Calculations of radiation field arising from heat generating radioactive waste emplaced in ocean sediments

Energy deposition rates from heat generating radioactive wastes emplaced in ocean sediments have been calculated. Two disposal options are considered; a penetrator, in which waste canisters are placed and then dropped into the ocean sediments; and a drilled option in which waste canisters are placed in a bored hole. Energy deposition rates are presented in tabular and graphical form for times between emplacement (50 years cooling) and 1000 years cooling to enable radiolysis rates and hence material corrosion rates to be determined.
