Significant progress toward the development of a solar energy storage system based on the norbornadiene-quadricyclene interconversion has been achieved during the past year. New sensitizers and catalysts have been discovered and conditions found where single cycles of the photosensitization step and the catalytic reversion step appear to be quantitative. Both sensitizers and catalysts have been successfully incorporated onto insoluble polymeric supports. The long term stability of these components is currently being tested using a recently constructed prototype device designed for multiple recycling experiments. Investigations are also underway on design modifications which will allow incorporation of the norbornadiene-quadricyclene system into currently available state-of-the-art solar collectors.

The emphasis of work during this past quarter has been on improvement of the performance of immobilized photosensitizers. Prolonged use of Polymer N in the recycling prototype has resulted in gradual deterioration of the behavior of this photosensitizer. Furthermore the opacity of the beads results in an inherent 20% loss in efficiency apparently through light reflection. In an attempt to improve the characteristics with respect to these points considerable effort was devoted in the synthetic grafting of sensitizer chromophores to glass surfaces. Some success has already been achieved, and the first successful silica-grafted photosensitizer is reported. Experience with the polystyrene grafted sensitizers, such as polymer N, has shown that details concerning the synthetic pathway (such as percent loading, types of site-site interactions, particle size and synthetic sequence) markedly influence the performance. Clearly, enhanced characteristics can be expected with systematic refinements. Preliminary results on both organic and inorganic systems are described.

Research on polymer organic sensitizers and polymer inorganic sensitizers for the conversion of norbornadiene to quadricyclene for thermochemical storage of solar heat is described. Also, research on the catalysis of the conversion of quadricyclane to norbornadiene is described. Polymer-anchored cobalt(II) porphyrin catalysts, polymer-anchored palladium(II) phosphine catalysts, and triphenylcyclopropenyl nickel complexes as catalysts were studied, and results are discussed.

Bench-scale pilot plant studies were conducted to evaluate chemical coagulation and ion exchange for decontamination of 2724-W laundry wastewater. Chemical coagulation is accomplished at pH 11 to avoid complexant problems and assure good transuranic radionuclide removals. Clinoptilolite is used to remove cesium and strontium. Results of the pilot plant studies are summarized as follows: Decontamination factors of 70 (strontium) and more than 100 (cesium) were achieved by chemical coagulation and ion exchange. Decontamination factors exceeding 90 were measured for europium by coagulation with a combination of ferric chloride, magnesium chloride, and calcium chloride added to the wastewater at pH 11. Coagulation with these three agents in the wastewater at pH 11 was more effective for turbidity removal than coagulation with lime. Addition of up to 1.7 lb of clinoptilolite fines per 1000 gallons of wastewater during coagulation did not substantially increase strontium and cesium removal. Filtration without chemical coagulation reduced suspended solids by only 25%. About 70% of the suspended solids remaining in the filtered wastewater were removed in the zeolite column causing plugging which could not be easily dislodged by backwashing. Plugging of the ion exchange columns by previously clarified wastewater required short periods of limited backwashing to relieve …

A method was developed for inference of core barrel motion from the following statistical descriptors: cross-power spectral density, autopower spectral density, and amplitude probability density. To quantify the core barrel motion in a typical pressurized water reactor (PWR), a scale factor was calculated in both one- and two-dimensional geometries using forward, variational, and perturbation methods of discrete ordinates neutron transport. A procedure for selection of the proper frequency band limits for the statistical descriptors was developed. It was found that although perturbation theory is adequate for the calculation of the scale factor, two-dimensional geometric effects are important enough to rule out the use of a one-dimensional approximation for all but the crudest calculations. It was also found that contributions of gamma rays can be ignored and that the results are relatively insensitive to the cross-section set employed. The proper frequency band for the statistical descriptors is conveniently determined from the coherence and phase information from two ex-core power range neutron monitors positioned diametrically across the reactor vessel. Core barrel motion can then be quantified from the integral of the band-limited cross-power spectral density of two diametrically opposed ex-core monitors or, if the coherence between the pair is greater than or …

Work on an existing multiple growth furnace has begun with the aim of achieving growth of 5, 2'' wide ribbons simultaneously at a rate of 3 in./min. The equipment and the initial experiments carried out are described. Also starting is a task aiming to bring the 5 ribbons under automatic control, equally using pre-existing equipment and designs. Furthermore, the effort to characterize the EFG (edge-defined film-fed growth) materials produced is increased and particular emphasis is placed on measuring and analyzing their solar cell performance. Data are presented on defect densities in various EFG grown ribbons. It is demonstrated that the diffusion length is larger under AM1 than under ''dark'' conditions, and results are shown on electrical inhomogeneities in the ribbon cells. Many of these results are interpreted in terms of defect-impurity interactions which are believed to be the main impediment to better solar cell performance at the present time. However, data are reported on an EFG solar cell of 12% AM1 efficiency, and on several 1'' x 4'' EFG cells of efficiencies between 9 and 11%. In the single ribbon resistance heated crystal growth station, a major effort is made to identify the sources of impurities introduced during growth by …

The rotating disk electrode system designed to obtain a complete set of experimental data (electrode polarization and coulombic efficiency) for electrode materials is described. Preliminary experiments with the rotating disk Ca electrode yielded polarization curves for Ca dissolution. Open-circuit potentials for the disk electrodes were essentially indistinguishable from the computer interelectrode IR drop. Limiting currents were obtained in NaOH--NaCl mixtures. Tafel-like behavior was found for Ni(O/sub 2/). Cooling curves were obtained in vacuo for KI--LiI eutectic composition. The following tabulations are given: cell voltage losses in the recycling process; critical data used in the calculation of energy conversion degradation of the system due to transport of Li and LiOH . H/sub 2/O between fixed-site recycling centers and refueling stations; and a breakdown of energy losses associated with Li production, battery discharge, and materials transport. 3 figures, 3 tables.
