Construction in Aomori, such as TEPCO Intermediate storage facility “Passed examination” Regulatory Commission

In order to temporarily store spent nuclear fuel that continues to accumulate on the site of a nuclear power plant, the Nuclear Regulatory Commission has compiled a review document showing that TEPCO and others have passed the examination for an intermediate storage facility under construction in Aomori Prefecture that meets regulatory standards.

The intermediate storage facility is for temporary storage of spent nuclear fuel that continues to accumulate in the storage pool of the nuclear power plant, and TEPCO and Nippon Nuclear Power Co., Ltd. are under construction in Mutsu City, Aomori Prefecture.

Six years ago, the Nuclear Regulatory Commission reviewed whether it conformed to the new regulatory standards, and in September, it drafted a draft examination document showing its de facto passing.

On The 11th, public comments were discussed to solicit opinions from the general public, and it was reported that there were questions such as whether containers for nuclear fuel could withstand earthquakes and tsunamis.

In this regard, the Regulatory Commission expressed the view that safety is ensured due to the strength of the container, etc., and formally compiled a review document showing that it had passed the regulatory standards review.

The intermediate storage facility has a capacity to store approximately 3000 tons of spent nuclear fuel, and is expected to start operations in the next fiscal year after the countermeasure work has been completed.

With regard to spent nuclear fuel, the capacity of storage pools is approaching its limit at nuclear power plants of other power companies, and companies are busy securing storage facilities.

Intermediate Storage Facilities and Nuclear Fuel Cycle Policy

The intermediate storage facility for spent nuclear fuel was originally not expected by the government’s nuclear fuel cycle policy.

Electric power companies were scheduled to transport spent nuclear fuel generated by the operation of nuclear power plants throughout Japan to reprocessing plants in Roksho Village, Aomori Prefecture.

However, the reforess processing plant has been repeatedly postponed due to troubles and scandals, and the current completion schedule is in the next fiscal year, and it is still in a situation that cannot be processed.

For this reason, spent nuclear fuel that cannot be transported to reprocessing plants continues to accumulate in the storage pools of nuclear power plants in various regions.

There are a total of 21,400 tons of storage pools at nuclear power plants nationwide, including nuclear power plants in Fukushima Prefecture, which will be decommissioned, but as of September, approximately 75% of the total of 16,060 tons have already been filled.

When the storage pool was full, fuel could not be removed from the reactor, and it became difficult to continue operation, so a new facility for temporary storage of spent nuclear fuel, that is, an intermediate storage facility, was needed.

The intermediate storage facility under construction in Aomori Prefecture, which passed the 11th screening, is for spent nuclear fuel from TEPCO and Japan Nuclear Power Company.

Electric power companies other than these two companies are also moving to secure storage facilities, but Kansai Electric Power Co., Kyushu Electric Power Co., and Shikoku Electric Power Co., Ltd., which have already restarted their nuclear power plants after the Fukushima nuclear power plant accident, are more serious about the problem.

Kyushu Electric Power Co. and Shikoku Electric Power Co. are planning to build a new storage facility on the site of the nuclear power plant.

Kansai Electric Power Co., Ltd., like TEPCO, plans to create an intermediate storage facility outside Fukui Prefecture, where the nuclear power plant is located, and will show potential sites during this time.

The governor of Fukui Prefecture is seeking to present a candidate site as a prerequisite for agreeing to restart the nuclear power plant.
