Research on Radiation Risk of New Fuel Transportation for HTR-PM
摘要
Abstract
The systemic application of probabilistic safety assessment (PSA ) method to radiation risk assessment of radioactive material transportation was explored ,and then the radiation risk of road transportation of new fuel elements of HTR‐PM was analyzed . Based on actual route data and potential accident scenarios ,both accident conditions of package radiation level hoist and criticality were chosen for accident frequency analysis . The results show that the frequency of package radiation level hoist accident is 4.21 × 10-7 (vehicle · each transportation )-1 , w hile the consequence of criticality accident could not be considered because its frequency is less than 1 × 10-13 (vehicle · each trans‐portation)-1 .T he results of accident consequence show that in the package radiation level hoist accident ,the maximum external exposure dose arising from the accident for emergency worker is 0.55 mSv ,and 4.55 × 10 -3 mSv for public people around ,which are acceptable .The global radiation risk is 1.24 × 10 -10 person · Sv/(vehicle · each transportation) ,for w hich impact accident contributes the maximum percent .关键词
