Title: Waste package materials screening and selection

Abstract

The two primary waste package barriers (other than the waste form itself) are the corrosion-resistant/structural component and the emplacement hole backfill. While the waste forms proposed for the NWTS program are currently projected to be borosilicate glass and spent fuel, the number of candidate materials for the other barriers is potentially quite large and must therefore be reduced. This is being accomplished through materials screening test programs. The major NWTS programs for the development and testing of corrosion-resistant/structural components and emplacement hole backfills have been performed by Sandia National Laboratories (SNL) for salt media and by Pacific Northwest Laboratory (PNL) for basalt and salt. Materials studies in support of tuff or granite repositories using specific ground waters have not yet been initiated. However, it is expected that the range of ground-water compositions characteristic of salt, sea water, basalt, and de-ionized waters used in the current studies adequately bracket the ground-water compositions for tuff and granite at least for screening purposes. In both the SNL and PNL programs initial candidate materials were selected on the basis of literature surveys and consultations with investigators in the US and abroad.
