National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Relative Release Rates of Nitrate, Tc, Cs and Sr from Saltstone.

DE2001783923

Publication Date	2001
Personal Author	Oblath, S. B.
Page Count	16
Abstract	The relative release rates of nitrate, cesium, strontium, and technetium have been measured from saltstone and soilcrete (salt-stone containing soil) under saturated conditions. These are the first measurement of radionuclide release rates from saltstone, and confirm the assumptions used earlier in mathematical modeling. Both saltstone and saltcrete have comparable leach rates for nitrate and pertechnetate anions. Cesium and strontium are more strongly held in both materials, but show differences between the two matrices. These data fully support the assumption that no species leaches more rapidly than nitrate.
