Advanced HLW management strategies employing both synroc and borosilicate glass waste-forms

Recent resurgence of interest in waste partitioning permits the consideration of advanced strategies for Righ-level waste (HLW) management based on exploitation of Synroc in conjunction with borosilicate glass. The synergies resulting from the complementary of these waste-forms and their respective process technologies opens up the opportunity to reduce the overall volume of conditioned HLW for geological disposal. The paper provides a summary of the salient features of Synroc and discusses strategies for the conditioning of partitioned wastes from the reprocessing of UOX and MOX fuels from nuclear power generation. The discussion will also explore potential in U.S. defence waste remediation and disposition of excess fissile materials such as Pu. (authors)
