KHNP Hanul Unit 6, Power Generation Resumes

Normal Operation Output Around 9 AM on the 17th

KHNP Hanul Nuclear Power Headquarters (Director Lee Seyong) announced that "Hanul Unit 6 (Pressurized Water Reactor, 1,000 MW class), which was shut down on April 1 due to low steam generator water level, resumed power generation on the 16th and reached normal operating output around 9 a.m. on the 17th."

The cause of the reactor shutdown was confirmed to be damage to the signal line controlling the rotational speed of the main feedwater pump, which resulted in a decreased flow supplied to the steam generator.

The Hanul Nuclear Power Headquarters has completed maintenance of the affected signal line and plans to implement follow-up measures to prevent recurrence, including multiplex design for main feedwater pump speed control.
