At nuclear power reactors around the United States, quantities of spent or
irradiated nuclear fuel are growing while owner-operator companies await th
e approval of a permanent storage facility. Some reactors have run out of s
pace in their cooling pools and have had to resort to dry cask storage. The
first half of this paper looks at the policy history of interim storage in
the United States, discusses the current storage status at individual reac
tors, and then reviews the technologies available to deal with it. The seco
nd half of the paper considers the different options for dealing with this
hazardous material in the interim, before a permanent high-level nuclear wa
ste repository is opened, and examines the safety, security, transportation
, economic, political, and other issues that bear on the choice of option.
