Japan’s nuclear regulator has resumed its review of an under-construction nuclear fuel reprocessing plant, following a suspension of 8 months because of a maintenance problem discovered last summer. The Nuclear Regulation Authority on Thursday resumed its review of the plant in Rokkasho Village in Aomori Prefecture. The resumption came after the plant’s operator, Japan Nuclear Fuel Limited, gave notice that it has worked out a plan to introduce new safety measures. Last August, rainwater was found to have flowed into a building for emergency power generators at the plant. The rainwater leak was blamed on a failure by the company to conduct mandatory inspections of the area over a period of several years. During Thursday’s review session, Japan Nuclear Fuel explained how it will improve its maintenance programs at the plant. In response, officials from the Regulation Authority said the company should conduct a more rigorous assessment of its past maintenance work. In future review sessions, the regulator is planning to ask about the company’s contingency plans for emergencies such as the fallout of volcanic ash from a nearby volcano, or a plane crash. The company is aiming to complete the construction of the plant in 3 years.
