Quest for the Perfect Cap
Exhuming and treating wastes may not always be the most effective way to remediate a site. In some cases, in-place disposal with a protective cap offers the best protection for human health...
Computer-Aided Cleanup
In late 1992, the remedial investigation of Operable Unit 2 at the Department of Energy's Fernald Superfund site in Ohio was in trouble. Despite years of effort-including...
Revenue Enhancement for Water and Wastewater Systems
This proceedings,
Spoils of War
Watertown Arsenal, a former U.S. Army arsenal and nuclear research site noted for its innovations in armament technology, has been shut down and is destined to be returned to civilian...
Quality Assurance for Hazardous-Waste Projects
An important aspect of an environmental Quality Assurance (QA) Program, as with any system designed to improve quality of performance, is the specification of objectives which, if met,...
Technical Evaluations Necessary for Determining Site Suitability for a High-Level Waste Repository
Congress, under the Nuclear Waste Policy Act of 1982, as amended, has charged the Department of Energy with the responsibility for safely and permanently disposing of high-level radioactive...
An Overview of Analysis and Regulatory Needs to Determine Seismic Loads for Design of a High-Level Waste Geologic Repository
Determination of seismic loads and faulting hazard for siting, design and performance evaluation of a high-level nuclear waste repository facility can be accomplished with state-of-knowledge...
Performance Goal Based Seismic Design Criteria for High Level Waste Repository Facilities
This paper proposes a set of deterministic seismic design and evaluation criteria based upon a specified probabilistic seismic performance goal for High Level Waste Repository (HLWR) facilities....
Assessment of the Potential for Tectonic Fault Rupture for High-Level Nuclear Waste Repositories
Active faults that extend to or near the Earth's surface may threaten the safety of engineered structures. The threat can be mitigated by appropriate siting and design, which requires...
Probabilistic Analysis of Faulting Associated with Earthquakes for Nuclear Waste Repositories
The probabilistic analysis of seismogenic faulting follows the same general methodology as the more common seismic hazard analysis for shaking. The main difference lies in the influence...
Tectonic Characterization of a Potential High-Level Nuclear Waste Repository at Yucca Mountain, Nevada
Tectonic characterization of a potential high-level nuclear waste repository at Yucca Mountain, Nevada, is needed to assess seismic and possible volcanic hazards that could affect the...
Geometric Models of Faulting at Yucca Mountain
Yucca Mountain, Nevada, is currently being studied as a potential site for a geologic repository of high-level radioactive waste. Alternative conceptual tectonic models are expected to...
Probabilistic Seismic Design Considerations for a High-Level Nuclear Waste Repository
Earthquakes in the vicinity of an underground high-level waste (HLW) repository have potential effects that must be estimated during the design of the facility. The production facilities...
Preliminary Report: The Little Skull Mountain Earthquake, June 29, 1992
The Little Skull Mountain earthquake occurred about 20 km from the potential high level nuclear repository at Yucca Mountain. The magnitude was 5.6, and the focal mechanism indicates normal...
Current Plans to Characterize the Design Basis Ground Motion at the Yucca Mountain, Nevada Site
A site at Yucca Mountain Nevada is currently being studied to assess its suitability as a potential host site for the nation's first commercial high level waste repository. The DOE has...
Estimation of Near-Regional Seismic Ground Motion from Underground Nuclear Explosion Tests
A problem unique to the location of a nuclear waste repository adjacent to the Nevada Test Site is the assessment of seismic ground motion from potential underground nuclear explosion...
Design of Underground Repository Openings in Hard Rock to Accommodate Vibratory Ground Motions
A methodology and preliminary application for designing repository openings to withstand vibratory ground motions is presented. The methodology first establishes the design basis ground...
Seismic Design of Circular-Section Concrete-Lined Underground Openings?Preclosure Performance Considerations for the Yucca Mountain Site
Yucca Mountain, the potential site of a repository for high-level radioactive waste, is situated in a region of natural and man-made seismicity. Underground openings excavated at this...
Seismic Considerations in Sealing a Potential High-Level Radioactive Waste Repository
The potential repository system is intended to isolate high-level radioactive waste at Yucca Mountain according to the performance objective - 10 CFR 60.112. One subsystem that may contribute...
Options for Dynamic Analyses of Underground Facilities
Continuum and discontinuum modeling techniques for conducting dynamic analysis of underground facilities of geologic repository are discussed. Compared with continuum analysis, the discontinuum...
