Two Japanese power companies show interest in a spent nuclear fuel storage facility in Aomori Prefecture, potentially addressing storage capacity issues.

Why it matters

This development could help alleviate storage capacity concerns for spent nuclear fuel as Japan's nuclear reactors resume operations.

Two Japanese power companies want to use a special place to store used-up parts of nuclear power plants. This helps them have enough space for these parts before they are moved to another place.

Analysis

{"

Kansai Electric's Situation":"> Kansai Electric currently stores spent fuel in pools at its Mihama, Oi, and Takahama nuclear power plants in Fukui Prefecture. The company plans to build a dry storage facility to secure sufficient capacity for the time being.","

Tohoku Electric's Situation":"> Tohoku Electric has spent pools at its Onagawa nuclear plant in Miyagi Prefecture expected to reach maximum capacity around November 2028. The company plans to start building a dry storage facility this month and begin operating it in March 2028.","

Mutsu Facility Details":"> The Mutsu facility currently accepts spent nuclear fuel only from Tokyo Electric Power Company Holdings and Japan Atomic Power. Aomori Governor Soichiro Miyashita has stated that adding companies to the list of nuclear plant operators that use the interim storage facility is not envisaged under the agreement with local governments hosting the facility.","

Dry Storage Facilities":"> Kansai Electric plans to build a dry storage facility to secure sufficient capacity for the time being. Tohoku Electric plans to start building a dry storage facility this month and begin operating it in March 2028.","

Rokkasho Plant":"> The nuclear fuel reprocessing plant in Rokkasho, Aomori Prefecture, remains under construction and its completion has been repeatedly postponed."}

The Upside

This move could help ensure that spent nuclear fuel is stored safely and efficiently, reducing the risk of accidents and environmental damage.

The Downside

There could be delays or issues with the dry storage facilities, and the Rokkasho plant's completion may still be delayed, which could affect the overall storage plan.
