The Subseabed Disposal Program (SDP) is considering high-level waste (HLW) disposal in the oceanic geologic formations as a possible longer term complement to mined geologic repositories. The approach to safety assessment is to compute occupational exposure for all processes, predict the consequences and probabilities of pre-emplacement accidents and controlled release from the sediments, and analyze of all pathways to man and resulting health effects. Models are being developed to form a physical/mathematical computer description of each process; to measure as well as possible associated phenomena and properties in the laboratory; to make predictions and run confirming in-situ experiments; and to modify predictive methods if required. Models have been developed to describe heat transfer, fluid flow, mechanical response of the sediment, nuclide migration in the sediment, physical and biologic oceanography, land transport accidents, dose to man, and health effects. The largest systems effort in FY-82 has been in the area of sensitivity analyses for the purposes of eliminating unnecessary R and D, quantifying general requirements to obtain specific criteria, defining model requirements, specifying significant variables, defining accuracy requirements for data acquisition, and providing input to the first round of safety assessments scheduled for FY-83.
