菅直人は、 "原子力エネルギーは非常に危険です。" Naoto Kan: "Nuclear energy is very risky." ABC Australia's Mark Willacy confronts former Japanese Prime Minister Kan about the eight weeks of delay it took to publicly disclose there had been "meltdowns" at the Fukushima-Daiichi nuclear power plants. Kan explains why he put maximum pressure on TEPCO not to abandon the out-of-control reactors. According to Yoichi Funabashi, author of an independent report, "He saved the nation." 船橋洋一は、"彼は国を救った。" But Funabashi's report is also highly critical of Kan for micro-managing the disaster, and for delaying the release of critical safety information to the public. Kan claims NISA failed to inform him that meltdowns had occurred, and therefore Kan claims "I did not withhold anything which I knew." A 2002 book "tritium on ice" by nuclear physicist Kenneth D. Bergeron has a chapter describing what Sandia Labs, GE and NRC knew about how GE Mark 1 reactors could fail catastrophically: the detailed modelled scenario is called "Direct Containment Heating" (DCH). DCH appears to give a very good explanation of all the observed visual phenomena at Fuku-Daiichi Unit 3; a massive dirty dark grey upthrusting plume, which according to DCH theory signals the almost simultaneous failures of (i) a highly pressurized pressure vessel, and (ii) the surrounding containment structures. This mode of failure was recognized for GE Mark 1 as early as 1987, according to Bergeron. This package is ...
