Clinch River

The United States continued fast-breeder reactor research and development with the building of the fast flux test faciHty (FFTF) at Hanford and the SEFOR reactor in Arkansas (59). The next plaimed step was to build a prototype power reactor, the Clinch River fast-breeder plant (CRFBP), which was to be located near Oak Ridge, Teimessee. 

A fairly detailed risk analysis of fires was in the Clinch River Breeder Reactor (CRBR) Risk Assessment Study, 1977. In this study, FMEA was used to identify important fire locations for a wide variety of combustibles, including cables, oil, and sodium. The resulting estimate of the frequency of fire-induced core melt, 5E-7 per reactor-year, is substantially below the estimates discussed above. 

Clinch River Breeder Reactor Project, the first large-scale demonstration breeder reactor is constructed near Oak Ridge, Tennessee. The project died for lack of support, however.

Some previous studies, such as those conducted on the Clinch River, have indicated that biomass may be neglected in a mass balance analysis of radionuclides (I, 4). However, when the biomass was extensive in the flume, a significant portion of the radionuclide was retained, at least temporarily (Figure 4). Plants sorbed radionuclides in the order indicated. 

In 1 979 one of the containment buildings at the Tennessee Clinch River Breeder Reactor project had to be quarantined because of a massive outbreak of Ciyptococcusneoformans. 

This duty cycle creates challenges that have been met by designers of liquid metal reactors that operate at high temperatures, such as the Fast Flux Test Facility and the Clinch River Breeder Reactor Plant. However, this was done at great cost for the analyses, extremely high manufacturing costs, and has created a disconnect between design transients and the real world.

The same day Groves approved a directive that had been languishing on his predecessor s desk throughout the summer for the acquisition of 52,-000 acres of land along the Clinch River in eastern Tennessee. Site X, the Met Lab called it. District Engineer Marshall had thought to wait to buy the land at least until the chain reaction was proved. 

The proposal cleared the Military Policy Committee on Jime 12,1944. On June 18 Groves contracted with the engineering firm of H. K. Ferguson to build a 2,100-column thermal-diffusion plant beside the power plant on the Clinch River in ninety days or less. That extraordinary deadline allowed no time for design. Ferguson would assemble the operation from twenty-one identical copies— Chinese copies, Groves called them—of Philip Abelson s 100-column imit in the Philadelphia Navy Yard. 

Excluding military and space reactors, approximately 20 sodium-cooled fast reactors have been built in a variety of sizes and configurations. These vary from small test reactors to the French Super-Phenix plant, which had an output of 1240 MW(e). In the United States, several fast reactors were built. These included the EBR-II and the Fast-Flux Test Facility (FFTF)—a 400-MW(t) reactor. The Clinch River Breeder Reactor Plant (CRBRP), a commercial demonstration reactor, was designed and partly built before being cancelled. These machines provide a large experience base in refueling operations (Romrell et al., 1989 Althaus and Brahy, 1987).

Eleven miles southwest of Oak Ridge on the Clinch River was the site of the K-25 gaseous diffusion plant upon which so much hope had rested when it was authorized in late 1942. Championed by the British and placed first by the Lewis committee, gaseous diffusion seemed to be based on sound theory but had not yet produced samples of enriched uranium-235. 

Galvanizing has seen common use in the power industry for over 50 years. The galvanized lattice tower or galvanized substation structure has been in use in the United States by the Tennessee Valley Authority since the mid-1930s. At the Clinch River substation, completed in 1936, galvanizing has provided complete corrosion protection of all steel structures. A recent inspection... 

In the early 1980s, the liquid metal fast breeder reactor (LMR) program focused on deployment of the Clinch River Breeder Reactor (CRBR) in Tennessee. The program encountered difficulties because of cost escalations and schedule delays. The LMR program faced challenges because uranium was not becoming scarce and prohibitively expensive as had been predicted earlier.
