Radioactive effluents are gaseous and liquid radioactive materials discharged from nuclearfacilities to the environment. Radioactive effluents discharged from Korean nuclear power plants aremonitored by three criteria: the annual radiation dose to members of the public due to radioactiveeffluents, the concentration of radioactive effluents, and the total amount of radioactivity for radioactiveeffluents. In terms of radiation dose to members of the public living around Korean nuclear power plants,the Nuclear Safety and Security Commission Notice No. 2019-10 stipulates environmental hazardsprevention provisions. In Korean nuclear power plants, these dose standards essentially play the roleof dose constraints for the public. Nuclear power plants control radioactive effluents discharged tothe environment not to exceed these dose standards. The emission control limit is applied to controlradioactive effluents in terms of the concentration of radioactive materials. The emission control limitis the derived radionuclide concentrations which, if inhaled or ingested continuously over a year by amember of the public, would give an individual an effective dose to the annual dose limit (1 mSv y-1). Korean pressurized heavy water reactors apply the total amount of radioactive effluents as a monitoringcriterion. The derived release limit is the derived radioactivity that would cause a public member to havean effective dose equal to the annual dose limit by discharging radioactive effluents to the environment. In 2017, the Nuclear Safety and Security Commission Notice No. 2017-4 was also announced toprovide guidelines for a discharge plan, including the total amount of radioactivity for liquid and gasradioactive effluents discharged by the routine operation of nuclear power plants. Korean nuclear powerplants comply with all the regulations of radioactive effluents, including radiation dose, radioactiveconcentration, and radioactivity, to achieve radiation protection for members of the public.
