Clean salt process final report

“…There are very few regulatory constraints on the reuse of the NaNO, salt. The primary constraint on reuse is the technical feasibility of the reuse options, which was not addressed in this document, but was addressed in a document issued in F Y 1996 (Hendrickson 1996).…”

“…After the report was published, some concern was expressed by stakeholders that use of Na$O, as a back-fill material may not be advisable due to the potential for the carbonate to dissolve in the groundwater, cause leaching of radionuclides from the soil surrounding the tanks, and result in increased rates of transport of the radionuclides to the Columbia River. If the Na2C0, is used as an amendment to a cementitious material that is used as the ballast, as recommended in Hendrickson (1996), then the radionuclide transport issue may be avoided.…”
