| Popis: | Examinations have been performed to characterize the distribution of core materials and fission products at the damaged Three Mile Island Unit 2 (TMI-2) reactor. The purpose of this paper is to summarize the current status of the core materials and fission product inventory evaluations at TMI-2 and to present results that may affect reactor source them issues. Principal subjects include the relocation of core materials out of the reactor vessel, the formation of complex, core material interaction products. cecium retention in prior molten material, and the retention of tellurium antimony and ruthenium in association with core materials. Material examinations have now been performed on samples from throughout the reactor building and vessel to provide definition to the end core configuration and materials behavior. These examination results have been used to evaluate the redistribution and inventories of core materials and fission products in the damage reactor core for comparison with expected material behavior, particularly for fission products. |
