A team of International Atomic Energy Agency (IAEA) officials are in Japan to officially launch a multi-year review of the planned release of treated water at the Fukushima Daiichi nuclear power plant. It is the IAEA's first mission as part of its review and monitoring assistance to support Japan before, during and after the discharge of treated water, which is expected to start in 2023.

Conditions at the Fukushima Daiichi nuclear power plant site have improved since a review in 2018, the International Atomic Energy Agency (IAEA) has concluded following its fifth review of Japan's plans and activities to decommission the plant. The IAEA team of experts reviewed the current situation at the site and future plans in areas such as the removal of used fuel and the retrieval of fuel debris, radioactive waste, water and site management.

The Japanese government and Tokyo Electric Power Company (Tepco) plan to release treated radioactive water from the Fukushima Daiichi NPP about 1 kilometre off the coast, according to a plan released by Tepco on 25 August. The treated water, containing radioactive tritium, will be released through an undersea tunnel. The government and Tepco concluded that the use of such a tunnel would create less reputational damage than releasing the water directly from the coast near the plant.

Recyclable-Fuel Storage Company Ltd (RFS) now expects its interim used fuel storage facility in Mutsu, Aomori prefecture, to begin operating in fiscal year 2023 (ending March 2024). Following several previous delays, the facility - construction of which began in 2010 - had been scheduled to start up later this year. However, the construction of additional safety measures is taking longer than expected.

Decision follows sanctions over security lapses The Kashiwazaki Kariwa nuclear power station in Japan, where the restart of reactors has bee delayed. Reactors at the Kashiwazaki-Kariwa nuclear power station in Niigata prefecture, western Japan, will not be restarted until fiscal 2022 at the earliest, according to a new business plan submitted to the government by operator Tokyo Electric Power Company.

The plan, which has been revised for the first time since 2017, included an outlook for future revenue and expenditures, assuming that the Kashiwazaki Kariwa-7 reactor would be restarted in October 2022 at the earliest and Kashiwazaki Kariwa-6 in April 2024. It also said that one out of the remaining reactors, Units 1 to 5, would be restarted in 2028.

The revised cost benefit of restarting a reactor was estimated to be about 50 billion yen ($450m) per unit to reflect changes in fuel prices and other factors. This was down from 90 billion yen in the previous plan.

In April, Tepco said it would accept sanctions imposed by regulators over a lack of anti-terrorism measures at Kashiwazaki Kariwa-7, a step that would prevent the restart of the facility for at least a year.

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.
