Japanese media: Fukushima's nuclear fuel fragments will be postponed, which will be postponed, which will be postponed in the second degree

The Japanese government and Tokyo Electric Power Corporation (Dongdian) recently announced that it will abandon the outbuilding operation of the Fit 2 of the Fukushima First Nuclear Power Station in Unit 2 Fukushima Power Station.

According to a report from the Kyodo News Agency on August 25, in order to improve security and reliability, Dongdian will increase the preparation time of about one and a half years, and strive to launch the second half of 2023. This will be the second extension of related work, which is delayed by about 2 years from the original plan that was originally scheduled to start in 2021.

Ono, the highest person in charge of the reactor of Dongdian Fugui Power Station reactor, said at a press conference that the extension was due to the need to improve the robotic arm used to take out the operation and the related equipment needed to be transformed. The above -mentioned robotic arms are conducting action tests in Takashi -cho, Fukushima Prefecture. The components of the robotic arm, and the components of the fuel fragments recycling device of the robotic arm are found to be improved in some places. When preparing the fuel fragments, the closed equipment that prevent radioactive material leakage is still damaged.

The report pointed out that the fuel fragmentation caused by the accident is the biggest difficulty in the scrap operation of the first nuclear power plant. Although the Japanese government and Dongdian will maintain the goal of completing the scrap of reactor from 2041 to 2051, other major projects such as lack of fuel will also be postponed. Whether it can be implemented according to the goals is not transparent. For the overall process of ending reactor scrap work from 2041 to 2051, Ono emphasized that the extension of "will not have an impact."

It is reported that there are about 880 tons of fuel fragments in units 1 to 3 of the pile of core melting. Dongdian will take out the fuel fragments from Unit 2 of related work. According to the plan, the robotic arm of about 22 meters in length will be placed in the reactor safety shell, collecting fuel fragments at the bottom of the safety shell, first test a small amount of trials, and then gradually expand the scale.
