    Theremal profiles for high-level radioactive waste burial
    (Elsevier Science Pub. Co., 1983) Barry, JM; Miskelly, PC; Pollard, JP
    Several solutions for the long-term storage of high-level radioactive waste have been proposed. Essentially they involve the solidification of the spent nuclear material and its storage in the most stable environment possible. The conventional method is to solidify such wastes, by vitrification in borosilicate glass but, at night temperatures and specific hydrothermal conditions, these wasteforms have shown enhanced leachability. This problem can be overcome by reducing the concentration of the heat source (i.e. the radioactive material) but promising alternatives are available, such as the Australian SYNROC process. A computational model for the determination of temperature distribution produced by radioactive decay, particularly the temperature within a cylinder of SYNROC material buried deep beneath the Earth's surface, is discussed.
