Burial in bedded salt formations has been proposed as a method for permanent storage of solidified high-level radioactive wastes from nuclear reactor fuel preparation and reprocessing and other solid wastes contaminated with transuranium elements. Details of the burial scheme must be such that heat released from the wastes will not adversely affect repository operation, long-term containment integrity, fresh water aquifers, and other nearby sources of minerals. Thermal analysis of a proposed repository has helped to establish the feasibility of the basic con cept and to develop a satisfactory burial scheme that will require ∼600 gross acres (∼1 sq mile) of ground by the year 2000.
