This paper presents an overview of potential technologies for stabilization of 238Pu-contaminated waste. Los Alamos National Laboratory (LANL) has processed 238PuO2 fuel into heat sources for space and terrestrial uses for the past several decades. The 88-year half-life of 238Pu and thermal power of approximately 0.6 watts/gram make this isotope ideal for missions requiring many years of dependable service in inaccessible locations. However, the same characteristic which makes 238Pu attractive for heat source applications, the high Curie content (17 Ci/gram versus 0.06 Ci/gram for 239Pu), makes disposal of 238Pu-contaminated waste difficult. Specifically, the thermal load limit on drums destined for transport to the Waste Isolation Pilot Plant (WIPP), 0.23 gram per drum for combustible waste, is impossible to meet for nearly all 238Pu-contaminated glovebox waste. Use of advanced waste treatment technologies including Molten Salt Oxidation (MSO) and aqueous chemical separation will eliminate the combustible matrix from 238Pu-contaminated waste and recover kilogram quantities of 238PuO2 from the waste stream. A conceptual design of these advanced waste treatment technologies will be presented.
