Abnormal Discharge of 29 Tons of Radioactive Waste from Wolsong Unit 2... Nuclear Safety and Security Commission Launches Investigation

The Nuclear Safety and Security Commission (NSSC) announced that at around 10:23 a.m. on the 12th, it received a report from Korea Hydro & Nuclear Power (KHNP) stating that liquid radioactive waste was discharged into the ocean from the Wolseong Unit 2 nuclear power plant.

According to the NSSC, KHNP discovered that the valve at the tank outlet was open during the sample analysis process, which must be completed before discharging liquid waste into the ocean. KHNP immediately closed the valve to stop the leakage.

Subsequent analysis of the remaining sample in the tank showed that the concentration and estimated discharged radioactivity were at normal discharge levels, the NSSC reported. The amount of radioactive discharge is estimated to be about 29 tons.

Immediately after the KHNP report, the NSSC dispatched experts from the Korea Institute of Nuclear Safety (KINS) to investigate the exact leakage amount and cause. They also plan to collect seawater near the nuclear power plant to conduct a detailed assessment of environmental impact.

The NSSC will investigate and disclose the specific environmental impact assessment results and the appropriateness of safety measures.
