The EGCR was designed to accommodate up to four gascooled experimental loops plus several experimental fuel elements in the open core. Two of the loops will utilize 51/2-in.-O.D. stainless steel tubes passing through the core along an axis which is about 17 in. from the central axis of the core. The other two loops will utilize 91/2-in.-o.d. tubes about 68 in. from the central axis. Inherent safety in the design, facility design, primary loop design, auxiliary systems and equipment design, primary and secondary containment design, instrumentation and controls, and special operations are discussed.

A fluidized-bed incineration facility has been designed for installation at the Rocky Flats Plant. The purpose is to develop and demonstrate the process for the combustion of transuranic waste. The unit capacity will be about 82 kg/hr of combustible waste. The combustion process will utilize in situ neutralization of acid gases generated in the process. The equipment design is based on data generated on a pilot scale unit and represents a scale-up factor of nine. Title II engineering is complete and construction work has begun.

The effort reported is a continuation of the development testing of the 1.5-ton solar desiccant air conditioner (SODAC) and is concerned with determination of the SODAC performance in the recirculated and ventilated mode configuration. Test data in the recirculated mode are presented. As originally conceived, the SODAC features two-speed indoor and outdoor fans to permit more efficient operation at reduced capacity. In both full-flow and half-flow cases, the experimental data are compared to computer predictions. The system and its operation are described, as are the system test facility and procedures. The system description includes the characteristics of the major components, the performance at design conditions, and the control schemes for optimum operation in various climates. (LEW)

The tunnel in this model of construction is 3-1/2 feet wide by 5 feet high. It is assumed that the tunnel contains a rail system and guidance system for: (1) An enclosed car used for transport of 2 people and some tools. (2) A magnet mover. This robot could pick up a magnet and transport it at about 10 miles per hour. (3) An alignment robot. The alignment robot would intercept E.M. waves (microwaves, lasers) to determine its position in the tunnel. Then workers could come along inside the tunnel hoop and nail it together and to the floor. The trench would then be back-filled with a 1 foot berm on top. A rail system would be installed and a support stand for the magnet.

The scientific aims of this project have been the evaluation and dissemination of key nuclear reactions in nuclear astrophysics, with a focus on ones to be studied at new radioactive beam facilities worldwide. These aims were maintained during the entire funding period from 2003 - 2006. In the following, a summary of the reactions evaluated during this period is provided. Year 1 (2003-04): {sup 21}Na(p,{gamma}){sup 22}Mg and {sup 18}Ne({alpha},p){sup 21}Na - The importance of the {sup 21}Na(p,{gamma}){sup 22}Mg and the {sup 18}Ne({alpha},p){sup 21}Na reactions in models of exploding stars has been well documented: the first is connected to the production of the radioisotope {sup 22}Na in nova nucleosynthesis, while the second is a key bridge between the Hot-CNO cycles and the rp-process in X-ray bursts. By the end of Summer 2004, our group had updated these reaction rates to include all published data up to September 2004, and cast the reaction rates into standard analytical and tabular formats with the assistance of Oak Ridge National Laboratory's computational infrastructure for reaction rates. Since September 2004, ongoing experiments on these two reactions have been completed, with our group's participation in both: {sup 21}Na(p,{gamma}){sup 22}Mg at the TRIUMF-ISAC laboratory (DRAGON collaboration), and 18Ne({alpha},p){sup …

The experimental results from the Phase I effort were extremely encouraging. During Phase I PHDs Co. made the first strides toward a new detector technology that could have great impact on synchrotron x-ray absorption (XAS) measurements, and x-ray detector technology in general. Detector hardware that allowed critical demonstration measurements of our technology was designed and fabricated. This new technology allows good charge collection from many pixels on a single side of a multi-element monolithic germanium planar detector. The detector technology provides “dot-like” collection electrodes having very low capacitance. The detector technology appears to perform as anticipated in the Phase I proposal. In particular, the 7-pixel detector studied showed remarkable properties; making it an interesting example of detector physics. The technology is enabled by the use of amorphous germanium contact technology on germanium planar detectors. Because of the scalability associated with the fabrication of these technologies at PHDs Co., we anticipate being able to supply larger detector systems at significantly lower cost than systems made in the conventional manner.

