Study on the dynamic regulation of emission limits of radioactive airborne effluents

According to the national standard GB13695 or operating experience, the regulatory authorities will propose the limit values to manage the normal operation of the nuclear facilities for the effective supervision the operating emissions of the nuclear facilities. Manage limits consist of two components, the normal annual radioactive emissions and possible emissions from expected operating events. With the stable operation and good practices of nuclear facilities, the annual emissions of facilities are well below the limit value. The role of existing management limits in actual operation is not significant. With the safe and stable operation of China's nuclear facilities in the past two decades, it is necessary to optimize the radioactive emission limit value from the perspective of management strategy
