Seismic Safety Margins Research Program: Phase II program plan (FY 83-FY 84)

Description: The Seismic Safety Margins Research Program (SSMRP) is an NRC-funded, multiyear program conducted by Lawrence Livermore National Laboratory (LLNL). Its goal is to develop a complete, fully coupled analysis procedure (including methods and computer codes) for estimating the risk of an earthquake-caused radioactive release from a commercial nuclear power plant. The analysis procedure is based upon a state-of-the-art evaluation of the current seismic analysis and design process and explicitly incl… more

Seismic performance of underground facilities

Description: A workshop was held in Augusta, GA, February 11-13, 1981 to review and assess the state-of-the-art for determining and predicting earthquake damage to underground facilities. The papers presented related to data collection and analysis, modeling, and repository design. Discussion groups addressed seismology, rock mechanics and hydrology, modeling, design, and licensing, siting, and tectonics. Most scientists in attendance believed that enough was known to proceed with site selection, design, an… more

Rock failure during massive hydraulic stimulation of the Baca location geothermal reservoir

Description: The analyses of microearthquake signals occurring during hydraulic stimulation provide an estimate of the size and location of the fractures thus produced. Studies of microearthquakes occurring during two large (> 10/sup 3/m/sup 3/) hydraulic stimulations of the hydrothermal reservoir at the Baca Location in the Jemez Mountains of northeastern New Mexico are reported. Both stimulations consisted of water, viscosity enhancer, and proppant. The microearthquake event rate was low but variable thro… more

Environmental consequences of postulate plutonium releases from Atomics International's Nuclear Materials Development Facility (NMDF), Santa Susana, California, as a result of severe natural phenomena

Description: Potential environmental consequences in terms of radiation dose to people are presented for postulated plutonium releases caused by severe natural phenomena at the Atomics International's Nuclear Materials Development Facility (NMDF), in the Santa Susana site, California. The severe natural phenomena considered are earthquakes, tornadoes, and high straight-line winds. Plutonium deposition values are given for significant locations around the site. All important potential exposure pathways are e… more

Correlation Between Precision Gravity and Subsidence Measurements at Cerro Prieto

Description: Precision gravity measurements were made in the region of the Cerro Prieto geothermal field at yearly intervals from 1977 to 1981 to assess the feasibility of using gravity to determine subsurface reservoir changes with time. The extent of mass recharge in response to the continued production of fluids from this field was studied. Changes in gravity and ground elevation were observed throughout the region for the period of observation. Results indicate that the largest changes observed were the… more

Inversion modeling of multiple geophysical data sets for geothermal exploration: application to Roosevelt Hot Springs area. Final report

Description: The theoretical basis for modeling the arrival times of local earthquake P waves at a network of seismic stations is described. A technique for separating the dependence of network arrival times on velocity structure from the dependence on the earthquake location parameters is presented. Commented computer listings of the forward modeling algorithms developed in part under DOE support are given. The local arrival time and Bouguer gravity data sets acquired for the Roosevelt and Leach Hot Spring… more

Structural review of the San Onofre Nuclear Generation Station Unit 1 containment structure under combined loads. Systematic Evaluation Program

Description: This report is a structural assessment of the containment structure of the San Onofre Nuclear Generation Station Unit 1, performed for the Nuclear Regulatory Commission as part of the Systematic Evaluation Program (SEP). The San Onofre assessment focused on the overall structural integrity of the containment structure under a safe shutdown earthquake an a postulated design basis accident. The safe shutdown earthquake was represented by the Housner Spectra, scaled to 0.67 g peak ground accelerat… more

Seismic baseline and induction studies: Roosevelt Hot Springs, Utah and Raft River, Idaho

Description: Local seismic networks were established at the Roosevelt Hot Springs geothermal area, utah and at Raft River geothermal area, Idaho to monitor the background seismicity prior to initiation of geothermal power production. The Raft River study area is currently seismically quiet down to the level of approximately magnitude one. The Roosevelt Hot Springs area has low-level seismic activity for M/sub L/ greater than about two; however, microearthquake (M/sub L/ less than or equal to 2) swarms appea… more

Analysis of the Nuevo Leon magnetic anomaly and its possible relation to the Cerro Prieto magmatic-hydrothermal system

Description: The broad dipolar magnetic anomaly whose positive peak is centered near Ejido Nuevo Leon, some 5 km east of the Cerro Prieto I Power Plant, has long been suspected to have a genetic relationship to the thermal source of the Cerro Prieto geothermal system. This suspicion was reinforced after several deep geothermal wells, drilled to depths of 3 to 3.5 km over the anomaly, intersected an apparent dike-sill complex consisting mainly of diabase but with minor rhyodacite. A detailed fit of the obser… more

Seismological studies at the Cerro Prieto field: 1978-1982

Description: Varied seismological studies have been conducted to determine the static and dynamic properties of the Cerro Prieto geothermal field. Sought have been the relation of wave propagation characteristics and microearthquake activity to such features as production boundaries, recharge zones, heat sources, fluid strata, lithology and structure. Discussed here will be the results of the studies carried out by UCB-LBL since 1978 in light of the current knowledge of the Cerro Prieto field. Also included… more

Seismicity related to geothermal development in Dixie Valley, Nevada

Description: A ten-station seismic network was operated in and around the Dixie Valley area from January 1980 to November 1981; three of these stations are still in operation. Data from the Dixie Valley network were analyzed through 30 Jun 1981, and results of analysis were compared with analysis of somewhat larger events for the period 1970-1979. The seismic cycle in the Western Great Basic, the geologic structural setting, and the instrumentation are also described.

Ground motion from earthquakes and underground nuclear weapons tests: a comparison as it relates to siting a nuclear waste storage facility at NTS

Description: Ground motion generated by a magnitude 4.3 earthquake at Massachusetts Mountain on the Nevada Test Site was measured at the control point and compared with ground motion generated at about the same distance by four underground nuclear weapons tests. The depth of the earthquake was between 4 and 4.6 km. The resulting signal at the distance considered was almost entirely body-wave components and had little or no contribution from the surface wave. The motion from the relatively shallower weapons … more
