Operational event at Taishan Nuclear Power Station
**************************************************
On May 27, when a planned operation was conducted at Unit 1 of TNPS to switch the power supply from the auxiliary transformer to the station transformer on the distribution board, a circuit issue prevented the circuit from closing on time, triggering the emergency diesel generator to activate automatically. Station staff immediately carried out an on-site inspection. After confirming that everything was in order, they safely shut down the emergency diesel generator and restored the normal power supply.
Throughout the above event, Unit 1 remained in a safe and stable 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 was classified as a Level 0 deviation on May 27.
