Radwaste Self-Disposal in Geological Formations by Direct gamma-Ray Heating of Rock

摘要

The mechanism of direct heating of rock by radiation in order to transfer energy to the surrounding rock in penetration setups that use the heat released in radioactive decay is examined. The spatial distribution of the energy release owing to absorption of Co-60 gamma rays in a layer of soil, salt, and ice is obtained. The temperature distribution and penetration rate are estimated for a Co-60 based setup.
