Radiological aspects of dissolving irradiated Li-Al

If a metal shipment from the reactors to a chemical processing plant contained irradiated Li-Al pieces, there would be a release of tritium during processing. Two situations were analyzed -- one where a single piece is inadvertently mixed in a bucket of irradiated uranium metal pieces, and the extreme case where three buckets of Li-Al instead of uranium are sent in a regular well car shipment. One piece contains about 600 curies of H{sup 3} and three buckets of 585, pieces each would contain a … more

Radioactive particles in the 234-5 Building ventilation exhaust

The 234-5 Building ventilation exhaust is continuously sampled for the purpose of estimating the amount of radioactive (alpha emitting) material discharged to the atmosphere. Although a record is kept of the gross amount of radioactive material discharged, few data are available concerning the size and kind of active particles in the exhaust air. Knowledge of the particle size permits: (1) an estimate of the validity of samples drawn through the sampling system, (2) a better knowledge of what t… more

Hazard Analysis for Cesium Shipments

The rail shipment of large quantities of radiocesium involves a potential accidental release of this material in a readily available form to the biosphere. The magnitude of the associated potential damage to man and his environment is evaluated in this report. The evaluation of the consequences of an accidental release of Cs-137 from the Shielded Transfer Tank, Model II (STT) assumes loss of Cs-137 to the atmosphere or to surface-water. Release to the atmosphere could result from a collision fo… more

Toxicity studies of mild gasification products. Quarterly report, October--December 1993

The major hypothesis of carcinogenesis is that malignancy is due to an alteration (mutation) of the genetic material in a somatic cell. Reactive electrophilic metabolites are generated from many chemicals by the action of endogenous mixed-function oxidases. These reactive metabolites may bind to cellular macromolecules, such as DNA, and can, therefore, initiate a mutagenic or carcinogenic event. Prokaryotes and non-mammalian eukaryotes are used in mutation assays, while cultured mammalian cells… more

[Toxicity studies of mild gasification products]. [Quarterly report, January 1, 1993--March 31, 1993]

Both IST No. 9 and IST No. 10 displayed mutagenic activity only in the presence of S9 metabolic activation. The mutagenicity of IST No. 9 to TA98 (with S9 activation) was low, but positively confirmed using both solvents (Table 1) . The mutagenic activity of IST No. 9 was also detected, as noted in Table 1, on TA100 with S9 activation when solvated in DMSO. Although some doubling of the revertant number was noted in confirmatory tests, no dose-response could be elucidated; therefore, the mutage… more

Development of alternatives to lead-bearing solders

Soldering technology, using tin-lead alloys has had a significant role in the packaging of highly functional, low cost electronic devices. The elimination of lead from all manufactured products, whether through legislation or tax incentives, will impact the electronics community which uses lead-containing solders. In response to these proposed measures, the National Center for Manufacturing Sciences has established a multi-year program involving participants from industry, academia, and the nat… more

Early Site Permit Demonstration Program: Guidelines for determining design basis ground motions. Volume 1

This report develops and applies a methodology for estimating strong earthquake ground motion. The motivation was to develop a much needed tool for use in developing the seismic requirements for structural designs. An earthquake`s ground motion is a function of the earthquake`s magnitude, and the physical properties of the earth through which the seismic waves travel from the earthquake fault to the site of interest. The emphasis of this study is on ground motion estimation in Eastern North Ame… more

Oak Ridge Health Studies phase 1 report, Volume 1: Oak Ridge Phase 1 overview

In July 1991, the State of Tennessee initiated the Health Studies Agreement with the United States Department of Energy to carry out independent studies of possible adverse health effects in people living in the vicinity of the Oak Ridge Reservation. The health studies focus on those effects that could have resulted or could result from exposures to chemicals and radioactivity released at the Reservation since 1942. The major focus of the first phase was to complete a Dose Reconstruction Feasib… more

Assessment of mercury health risks to adults from coal combustion

The U.S. Environmental Protection Agency (EPA) is preparing, for the U.S. Congress, a report evaluating the need to regulate mercury (Hg) emissions from electric utilities. This study, to be completed in 1995, will have important health and economic implications. In support of these efforts, the U.S. Department of Energy, Office of Fossil Energy, sponsored a risk assessment project at Brookhaven National Laboratory (BNL) to evaluate methylmercury (MeHg) hazards independently. In the BNL study, … more

Safety issues for hydrogen-powered vehicles

Positron annihilation spectroscopy of overlayers, interfaces, and buried regions of semiconductors has seen a rapid growth in recent years. The characteristics of the annihilation gamma rays depend strongly on the local environment of the annihilation sites, and can be used to probe defect concentrations in a range inaccessible to conventional defect probes. Some of the recent success of the technique in examining low concentrations of point defects in technologically important Si-based structu… more

A global overview of risk management of the DOE complex

No endeavor is risk-fire and as we realize the inherent risks in society, our only viable solution is to manage the risk. Application of an integrated risk management program of a large technological system like the DOE complex is a difficult, task; but it is the only rational means to optimize the risk-benefit equation. An effective risk management culture-within the DOE complex will in the long run, ensure a consistent response to mitigate identified risks. An effective risk management progra… more

Environmental Measurement-While-Drilling system for real-time field screening of contaminants

Sampling during environmental drilling is essential to fully characterize the spatial distribution and migration of near surface contaminants. However, the analysis of these samples is not only expensive, but can take weeks or months when sent to an off-site laboratory. In contrast, measurement-while-drilling (MWD) screening capability could save money and valuable time by quickly distinguishing between contaminated and uncontaminated areas. Real-time measurements provided by a MVM system would… more

Contaminant Distributions at Typical U.S. Uranium Milling Facilities and Their Effect on Remedial Action Decisions

Past operations at uranium processing sites throughout the US have resulted in local contamination of soils and ground water by radionuclides, toxic metals, or both. Understanding the origin of contamination and how the constituents are distributed is a basic element for planning remedial action decisions. This report describes the radiological and nonradiological species found in ground water at a typical US uranium milling facility. The report will provide the audience with an understanding o… more
