PHENOMENOLOGY OF UNDERGROUND NUCLEAR EXPLOSIONS IN ROCK SALT

摘要

Results from investigations of numerous cavities made from underground nuclear explosions conducted in rock salt in the USSR are presented. A physical-chemical model of these nuclear explosions that are based on these investigations has been developed. Problems associated with rock salt evaporation and melting, the cavity temperature regime, progress of rock salt cooling and the distribution of radionuclides in a formed cavity have been described by such model. Scientific problems arising during cavities opening and during preparations for operations have been considered. In addition, problems associated with both radionuclide migration with ground waters and contamination of radioactive products stored in the explosion cavities, are considered.
