Reprocessing plants Idaho

Calcination of HLLW has been applied as a first step to solidify the wastes from the Idaho reprocessing plant. Since die mid-sixties the waste has been converted to a solid powder vviiich is presently stored in underground vaults [28]. 

U.S. plants. The principal U.S. reprocessing plants are listed in Table 10.3, together with their main process features. All use some form of the Purex process. In 1979, the only ones operating were the Savannah River and Idaho plants of the U.S. Department of Energy (DOE). The Hanford plant had been used primarily for recovery of plutonium and uranium from irradiated natural uranium, but was versatile and had been used, for example, for Thorex...

The Idaho Chemical Processing Plant is a versatile, multipurpose facility used for recovering highly enriched uranium from a variety of fuels in naval propulsion, research, and test reactors. Materials processed [Al] include aluminum-alloyed, zirconium-alloyed, stainless steel-based, and graphite-based fuels. The West Valley plant, although designed primarily for low-enriched uranium fuel from power reactors, also processed plutonium-enriched and thorium-based fuels. It is the only U.S. plant to have reprocessed fuel from commercial nuclear power plants. 

In the reprocessing-of highly enriched uranium at the Idaho Chemical Processing Plant (ICPP) corrosive concentrated uranium solutions are generated from process upsets, custom processing, and sample residues. A study was performed to determine an alteriiatlve critically safe storage c -stem to the one in present use for these solutions, .- ... 

Soluble neutron imisons assure criticality control in two of the head-end foel reprocessing systems at the Idaho Chemical Processing Plant. Soluble poisons have been used successfully since 1964 and will be enqtloyed in the ph>Jected new head-end processes. The use of soluUe poisons (a) greatly increases the process output,... 

Reprocessing of highly enriched irradiated reactor fuel at the Idaho Chemical Processing Plant (ICPP) presents significant problems to the Criticality Safety (CS) and Safeguards Security (S S) Sections. Two major interactions between these sections occur when irradiated fuel is stored and fuel b dissolved.
