Abnormal discharge confirmed in liquid waste treatment system at Wolsong-2 nuclear power plant (South Korea)

Korea Hydro and Nuclear Power's Wolsong Nuclear Power Headquarters said on the 12th, "Around 10:05 a.m. on this day, a low-concentration radioactive material was released from the storage tank of the Wolsong 2 Unit (a 700,000 kW pressurized heavy water reactor) which was in normal operation.
"We confirmed that liquid waste had been discharged without supervision and reported this to the Nuclear Safety Commission's regional office," the company said.
According to the Wolseong Nuclear Power Headquarters, the evaluation results of the radioactive materials released into the ocean were
The amount of hydrogen was confirmed to be 1.116×1010Bq, and the amount of gamma nuclides was confirmed to be 3.589×105Bq. These figures are 1/100,000 (0.001%) of the annual emission limit for tritium, and 1/100,000 (0.001%) of the annual emission limit for gamma nuclides.
The gamma nuclide is said to be at a minute level, equivalent to 6 parts per million (0.0006%). Furthermore, the effective radiation dose to residents from this leak is 6.97 x 10-8 mSv per year, which is less than the normal dose.
The HQ has indicated that it will continue to analyze marine environment samples and monitor the impact on the environment. A HQ official said, "There has been no additional release of liquid radioactive material, and the current level is
The power plant remains in a stable condition, and we will take necessary measures after investigating the detailed cause.
