“Practical Elimination on Large Release of Radioactive Materials” and Safety Performance Research on HPR1000

Abstract

Evolution of concept on “practical elimination on possibility elimination on large release of radioactive materials” is summarized systemically in this paper, and then some insights, including the definition of “practical elimination,” the meaning of “large release,” the radioactive materials source and the severe accident condition, should be practically eliminated, and the demonstration method of “practical elimination” is presented. After that, analysis and research on domestic third nuclear power plant HPR1000 are conducted from the perspective of “practical elimination on large release of radioactive materials”; the results indicate that: with completed measures of severe accident prevention and mitigation, HPR1000 has achieved the safety goal of “practical elimination on large release of radioactive materials.”
