Nuclear power in Japan Law, but they have been reorganized several times since their inception. Long one of the world’s most committed promoters of civilian nuclear power, Japan's nuclear industry was not hit as hard by the effects of the 1979 Three Mile Island accident (USA) or the 1986 Chernobyl disaster (USSR) as some other countries. Construction of new plants continued to be strong through the 1980s and into the 1990s. However, starting in the mid-1990s there were several nuclear related accidents and cover-ups in Japan that eroded public perception of the industry, resulting in protests and resistance to new plants. These accidents included
British nuclear testing in the United States powerful conventional explosive, EDC11. The result was that the yield was less than Tsetse, and too small to be used as the primary in the Skybolt warhead. A follow-up test of what became the basis for the WE.177 design codenamed Tendrac therefore took place on 7 December 1962, and was judged a success. Subcritical tests were tests with nuclear weapons that did not involve a nuclear explosion. Safety tests involved testing the impact of fire, shock and other accidents against live nuclear weapons. These did not intentionally involve nuclear explosions, although there was always a danger. Tim subcritical tests and
