Benchmarking WASP5 with data from the 1991 K-Reactor tritiated aqueous release incident

Description: The Savannah River Site (SRS) has upgraded its aqueous emergency response capability to model the transport of pollutants released from SRS facilities during normal operation or accidents through onsite streams to the Savannah River. The transport and dispersion modules from the US Environmental Protection Agency (EPA) WASP5 model were incorporated into the SRS emergency response system, called the Weather Information and Display (WIND) System. WASP5 is a water quality analysis program that sim… more

Compliance of the Waste Isolation Pilot Plant with 40 CFR 194.24(b)

Description: This paper presents aspects of DOE`s demonstration of compliance with the EPA regulation of the Waste Isolation Pilot Plant (WIPP). The WIPP, a geologic repository for transuranic (TRU) waste, is located 2150 feet below the ground surface in a bedded salt formation about 20 miles east of Carlsbad, NM. Performance of the WIPP as a repository requires that releases to the accessible environment not exceed the limits of the regulation 40 CFR Part 191(1) either when the WIPP is undisturbed, or if t… more

Degradation of transuranic waste drums in underground storage at the Hanford Site

Description: In situ inspections were performed on tarp-covered 55-gallon drums of transuranic (TRU) waste stored underground at the Hanford Site. These inspections were part of a task to characterize TRU drums for extent of corrosion degradation and uncertainty in TRU designation (inaccuracy in earlier assay determinations may have led to drums that actually were low-level waste to be termed TRU), and to attempt to correlate accuracy of existing records with actual drum contents. Two separate storage trenc… more

Arc View/Avenue: Coding styles and utility scripts for efficient development

Description: Effectiveness and efficiency of software development can be greatly increased by writing modularized code using informal (styles) and formal (standards) work approaches. Software development is about connecting pieces into a coherent whole. Thus consistent work approaches provide a structure that allows individuals and teams to minimize the time and thought put into making these connections. These investments in structure return even more benefits in the maintenance phase when old code has to b… more

Application of mid-infrared spectroscopy to the identification of materials and to the determination of surface coatings

Description: A small user friendly, light-weight, field hardened, computer controlled device for performing infrared spectroscopic analysis, with high sensitivity of trace contamination on surfaces, has recently been defined by Lockheed Martin Energy Systems, Inc. The National Aeronautics and Space Administration at Marshall Space Flight Center, Alabama (NASA/MSFC) initiated a development contract to field a production model of this device with Surface Optics Corporation, San Diego, California in order to c… more

Cost uncertainty for different levels of technology maturity

Description: It is difficult at best to apply a single methodology for estimating cost uncertainties related to technologies of differing maturity. While highly mature technologies may have significant performance and manufacturing cost data available, less well developed technologies may be defined in only conceptual terms. Regardless of the degree of technical maturity, often a cost estimate relating to application of the technology may be required to justify continued funding for development. Yet, a cost… more

LEU conversion status of US research reactors, September 1996

Description: This paper summarizes the conversion status of research and test reactors in the United States from the use of fuels containing highly- enriched uranium (HEU, greater than or equal to 20%) to the use of fuels containing low-enriched uranium (LEU, < 20%). Estimates of the uranium densities required for conversion are made for reactors with power levels greater than or equal to 1 MW that are not currently involved in the LEU conversion process.

Furfural-based polymers for the sealing of reactor vessels dumped in the Arctic Kara Sea

Description: Between 1965 and 1988, 16 naval reactor vessels were dumped in the Arctic Kara Sea. Six of the vessels contained spent nuclear fuel that had been damaged during accidents. In addition, a container holding {approximately} 60% of the damaged fuel from the No. 2 reactor of the atomic icebreaker Lenin was dumped in 1967. Before dumping, the vessels were filled with a solidification agent, Conservant F, in order to prevent direct contact between the seawater and the fuel and other activated componen… more

Imaging back scattered and near back scattered light in ignition scale plasmas

Description: Diagnostics have been developed and fielded at the Nova laser facility that image scattered light in the vicinity of the final laser focusing lens. The absolute calibration of optical components exposed to the target debris have been achieved by a combination of routine in situ calibration and maintenance. The scattering observed from plasmas relevant to ignition experiments indicates that light scattered just outside the lens can be larger than that collected by the lens, and is a significant … more

Neutron source strength monitors for ITER

Description: There are several goals for the neutron source strength monitor system for the International Thermonuclear Experimental Reactor (ITER). Desired is a stable, reliable, time-dependent neutron detection system which exhibits a wide dynamic range and broad energy response to incident neutrons while being insensitive to gamma rays and having low noise characteristics in a harsh reactor environment. This system should be able to absolutely calibrated in-situ using various neutron sources. An array of… more

Poynting vectors and electric field distributions in simple dielectric gratings

Description: The authors discuss, with illustrations drawn from the simple example of a dielectric grating under total internal reflection illumination, the use of electric field, energy density and Poynting vector as tools for understanding phenomena associated with dielectric gratings. The electric field has greatest direct observational interest, and exhibits patterns of nodes and antinodes that are both expected and intuitive. The energy density, though not directly linked with photoelectric response, h… more

Beamsplitting using self-imaging

Description: The production of a variable array of optical point sources from a single point source can be achieved through the self-imaging properties inherent in a rectangular waveguide. Two prototype devices, based upon this concept, were designed and constructed. The resulting output patterns are discussed along with future design considerations and applications.

Efficient transformations from geodetic to UTM coordinate systems

Description: The problem of efficiently performing transformations from geocentric to geodetic coordinates has been addressed at previous DIS (Distributed Interactive Simulation) workshops. This paper extends the work presented at the 14th DIS Workshop. As a consequence of the new algorithm for geocentric to geodetic coordinate conversion, a subsequent conversion to Universal Transverse Mercator coordinates is made considerably more efficient. No additional trigonometric or square root evaluations are requi… more
