Incentives and techniques for increasing the capacity of the geologic repository

PDF Version Also Available for Download.

Description

Estimates of the materials potentially destined for emplacement in Yucca Mountain exceed the statutory repository capacity limit of 70,000 metric tons initial heavy metal. Removal and subsequent burning of the actinides in these materials can dramatically increase the repository capacity, postponing or perhaps eliminating the need for a second repository. The detailed calculations described herein verify portions of a promising actinide removal and waste emplacement concept, HEWEC. Results from heat transfer calculations indicate that more than 2.5 times the material may be emplaced using a combination of optimum geometry and actinide recycle. This optimum geometry includes additional drifts and closer ... continued below

Results from heat transfer calculations indicate that more than 2.5 times the material may be emplaced using a combination of optimum geometry and actinide recycle. This optimum geometry includes additional drifts and closer borehole spacing within the drifts. Future work will quantify the additional benefits that may be derived from drift ventilation and staggered emplacement strategies.
