TEPCO postponed the completion of the dismantling of the 120-meter-high stack at the Fukushima Daiichi Nuclear Power Station, which was supposed to be completed by the end of March next year. Around early May next year We have established a policy. TEPCO will report to the Nuclear Regulatory Commission and aim to resume cutting this month.

At the time of the accident, the exhaust stack shared by Unit 1 and Unit 2 at the Fukushima Daiichi Nuclear Power Plant was released, causing gas containing radioactive materials to be polluted and the interior to be contaminated.

TEPCO plans to dismantle and lower it to around 60 meters in order to reduce the risk that this stack, which is 120 meters high, will collapse.

For this reason, we developed a special cutting device that can be operated remotely, and started cutting in August. However, the blades were worn quickly and could not be removed. Is about 9 meters.

As a result of discontinuing the work and reviewing the plan, TEPCO determined that it would be difficult to complete the remaining dismantling by the end of March next year, extending the completion time by more than a month and starting around early May next year The policy has been solidified.

However, depending on the weather and the level of proficiency in the work, the completion time may vary.

TEPCO plans to summarize cutting methods and work procedure improvements and report them to the Nuclear Regulatory Commission meeting. If it is ready, it intends to resume cutting this month.
