Fukushima Daiichi Nuclear Power Plant Decommissioning of the top of the stack ends one month later September 2 15:17
During the dismantling work of the 120-meter-high stack at the Fukushima Daiichi Nuclear Power Station, the cutting and suspension of the highest part was completed about a month later than scheduled, and the video was released. TEPCO wants to finish the dismantling work within the current fiscal year by verifying the issues raised so far and improving the construction method.
The exhaust stack is located next to the reactor buildings of Fukushima Daiichi Units 1 and 2, and in the event of an accident, the gas containing radioactive materials is released and the interior is polluted. Cracks are found in the supporting steel frame.
TEPCO plans to dismantle it to about half the height in order to reduce the risk of the exhaust stack collapsing, but the start was delayed due to insufficient crane height for the work.
Also, after the work started on August 1, troubles such as a malfunction of the device that cuts the exhaust stack were interrupted one after another, and the highest part that was originally scheduled to end in the first two days was suspended and suspended. The work was finally completed on the 1st, a month later.
In the released video, you can see how the uppermost part of the cut stack is slowly lowered onto the ground together with the cutting device by a large crane.
TEPCO has decided to complete the dismantling work within the current fiscal year, and said, “We want to verify the problems of the work that has been done so far and improve the way we proceed with the construction.”
