Abstract
The primary objective of the Synroc strategy for high-level waste (HLW) management is to provide a wasteform which has a much greater resistance to leaching by groundwaters than borosilicate glass and which is capable of maintaining its integrity in suitable geological environments for periods exceeding one million years. A further objective of this strategy is to utilize a waste form, Synroc, which is capable of generating public confidence in its ability to function effectively as an immobilization barrier for very long periods. Section 2 of this chapter deals with the composition and preparation chemistry, mineralogy and microstructure of Synroc-C. Section 3 discusses chemical durability: the effect of fundamental variables and fabrication parameters on leach rates. Section 4 discusses radiation damage in the various mineral components of Synroc-C caused by fast-neutrons, alpha-particles and other fission fragments. Section 5 deals with thermal and mechanical properties. In section 6 the ANSTO/ANU Synroc demonstration plant is described and section 7 is a comparative assessment of Synroc versus borosilicate glass.
