Nuclear storage facility effectively approved

Japan's nuclear regulator has effectively approved safety measures at a facility to temporarily store spent nuclear fuel.

The Nuclear Regulation Authority issued a draft assessment for the facility on Wednesday.

The facility is currently being built by Tokyo Electric Power Company and the Japan Atomic Power Company in Mutsu City, Aomori Prefecture.

They applied for approval by the nuclear watchdog in 2014.

They raised their estimate for the maximum seismic movement the facility can withstand from 450 gals to 620 gals and laid out measures to prepare for a 23-meter tsunami.

The nuclear regulator said it will give official approval after gathering public opinion.

The facility can store about 3,000 tons of spent nuclear fuel. The utilities plan to start operating it in fiscal 2021.

Besides the two firms, Kyushu Electric Power Company and Shikoku Electric Power Company are also planning to build new storage facilities within their nuclear plants.
