Analysis of the Risk of Transporting Uranium Ore Concentrates by Truck

Description: This report evaluates the risks involved with shipping uranium ore concentrates by truck in an attempt to provide some perspective on the system safety issues. The basic probabilistic risk evaluation methodology used in this study is similar to that employed by Pacific Northwest Laboratory (PNL) in a series of risk analyses on the transportation of potentially hazardous energy materials. The risk model has been constructed as a series of separate analysis steps to allow the system risk to be re… more

Assessment of precision gamma scanning for inspecting LWR fuel rods. Final report

Description: Reconstruction of the radial two-dimensional distributions of fission products using projections obtained by nondestructive gamma scanning was evaluated. The filtered backprojection algorithm provided the best reconstruction for simulated gamma-ray sources, as well as for actual irradiated fuel material. Both a low-burnup (11.5 GWd/tU) light-water reactor fuel rod and a high-burnup (179.1 GWd/tU) fast breeder reactor fuel rod were examined using this technique.

Assessment of the computer code COBRA/CFTL

Description: The COBRA/CFTL code has been developed by Oak Ridge National Laboratory (ORNL) for thermal-hydraulic analysis of simulated gas-cooled fast breeder reactor (GCFR) core assemblies to be tested in the core flow test loop (CFTL). The COBRA/CFTL code was obtained by modifying the General Atomic code COBRA*GCFR. This report discusses these modifications, compares the two code results for three cases which represent conditions from fully rough turbulent flow to laminar flow. Case 1 represented fully r… more

Assessment of the Geothermal Potential of Southwestern New Mexico. (Final Report: 7/1/78 - 4/30/80)

Description: Results are reported of geologic mapping of geothermal anomalies in the Gila Hot Springs KGRA/Mimbres Hot Springs area, Grant County. They suggest that both hot-spring occurrences are structurally controlled by the intersection of a major Basin and Range fault and the disturbed margin of an ash-flow tuff cauldron. Hydrothermal alteration in both areas is related to mid-Tertiary volcanism, not to modern hot springs. At Gila Hot Springs, the geothermal aquifer is a zone at the contact between the… more

Automated Fresnel lens tester system

Description: An automated data collection system controlled by a desktop computer has been developed for testing Fresnel concentrators (lenses) intended for solar energy applications. The system maps the two-dimensional irradiance pattern (image) formed in a plane parallel to the lens, whereas the lens and detector assembly track the sun. A point detector silicon diode (0.5-mm-dia active area) measures the irradiance at each point of an operator-defined rectilinear grid of data positions. Comparison with a … more

Ballooning stability in toroidal devices

Description: The marginal stability condition of ballooning instabilities for toroidal confinement devices is derived for low critical stability ..beta.. (..beta.. less than or equal to 10%). The stability condition derived here should be applicable to EBT and multipoles as well as tokamaks and stellarators. For EBT and multipoles a more compact expression for the stability condition is possible and is given here in the appendix.

CARBON-14 IN SAGEBRUSH ON THE HANFORD SITE AND VICINITY

Description: The purpose of this study was to estimate the levels of {sup 14}C in sagebrush wood from plants growing on the Hanford Site and vicinity and to determine if these levels could be attributed to past and present operations at Hanford. Mature sagebrush plants were collected at one onsite and two offsite locations and analyzed for {sup 14}C. The offsite samples were collected both 60 km upwind and 26 km downwind from fuel reprocessing facilities on the Hanford Site. The results from these samples s… more

The inward transport time for /sup 3/He puffed at the edge plasma was 10 ..-->.. 30 msec. The decay time of the central /sup 3/He density increased with electron density, varying from 0.3 sec to greater than 1.0 sec over the density range of (1 ..-->.. 5) x 10/sup 13/ cm/sup -3/.

Characterization of geothermal solid wastes

Description: The compositions of 5 major types of geothermal wastes have been determined, and samples have been subjected to EPA recommended extraction tests to determine if they contain toxic metals that would classify the wastes as hazardous. Of the samples tested, the extracts of geothermal brines clearly contain levels of As, Ba and Pb exceeding the maximum allowed concentrations that characterize wastes as toxic. Only one other waste type, geothermal scale, exhibited EP toxicity. Pb was found in the ex… more

CO/sub 2/-laser ignition of DAPP targets

Description: A pulse derived by shuttering a CO/sub 2/ laser operating in the cw mode has been used to ignite a diallyl phthalate pyrotechnic (DAPP) material. Data from this work along with some data taken earlier, while operating the laser in the pulse mode, are presented. When operating in the cw mode, a pulse is mechanically chopped out of the beam and focussed onto the DAPP material. It was found that the shuttered cw mode of operation gives a more reproducible pulse and a more accurate determination of… more
