Isotopic and Trace Element Variability in Altered and Unaltered Tuffs at Yucca Mountain, Nevada
Reference stratigraphic sections near Yucca Mountain, Nevada were established and sampled in outcrop areas where the volcanic rocks have been minimally altered. Isotopic and trace element...

Strontium Isotopic Evidence for a Higher Water Table at Yucca Mountain
At Yucca Mountain, calcite occurs as open-space fillings and coatings on fractures within much of the host volcanic rocks in both the saturated and unsaturated zones. Strontium isotope...

Lead Isotopic Composition of Paleozoic and Late Proterozoic Marine Carbonate Rocks in the Vicinity of Yucca Mountain, Nevada
Paleozoic and Late Proterozoic marine carbonate rocks (limestones, dolomites, and their metamorphic equivalents) cropping out in the vicinity of Yucca Mountain contain lead with an isotopic...

Isotope-Geochemical Investigations of Volcanic Rocks in the Vicinity of the Radiochemical Plant Mayak (Russia)
Russian programmes on radioactive waste management consider a possibility to organize an underground laboratory and subsequently an underground repository for intermediate- and high-level...

Application of the Global Positioning System to Locating Remote Sites
The location of Near Field (NF) sampling stations, used for the radiological monitoring program portion of the site characterization phase of the Yucca Mountain Project, were determined...

IHLW Conference Paper?Yucca Mountain Site Characterization Project Environmental Protection Program
To ensure that characterization of the Yucca Mountain site is conducted in an environmentally safe and sound manner, the U.S. Department of Energy (DOE) has developed and implemented a...

Ambient Air Monitoring to Support HLW Repository Site Characterization
This paper is a description of the program that has been operating in support of the Yucca Mountain site site characterization activities since 1985.The ambient air monitoring is designed...

Project on Contaminations-Radiation-Ecosystems-Health in Russia
We would like to discuss with you a project that we are currently developing, doing research upon and completing. In our report we represent the the following: - a few experimental data...

Ecological Risk Assessment of Proposed Deep Geologic Disposal of High-Level Nuclear Waste in Canada
Using population dynamic models of moose and brook trout, and assuming topographic, hydrographic and other habitat features typical of the Canadian Shield in Ontario, we have estimated...

Defending the Environmental Standpoint: A Report of the Work of Environment Canada in Assessing the Canadian Nuclear Fuel Waste Disposal Concept
Environment Canada, the Canadian environmental department, is participating as an intervenor in the federal environmental assessment of AECL's nuclear fuel waste disposal concept to ensure...

Mercury Porosimetry Studies on a Natural Fracture
Mercury porosimetry techniques were used to study the effects of stress on the capillary pressure characteristics of a single natural fracture. In addition, permeability measurements were...

Small-Scale Behavior of Single Gravity-Driven Fingers in an Initially Dry Fracture
Experiments investigating the behavior of individual, gravity-driven fingers in an initially dry, rough-walled analog fracture are presented. Fingers were initiated from constant flow...

Wetting Front Instability in an Initially Wet Unsaturated Fracture
Experimental results exploring gravity-driven wetting front instability in a pre-wetted, rough-walled analog fracture are presented. Initial conditions considered include a uniform moisture...

Assessing Fault Rupture Hazard for the Proposed Repository at Yucca Mountain, Nevada: Demonstration of a Methodology Using Expert Judgments
As part of the Electric Power Research Institute's High Level Waste (EPRI HLW) performance assessment, we have developed and demonstrated a methodology to estimate the magnitude and likelihood...

HWVP Compliance with the Hanford Site Solid Waste Acceptance Criteria
This report describes the Hanford Waste Vitrification project (HWVP), which will be located at the Haford Site. The Hanford Site encompasses a 560-mi²...

Durability Testing of the High-Capacity GA-4/GA-9 Trailer
General Atomics (GA) is under contract to the US Department of Energy (DOE), Idaho Field Office, to develop two legal-weight truck from-reactor spent-fuel shipping casks with trailers....

Tolerance Requirements for Remote Handling at the Hanford Vitrification Project
A new and innovative approach to installation of the many remote nozzles and electrical connectors that must be installed to demanding tolerances has been developed by the architect/engineer...

Simulating the Behavior of Natural Geological Systems: Sources of Uncertainty and Bias
Post-closure performance assessments are used, in conjunction with controlled laboratory experiments and observations on natural systems, to generate confidence that a radioactive waste...

Yucca Mountain Site Characterization Project Exploratory Studies Facilities Construction Status
This paper discusses the progress to date on the construction planning and development of the Yucca Mountain Site Characterization Project (YMP) Exploratory Studies Facilities (ESF). The...

Application of Indicator Geostatistics to the Gorleben Data Set
This paper describes a trial application of Indicator geostatistical methods to borehole data from the Gorleben site. Indicator variograms have been estimated from the site data and fitted...
