Probabilistic seismic risk at Yucca Mountain from published data

Published data concerning earthquake recurrence, faults and their seismic potential in the Yucca Mountain area, were used as input to a revised Lawrence Livermore National Laboratory/Nuclear Regulatory Commission probabilistic seismic hazard analysis computer code. The unmodified code was used for the eastern U.S. seismic hazard characterization project. Calculations were made to test our revisions to permit western U.S. hazard analyses. Code capabilities were extended to provide a means of testing the effects of revised inputs or alternative expert opinions, (indicative of uncertainty), on seismic and fault displacement hazards. Such revisions or alternative opinions would be expected to arise during the licensing process for a potential U.S. high level radioactive waste repository site at Yucca Mountain, Nevada. The revised code functions properly. This analysis produced results comparable to those previously published
