TEPCO admits error in screening report

TEPCO admits error in screening report

Japan's Nuclear Regulation Authority is demanding an explanation from Tokyo Electric Power Company.

TEPCO has admitted to submitting inaccurate information from calculations 3 years ago on plans for restarting two of its nuclear reactors in Niigata Prefecture.

The regulator is in the final stages of screening the No.6 and 7 reactors at TEPCO's Kashiwazaki-Kariwa plant.

The reactors must meet new government requirements introduced after the 2011 Fukushima disaster.

Regulators gathered on Tuesday for discussions with TEPCO about buildings at the plant to be used as headquarters in an emergency.

TEPCO officials admitted one of the buildings lacked the necessary quake-resistance in all 7 of the company's tests.

They had earlier said that the building had failed 5 of the 7 tests. They said they would not use the building.

They blamed the discrepancy on a failure by the civil engineering department to convey test results to the equipment design department.

The regulators noted the lack of coordination between TEPCO departments on the impact of soil liquefaction on breakwaters.

They called the mistakes unacceptable, and they're demanding that TEPCO provide details and countermeasures.
