Title: Literature Review of the Effects of Tetraphenylborate on Saltstone Grout: Benzene Evolution and TCLP Performance

Abstract

As part of the program to disposition the tetraphenylborate (TPB) in Tank 48H and return the tank to service, Salt Processing Development requested a review of the literature to assess the state of knowledge pertaining to incorporation of tetraphenylborate slurries in saltstone grout with respect to benzene generation rates and leaching performance. Examination of past studies conducted at Savannah River Site (SRS) on the incorporation of TPB slurries in saltstone provides a basis for developing a more focused scope of experimental studies. Tank 48H currently contains potassium and cesium tetraphenylborate salts as a result of a demonstration of the In Tank Precipitation (ITP) process in 1983 and subsequent ITPradioactive start-up operations in 1995. The tank currently contains approximately 240,000 gallons of salt solution with approximately 19,000 kg of potassium and cesium tetraphenylborate salts. The presence of the TPB salts makes the waste incompatible with existing High Level Waste treatment facilities. The TPB salts in Tank 48H must be treated or removed to meet the scheduled return to service date of 2007. The two preferred options for disposition of the TBP slurries in Tank 48H include: (1) Aggregation of the material with the Defense Waste Processing Facility (DWPF) recycle stream andmore » disposal in the Saltstone Processing Facility (SPF), and (2) In-Situ Thermal Decomposition using heat in combination with pH reduction and catalyst addition. The current literature review along with the current experimental studies provide a basis for determining the feasibility of the option to incorporate the TPB slurries into saltstone grout.« less
