**************************************************
An operational event at Ling Ao Nuclear Power Station (LNPS) was reported today (July 2) on the website of Daya Bay Nuclear Power Operations and Management Co Ltd (DNMC), a spokesperson for the Security Bureau said today.
Unit 2 of Ling Ao Nuclear Power Station was undergoing a periodic test of its instrumentation system according to plan yesterday afternoon (July 1). During the test, the power source connected to the testing device produced a small electromagnetic interference to the reactor protection system. The interference triggered an automatic reactor protection signal which led to the safe shutdown of Unit 2. The operators took immediate measures and conducted inspections of the Plant. The reactor was restored to normal working conditions after the satisfactory completion of the said inspections. During the course of the event, all other nuclear generating units at the Daya Bay Nuclear Power Site were in normal and stable operation. The event was classified as a "Below Scale Licensing Operational Event" (i.e. "Level 0" event) on the International Nuclear and Radiological Event Scale of the International Atomic Energy Agency, and had no effect on the safe operation of the nuclear power station, the health of the workers, the nearby public or the environment.
The DNMC disseminates on its website (www.dnmc.com.cn) news pertaining to operation and safety issues of both the Guangdong Nuclear Power Station and LNPS for the information of the general public. Details about this event can be viewed at the "operational events" section under the "nuclear and radiation safety information" webpage of the DNMC website.
