Actual versus design performance of solar systems in the National Solar Data Network

Description: This report relates field measured performance to the designer predicted performance. The field measured data was collected by the National Solar Data Network (NSDN) over a period of six years. Data from 25 solar systems was selected from a data pool of some 170 solar systems. The scope of the project extends beyond merely presenting comparisons of data. There is an attempt to provide answers which will move the solar industry forward. As a result of some industry and research workshops, severa… more

Adequacy of radioiodine control and monitoring at nuclear fuels reprocessing plants

Description: The present backlog of irradiated reactor fuel leads to projections that no fuel out of the reactor less than 10 years need be reprocessed prior to the year 2000. The only radioiodine present in such aged fuel is /sup 129/I (half-life 1.6 x 10/sup 7/ y). The /sup 131/I initially present in the fuel decays to insignificance in the first few hundred days post-reactor. The /sup 129/I content of irradiated fuel is about 1 Ci per gigawatt-year of electricity generated (Ci/GW(e)-y). The US EPA has sp… more

Adjoint sensitivity analysis of a thermal hydraulic system undergoing phase change due to boiling transition. [BWR]

Description: Sensitivity analysis of practical problems can be performed systematically and very efficiently by using adjoint functions. In areas of interest to nuclear reactors, this efficiency has been amply demonstrated on several widely used codes for neutronics and/or thermal hydraulic calculations. Applications of the adjoint method of sensitivity analysis to models involving phase transitions, where non-differentiability occurs, do not seem to have been reported to date. The purpose of this paper is … more

Adjoint transport calculations for sensitivity analysis of the Hiroshima air-over-ground environment

Description: A major effort within the US Dose Reassessment Program is aimed at recalculating the transport of initial nuclear radiation in an air-over-ground environment. This paper is the first report of results from adjoint calculations in the Hiroshima air-over-ground environment. The calculations use a Hiroshima/Nagasaki multi-element ground, ENDF/B-V nuclear data, one-dimensional ANISN flux weighting for neutron and gamma cross sections, a source obtained by two-dimensional hydrodynamic and three-dime… more

Advanced coal liquefaction research. Quarterly technical progress report, July 1, 1983-September 30, 1983

Description: Work this quarter focused on staged liquefaction. The effect of residence time on conversion in single pass experiments was found to be quite different for the subbituminous Belle Ayr Mine and bituminous Illinois No. 6 coals studied. With bituminous coal, conversion to soluble material is quite high and the limit of conversion is approached in only a few minutes. With a subbituminous coal, however, conversion is much lower and the limit of conversion is approached much more slowly. Short contac… more

Advanced crystalline laser materials

Description: To guide the laser materials research and development effort, we have analyzed the scaling laws for zig-zag and flow-cooled disk amplifiers, defined materials figures of merit, and developed laser performance applications maps. Within this technical framework, we have embarked on an effort to synthesize, characterize, select, and develop new materials useful for a variety of robust laser applications.

Advanced direct coal liquefaction. Quarterly technical progress report No. 1, September-November 1983

Description: Wyoming subbituminous coal was liquefied using three different two-stage process configurations in bench-scale tests. These process configurations differed in the type of fractionated deashing resid being recycled to the individual stages. The objective of these runs was to determine whether, by recycle of specific resid streams to the thermal stage, the second stage catalyst life could be improved without detrimentally affecting distillate yield or hydrogen consumption. The results indicate th… more

Advanced direct coal liquefaction. Quarterly technical progress report No. 2, December 1983-February 1984

Description: Five Bench-Scale coal liquefaction runs were completed with Wyoming subbituminous coal in a two-stage process scheme. In this process scheme, LDAR, the lighter fraction of ash-free resid, was fed to the catalytic stage prior to its recycle to the thermal stage, whereas DAR, the heavy fraction of the deashed resid, was directly recycled to the thermal stage without any intermediate processing step. The results indicate that increasing coal space rate in the dissolver resulted in lower coal conve… more

Advanced research for the characterization of hydrogen donor solvents in two-stage liquefaction. Quarterly report, April 1, 1984-June 30, 1984

Description: Solvent-only reactions at SCT conditions in hydrogen were explored for each of the four blended solvents, ranging from 6.1 to 8.6 wt. % hydrogen content (nominally 6.1, 7.7, 7.4, 8.6). Generally, no loss of solvent to gas was measured, but small amounts of retrograde reactions (oil to preasphaltenes, asphaltenes, insolubles) were observed at both low and high severity. Insolubles were produced in solvent A (6.1% H) and consumed in solvent D (8.6% H). Ten hydrotreating and hydrocracking catalyst… more
