TEPCO discovers after 5 years that it could have quickly declared Fukushima plant meltdown
By JIN NISHIKAWA/ Staff Writer/Asahi Shimbum
Nearly five years later, Tokyo Electric Power Co. said Feb. 24 that it has discovered a guideline in its operational manual that would have allowed it to announce meltdowns in the nuclear disaster in only days instead of the two months it actually took.
TEPCO apologized for failing to be aware for such a long time of the guideline on how to declare meltdowns at its Fukushima No. 1 nuclear power plant, triggered by the Great East Japan Earthquake and tsunami on March 11, 2011.
While the utility announced that reactor cores had been damaged at the No. 1 and No. 3 reactors by March 14 and at the No. 2 reactor by March 15, it did not admit that meltdowns had occurred in the three reactors until May 2011.
Based on its “nuclear disaster countermeasures manual,” which was revised 11 months before the disaster, the utility could have instead declared meltdowns at the three reactors by those dates, it said.
“We sincerely apologize for failing to confirm the presence of the guideline in the manual for five years,” a TEPCO spokesperson said Feb. 24.
