Advances in Synroc Development

Abstract

Most of the early development of the Synroc wasteform and process technologies focused on the Synroc-C formulation for immobilizing liquid HLW from the reprocessing of commercial LWR spent fuel. This paper first summarizes the main results on Synroc-C and then describes recent advances in the optimization of Synroc formulations and fabrication for use in partitioning/conditioning strategies, immobilization of surplus weapons-useable plutonium, and the treatment of ANSTO wastes
