An international team of nuclear safety experts completed an operational safety assessment at a power plant in Japan.
The Operational Safety Review Team (OSART), led by the International Atomic Energy Agency (IAEA), noted in the 14-day review of the Kashiwazaki-Kariwa Nuclear Power Station that there were many good practices in place and made some recommendations. The review began June 29 and focused on safety measures that have to be in place regardless of whether the plant is operating or not.
The assessment covered leadership and management, training, operations, radiation protection, operating experience, emergency preparedness and severe accident management. The team identified good practices, including implementing comprehensive and robust defense measures against severe accidents, carrying out frequent drills in difficult conditions, and establishing thorough control of all combustible materials to minimize fire risk.
Some of the suggestions include integrating systems that gather operating experience, and collecting the information to be used more proactively; accident management guidance that should cover all plant conditions, and fully integrating and documenting the station’s emergency plans in a way that is clear and easy to use.
The team gave a draft of their recommendations to plant operator Tokyo Electric Power Co. The draft will be reviewed by the IAEA and a final report will be delivered within three months to the station and Japan’s Ministry of Economy, Trade and Industry.
