Disposal of high activity power reactor wastes in salt mines: Mine renovations required for project Salt Vault

Abstract Project Salt Vault is a field-scale demonstration of the disposal of high-level radioactive wastes in a salt mine. Preparations required for the experiment included construction of a new headframe for the main mine shaft. renovation of the existing surface and underground facilities. mining of about 19000 tons of salt to prepare the experimental area. and drilling of a 19.1-in. i.d. waste-charging shaft from the surface to the mine level. 1000 ft below.
