Seismic velocities and attenuation in an underground granitic waste repository subjected to heating

Description: The behavior of a granitic rock mass subjected to thermal load has been studied by an acoustic cross-hole technique between four boreholes, over a period of some two years. Velocities between boreholes were obtained from the times-of-flight of pulses of acoustic waves between transducers clamped to the borehole wall. The attenuation was obtained by a spectral ratios technique. When the heater was turned on, the velocities increased rapidly to an asymptotic value. When the heater was turned off,… more

Uncertainty analysis

Description: An evaluation is made of the suitability of analytical and statistical sampling methods for making uncertainty analyses. The adjoint method is found to be well-suited for obtaining sensitivity coefficients for computer programs involving large numbers of equations and input parameters. For this purpose the Latin Hypercube Sampling method is found to be inferior to conventional experimental designs. The Latin hypercube method can be used to estimate output probability density functions, but requ… more

Pen Branch fault program: Consolidated report on the seismic reflection surveys and the shallow drilling

Description: The Pen Branch fault was identified in the subsurface at the Savannah River Site (SRS) in 1989 based upon interpretation of earlier seismic reflection surveys and other geologic investigations (Seismorgraph Services Incorp., 1973; Chapman and DiStefano, 1989; Snipes, Fallaw and Price, 1989). A program was initiated at that time to determine the capability of the fault to release seismic energy (Price and others, 1989) as defined in the Nuclear Regulatory Commission regulatory guidelines, 10 CFR… more

Waste disposal in granite: preliminary results from Stripa, Sweden

Description: The results of this experiment to date indicate that the temperature fields in a rock mass contaning geologic discontinuities can be predicted with accuracy using the simple linear theory of heat conduction. Geologic discontinuities appear to introduce significant non-linear thermomechanical behavior into the rock mass as a result of which the thermally induced displacements are much less than those predicted by the simple theory of thermoelasticity, using laboratory values for Poisson's ratio … more

Seabed disposal project two-dimensional axisymmetric penetrometer simulations

Description: Preliminary two-dimensional, one-constituent hole closure analyses of an experimental apparatus and the flow of in situ ocean sediments following a penetrometer explacement have been performed. Boundary conditions associated with the experimental apparatus were found to greatly affect cavity response. Difficulties were encountered in modelling penetrometer-sediment interfaces and in obtaining smooth stress histories. The use of a different computer code in later analyses led to more realistic p… more

Hanford Contaminated Sediment Stabilization Studies

Description: The major problems with radionuclide waste sites in the 200 Area plateau on the Hanford Reservation is the high degree of toxicity or Hazard Index (HI). Transport Factors (TF) are fortunately low but can increase with time and certainly with episodic events such as explosions or earthquakes. Two major tests involving surface affixation were sponsored by the Atlantic Richfield Hanford Company, one by Dowell using M-166 and the other by Battelle-Northwest comparing many different surface affixant… more

Limits on the thermal energy release from radioactive wastes in a mined geologic repository

Description: The theraml energy release of nuclear wastes is a major factor in the design of geologic repositories. Thermal limits need to be placed on various aspets of the geologic waste disposal system to avoid or retard the degradation of repository performance because of increased temperatures. The thermal limits in current use today are summarized in this report. These limits are placed in a hierarchial structure of thermal criteria consistent with the failure mechanism they are trying to prevent. The… more

Deformation of evaporites near the Waste Isolation Pilot Plant (WIPP) site

Description: Layered evaporite units of Ochoan age in the Delaware Basin are 1000 m thick. They are divided into three stratigraphic units (listed in order of increasing age): the Rustler Formation, the Salado Formation, the Castile Formation. These units, especially the Castile, are deformed along portions of the margin of the Delaware Basin and in some areas internal to the basin. Hypotheses of origin of deformation considered are: gravity foundering; gravity sliding; gypsum dehydration; dissolution; and … more

Radioactivity Associated With Biota and Soils of the 216-A-24 Crib

Description: The 216-A-24 Crib was used from 1958 to 1966 to receive condensate (/sup 137/Cs, /sup 90/Sr) from the 241-A and 241-AX Tank Farms. In 1975, rabbitbrush plants (Chrysothamnus nauseosus) growing on the crib were found to contain radioactive materials. Highest levels of activity and densest stands of rabbitbrush plants were in the center of the second section of the crib where a Geiger--Mueller count rate meter showed surface exposure rates of certain plants to be as high as 125 times background. … more

Simulation of barrier heterogeneity and preferential flow effects on the performance of shallow land burial facilities

Description: Compacted soil barriers constructed at landfill sites have some degree of heterogeneity in hydraulic properties that may lead to a decline in barrier integrity and performance. A computer modeling study of the water dynamics of compacted soil barriers for a mesic site in eastem Tennessee was undertaken to identify possible situations that could lead to barrier failure. A water dynamics model for soil-plant systems (UTM) was applied to three landful construction scenarios, and varying degrees of… more

Two-dimensional simulation of the thermomechanical response of project salt vault including the excavation sequence. Final report

Description: Based on comparisons of the present four-room sequential excavation calculational results with previous two-room simultaneous excavation results and the experimental results, the following may be concluded: (1) The sequence of excavation plays no role in overall deformation response of rooms and pillars, provided that sufficient time (approx. 6 months) lapse exists between the last excavation and the start of the heat source. (2) The assumption of a symmetry plane between Rooms 2 and 3 is valid… more

Analysis of steady state creep of southeastern New Mexico bedded salt

Description: Steady state creep rates have been obtained from a large suite of existing experimental creep data relating to bedded rock salt from the Salado formation of S.E. New Mexico. Experimental conditions covered an intermediate temperature range from 22/sup 0/C to 200/sup 0/C, and shear stresses from 1000 psi (7 MPa) to 6000 psi (31 MPa). An expression, based on a single diffusion controlled dislocation climb mechanism, has been found to fit the observed dependence of steady state creep rate on shear… more

Rate of deformation in the Pasco Basin during the Miocene as determined by distribution of Columbia River basalt flows

Description: Detailed mapping of over 8000 square kilometers and logs from 20 core holes were used to determine the distribution and thickness of basalt flows and interbeds in the Pasco Basin. The data indicate the high-MgO Grande Ronde Basalt and Wanapum Basalt thicken from the northeast to the southwest. Deformation began in late Frenchman Springs time in the Saddle Mountains along a northwest-southeast trend and in Roza time along an east-west trend. By late Wanapum time, basalt flows were more restricte… more
