[Asia Economy Reporter Moon Chaeseok] The Nuclear Safety and Security Commission announced on the 26th that it has approved the restart (criticality) of Hanbit Nuclear Power Plant Unit 2, which is undergoing a regular inspection.

The NSSC determined that the reactor operation is possible after inspecting 86 items at the plant since June 3.

During the regular inspection period, three voids were found after cutting the internal containment liner plate (CLP), and the integrity assessment and void repairs were completed.

Following the previous regular inspection, an additional check of the CLP thickness was conducted, but no CLP below the standard thickness (5.4 mm) was found.

In the steam generator heat exchanger tube inspection, tube plugging maintenance was properly performed, and one foreign substance inside the steam generator detected by foreign material inspection equipment was removed.

The NSSC reported that out of 40 follow-up measures to recognize the discharge of contaminated water from Japan's Fukushima nuclear power plant, 36 have been completed and 4 are in progress. Among 16 accident and failure cases in the past three years, 12 have been completed and 4 are ongoing.

The NSSC plans to complete the inspection after conducting nine follow-up tests, including the power increase test.
