SUBJECT:
FINAL LIVERM0RE REPORT ON UPDATED SEISMIC HAZARD ESTIMATES FOR EASTERN UNITED STATES NUCLEAR POWER PLANT SITES p
r The enclosed Lawrence Livermore National Laboratory (LLNL) report describes the updated n.athodology for developing probabilistic seismic hazard estimates I
at nuclear power plant sites in the Eastern Unfted States.
LLNL performed a re-elicitation of seismicity and ground motion experts to-improve thei.'
estimates of uncertainty in seismicity parameters and ground motion models.
Using these revised inputs, LLNL updated the seismic hazard estimates r
documented in NUREG/CR-5250 (1989), A NUREG summarizing the 1993 LLNL final report and documenting the 1993 LLNL hazard estimates for the.69 nuclear power plant sites in the Eastern:U.S. is under development.
