Radioactivity analysis of the advanced voloxidation process
- 1. Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)
Description
KAERI has been developing an advanced voloxidation process as a head-end process of pyroprocessing technology with INL(Idaho National Laboratory). In this study, we investigated how much a radioactivity level can be reduced by this advanced voloxidation process. Radioactivity analysis was carried out for spent PWR fuels with a burn-up of 45,000 MWD/MTU and an initial enrichment of 4.5%. The radioactivity reduction ratio of the spent PWR fuel meat after the advanced voloxidation process was 41% in the case of a 5 year cooling. It increases with the cooling time from 27% (1 year cooling) to 46% (20 years cooling). This study also present the element and radioactivity distributions of nuclides in fresh spent PWR fuels, those after the advanced voloxidation process, and those of the gaseous fission products released from the advanced voloxidation process
