Krypton-85 Disposal Program Conceptual Design Phase: Final Report

摘要

The conceptual design phase of the Krypton-85 disposal program began with the selection of the dry well concept for both central and reprocessing site disposal. Under the constraints that the repositories must be able to accept either gaseous and zeolite or sputtered metal solid waste forms with same handling equipment, conceptual designs were completed for each of the two repositories and for solid and gaseous waste canisters. Sensitivity and optimization computer codes defined the most cost-effective repository layout, canister loading, and solid waste form characteristics. A preliminary economic analysis was made on the waste processing/disposal system. Several alternative disposal methods were investigated, including seabed, grouted hydraulic fractures, and porous lenses. Research was conducted on glass liners to protect gas bottles from the rubidium decay product. Soils from three potential disposal sites were characterized, and exterior canister corrosion tests were conducted. A geologic gas flow test system was developed to evaluate repository sites. All studies indicated that it should be technically feasible to dispose of Krypton-85 in shallow geologic repositories. (ERA citation 07:042581)
