Japan’s Rokkasho nuclear reprocessing plant runs into trouble yet again

Nuclear plant operator halts uranium production, https://www3.nhk.or.jp/nhkworld/en/news/20170903_04/, The operator of a uranium enrichment plant in northern Japan has suspended uranium production to see if there are problems with its quality control system.

The plant in Rokkasho Village, Aomori Prefecture, is the only commercial facility in Japan to enrich uranium for nuclear power generation. A division of Japan Nuclear Fuel Limited that operates the plant was ordered to improve its quality control system last year.

It reported to the president that steps were taken, which turned out not to be true.

The Nuclear Regulation Authority then approved measures to prevent similar irregularities. The operator met the government requirements for producing uranium in May.

In one of a series of safety mishaps, a fire started at an emergency power generator. The operator had failed to replace parts for 28 years, more than 10 years longer than recommended by the manufacturer.

Officials at the authority said they wonder if the operator has the ability to determine problems and challenges. Japan Nuclear Fuel decided to take uranium out from enrichment facilities and once again check quality control problems.
