SCTI chemical leak detection test plan (open access)

SCTI chemical leak detection test plan

Tests will be conducted on the CRBRP prototype steam generator at SCTI to determine the effects of steam generator geometry on the response of the CRBRP chemical leak detection system to small water-to-sodium leaks in various regions of the steam generator. Specifically, small injections of hydrogen gas (simulating water leaks) will be made near the two tubesheets, and the effective transport times to the main stream exit and vent line hydrogen meters will be measured. The magnitude and time characteristics of the meters' response will also be measured. This information will be used by the Small Leak Protection Base Program (SG027) for improved predictions of meter response times and leak detection sensitivity.

Equity Oil Company BX in situ oil shale project, Piceance Basin, Colorado. Environmental quarter report, March 1-May 31, 1981

This report has been organized into three sections for ease of review. Section A - Air Resources covers data collected by the 100-foot tower between September and December 1980. Section B - Water Resources covers data collected since the last Quarterly Report. Section C - Aquatic Biology covers data collected since January 1981. Laboratory analysis results of all water samples show no significant changes from previous sample have occurred. The alluvial wells did exhibit slightly higher concentrations of phenols. Presently no baseline record exists for these wells to establish the normal levels of phenols in the alluvial ground water. Laboratory analysis of all sampling locations are presented in Appendix B. Aquatic biology covers data collected during the initial two aquatic biology field sampling trips of 1981. Benthic invertebrates, periphyton algae, and a fishery survey was conducted. Stream observations indicate that the stream habitat has remained unchanged since the August 1980 field visit. (ATT)

Conservative Differencing of the Electron Fokker-Planck Transport Equation (open access)

Conservative Differencing of the Electron Fokker-Planck Transport Equation

We need to extend the applicability and improve the accuracy of kinetic electron transport codes. In this paper, special attention is given to modelling of e-e collisions, including the dominant contributions arising from anisotropy. The electric field and spatial gradient terms are also considered. I construct finite-difference analogues to the Fokker-Planck integral-differential collision operator, which conserve the particle number, momentum and energy integrals (sums) regardless of the coarseness of the velocity zoning. Such properties are usually desirable, but are especially useful, for example, when there are spatial regions and/or time intervals in which the plasma is cool, so that the collision operator acts rapidly and the velocity distribution is poorly resolved, yet it is crucial that gross conservation properties be respected in hydro-transport applications, such as in the LASNEX code. Some points are raised concerning spatial differencing and time integration.

Study of static reactive power compensators for high-voltage power systems. Final report, May 12, 1981 (open access)

Study of static reactive power compensators for high-voltage power systems. Final report, May 12, 1981

A general study of the application of static VAR compensators (SVC's) to high-voltage transmission systems has been performed. Considerable emphasis has been placed on improvements to synchronous stability, and it is shown that SVC's can provide significant benefits in terms of damping for unstable modes of oscillation and increases in transient stability limits. This report includes descriptions of static VAR compensators, technical and economic comparisons of different compensators, compensator models for system studies, comprehensive study procedures, study results for two small-scale systems, and guidelines for SVC application.

X-ray backlighting sources of 4 to 10 keV for laser-fusion targets (open access)

X-ray backlighting sources of 4 to 10 keV for laser-fusion targets

High-intensity, short-duration x-ray pulses are necessary to diagnose the compression of laser film targets. Present target designs are such that backlighting sources ranging from a few thousand electron volts to 100 keV will be necessary. The desired source durations range from a few tens of picoseconds for flash radiography to several nanoseconds for streaked backlighting, and the source occurrence must be tightly synchronized to that of the target-irradiating laser pulse. For the latter reason, a laser-induced x-ray pulse is preferred. An initial study of the K lines of Ti, Ni, and Zn as possible backlighting sources was conducted. The conversion efficiency of laser light into line radiation was obtained as a function of laser intensity, pulse length, and wavelength. A threshold laser intensity for x-ray line production was identified. Information was obtained on the size and duration of the x-ray emission source, in relation to laser parameters. The experimental results, and their impact on backlighting capability for high-density laser function targets, are discussed.
