Regarding the trouble at the Fukushima Daiichi Nuclear Power Plant where water containing radioactive materials leaked from a contaminated water purification system, the Nuclear Regulation Authority said that within TEPCO, the department responsible for the work that caused the problem was not clear, and management was not working properly. It was pointed out that this was a suspected violation of the ``implementation plan'' that stipulated work rules and safety measures.
On February 7th, there was a problem at the Fukushima Daiichi Nuclear Power Plant where water containing radioactive materials leaked outdoors from a contaminated water purification system, and TEPCO reported the status of the investigation at a meeting of the Nuclear Regulation Authority on the 19th. did.
In response, TEPCO blamed the problem on workers who overlooked that the valves in the pipes inside the equipment were left open while running water through the system, and stated in the procedure manual that the valves were closed. He explained that the problem was that the company did not specify that the user should close the door.
In response, the Nuclear Regulation Authority, which is the secretariat, has established work rules and safety measures, citing that the department responsible for controlling the opening and closing of valves within TEPCO was not clear, and that the status of the valves had not been controlled before work. It pointed out that this was suspected to be a violation of the "implementation plan" and called for thorough measures to prevent it from happening again.
At the Fukushima Daiichi Nuclear Power Plant, there was a problem in October last year when workers cleaning contaminated water treatment equipment were exposed to waste liquid containing radioactive materials, and violations of the "implementation plan" were also pointed out at that time. .
A person in charge of the regulatory agency also called for the system to be strengthened, saying, ``If there is a serious problem, personnel will be busy dealing with it and management will be lax, which could lead to a series of problems.''
