Response to Questions Clarifying a Previous GAO Report on the Department of Energy's Breeder Reactor Program

GAO was requested to respond to questions clarifying the information contained in a prior report about the Department of Energy's (DOE) breeder reactor program. The information requested included: (1) the best available estimate by GAO of the cost of construction of the Clinch River liquid metal fast breeder reactor (LMFBR) after adjusting for inflation and cost overruns; (2) alternative strategies open to Congress if it wants to maintain a breeder program; (3) the specific electricity demand assumptions used in the GAO estimates; (4) the French experience with its own breeder program with regard to cost overruns, revised estimates of the capital cost of light-water reactors, and revised estimates of the cost per kilowatt-hour of breeder-produced electricity; (5) considerations given, on a cost-benefit basis, to alternative technologies that could meet future demand for electricity and the need for oil displacement; (6) effect certain improvements in nonbreeder reactors would have in extending uranium resources; and (7) a symmetrical comparison to compare the most recent projections with those made at the inception of the Clinch River project.
