Nevada Nuclear Waste Storage Investigations Project: Final Report of Core Drill Conceptual Design Study for Retrieval of Radioactive Waste Disposed in a Geologic Repository

摘要

The system consists of an out-of-hole drive system with a rotating drill string attached to a core barrel type drill head. This report describes the system's capacity, equipment specifications, operation procedures, manpower and equipment requirements, and capital and operating costs. Although the system is deemed feasible, it is costly, complicated, and labor intensive for general use in retrieval operations. Similar systems may, however, be candidates for use in special situations in which retrieval operations are to be completed under abnormal conditions. 16 figs., 5 tabs. (ERA citation 13:000369)
