EFFECTIVE CUTOFF ENERGIES FOR B, Cd, Gd, AND Sm FILTERS

Description: Effective energy cutoffs have been calculated on an IBM7090 computer for Cd, Gd, Sm, and B filters as functions of filter geometry, the ratio of Maxwellian to epithermal flux (assumed to be 1/E), the lower energy limit of the 1/E flux, the energy corresponding to the Maxwellian most probable (modal) velocity and filter thickness. The geometrical configurations were spherical (which on the assumptions madc is equivalent to a beam flux case), cylindrical and slab. By the use of two or three diffe… more

Modified horizontal solar collector for low temperature grain drying

Description: The project consisted of constructing a horizontal solar collector with a small amount of rock storage integrated into the collector air stream. The collected energy was used to dry corn in a 6000 bushel low-temperature drying facility. The collector proved to be economically feasible to build and collected sufficient energy to show a reasonable return on the investment.

Fluidized bed incineration system for U. S. Department of Energy defense waste. Status report, July--December 1976. [Defense waste]

Description: A fluidized-bed incineration facility has been designed for installation at the Rocky Flats Plant. The purpose is to develop and demonstrate the process for the combustion of transuranic waste. The unit capacity will be about 82 kg/hr of combustible waste. The combustion process will utilize in situ neutralization of acid gases generated in the process. The equipment design is based on data generated on a pilot scale unit and represents a scale-up factor of nine. Title II engineering is complet… more

Temperature Coefficients of the Reactivity Measurement Facility

Description: The temperature coefficient of the Reactivity Measurement Facility was found to be 49 plus or minus 1 mu k/ deg C (1 mu k = 10/sup -6/ DELTA k/k) in the range 15.4 to l7.8 deg C. The change in the net reactivity of a standard sample was --0.48 plus or minus 0.02, --0.66 plus or minus 0.03, and --0.78 plus or minus 0.02 mu k/ deg C in three measuring positions. These low values generally make temperature corrections insignificant. The above results are compared with previous determined values. T… more

Applications of Micellar Enzymology to Clean Coal Technology. [Laccase]

Description: This project is designed to develop methods for pre-combustion coal remediation by implementing recent advances in enzyme biochemistry. The novel approach of this study is incorporation of hydrophilic oxidative enzymes in reverse micelles in an organic solvent. Enzymes from commercial sources or microbial extracts are being investigated for their capacity to remove organic sulfur from coal by oxidation of the sulfur groups, splitting of C-S bonds and loss of sulfur as sulfuric acid. Dibenzothio… more
