Risk assessment for subseabed disposal of high level radioactive waste
Conference

OSTI ID:5964805
Feasibility studies for subseabed high-level waste (HLW) disposal required development of new evaluation standards, performance assessment procedures, and models. The steps for the Subseabed Disposal Project (SDP) risk assessment are interactive as the design develops and the models and data base become more complete. The reference system (including transportation, emplacement, the operating repository, and possible abnormal events) is defined. Since no official radiological protection criteria exist for subseabed HLW disposal, evaluation standards are defined. Analytic and compartmental models are developed for sensitivity and repetitive risk analyses. These fast and convenient computer models are verified with numeric programs. Analysis begins with parametric studies to define the senitivity of each input parameter. This is followed by an attenuation factor analysis to define the effectiveness of each component, and the robustness and limitations of the system. Peak individual, time integrated world population, and biota doses are computed using reference parameters.
