Thermomechanical evaluations of potential repository horizons
In FY 1979, Sandia National Laboratories started evaluation of the potential of tuff for a nuclear waste repository. At that time, only the Bullfrog Member at Yucca Mountain was being considered as a potential repository horizon. In May, 1981, several potential repository horizons were added. Horizons now being considered at Yucca Mountain, in order of increasing depth, include: (1) the Topopah Springs Member, (2) the Tuffaceous Beds of Calico Hills, (3) the Bullfrog Member of Crater Flat Tuff, and (4) the Tram Member of the Crater Flat Tuff. Three studies underway in FY 1981 initiated work leading to the final rank-ordering of potential repository horizons. In the first study, potential repository hozizons were classified on the basis of available data using the South African Council for Scientific and Industrial Research Geomechanics Calssification System. The second study addresses the effects of dipping beds at Yucca Mountain; and the third study addresses the concern about variation in thermomechanical properties.
