The Swedish Dialogue Project. An Attempt to Explore How Different Actors May Take Part in the Decision Process Related to Disposal of Radioactive Waste
The Swedish Nuclear Power Inspectorate (SKI) has initiated a project, DIALOGUE, which is exploring the possibility to define review procedures for license applications of nuclear waste...
Nuclear Fuel Waste Disposal: The Canadian Consultative Approach
Over the past two decades society has demanded more public participation and public input into decision-making by governments. Accordingly, development of the Canadian concept for deep...
An Inverse Procedure for Estimating the Unsaturated Hydraulic Conductivities of Volcanic Tuffs
A procedure is developed for estimating the hydraulic conductivity function of unsaturated volcanic tuff, using measurements of the sorptivity and capillary pressure functions. The method...
Scale Dependence of Effective Media Properties
For problems where media properties are measured at one scale and applied at another, scaling laws or models must be used in order to define effective properties at the scale of interest....
Full-Field Dye Concentration Measurement Within Saturated/Unsaturated Thin Slabs of Porous Media
This paper presents a full-field dye concentration measurement technique that extends our experimental capabilities to the measurement of transient dye concentration fields within steady...
Determination of Water Content in Unsaturated Flow Experiments Using TDR and Capacitance
Electromagnetic techniques have been used for many years for the determination of moisture content in materials. We are adapting two of these techniques to the estimation of moisture in...
Inference of Moisture Content in Unsaturated Media Using Ultrasonics
This study focuses on the ability of commercial ulltrasonics equipment to determine the moisture content in unsaturated media. We are interested in the possible application of this technology...
Scenario Development for Safety Demonstration for Deep Geological Disposal in Switzerland
A scenario development procedure has been developed that is appropriate to the safety assessment approach chosen by Nagra and to the Swiss regulatory requirements. The procedure is seen...
A Working Definition of Scenario and a Method of Scenario Construction
The event-tree method of scenario construction has been chosen for the Yucca Mountain performance assessment. Its applicability and suitability to the problem are discussed and compared...
Effect of Interconnection of Fractures on Dispersion in Flow Through Fractured Networks
A stochastic modeling technique in a 2-D discrete fracture network with two orthogonal sets of fractures is developed to investigate mass transport dispersion and to investigate the relation...
Flow and Transport in Hierarchically Fractured Systems
Preliminary results indicate that flow in the saturated zone at Yucca Mountain is controlled by fractures. A current conceptual model assumes that the flow in the fracture system can be...
Modeling Storage Behavior in a Fractured Rock Mass
To represent single bore hole injection tests in fractured rock masses, a transient model has been implemented, based on a three dimensional stochastic description of the fracture network....
Connectivity and the Continuum Approximation in Fracture Flow Modeling
The continuum assumption is frequently made when modeling flow in fractured media. The approach presented in this paper helps evaluating the validity of such an assumption. Two indices...
Automatic Calibration of 3D Finite Differences Model Parameters? Application to the Finnsjon Site (Sweden)
Calibration of 3D finite difference model parameters is usually carried out using a noon-automatic 'manual' procedure until observed heads, for instance, are simulated with a sufficient...
Modeling of Fluid and Solute Transport in Fractured Rock
A new model for flow and solute transport in fractured rock is proposed. It is based on the concept of a network of channels. The individual channel members are given stochastically selected...
Channel Network Models for Solute Migration and Dispersal
We introduce a class of channel-network models for solute migration and dispersal in saturated rock. In discussing the behaviour of any dispersive process it is necessary to compare and...
Solute Transport Characteristics of Fractured Dolomite in Southern Nevada, USA
Recirculating tracer tests in fractured Cambrian dolomite beneath the Amargosa Desert revealed (1) and 83-percent increased in apparent dispersivity resulting from a two-percent increase...
Radionuclide Transport in Fractured Media
Until recently, the classical advective-dispersive transport equation was considered to be an adequate model for describing the motion of a solute (e.g. radionuclides) in porous and fractured...
Procurement Quality Engineering
The 'Procurement Quality Function' is an element of the Body of Knowledge of Quality Engineering, as defined by the American Society for Quality Control (ASQC). This paper describes the...
The Use of Technical Specialists in Quality Assurance Audits
This paper provides a nontechnical discussion of the use of Technical Specialists in quality assurance audits by the Office of Civilian Radioactive Waste Management's Office of Quality...
