Forced Ventilation Analysis of a Commercial High-Level Nuclear Waste Repository in Tuff. Topical Report RSI-0175

摘要

This report addresses the feasibility of using blast cooling for rapid drift and formation cooling prior to a nuclear waste retrieval operation. A coupled conduction/convection analysis is used to examine the various parameters and conditions which control the blast cooling process for the purpose of assessing their relative significance and potential impact on developing a blast cooling scenario for a nuclear waste repository in tuff. Formation stability is addressed briefly with regard to the potential for thermal spalling induced by the rapid cooling of the heated repository walls. (ERA citation 08:043382)
