​​The Nuclear Emergency Committee Office of the Guangdong Province notified the Security Bureau of an operational event at Taipingling Nuclear Power Station (TPLNPS), a Security Bureau spokesperson said today (July 30).
 
     Severe Typhoon Noul made landfall at Pinghai Town, Huidong County, Guangdong Province, at 3.50am on July 26, with the landing point approximately 25 kilometres from the TPLNPS. TPLNPS had activated its typhoon emergency response and completed all emergency preparedness measures before the typhoon's landfall. Due to the impact of the severe typhoon, two 500kV transmission lines of the power grid experienced sudden faults and tripped in succession at 4.39am. TPLNPS strictly followed the standardised operating procedures for unit control, and Unit 1 was switched to house-load mode for stable operation. Following emergency repairs, the transmission lines were restored to normal, and Unit 1 was successfully reconnected to the grid at 6.20am. 
 
     During the entire period affected by Typhoon Noul, the Unit of TPLNPS remained in a safe condition, the three safety barriers remained intact, and there was no release of radioactive substances. This deviation did not affect the safety of the Unit, the health of the workers, the nearby public or the environment. In accordance with the International Nuclear and Radiological Event Scale and the relevant nuclear safety regulations, this event falls under the category of "other event" that the operator of TPLNPS considers reportable, and was classified as a Level 0 deviation on July 27.
