Preliminary technical constraints for a repository in tuff
The Nevada Nuclear Waste Storage Investigations (NNWSI) project has established preliminary technical constraints for a repository in tuff. The purpose of the technical constraints is to provide quantitative limits against which to assess the performance of a repository during the different phases of its existence. The constraints should also provide a link between individual repository component function and specifications to be used for conceptual and final repository design. The study focused on the very-near, near, and far field repository domains and time intervals of 0 to 110 years (operational period), 111 to 1000 years (containment period), and greater than 1000 years (isolation period). To date, only mined geologic disposal in tuff has been studied with emplacement of waste packages in vertical boreholes located in the floors of disposal rooms. A repository has been considered located in both saturated (below the static water level) and unsaturated (above the static water level) rock and waste packages with and without a backfill and containing spent fuel or reprocessed commercial high-level waste (borosilicate glass). Accidental or extraordinary events in the repository were not considered nor did we attempt to establish economic constraints.
