Certifying the TN-BRP and TN-REG Transportable Storage Demonstration Casks
The U.S. Department of Energy (DOE) has obtained U.S. Nuclear Regulatory Commission (NRC) certification to transport two transportable storage casks for a demonstration project. Because...

Controlling the Description of a High-Level Radioactive Waste Isolation System
Control of large, complex, regulation-driven programs using traditional management methods has not been wholly effective. What is needed is a rigorous yet flexible method that is amenable...

Strain Distribution in Fault Zones and Fluid Flow
Field and laboratory studies have shown that mechanical shearing in fault zones produces a repeatable fabric that changes with increasing shear strain. In the brittle field of mechanical...

Compilation/Validation of Thermodynamic Data for Plutonium for Nuclear Waste Disposal: 1. Preliminary Results
A provisional thermodynamic database for plutonium has been compiled from a review of available data and other critical compilations. The database was compared to tabulations of Gibbs...

Lubrication Theory Analysis of the Permeability of Rough-Walled Fractures
Lubrication theory is used to study the permeability of rough-walled rock fractures. Two idealized models of a fracture, in which the roughness follows a sinusoidal or a sawtooth variation,...

Predicted Thermal and Stress Environments in the Vicinity of Repository Openings
An understanding of the thermal and stress environment in the vicinity of repository openings is important for preclosure performance considerations and worker health and safety considerations...

Disposal of Vitrified Waste in an Unsaturated Environment
An experimental program is described wherein the effect of important independent variables on glass reaction under conditions that may exist for unsaturated storage is examined. The effect...

Development of a Structural Model to Analyze Public Opinion on a High-Level Radioactive Waste Facility
Studies show that Nevada residents and state officials oppose the proposed high-level radioactive waste repository project at Yucca Mountain. Nevada residents view the Yucca Mountain repository...

Field Investigations for Seismic Effects on Mechanical and Geohydrologic Response of Underground Structures in Jointed Rock
An exploratory Seismic Rock Mechanics research program has been initiated by the U.S. Nuclear Regulatory Commission at the Center for Nuclear Waste Regulatory Analyses (CNWRA) to study...

Boundary Integral Methods for Unsaturated Flow
A boundary integral equation method (BIEM) is described for numerical analysis of quasilinear steady unsaturated flow in homogeneous material. The applicability of the exponential model...

Effect of a Low-Permeability Layer on Calculated Gas Flow at Yucca Mountain
Yucca Mountain is being studied to determine its suitability as a location for a high-level nuclear waste repository. The mountain is a steep-sided linear ridge which is underlain by a...

The Integrated Performance Assessment in SKI Project-90
The SKI Project-90 is a performance assessment of a hypothetical repository system with KBS-3 features in crystalline rock. A large part of the effort has been to identify and characterize...

Testing of Materials and Scale Models for Impact Limiters
Aluminum Honeycomb and Polyurethane foam specimens were tested to obtain experimental data on the material's behavior under different loading conditions. This paper reports...

Comparison of Elastic and Inelastic Analysis and Test Results for the Defense High Level Waste Shipping Cask
In the early 1980's, the U.S. Department of Energy/Defense Programs (DOE/DP) initiated a project to develop a safe and efficient transportation system for defense high level...

Modelling of Excavation, Thermal Loading and Bentonite Swelling Pressure for a Waste Repository
For the performance assessment of a future nuclear waste repository, the excavation of the tunnel and deposition hole, thermal loading from waste heat release and the swelling pressure...

Scenario Evolution: Interaction Between Event Tree Construction and Numerical Analyses
Construction of well-posed scenarios for the range of conditions possible at any proposed repository site is a critical first step to assessing total system performance. Event tree construction...

A Formalism to Generate Probability Distributions for Performance-Assessment Modeling
A formalism is presented for generating probability distributions of parameters used in performance-assessment modeling. The formalism is used when data are either sparse or nonexistent....

Three-Dimensional Thermal Analysis for Temperature Distribution in Geological Formation
A three-dimensional conduction heat transfer program has been developed for use on microcomputer for thermal analysis of a conductive medium subject to, finite length heat sources. The...

System Analysis Dual-Purpose Repository New Results of Temperature Calculations
As design concept for a high-level waste (HLW) final repository the emplacement of reprocessing wastes and spent fuel elements of different types in a common repository is being studied...

Interim Storage of Solidified High Level Wastes
Indian approach to the problem of interim storage of vitrified high level wastes, indicating design philosophy adopted for air cooled vault at Tarapur has been described. Important design...
