Book Lawrence Livermore National Laboratory Site Seismic Safety Program

Download or read book Lawrence Livermore National Laboratory Site Seismic Safety Program written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lawrence Livermore National Laboratory (LLNL) Site Seismic Safety Program was conceived in 1979 during the preparation of the site Draft Environmental Impact Statement. The impetus for the program came from the development of new methodologies and geologic data that affect assessments of geologic hazards at the LLNL site; it was designed to develop a new assessment of the seismic hazard to the LLNL site and LLNL employees. Secondarily, the program was also intended to provide the technical information needed to make ongoing decisions about design criteria for future construction at LLNL and about the adequacy of existing facilities. This assessment was intended to be of the highest technical quality and to make use of the most recent and accepted hazard assessment methodologies. The basic purposes and objectives of the current revision are similar to those of the previous studies. Although all the data and experience assembled in the previous studies were utilized to their fullest, the large quantity of new information and new methodologies led to the formation of a new team that includes LLNL staff and outside consultants from academia and private consulting firms. A peer-review panel composed of individuals from academia (A. Cornell, Stanford University), the Department of Energy (DOE; Jeff Kimball), and consulting (Kevin Coppersmith), provided review and guidance. This panel was involved from the beginning of the project in a ''participatory'' type of review. The Senior Seismic Hazard Analysis Committee (SSHAC, a committee sponsored by the U.S. Nuclear Regulatory Commission, DOE, and the Electric Power Research Institute) strongly recommends the use of participatory reviews, in which the reviewers follow the progress of a project from the beginning, rather than waiting until the end to provide comments (Budnitz et al., 1997). Following the requirements for probabilistic seismic hazard analysis (PSHA) stipulated in the DOE standard DOE-STD-1023-95, a special effort was made to identify and quantify all types of uncertainties. The final seismic hazard estimates were de-aggregated to determine the contribution of all the seismic sources as well as the relative contributions of potential future earthquakes in terms of their magnitudes and distances from the site. It was found that, in agreement with previous studies, the Greenville Fault system contributes the most to the estimate of the seismic hazard expressed in terms of the probability of exceedance of the peak ground acceleration (PGA) at the center of the LLNL site (i.e., at high frequencies). It is followed closely by the Calaveras and Corral Hollow faults. The Mount Diablo thrust and the Springtown and Livermore faults were not considered in the hazard calculations in the 1991 study. In this study they contributed together approximately as much as the Greenville fault. At lower frequencies, more distant faults such as the Hayward and San Andreas faults begin to appear as substantial contributors to the total hazard. The results of this revision are presented in Figures 1 and 2. Figure 1 shows the estimated mean hazard curve in terms of the annual probability of exceedance of the peak ground acceleration (average of the two horizontal orthogonal components) at the LLNL site, assuming that the local site conditions are similar to those of a generic soil. Figure 2 shows the results in terms of the uniform hazard spectra (pseudo-spectral accelerations for 5% damping) for five return periods. Although this latest revision is based on a completely independent and in many respects very different set of data and methodology from the previous one, it gives essentially the same results for the prediction of the peak ground acceleration (PGA), albeit with a reduced uncertainty. The Greenville fault being a dominant contributor to the hazard, a field investigation was performed to better characterize the probability distribution of the rate of slip on the fault. Samples were collected from a trench located on the northern segment of the Greenville fault, and are in the process of being dated at the LLNL Center for Acceleration Mass Spectrometry (CAMS) using carbon-14. Preliminary results from the dating corroborate the range of values used in the hazard calculations. A final update after completion and qualification (quality assurance) of the date measurements, in the near future, will finalize the distribution of this important parameter, probably using Bayesian updating.

Book Lawrence Livermore National Laboratory Site Specific Standard for Nonnuclear Safety Analysis

Download or read book Lawrence Livermore National Laboratory Site Specific Standard for Nonnuclear Safety Analysis written by and published by . This book was released on 2003 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lawrence Livermore National Laboratory (LLNL) and the NNSA Livermore Site Office teamed up to prepare a site specific work smart standard setting requirements for preparation of safety basis documents for LLNL non-nuclear operations and facilities. This standard documents how all hazards (biological, chemical, explosive, industrial, and radiological) shall be evaluated, classified, analyzed, and controls developed. This standard was developed to evaluate hazards at the facility level to mesh with LLNL's ISM system for reviewing hazards at the activity level. This standard presents an approach to establishing safety basis for non-nuclear operations and activities, taking a graded approach based on the potential for impacts to the health of collocated workers and the public. Direct worker safety is covered by LLNL's work activity level reviews and requirements. This standard includes streamlined mechanisms for classifying hazards based upon the unmitigated potential for human health impacts. A review or practices at several private industries, government laboratories, and DOE complex sites provided a benchmark and comparison of safety analysis processes. These approaches were compared with LLNL's existing systems, leading to a determination that facility specific safety basis documents added value to a rapid authorization for new work activities in LLNL facilities. A process for hazard classification that would be viewed as more credible than the previous facility classification system was developed, including a method allowing correlation of chemical inventories with TEEL* concentrations. A graded approach for classification of explosive hazards, consistent with the DOE Explosive Safety Manual, was included. The standard was designed to be complementary with LLNL's existing work smart standards covering the hazards identified in a facility. A standard for LLNL's Work Smart Standard set was prepared that will assure all hazards are covered with appropriate levels of analysis to provide a safety basis for non-nuclear facilities and operations. Other sites may find the overall approach a credible mechanism with a graded approach to classification and hazard and accident analysis to provide a safety basis for non-nuclear facilities and operations.

Book Safety Analysis Report for the Heavy Element Facility Building 251 Lawrence Livermore National Laboratory

Download or read book Safety Analysis Report for the Heavy Element Facility Building 251 Lawrence Livermore National Laboratory written by and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive safety analysis was performed on the Lawrence Livermore National Laboratory's Heavy Element Facility, Building 251. The purpose of the analysis was to evaluate the building and its operations in order to inform LLNL and the Department of Energy of the risks they assume at Building 251. This was done by examining all of the energy sources and matching them with the physical and administrative barriers that control, prevent, or mitigate their hazards. Risk was evaluated for each source under both normal and catastrophic circumstances such as fire, flood, high wind, lighting, earthquake, and criticality. No significant safety deficiencies were found; it is concluded that the operation of the facility presents no unacceptable risk.
