Operational event at Yangjiang Nuclear Power Station
     An operational event at Yangjiang Nuclear Power Station (YNPS) was reported on the website of Yangjiang Nuclear Power Co Ltd (YNPC), a Security Bureau spokesperson said today (June 2).

     On May 30, Unit 3 of YNPS was in a normal operating condition. After Station staff had completed the equipment maintenance work of the gaseous waste treatment system at the auxiliary plant as planned, minor internal leakage was found at one of the isolation valves of a storage decay tank, resulting in the release of a minute amount of gaseous waste. Station staff took timely action to isolate the valve concerned and conducted repair work in accordance with relevant procedures. The amount of gaseous waste released had not reached the alarm level of the plant radiation monitoring system, and had no impact on the surrounding environment. The unit remained in a safe condition throughout the event. YNPC reported the situation to the relevant nuclear safety regulatory authorities in a timely manner.
     In accordance with the International Nuclear and Radiological Event Scale and the relevant nuclear safety regulations, the event was classified on June 1 as a Level 0 deviation. It had no effect on the safe operation of the nuclear power station, the health of the workers, the nearby public or the environment.
     YNPC has disclosed the details of this event on its website. They can be viewed in the "operational events" section under the "nuclear and radiation safety information" webpage of the website (www.yjnp.com.cn) (Chinese only).
