TEPCO files for Niigata N-plant check

JAPAN - Tokyo Electric Power Co. filed a request Friday with the Nuclear Regulation Authority for safety checks of the Nos. 6 and 7 reactors at its Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture.

Safety checks are mandatory to restart nuclear reactors.

Four other utility companies in July filed for safety checks of 12 reactors at six nuclear power plants.

The reactors that TEPCO applied to have safety inspections carried out on are boiling-water reactors like those at TEPCO's crippled Fukushima No. 1 nuclear power plant.

This is the first time a safety check request has been filed for boiling-water reactors.

TEPCO President Naomi Hirose said Friday morning that the utility is preparing to file safety-check applications for other reactors.

A major focus of safety inspections will be on the performance of filter-equipped ventilation devices, which are nonexistent at the six other plants, and on faults running below the plant.

Takafumi Anegawa, a managing executive officer of TEPCO, visited the NRA at 9:30 a.m. Friday to submit a 6,600-page application. After turning in the document, he told reporters that the utility "compiled the document after studying measures one by one utilizing lessons learned from the crisis [at the Fukushima plant].
