Krypton-85 is formed in nuclear power reactors and remains trapped until the fuel is reprocessed. Federal regulations limit the release of /sup 85/Kr to the environment, requiring recovery and storage of 85% of the /sup 85/Kr produced in commercial light-water reactors after January 1, 1983. One of the long-term storage options involves encapsulating /sup 85/Kr in zeolites or glasses at high pressure and temperature. This paper presents experimental results for krypton encapsulation and leakage in sodalite, zeolite 5A, and Vycor Thristy glass. The results show that all three materials are feasible for /sup 85/Kr immobilization and long-term storage, although zeolite 5A and Thirsty Vycor are preferable due to lower leakage rates.
