Application of solar energy to industrial drying of soybeans: Phase III, performance evaluation. Final report

Description: A 15-month performance evaluation was conducted on a solar system designed and constructed to augment the industrial drying of soybeans at the Gold Kist, Inc., extraction plant in Decatur, Alabama. The plant employs three oil-fired, continuous-flow dryers of 3,000 bu/hr each. The solar system consists of 672 Solaron air collectors that temper the airflow into the existing dryers. Since the requirement for energy exceeds the peak solar system capacity, no storage is provided. The interface with … more

Evaluation of improved light water reactor core designs. Final progress report, September 1979. LWRCD-20

Description: The work conducted under this research project has developed information which supports in all respects the U.S. position evolved under the NASAP/INFCE programs with respect to the near and intermediate term potential for ore conservation in LWRs on the once-through fuel cycle. Moreover, in the even longer term, it has been confirmed that contention by Edlund and others that tight-pitch Pu/UO/sub 2/ PWR cores can achieve conversion ratios which may allow these reactors to provide a competitive … more

Program RECENT (version 79-1): reconstruction of energy-dependent neutron cross sections from resonance parameters in the ENDF/B format. [In FORTRAN IV for CDC-7600 and Cray-1]

Description: Program RECENT reconstructs energy-dependent neutron total, elastic, capture, and fission cross sections from a combination of resonance parameters and tabulated background cross sections in the ENDF/B format. Entire evaluations, not just cross sections, are written to the result file, which is in ENDF/B format. The output includes the original resonance parameters in a form that can be used in Doppler broadening and self-shielding calculations. A listing of the source deck is available on requ… more

Program SIGMA1 (version 79-1): Doppler broaden evaluated cross sections in the evaluated nuclear data file/version B (ENDF/B) format

Description: Program SIGMA1 Doppler-broadens evaluated cross sections in the ENDF/B format. The program requires that input cross sections be tabulated as linearly interpolable functions of energy in ENDF/B File 3; broadened cross sections, in this same form, replace the original values in the output tape. This report describes the methods used in the code and serves as a user's guide. A listing of the source deck is available on request.

Radioecology of Natural Systems. Final Report, May 1, 1962-October 31, 1979

Description: This is the final report to the US Department of Energy and its predecessors on Contract EY-76-S-02-1156 with Colorado State University. During the first five years of the program, investigations were focused on the accumulation of fallout radionuclides in a well-studied mule deer population in north-central Colorado. In 1967, the scope of the program was enlarged to include studies on radionuclide behavior in mountain lake ecosystems, radiation effects on a shortgrass plains ecosystem, and the… more

Power-law thermal model for blackbody sources

Description: The spectral radiant emittance W/sub E/ from a blackbody at a temperature kT for photons at energies E above the spectral peak (2.82144 kT) varies as (kT)/sup E/kT/. This power-law temperature dependence, an approximation of Planck's radiation law, may have applications for measuring the emissivity of sources emitting in the soft x-ray region.

Analytical study of TATB preheating methods

Description: TATB (1,3,5 - triamino 2,4,6 - Trinitrobenzene) is a very stable explosive that is remarkably insensitive to severe impact and thermal environment. Experiments on its initiation and detonation characteristics have found it difficult to initiate under the energy transfer of thin flyer plates accelerated by electrically exploded metal foils. Figure 1 shows the propagation of a detonation front in such an experiment. Generally, the detonation waves are confined in the region directly in front of t… more

Corrosion of delta plutonium by synthetic sea water

Description: Tests have been performed to determine the corrosive nature of sea water on delta plutonium at 25/sup 0/C. Corrosion rates were determined by measuring the time dependence of mass loss at constant pressure and the time dependence of hydrogen evolution in a sealed vessel. Test coupons were completely immersed in a standard solution of synthetic sea water for periods ranging from 1 hour to 144 hours. Weight loss measurements show that delta plutonium corrodes at an average rate of 5.01 mg/(cm/sup… more

Energy sensitivity and variability analysis of Populus hybrid short-rotation plantations in northeastern United States. Final report

Description: Production of biomass by corn-like plantations has been demonstrated by a number of researchers. These forest analogs of agronomic cropping systems have the potential to yield substantially more biomass per unit area than traditional forests.
