Preliminary evaluation of predicted predicted peark pelease rates from the engineered barrier system for a potential repository at Yucca Mountain, nevada

摘要

Any potential repository for the ultimate didposal of the nation's high-level radioactive wastes is subject to meeting post-closure regulatory requirements as aspecified by the NRC. Three NRC sub-system performance measures are relevant to the evaluation of the Yucca Mountain site and possible engineered barriers. These performance requirements are specified in 10 CFR 60. These include the substantially complete containment requirement, the engineered barrier system (EBS) release requirement, and the pre-waste emplacement ground-water travel time requirement. The present paper documents an initial evaluation of the peak EBS release rates. More detailed disuccsion is presented in M&O (1994)~1.
