TOKYO (Kyodo) -- Tokyo Electric Power Co. said Wednesday it could have determined nuclear core meltdown occurred at the Fukushima plant sooner than it did following a massive earthquake and tsunami on March 11, 2011.
The utility known as TEPCO initially said reactors cores had been damaged, but did not admit until May 2011 that core meltdown occurred. Early in the crisis it said there was no basis to determine reactor core meltdown.
