DOE standard guidelines for use of probabilistic seismic hazard curves at Department of Energy sites

摘要

This Standard is intended to provide guidance in the use of the seismic hazard curves developed by the Lawrence Livermore National Laboratory (LLNL) and the Electric Power Research Institute (EPRI). Experience to-date has shown that application of these methodologies can yield significantly different results. In response to this issue, a Seismic Working Group (SWG) has been formed at the Department of Energy (DOE) Headquarters to coordinate the application of these methodologies within DOE in a consistent manner. The position developed by the SWG and contained in this Standard is intended for immediate use in developing seismic hazard estimates at DOE sites for the evaluation of new and existing, nuclear and non-nuclear DOE facilities. This Standard is needed not only to address the LLNL/EPRI issue but also to assure that state-of-the-art seismic hazard methods are incorporated into DOE standards as soon as possible. The DOE is currently involved in a joint program with the Nuclear Regulatory Commission and EPRI to evaluate these existing probabilistic seismic hazard methodologies and to develop recommendations for an improved methodology for the 1990's. The final product of this effort is expected to result in more stable hazard estimates and will supersede this Standard in approximately two years.
