Behavior of spent nuclear fuel in water pool storage

“…The metallurgical condition of the Zircaloy cladding immediately after reactor discharge is useful so that property changes that occurred in-reactor can be separated from those that occurred during pool storage. Since potential degradation mechanisms are expected to occur very slowly under pool storage conditions (Johnson 1977), fuels that have been stored for relatively long periods are needed to identify slow degradation that may be occurring. Other factors-such as burnup, power history, and fuel rod configuration--could influence spent fuel behavior and were considered in selecting fuel rods for the current examinations.…”

“…Several publications address topics related to spent fuel integrity, including the following: Canada (Mayman 1978;Hunt, Wood and Bain 1979;Walker 1979), France (LeFort and Pouit 1978), Germany (Huppert 1978;Huppert and Zimmerman 1977;Peehs, Petri, Fuchs and Schlemmer 1978), Sweden (Vesterlund and Olsson 1978), the United Kingdom (Parker 1978;Warner 1977;Flowers 1977) and the United States (Johnson 1977;Johnson 1978;Johnson 1979;Zima 1979). There is a concensus that nothing in current experience suggests that degradation is occurring on spent fuel cladding from water reactors during storage in water pools.…”
