Risk of decommissioning work Fukushima Daiichi Nuclear Power Station Deteriorating at approximately 10 buildings April 27, 18:09

At the Fukushima Daiichi Nuclear Power Station, where decommissioning work is in progress, approximately 10 buildings, including the Unit 4 reactor building, have undergone significant deterioration due to the effects of the 9-year-old tsunami and hydrogen explosions, and walls and structures due to earthquakes, etc. TEPCO has decided to consider measures because there is a risk that workers may be injured if they fall.

Last year, the Fukushima Daiichi Nuclear Power Plant had a problem of aging equipment, such as the corrosion of iron scaffolding of the exhaust stack, and TEPCO evaluated the degree of deterioration of approximately 580 buildings on the premises of the nuclear power plant27 Reported at the Nuclear Regulatory Commission meeting on Sunday.

As a result, about 10 buildings, including the Unit 4 reactor building and the waste-related building on the south side of the reactor building, have been significantly deteriorated due to the effects of the 9-year-old tsunami and hydrogen explosion.

Regarding this, the Nuclear Regulatory Commission has said that there is a risk in decommissioning work, such as the walls being peeled off due to the shaking of an earthquake and the structures being dropped, which could injure workers.

TEPCO has a policy to clarify measures and the timing of implementation by the end of next month.

In addition, as a result of examining the facilities and equipment on the premises and 340,000 locations, it became clear that there are 36,000 locations where neither equipment nor detectors to prevent leakage of radioactive materials are provided, and countermeasures are taken. I will consider it.
