Kawauchi Nuclear Power Station # 1 to stop on March 16 23:30 on March 15 due to counter-terrorism measures
Kyushu Electric Power's Sendai Nuclear Power Station Unit 1 in Kagoshima Prefecture will be shut down on April 16 because facilities such as anti-terrorism measures, which are required to be installed according to new national regulations, will not be completed by the deadline. This is the first time that nuclear power plants will be shut down based on new regulatory standards, with plans to shut down the reactor.
The Nuclear Regulatory Commission has set up facilities with spare equipment to protect the reactor during emergencies such as terrorism and aircraft collisions, based on new regulatory standards created after the Fukushima Daiichi nuclear accident. Must be completed within five years after the construction plan is approved.
Regarding this, Kyushu Electric Power has decided that the completion of the facility at the Kawauchi Nuclear Power Plant will not be completed by the deadline, and decided to stop the operation in a form to accelerate the periodic inspection, and to reduce the output of the reactor from around 2:30 am on March 16. Start lowering work.
The power generation and transmission will be stopped at around 9 am on the 16th, and the reactor will be shut down and stopped at around 1 pm four hours later. Kyushu Electric Power plans to complete the facility by December and start the reactor after being inspected by the regulatory committee.
This is the first time that an operating nuclear power plant will be shut down based on a new regulatory standard created seven years ago.
Kyushu Electric Power plans to suspend operation of the Kawauchi Nuclear Power Station Unit 2 in May, assuming that facilities such as counter-terrorism measures are not on time.
Other nuclear power plants that are about to expire
Several nuclear power plants are expected to be unable to complete facilities, such as counter-terrorism, required by new regulatory standards in time.
The deadline for the Kyushu Electric Power's first Kawauchi nuclear power plant to be stopped this time is 17th of this month. In addition, if the deadline is near, the second Kawauchi nuclear power plant will be in May, the third Takahama nuclear power plant in Kansai Electric Power in Fukui Prefecture will be in August, the fourth Takahama nuclear power plant will be in October, and then to Ehime Prefecture. A certain Shikoku Electric Power's Ikata Nuclear Power Station Unit 3 is set for March next year.
In addition, the completion of the facilities at Takahama 1 and 2 at the Kansai Electric Power Company in Fukui Prefecture, Unit 3 at Mihama, and Units 3 and 4 at Oi Ii in Fukui Prefecture may not be completed by the deadline from next year. You.
Electricity companies will stop the operation of the nuclear power plant and start periodic inspections before the deadline expires, and urgently work on completing the facility.
With "special serious accident handling facilities"
This facility is called a `` special accident response facility, '' and is designed to cool the backup control room and reactor in case of a terrorist attack or an aircraft falling and destroying important facilities. It is equipped with a power supply and a pump.
Based on the lessons learned from the accident at TEPCO's Fukushima Daiichi Nuclear Power Station, a new regulatory standard created seven years ago required the installation. The facility is to be located more than 100 meters away from the reactor, but the exact location has not been disclosed due to counter-terrorism.
