Report discussing earthquake activity in the United States during 1962. The report is broken down by regions and has sections for specific earthquakes.

The Yucca Mountain Project/Spent Fuel program at Argonne National Laboratory is designed to determine radionuclide release rates by exposing high-level waste to repository-relevant groundwater. To gain experience for the tests with spent fuel, a scoping experiment was conducted at room temperature to determine the uranium release rate from an unirradiated uranium dioxide powder mixture (14.3 wt % enrichment in uranium-235) to J-13 water under saturated conditions. Another goal set for the experiment was to develop a method for utilizing isotope dilution techniques to determine whether the dissolution rate of uranium dioxide matrix is in accordance with an existing kinetic model. Results of these analyses revealed unequal uranium dissolution rates from the enriched and depleted portions of the powder mixture because of undisclosed differences between them. Although the presence of this inhomogeneity has precluded the application of the kinetic model, it also provided an opportunity to elaborate on the utilization of isotope dilution data in recognizing and quantifying such conditions. Detailed listings of uranium release and solution chemistry data are presented. Other problems commonly associated with spent fuel, such as the effectiveness of filtering media, the existence of uranium concentration peaks during early stages of the leach tests, the need for …

Abstract: "Fifteen in situ interval densities were calculated from the borehole gravity meter observations made in Test Well-B. The weighted average density for all the rocks sampled by the gravity meter is 1.83 gm/cc. The alluvium density ranges from 1.71 to 1.82 gm/cc and averages 1.76 gm/cc. The lake beds range from 1.91 to 1.93 gm/cc and average 1.92 gm/cc. The Rainier Mesa Member averages 1.83 gm/cc. The Tiva Canyon Member averages 1.74 gm/cc and the upper 110 feet of Topopah Spring Member has a density of 2.30 gm/cc."

A program was established for DOE Environmental Restoration and Waste Management (EM) to evaluate factors that are anticipated to affect waste glass reaction during repository disposal, especially in an unsaturated environment typical of what may be expected for the proposed Yucca Mountain repository site.

From abstract and summary: Project Stagecoach consisted of the detonation of three 40,000-pound charges. Blocks of cast TNT were stacked to resemble a sphere and, the whole center-detonated.

This report describes the Sandia Corporation participation and results related to Project Buckboard: the detonation of three 40,000-pound and ten 1000-pound high-explosive charges in basalt rock to establish depth -of-burst curves.

From introduction: "This report presents physical property data of volcanic rocks underlying Rainier Mesa and vicinity in the northwest corner of the Yucca Flat area, Nevada Test Site."

Report containing information regarding the airborne radiometric equipment intercalibration exercises undertaken by four government agencies and one private companies.

The following report is a compilation of lithologic logs, drillers logs, drilling records, and hydrologic data on 18 wells and test holes that were drilled in the Nevada Test Site and surrounding areas prior to 1960.

From introduction: USGS is appraising the possibility, however slight, that the ground water beneath the Nevada Test Site, possibly contaminated by nuclear detonations, may carry radioactive fission products to places where they may constitute a public hazard.

Abstract: Geophysical logs, a summary of contract costs, detailed descriptions of drilling, casing, cementing, and hydraulic testing operations, X-ray mineralogical analyses, physical property analyses, and a detailed lithologic log are presented in the report.

Introduction: The U.S. Geological Survey is appraising the possibility, however slight, that the ground water beneath the Nevada Test Site, possibly contaminated by nuclear detonations, may carry radioactive fission products to places where they may constitute a public hazard.

From introduction: The gravity survey of the Nevada Test Site and contiguous areas of southern Nevada and southeastern California has been made by the U.S. Geological Survey on behalf of the U.S. Atomic Energy Commission. The objective of this study is to delineate and interpret gravity anomalies and regional trends so that the configuration and depth of the buried erosional surface of the Paleozoic rocks may be determined.

Abstract: As a part of continuous geologic and geophysical investigations at the Nevada Test Site, gamma-radioactivity measurements are being made in tunnels and drill holes to determine semiquantitatively the natural gamma radioactivity of geologic formations and the distribution of nuclear-explosion-produced radioisotopes.

The objective of Project 30.7 was to investigate the predicted behavior of German underground personnel shelters, equipment, and certain instrumentation. Data obtained will be used for evaluation and improvement of present design criteria.

Report discussing "descriptions of the HPRR and the Co^60 source, their operating procedures, the manner in which they will be used, and possible hazards are included."

From introduction: Under the general supervision of the Health Division of the Los Alamos Scientific Laboratory, the U.S. Geological Survey is participating in geologic and hydrologic studies of the tile field constructed in Jackass Flats in the southwestern part of the Nevada Test Site as related to waste disposal, M. D. Shutler rendered valuable assistance in obtaining and evaluating portions of the data in this report. These investigations were done on behalf of the U.S. Atomic Energy Commission and were supported by the Division of Reactor Development and by the Albuquerque Operations Office.

From introduction: This report summarizes the available hydrologic information for a part of Nevada surrounding the Nevada Test Site. It emphasizes the possibility that ground water may move from one basin to another, whereas the usual concept heretofore has been that the ground water of the region generally occurs in basins that are closed or nearly closed.

Introduction: The chemical character of ground water depends to a large degree upon the character of the rock formations through which the water moves. The composition of the water is the result of several solutional and decompositional processes.

Introduction: The United States Atomic Energy Commission is considering the establishment of a townsite in the vicinity of Mercury, Nevada, to facilitate operations at the Nuclear Rocket Development Station on the Nevada Test Site.

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."
