One of the methods of radioactive waste management that is receiving considerable attention today is the storage of nuclear waste in geological formations. At present, the geological formation for storage that appears most desirable is the rock salt formation. Although no historical data are available to judge the long-term structural adequacy of such storage in salt, current technology makes it feasible to analyze and design the structure and make reasonable predictions about its performance. It is possible to demonstrate such an analytical technique and to predict the structural behavior of the salt during the operating life of the facility.
