Effect of Near-Field Properties on Dose to Man for a Hypothetical Repository for Intermediate Level Wastes Located at Depth in an Argillaceous Formation

摘要

The degree to which near-field parameters may affect the release of radionuclides from a deep geological repository for intermediate level wastes located in an argillaceous formation is investigated using a sensitivity analysis approach. It is demonstrated that the duration of the physical integrity of waste canisters and vault structure is of little interest, with respect to the groundwater transport pathway. Chemical factors are of more significance and it is not always possible to separate their influence from the effects of geosphere factors. (ERA citation 13:044299)
