This final report covers work done concerning the conditioning of alpha- bearing solid incineration wastes. Isostatic pressing parameters are defined using containers 36 mm in diameter; the physicochemical properties of the compacted ashes are determined with 140 mm diameter containers and industrial feasibility is demonstrated with 300 mm diameter container. Two types of ashes are used: ashes fabricated at Marcoule (either in devices developed by the CEA for the MELOX project with a standard MELOX composition, or by direct incineration at COGEMA's UPl plant) and fly ash from a domestic waste incinerator. A major engineering study is also undertaken to compare the three known ash containment processes; isostatic pressing, melting, and cement-resin matrix embedding. The flowsheet, operational chronology and control principles are detailed for each process, and a typical plant layout is defined to allow comparisons of both investment and operating costs.
