The Kashiwazaki-Kariwa nuclear power plant in Japan's Niigata Prefecture will not be restarted until fiscal 2022 (ending March 2023) at the earliest, Tokyo Electric Power Company (Tepco) said in a revised business plan. The company submitted the plan yesterday to the government for approval. Tepco is awaiting regulatory approval to restart units 6 and 7 at the plant.

Japan's Nuclear Regulation Authority (NRA) on 28 April approved Tokyo Electric Power Company's (Tepco's) decommissioning plan for the four boiling water reactors at the Fukushima Daiini nuclear power plant, some 11km south of the damaged Fukushima Daiichi plant. The four reactors, which began operation between 1982 and 1987, were also hit by the tsunami in March 2011 which destroyed the Fukushima Daiichi plant. They temporarily lost reactor cooling functions, but unlike the Daiichi plant, avoided meltdowns. They have since been maintained in cold shutdown.

The removal of fuel from Unit 3 began in April 2019. Courtesy Tepco. Tokyo Electric Power Company (Tepco), the operator of the Fukushima-Daiichi nuclear power station in northern Japan, has removed all 566 fuel assemblies from the storage pool of Unit 3 at the damaged facility.

“The fuel removal work from the spent fuel pool of Fukushima-Daiichi nuclear power station Unit 3 was completed with the removal of all 566 units at 13:59 on February 28,” said a statement on the company’s social media feeds.

The removal of fuel from Unit 3’s storage fuel pool began in April 2019 after several years of work to remove debris from the reactor building service floor.

The work required the removal of huge pieces of damaged equipment that fell into the pool during the explosions that hit the nuclear site in Fukushima, in the days after a March 2011 earthquake and tsunami knocked out power and emergency cooling.

The process of removing all 566 fuel assemblies from the storage pool of unit 3 at the damaged Fukushima Daiichi nuclear power plant in Japan was completed yesterday, Tokyo Electric Power Company (Tepco) has announced. Fuel assemblies have already been removed from the pool at unit 4, but such work has yet to start at units 1 and 2.

The Fukushima-Daini nuclear power station in northern Japan. Water overflowed from spent nuclear fuel storage pools at the Fukushima-Daiichi and Fukushima-Daini nuclear power stations operated by Tokyo Electric Power Company following an earthquake that struck off the coast northeastern late on Saturday night.

The pools are at the Unit 5 and 6 reactor buildings at Fukushima-Daiichi, which are being decommissioned, and the Unit 1 reactor building at Fukushima-Daini, which is set to be decommissioned.

According to the Nuclear Regulation Authority, it has been confirmed that no water leaked outside the buildings and cooling of the nuclear fuel at the two Fukushima stations has not been affected.

The International Atomic Energy Agency said it had been informed by the NRA that there was no damage to the two nuclear stations, or to a third at Onagawa, which is to the north of Fukushima in Miyagi prefecture.

The Kashiwazaki Kariwa nuclear power station in Japan. Japan’s nuclear regulator announced on 23 September that Tokyo Electric Power Company is fit to operate the Kashiwazaki Kariwa nuclear power station, based on new legally binding safety rules the company drafted and pledged to follow.

If Tepco is found to be in breach of the rules, it could be ordered to halt the station’s operations, press reports in Japan said.

Local governments must agree in the coming months to restart the seven-unit station in Niigata Prefecture, northwestern Japan.

Kashiwazaki Kariwa was not affected by the earthquake and tsunami which damaged Fukushima-Daiichi in 2011. The station’s reactors were all offline at the time following a 2007 earthquake which damaged the site but did not damage the reactors themselves.
