A reactor at the Uljin Nuclear Power Plant in Uljin, North Gyeongsang Province, shut down on Thursday.
State-run operator Korea Hydro & Nuclear Power said a reactor stopped operating at 6:41 p.m. after firing off a warning signal.
Officials said the suspension has nothing to do with a radiation leak, adding that an investigation into the cause was launched immediately after the problem was reported.
The pressurized water reactor has been in operation since 1988.
