Approved decommissioning plan for Oii Nuclear Power Plant Unit 1 and Unit 2 for the first time on December 11 at 19:15 with over 1 million kilowatts
On the 11th, the Nuclear Regulatory Commission approved a plan that summarized Kansai Electric Power's decommissioning over about 30 years for Unit 1 and Unit 2 of the Ooi Nuclear Power Station in Fukui Prefecture. This is the first approval for a decommissioning plan for a nuclear power plant with an output of over 1 million kilowatts.
Forty years after the start of operation, Osai Nuclear Power Unit No. 1 and No. 2 Kansai Electric Power decided on a decommissioning maneuver as safety measures for re-operation were technically difficult, etc. I have applied for a plan that summarizes the procedure for decommissioning over the years.
On the 11th, this was discussed at the regulatory committee and the plan was approved as there were no operational problems.
According to the plan, decontamination of pipes and demolition of buildings will be completed by 2048.
In addition, the nuclear fuel that can still be used among the used nuclear fuel can be reused in Units 3 and 4 that have been restarted. “Building” includes the fact that it will not be demolished until the start of the operation of the new countermeasures.
This is the first approval for a decommissioning plan for a large nuclear power plant with an output exceeding 1 million kilowatts.
Mr. Sarada, the chairman of the Nuclear Regulatory Commission, was asked about the cautions for future work, and he said, “It is necessary to proceed with work so as not to affect Units 3 and 4 that are restarting.”
Chairman, Nuclear Regulatory Commission
Regarding the approval of plans for decommissioning of Daiichi Nuclear Power Station Unit 1 and Unit 2, Chairman Toyoshi Sarada of the Nuclear Regulatory Commission touched on points to keep in mind when proceeding with decommissioning. Units 4 and 4 are in operation, but large-scale decommissioning work will not start immediately, but it should not interfere with the operation of Units 3 and 4. And in the unlikely event of an emergency, 3 It ’s important not to affect the response of Unit 4. ”
21 decommissioning reactors after the Fukushima Daiichi nuclear power plant accident
After the accident at the Fukushima Daiichi Nuclear Power Station, the nuclear power plants that decided to decommission were 21 nuclear power plants, including Daiichi Nuclear Power Units 1 and 2 that were approved by the Nuclear Regulatory Commission on the 11th. climb.
The first Tsuruga nuclear power plant in Fukui Prefecture,
▽ Mihama Nuclear Power Station Units 1 and 2
▽ Units 1 and 2 from Oihara.
The first Shimane nuclear power plant in Shimane Prefecture.
Located in Saga Prefecture, Genkai Nuclear Power Station Units 1 and 2.
Located in Ehime Prefecture.
The first Onagawa Nuclear Power Station in Miyagi Prefecture.
in addition,
In Fukushima Prefecture Fukushima Daiichi Nuclear Power Unit Units 1 to 6,
▽ A total of 21 nuclear power plants from 9 units of Fukushima Daini nuclear power plant.
With the exception of TEPCO's nuclear power plant in Fukushima Prefecture, most nuclear power plants have been decommissioned because the costs for safety measures required by the new regulatory standards are not commensurate.
