Regulatory Commission visits Fukushima Daiichi Nuclear Power Plant over exhaust filter damage

Oct.28, 2021
On October 28, members of the Nuclear Regulation Authority (NRA) visited the Fukushima Daiichi Nuclear Power Plant and inspected the facilities where the problem was found, following a series of damages to the exhaust filters of the facilities that treat contaminated water at the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company.

In September of this year at the Fukushima Daiichi Nuclear Power Plant, 32 of the 76 exhaust filters attached to the storage containers for radioactive waste from the ALPS system, which treats contaminated water, were found to be damaged.

The same exhaust filters were found to be damaged two years ago, but TEPCO replaced the filters and continued to operate the plant without analyzing the cause or taking countermeasures.

In response to these problems, Tomo Tanaka, Nobuhiko Ban, and other members of the Nuclear Regulation Authority inspected the Fukushima Daiichi Nuclear Power Plant on March 28.

Guided by TEPCO officials, the commission members entered the facility where the problematic exhaust filter was installed and confirmed the conditions at the time.

The Nuclear Regulation Authority (NRA) believes that there was a problem with TEPCO’s management system and will investigate in detail the cause and background of the repeated damage.

Also, on the 29th, they plan to check the temporary storage area for radioactive waste generated from decommissioning of the plant in response to the rapid increase in temporary storage of radioactive waste outside.
