Due to the continual troubles in the work of dismantling the stack at the Fukushima Daiichi Nuclear Power Station, TEPCO will postpone the dismantling completion period until the end of March next year to the beginning of May next year. Reported to the meeting and resumed the dismantling work that had been suspended.
The 120-meter-high stack is polluted with gas containing radioactive materials at the time of the accident, and cracks are also found, TEPCO disassembles to about 60 meters in half to reduce the risk of collapse It is a plan.
A special device was developed and cutting started in August. However, troubles such as blades could not be removed continued, and TEPCO suspended work and reviewed the plan.
As a result, it was difficult to complete the dismantling by the end of March next year, so we decided to extend the completion period to the beginning of May next year and reported it to the Nuclear Regulatory Commission Study Committee on the 16th.
A member of the study group raised a severe point, such as "Cutting is a fairly advanced challenge. Troubles have continued, albeit okay so far," and work carefully on the premise that troubles will occur in the future. There was an opinion that I want you to proceed.
TEPCO has shown measures for improving the cutting method and work procedure, and resumed cutting the stack from the afternoon of the 16th.
