Maximum Accelerators Caused by Underground Nuclear Explosions in the Oak Spring Formation in Area 12 of the Nevada Test Site at Distances of 5 to 300 Kilometers: a Preliminary Summary

Description: From introduction: The results presented in this preliminary report are principally concerned with the ground motion caused by seven underground nuclear explosions (table 1) in the bedded tuff of the Oak Spring formation in Area 12. Ground motions were recorded at stations as close as 5 kilometers and as far as 300 kilometers from the explosions (fig 1 and table 2). The results for the Bianca and especially the Evans explosion are meager because the first was accompanied by a Test Site-wide moznentary power failure and because the yield of the second was so far below the anticipated yield that uncertain results were obtained. Ground motions caused by most of the air explosions in Operations Plumbbob and Hadtack - Phase 2 were recorded and have been partly analyzed. Results are presented in this report only where they relate significantly to analysis of the underground explosions. The effects of most of the small underground explosions in Area 3 (center of Yucca Flat) that had significant yields were also recorded. The results have not yet been interpreted.

Geologic Reconnaissance of the Topopah Spring and Timber Mountain Quandrangles, Nye County, Nevada

Description: The Topopah Spring and Timber Mountain 15-minute quadrangles comprising about 500 square miles in southern Nye County, Nev., are bounded by longitudes 116°15' W. and 116°30' W. and by latitudes 36°45' N. and 37°15' N. (fig. 1) The quadrangles are mostly within the Nevada Test Site and are approximately 90 miles northwest of Las Vegas (fig. 1). Lathrop Wells, the nearest town, is about 10 miles south of the southern boundary of the Topopah Spring quadrangle.

Analysis Summary of an Assembled Western U.S. Dataset

Description: The dataset for this report is described in Walter et al. (2004) and consists primarily of Nevada Test Site (NTS) explosions, hole collapse and earthquakes. In addition, there were several earthquakes in California and Utah; earthquakes recorded near Cataract Creek, Arizona; mine blasts at two areas in Arizona; and two mine collapses in Wyoming. In the vicinity of NTS there were mainshock/aftershock sequences at Little Skull Mt, Scotty's Junction and Hector ere mine. All the events were shallow and distances ranged from about 0.1 degree to regional distances. All of the data for these events were carefully reviewed and analyzed. In the following sections of the report, we describe analysis procedures, problems with the data and results of analysis.

Records of Wells and Test Holes Drilled at the Nevada Test Site and Vicinity Since 1960

Description: From introduction: "This report was compiled to bring together the well data collected by the U.S. Geological Survey since 1960. This compilation includes data on 63 wells and test holes which were drilled since the Moore reports were prepared, or which were deepened or otherwise modified since 1960."

Environmental Assessment and Finding of No Significant Impact: The Nevada Test Site Development Corporations's Desert Rock Sky Park at the Nevada Test Site

Description: The United States Department of Energy has prepared an Environmental Assessment (DOE/EA-1300) (EA) which analyzes the potential environmental effects of developing operating and maintaining a commercial/industrial park in Area 22 of the Nevada Test Site, between Mercury Camp and U.S. Highway 95 and east of Desert Rock Airport. The EA evaluates the potential impacts of infrastructure improvements necessary to support fill build out of the 512-acre Desert Rock Sky Park. Two alternative actions were evaluated: (1) Develop, operate and maintain a commercial/industrial park in Area 22 of the Nevada Test Site, and (2) taking no action. The purpose and need for the commercial industrial park are addressed in Section 1.0 of the EA. A detailed description of the proposed action and alternatives is in section 2.0. Section 3.0 describes the affected environment. Section 4.0 the environmental consequences of the proposed action and alternative. Cumulative effects are addressed in Section 5.0. Mitigation measures are addressed in Section 6.0. The Department of Energy determined that the proposed action of developing, operating and maintaining a commercial/industrial park in Area 22 of the Nevada Test Site would best meet the needs of the agency.

Nevada Test Site Resource Management Plan: Annual summary, January 2000

Description: The Nevada Test Site Resource Management Plan published in December of 1998 (DOE/NV--518) describes the Nevada Test Site stewardship mission and how its accomplishment will preserve the resources of the ecoregion while accomplishing the objectives of the mission. As part of the Nevada Test Site Resource Management Plan, DOE Nevada Operations Office has committed to perform and publish an annual summary review of DOE Nevada Operations' stewardship of the Nevada Test Site. This annual summary includes a description of progress made toward the goals of the Nevada Test Site Resource Management Plan, pertinent monitoring data, actions that were taken to adapt to changing conditions, and any other changes to the Nevada Test Site Resource Management Plan.

The Nevada Test Site as a Lunar Analog Test Area

Description: The Nevada Test Site (NTS) is a large (1,350 square miles) secure site currently operated by National Security Technologies, LLC (NSTec), for the U.S. Department of Energy and was established in 1951 to provide a venue for testing nuclear weapons. Three areas with a variety of elevation and geological parameters were used for testing, but the largest number of tests was in Yucca Flat. The Yucca Flat area is approximately 5 miles wide and 20 miles long and approximately 460 subsidence craters resulted from testing in this area. The Sedan crater displaced approximately 12 million tons of earth and is the largest of these craters at 1,280 feet across and 320 feet deep. The profiles of Sedan and the other craters offer a wide variety of shapes and depths that are ideally suited for lunar analog testing.

Observations on Faults and Associated Permeability Structures in Hydrogeologic Units at the Nevada Test Site

Description: Observational data on Nevada Test Site (NTS) faults were gathered from a variety of sources, including surface and tunnel exposures, core samples, geophysical logs, and down-hole cameras. These data show that NTS fault characteristics and fault zone permeability structures are similar to those of faults studied in other regions. Faults at the NTS form complex and heterogeneous fault zones with flow properties that vary in both space and time. Flow property variability within fault zones can be broken down into four major components that allow for the development of a simplified, first approximation model of NTS fault zones. This conceptual model can be used as a general guide during development and evaluation of groundwater flow and contaminate transport models at the NTS.
