Abstract: In the nuclear safety evaluation of research reactors,there are differences in the amount and activity concentration of radioactive liquid waste produced by research reactors owing to the variation of their types and operation modes.Moreover,the standards available for research reactors are still lacked and relevant standards on nuclear power plants and nuclear fuel reprocessing plants can only be taken as references.Therefore,the treatment of design safety issues need to be adjusted according to specific facilities.In this paper,the proper safety requirements for research reactor liquid waste storage facilities are proposed by the discussion of several treatments of key safety problems in the evaluation.
