Comparison and discussion of emergency classification on nuclear accident of nuclear fuel cycle facilities in China and USA
The emergency action level of nuclear fuel cycle facilities is one of the grading criteria for the emergency status of nuclear fuel cycle facilities.The grading of emergency status is also an important ba-sis for formulating the level of emergency operations.This paper introduces the history and current situa-tion of the development of emergency classification of nuclear fuel cycle facilities in the U.S.NRC and China.This paper also compares the differences in the emergency status classification of nuclear fuel cy-cle facilities between China and the United States NRC.Finally,analysis results are discussed.It is rec-ommended to conduct a complete secondary PSA study,to provide accident spectrum,and to provide suf-ficient technical support for the development of emergency status classification and emergency action lev-el.
