Spent Nuclear Fuel issues
The DOE spent nuclear fuel includes both irradiated and unirradi-
ated fuel from various reactors and experiments (including fuel from the
Fast Flux Test Facility reactor), test reactor fuel, Navy fuel, and even
damaged core debris from the Three Mile Island Unit 2 accident. This
study does not consider research needs relating to the disposition of
spent nuclear fuel, although DOE has ownership of substantial amounts
with widely varying characteristics and integrity. These fuels are stored
at H anford, Savan nah River Site, and I N EE L.
A large fraction of DOE's fuel inventory consists of the 2,200 metric
tons of zirconium-clad uranium metal fuel in the two Hanford K-Basins.
Nearly half of this fuel is damaged, some to the point of fine scrap and
sludge. There is an on-going program to collect most of this material in
multi-canister overpacks. The material is then dried and rendered inert
prior to its disposal in the geological repository. However, several tons
of finely divided particulates are slated to be dissolved, added to the
HEW tanks at Hanford, and co-disposed with the HEW.
