Description
Mechanical strength, volatility and leach resistance tests have been conducted on ten representative alternative waste form materials. Glass PNL 76-68, celsian glass ceramic, and SPC-5B supercalcine waste forms ranked the highest in overall performance while the 100% PW-9 calcine forms had the least desirable properties. Glass PNL 76-68 had the highest mechanical strength, measured by diametral compression; both glass PNL 76-68 and SPC-5B supercalcine have volatile losses less than 3 x 10-2 mg/mm2 at temperatures below 11000C. These two waste forms also provided the best overall leach resistance. Processing techniques such as hot pressing or hot isostatic pressing did not produce a significantly better product over conventional cold press and sintering techniques for SPC-5B supercalcine or PW-9 calcine.
