Hydration-dehydration cycling of MgO--Mg(OH)/sub 2/ for application to solar heat storage systems

Description: A method for storing heat energy by utilizing reversible chemical reactions of inorganic oxides with water is under investigation at Atomics International. The system design requires a knowledge of rates of the dehydration and hydration reactions, and, in order that these rates be significant for practical applications, it must be shown that these rates are maintained as the material is cycled repeatedly through the anhydrous and hydrated condition. For solar heat storage operating on a daily c… more

Transpiration of helium and carbon monoxide through a multihundred watt, PICS filter. [Primary impact containment shell (PICS)]

Description: The transpiration of CO through the Multihundred Watt (MHW) filter can be described by Fick's first law or as a first order, reversible reaction. From Fick's first law, a ''diffusion'' coefficient of 7.8 x 10/sup -4/ cm.L/sec (L is the average path length through the filter) was determined. For the first order reversible reaction, a rate constant of 0.0058 hr/sup -1/ was obtained for both the forward and reverse reactions (they were assumed to be equal). This corresponds to a half-life of 120 h… more

Energy transfer mechanisms in photobiological reactions. Progress report, 1 August 1975--30 April 1976

Description: As in our earlier work on the sensitized photooxidation of substituted phenylalanines, ring substituents were found to have a marked effect on the photooxidation of uracil. This compound was selected as a typical pyrimidine for detailed studies of the mechanism of photooxidation of molecules of biological importance. The photooxidation of a series of 5-substituted uracils as sensitized by eosin Y, ruthenium bipyridyl, 3-methyl-lumiflavin and methylene blue was studied using oxygen electrode and… more

Future of nuclear power in the Northeast

Description: As of July 1975, there were 15 operable nuclear power plants in the Northeast, representing approximately 11 percent of the regional electric generating capability. Construction plans for the next two decades show a strong preference for nuclear units, there being 18 new units under construction and 33 additional units announced. Three projections (scenarios) covering the period from 1976 to 2000 are presented. The Base Case Nuclear Scenario assumes that the construction schedules as of August … more

Advanced electrooptic components for satellite/submarine optical communications systems

Description: Significant progress was made on identification and acquisition of optical components for an ultrahigh brightness weakly tunable blue-green beam generator. Limited performance validation of key system design concepts was achieved, and significant progress was made in improved optical design for more efficient generation of ultrahigh brightness, tunable blue-green radiation. These results are detailed.

Effects of whole-body. gamma. -irradiation on the biosynthesis of certain serum proteins. Final report, November 29, 1967--June 30, 1976. [Rats]

Description: Whole-body exposure of rats to ionizing radiations yielded an increased incorporation of labeled amino acids into serum albumin in in vivo studies suggesting a stimulation of biosynthesis. Actually this may have been caused by an elevated hepatic transport of labeled amino acids (see below). A suppressed biosynthesis of albumin was observed when the experiments were performed in vitro using liver microsomes. Impaired biosynthesis appeared to be caused by a reduced mRNA production. Irradiation s… more

Tritium waste control project progress report, October--December 1975. [Tritiated waste decontamination by molecular excitation; catalytic exchange detritiation studies; development of shipping containers for tritiated liquid waste]

Description: In the tritiated liquid waste decontamination by molecular excitation studies, further calculations were performed on the hydrogen atom-water exchange reactions. Assembly and testing of the cell to be used for the measurement of the HTO IR spectrum were completed. As a result of findings from trial loadings using HD as a surrogate for HT in the oxidation system, it is believed that larger quantities of HTO will be required to obtain the desired ir spectrum. This appears to be a result of a sign… more

HTGR accident initiation and progression analysis status report. Volume VII. Occupational radiation exposures from gas-borne and plateout activities

Description: As a part of the Accident Initiation and Progression Analysis (AIPA) program, calculations were performed of the occupational dose rates and man-rem exposures from gas-borne and plateout activities in a reference 3000-MW(t) HTGR plant. The study included a preliminary survey to determine the most important contributors by operation or radiation source to the man-rem exposures. This survey was followed by detailed calculations for the most important cases. Median and 95 percent-confidence-level … more

Geothermal energy in California: Status report

Description: The potential for electric energy from geothermal resources in California is currently estimated to be equivalent to the output from 14 to 21 large (1000 MW) central station power plants. In addition, since over 30 California cities are located near potential geothermal resources, the non-electric applications of geothermal heat (industrial, agriculture, space heating, etc.) could be enormous. Therefore, the full-scale utilization of geothermal resources would have a major impact upon the energ… more