We summarize the observations of unusual optical properties of shocked liquid deuterium (D{sub 2}) that led to proposing spectroscopic measurements. The apparatus built for the measurements is briefly described, along with some representative results in a test material. Unfortunately, spectroscopic measurements were not performed in shocked D{sub 2} during the course of the project. Some reasons are noted.

This booklet is designed to inform the public about what Argonne National Laboratory is doing to monitor its environment and to protect its employees and neighbors from any adverse environmental impacts from Argonne research. The Downers Grove South Biology II class was selected to write this booklet, which summarizes Argonne's environmental monitoring programs for 2006. Writing this booklet also satisfies the Illinois State Education Standard, which requires that students need to know and apply scientific concepts to graduate from high school. This project not only provides information to the public, it will help students become better learners. The Biology II class was assigned to condense Argonne's 300-page, highly technical Site Environmental Report into a 16-page plain-English booklet. The site assessment relates to the class because the primary focus of the Biology II class is ecology and the environment. Students developed better learning skills by working together cooperatively, writing and researching more effectively. Students used the Argonne Site Environmental Report, the Internet, text books and information from Argonne scientists to help with their research on their topics. The topics covered in this booklet are the history of Argonne, groundwater, habitat management, air quality, Argonne research, Argonne's environmental non-radiological program, radiation, and …

It was determined that a radioactive waste leak in the Hanford S Farm in the vicinity of the S-102 retrieval pump discharge occurred because of over-pressurization and failure of the S-102 dilution water supply hose while operating the retrieval pump in reverse with an obstructed suction cavity and an unobstructed flow path to the dilution water supply hose. This report describes efforts to identify plausible scenarios for the waste leak to occur.

The U.S. Department of Energy’s (DOE) commitment to assuring the health and safety of its workers includes the conduct of illness and injury surveillance activities that provide an early warning system to detect health problems among workers. The Illness and Injury Surveillance Program monitors illnesses and health conditions that result in an absence, occupational injuries and illnesses, and disabilities and deaths among current workers.

The purpose of this study is to assess the economic and social effects of projected geothermal resource development for both direct use and electric power generation and to analyze local regulatory policy options designed to mitigate adverse effects. The key issues are land use, fiscal and public infrastructure systems, demography, and the local economy. The study has seven elements: a computer-based inventory and analysis of land characteristics, constraints, sensitivity, and suitability for various land uses; projections of direct and electric geothermal development; primary and induced economic activity using an input-output model; demographic changes; the land and infrastructural demand created; an assessment of the economic and social effects of various configurations in land use that could result; and an analysis of various local regulatory policy options to mitigate adverse effects. The study is a cooperative effort among two national laboratories, a regional agency, and the four Geysers-area counties (Lake, Mendocino, Napa, and Sonoma). The assessment results are intended to guide Department of Energy planners on the environmental consequences of program implementation. The regulatory policy analysis is intended for local officials who are implementing development-management policy.

A state-of-the-art battery survey and data verification process were conducted with battery manufacturers and organizations involved in battery technology research and development. This report addresses those major battery technologies which were identified as either being developed or explored as potential candidates for major energy storage applications in electric utilities or transportation as well as for future operations with solar or wind energy systems. Near- and far-term battery systems, current data and opinions, and developments in both US and foreign battery technology for utility load leveling and electric vehicles are discussed. Background information and the scope of the report are given first. Then basic data for each battery type are summarized; a general discussion of other potential battery systems is also included. A comparative summary of battery cost and performance is presented; actual battery capabilities are discussed relative to the general requirements of electric utility load leveling and transportation applications. The current status of the scarce materials and environmental and safety problems related to battery technology is presented. The overall status of the current R and D programs and expected progress toward commercialization are discussed; the roles of competing technologies in two major markets for battery technology are addressed. General observations, …

It has been proposed by R.R. Wilson and L. Lederman that it may be advantageous and cheaper to construct a large accelerator (> 10 TeV) with superferric magnets (approx. 2.5 Tesla). We take as a premise that a sufficiently large piece of land is available for the accelerator (see paper on Site and Tunnel), that is, one is not limited by the radius of the tunnel. The word superferric has been interpreted to mean a super conducting magnet where the coils are used principally to drive the field in the steel. We also add the constraint of simplicity and keep the coil shaped in a rectangle with no more than a few turns.

