From the very early stages of the nuclear waste management<br/>program, salt has been advocated as the most suitable geologic<br/>medium in which to store high-level radioactive wastes (HLW).<br/>The primary reason for this is based on the fact that, relative<br/>to other rock types, salt has a low yield strength with the<br/>result that, at the confining pressures that exist at depths<br/>of a few thousand feet, salt will deform plastically.
