This report on the use of dry-cask-storage technologies at the sites of civilian nuclear power reactors has been prepared by the U.S. Department of Energy (DOE} in response to the requirements of the Nuclear Waste Policy Amendments Act of 1987 (P.L. 100-203). In particular, Section 5064 of the Amendments Act directs the Secretary of Energy to conduct a study and evaluation of using these technologies for the temporary storage of spent nuclear fuel until such time as a permanent geologic repository has been constructed and licensed by the Nuclear Regulatory Commission (NRC). In conducting this study, the DOE is required to consider such factors as costs, effects on human health and the environment, effects on the costs and risks of transporting spent fuel to a Federal facility~ and the extent to which the Nuclear Waste Fund can and should be used to provide funds for at-reactor storage. In addition, the DOE is to consult with the NRC, include the NRC's comments in the report, and solicit the views of State and local governments and the public.
