Shikoku Electric Power Ikata Nuclear Power Plant Dry Storage Facility Passed the examination by the Nuclear Regulatory Commission September 16 14:46
The Nuclear Regulatory Commission has passed the examination of a dry storage facility that does not use water for cooling, which is planned by Shikoku Electric Power Company to temporarily store the ever-increasing amount of spent nuclear fuel at the Ikata Nuclear Power Station in Ehime Prefecture. We have compiled the examination documents shown.
At the Ikata Nuclear Power Plant of Shikoku Electric Power Co., Inc. in Ehime Prefecture, we plan to construct a dry storage facility that temporarily stores spent nuclear fuel, which continues to increase due to the restart of Unit 3, in a special container that removes heat by air cooling without using water. I am.
Regarding this, the Nuclear Regulatory Commission, which has been reviewing for two years, has compiled a review report showing that it passed the review at the regular meeting on the 16th, saying that there are no problems with earthquake resistance and ability to block radiation. ..
Spent nuclear fuel is scheduled to be processed sequentially at a reprocessing plant in Aomori Prefecture, but due to the delay in full-scale operations, it remains impossible to carry it out at nuclear power plants nationwide.
According to Shikoku Electric Power Co., Inc., the pool that stores the spent nuclear fuel of the Ikata nuclear power plant has only about 240 remaining spaces, and if it is left as it is, it may fill up in about 6 years, so about 1200 units will be stored from the 6th year of Reiwa. The policy is to start the operation of a dry storage facility that can be used.
Unlike the current mainstream method of cooling in a pool, the dry storage facility does not use water and does not require a power source, so it is said to have a simple structure and is resistant to earthquakes, and electric power companies are promoting its introduction.
