There was no wind… but the cutting equipment came off and stopped. Removal of contaminated pipes at TEPCO’s Fukushima Daiichi Nuclear Power Plant

March 1, 2022
On January 1, TEPCO began cutting pipes contaminated with highly radioactive materials between Units 1 and 2 at the Fukushima Daiichi Nuclear Power Plant (Okuma and Futaba, Fukushima Prefecture), but stopped shortly after starting due to a problem with the cutting equipment.

　The site was inaccessible due to high radiation levels, and the work was performed by remote control of a cutting device that was suspended from a large crane. According to TEPCO, around noon on January 1, they began cutting pipes near ground level on the Unit 2 side, but were unable to continue after 15 minutes. A part of a chain-like cutting device called a wire saw came off.
　The work to remove the pipes began on February 24, but the cutting equipment, which had been hung by a crane, was blown away by strong winds, preventing the work from getting underway.
　The pipes are about 30 cm in diameter and measure about 65 meters on the Unit 1 side and about 70 meters on the Unit 2 side. The plan is to cut the pipes into 26 sections, which were used for venting contaminated steam inside the reactor to prevent the containment vessel from rupturing at the time of the accident in March 2011. Remove it.
　Removal of the crane was originally scheduled to begin in October of last year and be completed in March of this year, but has been delayed significantly due to a series of crane failures. (Kenta Onozawa)
