Unit decontamination and dismantlement (D&D) costs

Unit decontamination and dismantlement (D&D) costs

Date: March 1, 1996
Creator: Folga, S.; Swanston, R.; Davis, M. & Janke, R.J.
Description: A series of relationships have been developed for estimating unit decontamination and dismantlement (D&D) costs for a number of building types which may be applied in the absence of other data to obtain rough order-of-magnitude (ROM) cost estimates for D&D activities. The relationships were developed using unit D&D costs for a number of building structure types at the Department of Energy Fernald site. These unit costs into account the level of radioactive contamination as well as the, building size.

Integration of sample analysis method (SAM) for polychlorinated biphenyls

Integration of sample analysis method (SAM) for polychlorinated biphenyls

Date: May 1, 1996
Creator: Monagle, M. & Johnson, R.C.
Description: A completely integrated Sample Analysis Method (SAM) has been tested as part of the Contaminant Analysis Automation program. The SAM system was tested for polychlorinated biphenyl samples using five Standard Laboratory Modules{trademark}: two Soxtec{trademark} modules, a high volume concentrator module, a generic materials handling module, and the gas chromatographic module. With over 300 samples completed within the first phase of the validation, recovery and precision data were comparable to manual methods. Based on experience derived from the first evaluation of the automated system, efforts are underway to improve sample recoveries and integrate a sample cleanup procedure. In addition, initial work in automating the extraction of semivolatile samples using this system will also be discussed.

HIPPI: What is it, where did it come from, and where is it going?

HIPPI: What is it, where did it come from, and where is it going?

Date: May 1, 1996
Creator: Tolmie, D.
Description: The first commercial High-Performance Parallel Interface (HIPPI) equipment was delivered in 1988, and HIPPI is the current interface of choice for supercomputers and other high end equipment. HIPPI currently supports data rates of 800 and 1600 Mbit/s. The evolution of HIPPI will be described, including some of the design choices made, describing where the author feels each came from, and the strengths and weaknesses of each. The HIPPI standards committee is now working on a new physical layer interface supporting data transfer rates of 6. 4 Gbit/s, an increase of eight times the current common HIPPI rate. The design objectives will be discussed, and the new interface will be described.

Description: The Low-Level Radioactive Waste Forum is an association of state and compact representatives, appointed by governors and compact commissions, established to facilitate state and compact implementation of the Low-Level Radioactive Waste Policy Act of 1980 and the Low-Level Radioactive Waste Policy Amendments Act of 1985 and to promote the objectives of low-level radioactive waste regional compacts. The LLW Forum provides an opportunity for state and compact officials to share information with one another and to exchange views with officials of federal agencies and other interested parties.

Quantitative prediction of stresses during thermoset cure

Quantitative prediction of stresses during thermoset cure

Date: July 1, 1996
Creator: Adolf, D.; Chambers, B. & Burchett, S.
Description: Two thin-walled Al tubes were filled with epoxy which were cured isothermally; one tube was instrumented with strain gauges, and the other with thermocouples. Finite element codes were used. Predicted and measured centerline hoop strains are shown; predictions and measurements agree. This is being applied to encapsulated components.

Advanced in-duct sorbent injection for SO{sub 2} control. Topical report number 3, Subtask 2.3: Sorbent optimization

Advanced in-duct sorbent injection for SO{sub 2} control. Topical report number 3, Subtask 2.3: Sorbent optimization

Date: November 1, 1994
Creator: Rosenhoover, W.A.; Maskew, J.T.; Withum, J.A. & Stouffer, M.R.
Description: The objective of this research project is to develop second-generation duct injection technology as a cost-effective compliance option for the 1990 Clean Air Act Amendments. Specific process performance goals are to achieve 90% SO{sub 2} removal and 60% sorbent utilization efficiency. Research is focused on the Advanced Coolside process, which has shown the potential of achieving these targets. The objective of Subtask 2.3, Sorbent Optimization, was to explore means of improving performance and economics of the Advanced Coolside process through optimizing the sorbent system. Pilot plant tests of commercial and specially prepared hydrated limes showed that the process is relatively insensitive to sorbent source. This can be an important economic advantage, allowing the use of the lowest cost sorbent available at a site. A pilot plant hydration study conducted in cooperation with Dravo Lime Company further indicated the relative insensitivity of process performance to lime source and to lime physical properties. Pilot plant tests indicated that the use of very small amounts of additives in the Advanced Coolside process can improve performance under some circumstances; however, additives are not necessary to exceed process performance targets.

Creator: Schmidt, D.M.; Wu, A.; Schrimpf, R.D.; Fleetwood, D.M.; Pease, R.L. & Combs, W.E.
Description: The physical mechanisms for gain degradation in laterals PNP bipolar transistors are examined experimentally and through simulation. The effect of increased surface recombination velocity at the base surface is moderated by positive oxide charge.

Hydrologic review services. Final project report, May 24--December 31, 1993

Hydrologic review services. Final project report, May 24--December 31, 1993

Date: October 1, 1995
Creator: Hoopes, J.A.
Description: Research on the runoff, sediment, and contaminant transport in Big Buck Canyon at the Los Alamos National Laboratory began in 1993. The final research goal is to estimate how fast and how much contaminated sediment is moving in the canyon. Due to equation of state experiments involving high explosives, soils in the vicinity of the three test sites have been contaminated with heavy metals such as uranium and cadmium. There are three main parts to the research that will eventually be combined to address the final goal of estimating total contaminant movement. The first part involves the collection and interpretation of experimental field data, such as rainfall and runoff amounts. The second part involves numerical modeling the watershed response to rainfall inputs. The third part involves experimental chemistry work to evaluate the concentration of contaminants in a representative sample of sediment. The details about the model development and testing are presented. The simulation of a large flood in 1991 did not compare well with observations of the event. The model seriously underpredicted the flow out of the watershed because the value of the hydraulic conductivity in the channel was too large. The infiltration of water into the channel bed, known ...

State and national energy environmental risk analysis systems for underground injection control. Final report, April 7, 1992--May 31, 1995

State and national energy environmental risk analysis systems for underground injection control. Final report, April 7, 1992--May 31, 1995

Date: May 1, 1995
Creator: unknown
Description: The purpose of this effort is to develop and demonstrate the concept of a national Energy and Environmental Risk Analysis System that could support DOE policy analysis and decision-making. That effort also includes the development and demonstration of a methodology for assessing the risks of groundwater contamination from underground injection operations. EERAS is designed to enhance DOE`s analytical capabilities by working with DOE`s existing resource analysis models for oil and gas. The full development of EERAS was not planned as part of this effort. The design and structure for the system were developed, along with interfaces that facilitate data input to DOE`s other analytical tools. The development of the database for EERAS was demonstrated with the input of data related to underground injection control, which also supported the risk assessment being performed. The utility of EERAS has been demonstrated by this effort and its continued development is recommended. Since the absolute risk of groundwater contamination due to underground injection is quite low, the risk assessment methodology focuses on the relative risk of groundwater contamination. The purpose of this methodology is to provide DOE with an enhanced understanding of the relative risks posed nationwide as input to DOE decision-making and resource ...
