摘要

In a previous study it has been shown that alpha -radiolysis of a thin water film on spent fuel stored in copper canister may result in formation of substantial amounts of hydrogen and oxygen. In the present investigation the effect of low LET radiation, such as gamma - and beta -radiations, on these molecules when they diffuse out of the alpha -irradiated layer has been calculated using a computerized radiation chemical program. It has been found that low LET radiation under certain conditions may act as a recombiner for hydrogen and oxygen produced by alpha -radiolysis. The effect of gamma -radiation outside the canister is small - due to the low dose rates prevailing there. However, the relatively high beta -radiation field existing inside the fuel cladding recombines the major part of the hydrogen and oxygen produced by alpha -radiolysis of pure water, in particular if the gases have to diffuse out through bentonite.
