commission (NRC), will not be quickly acted on due to opposition from three other commissioners."
