Hanul Nuclear Power Plant Unit 6 Reactor 'Abnormal Signal' Automatic Shutdown

[Asia Economy Reporter Dongwoo Lee] Korea Hydro & Nuclear Power Hanul Nuclear Power Headquarters announced that on the 19th at around 12:05 PM, Hanul Nuclear Power Plant Unit 6 (Pressurized Water Reactor type, 100kW class) automatically shut down due to the reactor coolant pump stopping caused by a false signal during the replacement of the PCS card.

The PCS card is a card that transmits signals to the power plant control system, playing a role in sending stop signals to the reactor coolant pump and other equipment in case of abnormal plant conditions or false signals.

KHNP is currently analyzing the cause. However, it is known that there was no external radiation leakage due to this shutdown.
