Abstract:
An envelope accident was selected and corresponding source term was given. Then this paper made a calculation about the size of emergency planning zone. Calculation results show that the radioactive release of CUP600 to the environment is small, the effective dose and thyroid dose during the whole accident are both less than the general optimized intervention level. The plum emergency zone can be totally inside the site boundary, so technically, out site plum emergency planning zone can be eliminated.