Numerical experiments modeling the Rayleigh Taylor instability are carried out using a two-dimensional incompressible Eulerian hydrodynamic code VFTS. The method of integrating the Navier-Stokes equations including the viscous terms is similar to that described in Kim and Moin, except that Lagrange particles have been added and provision for body forces is given. The Eulerian method is 2nd order accurate in both space and time, and the Poisson equation for the effective pressure field is solved exactly at each time step using a cyclic reduction method. 3 refs., 3 figs.

The objective of this contract is to extend and optimize UOP's single-stage slurry-catalyzed co-processing scheme. Particular emphasis is given to defining and improving catalyst utilization and costs, evaluating alternative and disposable slurry-catalyst systems, and improving catalyst recycle and recovery techniques. The work during this quarter involved a series of temperature studies with different concentrations of Mo slurry catalyst. The results of bench-scale Runs 26 and 27 are discussed in the following report. 25 figs.

Powerful and quite general arguments suggest that N = 1 supergravity, and in particular the superstring-inspired no-scale models, may describe the physics of the four-dimensional vacuum at energy densities below the Planck scale. These models are not renormalizable, since they arise as effective theories after the large masses have been integrated out of the fundamental theory; thus, they have divergences in their loop amplitudes that must be regulated by imposing a cutoff. Before physics at experimental energies can be extracted from these models, the true vacuum state or states must be identified: at tree level, the ground states of the effective theories are highly degenerate. Radiative corrections at the one-loop level have been shown to break the degeneracy sufficiently to identify the states of vanishing vacuum energy. As the concluding step in a program to calculate these corrections within a self-consistent cutoff prescription, all fermionic one-loop divergent corrections to the scalar effective potential are evaluated. (The corresponding bosonic contributions have been found elsewhere.) The total effective scalar Lagrange density for N = 1 supergravity is written down, and comments are made about cancellations between the fermionic and bosonic loops. Finally, the result is specialized to a toy no-scale model with …

As a part of the five year budget study requested by HOO-AEC, a study of separations waste storage requirements for this period was made. This study took into consideration the variant estimates of amount of irradiated uranium to be processed, and the goals in the waste reduction research and development program. The conclusions of this study were at variance, to some extent, with prior studies. Interest has been expressed in publication of this study to permit independent assessment of its bases and assumptions.

An assessment is made of the technical and economical feasibility of converting municipal waste into useful and useable energy. The concept presented involves retrofitting an existing municipal incinerator with the systems and equipment necessary to produce process steam and electric power. The concept is economically attractive since the cost of necessary waste heat recovery equipment is usually a comparatively small percentage of the cost of the original incinerator installation. Technical data obtained from presently operating incinerators designed specifically for generating energy, documents the technical feasibility and stipulates certain design constraints. The investigation includes a cost summary; description of process and facilities; conceptual design; economic analysis; derivation of costs; itemized estimated costs; design and construction schedule; and some drawings.

The purpose of this document is to set forth the Program Plan for the Functional Analysis and Thermal-Hydraulics (FA TH) Program (herein after referred to as the [open quotes]Program[close quotes]) for the 5 year period covering fiscal years 1992 thru 1996. Specifically, the actions planned by the Safety Analysis Group (SAG) of the Reactor Safety Research Section within SRTC will be identified, defined, and a schedule and resource projection presented. This document will be used by the Reactor Safety Research Section management as the baseline definition for the Program's scope, schedule and cost. Annual budget and staffing requests will be submitted based on this approved baseline. Status reporting and progress monitoring will be performed against this approved baseline. This Program plan will be revised as needed to reflect the changes that come about due to Program redirection. The Program's primary mission is to provide further assurance that the Savannah River Site K-Reactor is designed, modified, operated and maintained in a safe, cost-effective manner through application of functional analysis methodology and continued development of thermal hydraulic support capabilities. It is envisioned that the Program will continue throughout the operating life of K-Reactor and have a permanent staff of eight: one lead …
