Radioactive Waste Repository Project: Technical Status Report For Period Ending September 30, 1971

Salt deposits are considered to be most attractive for this purpose because of their wide distribution and great abundance; they are easily mined, have good thermal properties, and are free of circulating groundwater. Other possibilities that have been studied or seriously considered either require excessive surveillance, are more costly, or are more limited in their applicability.<br/><br/>The selection of the Lyons site was based primarily on a consideration of the favorable depth, thickness, and extent of the salt there; the amount of information available concerning key aspects of the site; the availability of the existing mine; and the generally favorable reception expected from the local inhabitants. Since the announcement of this site&#39;s tentative selection, we have completed a conceptual design of the Repository and initiated an investigative program designed to provide positive assurance of the Repository&#39;s safety and feasibility.<br/>
