Reference analysis on the utility of engineered barriers for geologic disposal of spent nuclear fuel: overview

Description: The development and characterization of waste forms, containers and other engineered barriers destined for use in the isolation of nuclear waste in deep geologic repositories has progressed to the point where there are several options for barrier systems that are available to help assure safe disposal of nuclear wastes. However, a rigorous basis has not yet developed to define whether various concepts or products are required or desirable, or how effective they should be for how long. This anal… more

Incentives for Partitioning, Revisited

Description: The incentives for separating and eliminating various elements from radioactive waste prior to final geologic disposal were investigated. Exposure pathways to humans were defined, and potential radiation doses to an individual living within the region of influence of the underground storage site were calculated. The assumed radionuclide source was 1/5 of the accumulated high-level waste from the US nuclear power economy through the year 2000. The repository containing the waste was assumed to b… more

A waste package strategy for regulatory compliance

Description: This paper summarizes the strategy given in the Site Characterization Plan for demonstrating compliance with the post closure performance objectives for the waste package and the Engineered Barrier System contained in the Code of Federal Regulations. The strategy consists of the development of a conservative waste package design that will meet the regulatory requirements with sufficient margin for uncertainty using a multi-barrier approach that takes advantage of the unsaturated nature of the Y… more

Reference analysis on the use of engineered barriers for isolation of spent nuclear fuel in granite and basalt

Description: This report evaluates the effectiveness of engineered barriers in delaying or reducing the rate of release of radionuclides from spent fuel in geologic respositories in granite and basalt. It was assumed that the major exposure pathway from the respository to humans would be the ground-water system overlying or underlying a site. Hence, this report focuses on ground-water pathways. A geosphere transport model, GETOUT, and the biosphere transport/dose models, ALLDOS and PABLM, were integrated an… more

Comparison of potential radiological consequences from a spent-fuel repository and natural uranium deposits

Description: A general criterion has been suggested for deep geological repositories containing spent fuel - the repositories should impose no greater radiological risk than due to naturally occurring uranium deposits. The following analysis investigates the rationale of that suggestion and determines whether current expectations of spent-fuel repository performance are consistent with such a criterion. In this study, reference spent-fuel repositories were compared to natural uranium-ore deposits. Compariso… more

Analysis on the use of engineered barriers for geologic isolation of spent fuel in a reference salt site repository

Description: A perspective on the potential durability and effectiveness requirements for the waste form, container and other engineered barriers for geologic disposal of spent nuclear fuel has been developed. This perspective is based on calculated potential doses to individuals who may be exposed to radioactivity released from a repository via a groundwater transport pathway. These potential dose commitments were calculated with an integrated geosphere transport and bioshpere transport model. A sensitivit… more

Survey of radioactive material shipments in the United States

Description: The survey period was from March 1, 1974, through February 28, 1975. Of over 15,000 NRC and Agreement States licensees, and ERDA prime contractors, 2275 received questionnaire packets. Approximately 59 percent of those recipients responded to the survey; of these respondents, 35 percent reported shipping activities. Based on the number of packages shipped annually, the major nuclides were /sup 131/I, /sup 125/I, /sup 99m/Tc, /sup 99/Mo, and /sup 238/U, while those shipped in the greatest amount… more

Incentives for partitioning high-level waste

Description: The incentives for separating and eliminating various elements (but particularly the transuranics) from radioactive waste prior to final geologic storage were investigated. Exposure pathways to man were defined, and potential radiation doses to an individual living within the region of influence of the underground storage site were calculated. The accumulated high-level waste (i.e., the fission product waste produced by reprocessing spent fuel) from the U. S. nuclear power economy through the Y… more
