Abstract
The radionuclide emission concentration in uranium-containing liquid effluents from uranium conversion and enrichment facilities constitutes a key aspect of nuclear safety supervision for liquid effluents.To gain an in-depth understanding of the monitoring and supervision of uranium-containing wastewater,it is necessary to conduct research and analysis on the radioactive activity concentration limit,uranium concentration limit,and their interrelationships.Starting from the origins of these regulatory limits,this study first analyzes the relevant recommended values of the International Atomic Energy Agency(IAEA),compares them with the regulatory limits of the U.S.Nuclear Regulatory Commission(NRC),and derives conclusions based on China's guiding principles for radiation dose management limits.Finally,it compares the relationship between the currently implemented alpha activity concentration limits and uranium concentration limits for wastewater.Through the above research and analysis,it can be found that China's regulatory requirements for uranium-containing wastewater are consistent with the guiding principles of the IAEA and more stringent than those of the United States.However,there remains an issue of insufficient alignment between China's uranium concentration management limits and alpha activity concentration limits.Therefore,considering the actual supervision practices,it can be concluded that China's regulatory requirements for the discharge of uranium-containing liquid effluents are safe and reliable.This study also identifies the problems and precautions in the supervision of radioactive effluent discharge,and puts forward suggestions for the formulation and revision of relevant standards.关键词
