EPICOR-II research and disposition program at the INEL

Among the radioactive wastes produced during the cleanup of Unit 2 of the Three Mile Island (TMI) Nuclear Power Station were 50 EPICOR-II liners, used to remove activation products from contaminated water. The EPICOR-II liners are being sent to the Idaho National Engineering Laboratory where they will be stored in special facilities, researched as special wastes, placed in High-Integrity Containers, and disposed offsite at a commercial low-level waste facility. Research efforts include (1) developing a High-Integrity Container, (2) disposing of a liner in a High-Integrity Container on a best-effort basis, (3) examining EPICOR-II liners to determine their integrity, (4) solidifying EPICOR-II resins in cement and synthetic polymer, (5) testing solidified EPICOR-II resins for compressibility and leachability, (6) determining the degradation of EPICOR-II resins, and (7) investigating the behavior of solidified EPICOR-II resin samples in a soil environment (lysimeter test)
