Japan utility: Delay in declaring 'meltdown' was cover-up [View all]

"I would say it was a cover-up," Hirose told a news conference. "It's extremely regrettable."

TEPCO instead described the reactors' condition as less serious "core damage" for two months after the earthquake and tsunami on March 11, 2011, wrecked the plant, even though utility officials knew and computer simulations suggested meltdowns had occurred.

An investigative report released last Thursday by three company-appointed lawyers said TEPCO's then-President Masataka Shimizu instructed officials not to use the specific description under alleged pressure from the Prime Minister's Office, though the investigators found no proof of such pressure.

The report said TEPCO officials, who had suggested possible meltdowns, stopped using the description after March 14, 2011, when Shimizu's instruction was delivered to vice president at the time, Sakae Muto in a memo at a televised news conference. Shimizu had a company official show Muto his memo and tell him the Prime Minister's Office has banned the specific words.

Government officials also softened their language on the reactor conditions around the same time, the report said.
