Effects of spent fuel aging on repository disposal requirements
- Pacific Northwest Lab., Richland, WA (United States)
A study has been carried out to analyze the effects of extended spent fuel aging on spent fuel disposal requirements. The analysis considers additional spent fuel aging up to a maximum of 50 years relative to the currently planned 2010 repository startup. As part of the analysis, an equal energy deposition (EED) methodology was developed for determining allowable waste emplacement densities in a tuff geologic repository as a function of spent fuel age and exposure. The method yields virtually identical results to those obtained by a more indirect method referred to as the {open_quotes}equivalent peak temperature rise concept{close_quotes} that has been used by the Yucca Mountain Project. This study demonstrates how this methodology can be used to design both the waste package and the waste emplacement layout to meet more than one thermal goal simultaneously.
