Abstract
Based on advanced pressurized water reactor nuclear plant,research on severe accident source terms for emergency facility habitability was carried out,including core inventory release,nuclide removal in containment and release pathways to environment.Considering the feature of passive containment cooling system,the prospective failure behaviors for containment were mainly studied,and radiation influences based on containment failure at 24 h and 72 h were estimated.The results show that the radioactive release levels for both conditions reach level 6 of INES (international nuclear and radiological event scale).The radioactive fractions of 133Xe released into environment lie between PWR2-PWR4 of WASH-1400,and the radioactive fractions of 131I released into environment lie between PWR5-PWR6 of WASH-1400.Meanwhile,based on the coastal site in China,operator doses of emergency operation facility (EOF) were assessed,which meet the dose limit value of 100 mSv.关键词
