         There are three Governs~nt-cwied uzanium endtchmont
plants in the United States: at Oax Ridge, Tennessee; seat
Paducah& Kentucky; and neaz Portsmouth. Ohio. These uranium
enrichment plants use gaseous filffusion to enricA the auranim, a
technology the Government has successfully used for 30 year*.
Because the capacity of the three plantr is fully comitted, in
197A Congreas authorized construction of': as add-on to the
Portsnouth diffusion plant. However, :;n 1977, the Preoideat
announced that. instead of tho add-on, the Department of Inergy.
would build an equivalent-sized plant using a tecknology called
gas centrifvge. Findinqs/Conclusions: The a.vantages of
centifnqe technology and the difficulties in otaining
electrical power for a diffusion plant have led to the
conclusion that the economic and technv'.ogical benefits to be
qained by using centri.fuge technology may be wcrth the risk. it
is uncertain, however, whether the project will be completed
within cost and schedule estimates and what role private
industry will assume in the project. There does not appear to be
a clear advantage to building the plant at either Oak Ridge or
Portsmouth. Cost comparisons show a $200 million advantage at
Oak Ridqe. There will be sone disruption associated with a
relocation, and any decision on this matter should consider the
effect any delay would have on the ability to meet enrichment
demand. (RRS)
