Geologic disposal of nuclear waste

The natural and engineered barriers provided by geologic storage of nuclear wastes are the most likely choice of countries looking for a permanent solution. A review of the properties of nuclear wastes and the management strategies that will protect the public and the environment describes the isolation and disposal systems and their geologic requirements. These include a host-rock formation of adequate size, low-water content and movement, known physical and chemical characteristics, and geologic stability. Work in progress at DOE's test and evaluation facility at the Nevada Test Site and in other countries focuses on site selection, cannister design, and procedural requirements. Legal and institutional uncertainties must be resolved in addition to a successful demonstration of technology. 3 figures
