[Asia Economy Reporter Moon Chaeseok] The Nuclear Safety and Security Commission announced that Korea Hydro & Nuclear Power Hanul Nuclear Power Headquarters manually shut down the turbine of Hanul Nuclear Power Plant Unit 2 (a 950 MW pressurized water reactor) at around 5:44 a.m. on the 4th.

The Hanul Headquarters explained that the turbine was stopped due to a deterioration in the water quality of the secondary side feedwater system.

The reactor output dropped to about 1%. There was no external radiation leakage caused by the turbine shutdown.

The turbine generator connected to the turbine is a device that generates electricity by receiving steam produced from the steam generator.

The steam used here is cooled through a condenser and reused, so it does not escape outside.

The NSSC stated that at around 4:36 a.m. on the same day, they received a report from KHNP that the output of Hanul Unit 2 had been reduced and are currently investigating the cause.

An NSSC official said, "The local field office is assessing the initial situation," and added, "An incident investigation team composed of experts from the Korea Institute of Nuclear Safety (KINS) has been dispatched to investigate the detailed cause."

He continued, "Currently, the power plant is maintaining a safe state with a reactor output of 1.2%," and "It has been confirmed that the radiation levels inside the facility are also maintained at normal levels."

The NSSC plans to thoroughly investigate the cause of the incident and continuously monitor KHNP's corrective actions and operational status.
