CORROSION MONITORING OF STORAGE BINS
FOR RADIOACTIVE CALCINES
I SUMIARY
The high-level waste at the Idaho Chemical Processing Plant (ICPP)
is generated during the reprocessing of spent nuclear fuel. The fuel
comes from nuclear reactors using highly-enriched uranium-235 fuel. This
waste is primarily the first-cycle raffinate from the solvent extraction of
dissolved fuel solutions, and is self-heating. The second- and third-cycle
solvent extraction wastes are handled as high-level waste also.
Management practice for high-level waste at the ICPP is to store the
liquid waste safely for a period not to exceed five years, calcine the
liquid to a dry solid, and store the solid safely in engineered bins of
Types 405 and 304 (0.06 percent carbon maximum) stainless steels where
it will'be retrievable at all times(1,2). After exposure of specimens in
the radioactive dry solids for periods up to six years, the average-
projected 500-year penetration rates are 20- and 5- mils for Types 405
and 304 stainless steels.
