Operational event at Ling Ao Nuclear Power Station
**************************************************
On October 4, Ling Ao Nuclear Power Station Unit 2 was undergoing its planned outage activities. During surveillance, station staff found a deviation in the reading of a water pool level monitoring sensor. The water level of the pool remained normal. Further investigation confirmed that station staff had incorrectly closed a valve for the water level monitoring sensor when preparing a maintenance activity. Immediate rectification was taken to re-open the valve and restore the normal function of the sensor. All operating parameters of the station remained normal throughout the event, which did not have any effect on the staff, the plant or the environment.
The event was classified as a "Below Scale Licensing Operational Event" (i.e. "Level 0" event) on the International Nuclear and Radiological Event Scale, having no effect on the safe operation of the nuclear power station, the health of the workers, the nearby public or the environment. All nuclear generating units at the Daya Bay Nuclear Power Site remain in normal and stable operation.
The DNMC has disclosed the details about this event on its website, which can be viewed at the "operational events" section under the "nuclear and radiation safety information" webpage of the DNMC website.
