Saeul Unit 3 Automatically Stops During 80% Power Test Run... NSSC Launches Investigation

The Nuclear Safety and Security Commission (NSSC) has launched an investigation after Saeul Nuclear Power Plant Unit 3 in Ulju-gun, Ulsan, which is preparing for commercial operation this year, automatically stopped during a test run.

The NSSC announced that it received a report from Korea Hydro & Nuclear Power (KHNP) stating that the reactor of Saeul Unit 3 shut down at around 8:56 p.m. yesterday (August 11).

Saeul Unit 3 has been conducting power ascension tests since receiving operational approval from the NSSC in December of last year.

KHNP reported that the reactor automatically stopped during a trial test designed to cut off power transmission at 80% reactor power.

Saeul Unit 3 is currently maintaining a safe shutdown state, and no radiation-related anomalies have been found.

The NSSC stated that it is currently inspecting safety at the Saeul Nuclear Power Plant Regional Office and plans to dispatch an investigation team composed of experts from the Korea Institute of Nuclear Safety (KINS) to the site to determine the cause of the incident and verify facility safety.
