??⁴U/??⁸U as a Ground-Water Tracer, SW Nevada-SE California
The ²³⁴U/²³⁸U ratio of uranium in oxidizing ground waters is potentially an excellent ground-water tracer...

Subsurface Transport of Radioactive Material Using Adaptive Finite Elements
A finite element method which utilizes mesh adaptation is used to calculate transient groundwater flow and pollutant transport. Mass lumping and reduced integration are employed to enhance...

The SECO Suite of Codes for Site Performance Assessment
Modeling for performance assessment of the Waste Isolation Pilot Plant (WIPP) has led to development of the SECO suite of codes for groundwater flow, particle tracking, and transport....

Groundwater Flow Modelling for the TVO-92 Safety Analysis of Spent Fuel Disposal
The TVO-92 safety analysis of spent fuel disposal is based on preliminary site investigations carried out at five sites in Finland between 1987 and 1992. Groundwater flow analyses have...

Modeling of Saturated Zone at Yucca Mountain, Nevada
This paper presents preliminary results of groundwater modeling of the saturated zone in the vicinity of Yucca Mountain. The analysis used both a regional (approximately 250 ? 250 km)...

A Galerkin Method for the Convection?Diffusion Equation Using Asymmetric Weighting Functions
A variation of the Petrov-Galerkin method of solution of a partial differential equation is presented in which the weight function applied to the time derivative term of a one-dimensional...

Functional Analysis of the Exploratory Studies Facility
This paper discusses the development of the 'Physical System Requirements-Exploratory Studies Facility' (PSR-ESF) document. Based on a functional analysis approach, this document includes...

Integrated Test Evaluation Decision Framework for the Yucca Mountain Project
An Integrated Test Evaluation decision framework and computer model were developed to help prioritize site-characterization tests at Yucca Mountain. An initial application of the framework...

Roadmapping: A Management Tool
Roadmapping is a process used by the U.S. Department of Energy (DOE) Office of Environmental Restoration and Waste Management (EM) to illustrate issue-based planning activities necessary...

Crisis Management Training at Nuclear Facilities: Simulations in Bomb Threats
Substantial enhancements to the study of the theoretical and applied foundations of crisis management have been achieved in recent years. Whereas risk managers study 'the probability that...

Software Quality Assurance on the Yucca Mountain Site Characterization Project
The Yucca Mountain Site Characterization Project (YMP) has been involved over the years in the continuing struggle with establishing acceptable Software Quality Assurance (SQA) requirements...

Qualification of Existing Data for the Yucca Mountain Site Characterization Project
The U.S. Department of Energy (DOE) has completed its first effort to qualify existing data using NUREG-1298 'Qualification of Existing Data for High-Level Nuclear Waste Repositories'....

Yucca Mountain Site Characterization Project Performance Based Q List
In mid-1992, the Yucca Mountain Site Characterization Project (YMP) initiated a performance based 'Q' List development effort. This effort is intended to evolve a 'Q' List based upon the...

Development of the Office of Civilian Radioactive Waste Management's Self-Assessment Program
This paper describes the development and implementation of the Self-Assessment (SA) Program of the Office of Civilian Radioactive Waste Management (RW). The basis for RW's SA program is...

Application of Quality Assurance to Site Characterization
Siting studies for nuclear power plants are conducted for the purpose of determining the suitability of the site (a natural system) on plant systems that prevent the release of radioactive...

Potential Nuclear Material Safeguards Applied to the Department of Energy's Civilian Radioactive Waste Management System
The Office of Civilian Radioactive Waste Management (OCRWM) within the U.S. Department of Energy is charged with the responsibility of safe and efficient disposal of this Nation's civilian...

Safeguards Issues of Radioactive Wastes at DOE Sites
Radioactive waste management is not regarded as a safeguard-sensitive step in the nuclear fuel cycle. However, the accumulation of large amounts of fissile materials in wastes over a period...

Safeguards and Security Issues at the MRS Facility
The U.S. Department of Energy's (DOE) Office of Civilian Radioactive Waste Management (OCRWM) is responsible for disposing of the nation's high level radioactive waste in a way that ensures...

Borehole Security on the Yucca Mountain Project
A borehole security plan was developed and is being implemented to address safety, environmental protection and restoration, waste isolation, and security concerns related to boreholes...

Safety Envelope Input: Nuclear Facility Isotopic Content (NFIC) Management System
