Just when TEPCO and the Japanese government are coming clean of what they knew all along - that it was a core meltdown in all three reactors at Fukushima, the US Nuclear Regulatory Commission announced that it will stop monitoring Fukushima on the 24-hour/day basis because the situation is now "stable" and continues to "improve".
The NRC must have known all along about the core meltdown, if what they claimed was true, that they had access to all the information that TEPCO had.
From NY Times (5/16/2011):
The United States Nuclear Regulatory Commission said on Monday that its 24-hour operations center had stopped monitoring the nuclear reactors at the Fukushima Daiichi plant because the situation there had improved. “The conditions at the Japanese reactors are slowly stabilizing,” said William Borchardt, the agency’s chief staff official. “As conditions have continued to improve and the Japanese continue to implement their recovery plan, the N.R.C. has determined that it is time to adjust our response,” he said. The agency still has a team of engineers in Tokyo, he said. Mr. Borchardt said last week that the condition of the reactors was “static but not stable.”
