Activation of cobalt by neutrons from the Hiroshima bomb

Description: A study has been completed of cobalt activation in samples from two new locations in Hiroshima. The samples consisted of a piece of steel from a bridge located at a distance of about 1300 m from the hypocenter and pieces of both steel and concrete from a building located at approximately 700 m. The concrete was analyzed to obtain information needed to calculate the cobalt activation in the two steel samples. Close agreement was found between calculated and measured values for cobalt activation … more

Activation of oncogenes by radon progeny and x-rays

Description: The overall goal of this proposal is to study the carcinogenic effect of both high and low LET radiation at the molecular level, utilizing techniques developed in molecular biology, cancer cell biology and radiation biology. The underlying assumption is that malignant transformation of normal cells is a multistep process requiring two or more molecular events in the genomic DNA. We hypothesize that radiation may induce such events in one or more steps of the multistep process. We will use in vi… more

Activation product safety in the ARIES-I reactor design

Description: The ARIES design effort has sought to maximize the environmental and safety advantages of fusion through careful selection of materials and careful design. Three goals are that the reactor achieve inherent or passive safety, that no public evacuation plan be necessary and that the waste be disposable as 10CFR61 Class C waste. The ARIES-I reactor consists of a SiC composite structure for the first wall and blanket, cooled by 10 MPa He. The breeder is Li{sub 2}ZrO{sub 3}, although Li{sub 2}O and … more

Active Sites Environmental Monitoring Program: Program plan

Description: DOE Order 5820.2A requires that low-level waste (LLW) disposal sites active on or after September 1988 and all transuranic (TRU) waste storage sites be monitored periodically to assure that radioactive contamination does not escape from the waste sites and pose a threat to the public or to the environment. This plan describes such a monitoring program for the active LLW disposal sites in SWSA 6 and the TRU waste storage sites in SWSA 5 North. 14 refs., 8 figs.

Acute Environmental Toxicity and Persistence of DEM, a Chemical Agent Simulant: Diethyl Malonate. [Diethyl Malonate]

Description: The purpose of the following chemical simulant studies is to assess the potential acute environmental effects and persistence of diethyl malonate (DEM). Deposition velocities for DEM to soil surfaces ranged from 0.04 to 0.2 cm/sec. For foliar surfaces, deposition velocities ranged from 0.0002 cm/sec at low air concentrations to 0.05 cm/sec for high dose levels. The residence times or half-lives of DEM deposited to soils was 2 h for the fast component and 5 to 16 h for the residual material. DEM… more

Adaptation of an Industrial Application for an Instructional Laboratory in Mechanical Vibrations

Description: Extensive theoretical treatment is given to damping as the process of energy dissipation during mechanical vibration. The challenge in the classroom is to adequately convey this concept and extend it by teaching students practical applications in engineering analysis and design. Students are motivated by real-world problems; applying these types of problems with strong instructional classroom content significantly enhances the learning environment. This paper proposes the adaptation of an actua… more

Adaptation of Sw-846 Methodology for the Organic Analysis of Radioactive Mixed Wastes

Description: Modifications to SW-846 sample preparation methodology permit the organic analysis of radioactive mixed waste with minimum personal radiation exposure and equipment contamination. This paper describes modifications to SW-846 methods 5030 and 3510-3550 for sample preparation in radiation-zoned facilities (hood, glove box, and hot cell) and GC-MS analysis of the decontaminated organic extracts in a conventional laboratory for volatile and semivolatile organics by methods 8240 and 8270 (respective… more

Adaptation of the IBM ECR (electric cantilever robot) robot to plutonium processing applications

Description: The changing regulatory climate in the US is adding increasing incentive to reduce operator dose and TRU waste for DOE plutonium processing operations. To help achieve that goal the authors have begun adapting a small commercial overhead gantry robot, the IBM electric cantilever robot (ECR), to plutonium processing applications. Steps are being taken to harden this robot to withstand the dry, often abrasive, environment within a plutonium glove box and to protect the electronic components again… more

Adapting an x-ray/debris shield to the cascade ICF power plant: Neutronics issues

Description: A neutronics analysis has been carried out to determine the effects on the Cascade ICF reactor concept of adding a solid-lithium x-ray and debris shield to each ICF capsule. Results indicate that tritium breeding in LiAlO{sub 2} is possible with a modest isotopic enhancement in {sup 6}Li (to 15%). The shallow-burial index is greater than 1 (indicating that deep burial may be required) if the blanket is kept in the reactor for more than 2.5 yr. Nine percent of the total thermal power is unrecove… more

Adapting sensory data for multiple robots performing spill cleanup

Description: This paper describes a possible method of converting a single performing robot algorithm into a multiple performing robot algorithm without the need to modify previously written codes. The algorithm to be converted involves spill detection and clean up by the HERMIES-III mobile robot. In order to achieve the goal of multiple performing robots with this algorithm, two steps are taken. First, the task is formally divided into two sub-tasks, spill detection and spill clean-up, the former of which … more

Adducts in Sperm Protamine and DNA (Deoxyribonuclease) vs. Mutation Frequency

Description: In mammals, variability in the genetic sensitivity of different germ-cell stages to mutagens could be the result of how much chemical reaches the different stages, what molecular targets may be affected in the different stages and whether or not repair of lesions occurs. In the mouse, several mutagens have been found that cause their greatest genetic damage in late-spermatid and early-spermatozoa stages and that also bind very strongly to the protamine in these stages. Chemicals which are less … more

Adhesion at ceramic interfaces

Description: Many of the properties associated with ceramic materials such as high hardness, high dielectric constant, refractoriness, and good optical properties will play a critical role in the development of devices for new and emerging technologies. In many cases, the combination of properties that is required demands that a composite material be designed to fulfill these complex materials needs. The increasing emphasis upon composite materials design and performance necessarily focuses greater attentio… more

Adirondack Lakes Survey: An Interpretive Analysis of Fish Communities and Water Chemistry, 1984--1987

Description: The Adirondack Lakes Survey Corporation (ALSC) was formed as a cooperative effort of the New York State Department of Environmental Conservation and the Empire State Electric Energy Research Corporation to better characterize the chemical and biological status of Adirondack lakes. Between 1984 and 1987, the ALSC surveyed 1469 lakes within the Adirondack ecological zone. As a follow-up to the survey, the ALSC sponsored a series of interpretive analyses of the ALSC data base.

Adsorption characteristics of PCBs to resins, whole cells, cell and tissue components, and biomolecules

Description: Polychlorinated biphenyls (PCBs) have been designated hazardous chemicals by the US Environmental Protection Agency (EPA). Although PCBs and PCB-containing oils have not been in use since 1977, they persist in the environment. They are known to be absorbed by various aquatic organisms, birds, and mammals. The nature of these affinities is not known. In this study, the Institute of Gas Technology (IGT) compared the adsorption phenomenon of PCBs on commercial resins, whole bacterial cells, cell a… more
