Description: 7 9 7 D 8 8 9 9 7 7 ; 8 < fuel-reprocessing plant using pyrometallurgical procedures is being designed and constructed as part of the Experimental Breeder Reactor No. 2 project. Cable samples sealed with Temporell No. 741 were irradiated to 3.0 x lO/sup 9/ rad. Tests of the absorber-type fume trap were successful. Preparations were continued for high- activitylevel demonstrations of the melt-refining process for EBR-2 core fuel. An attractive and efficient procedure for removing uranium skull material from a melt-refining crucible is to convent it to free-flowing oxide powder by oxidation with a dilute oxygen- argon mixture at 700 to 800 deg C. Two complete runs were made for both demonstrating and pin-pointing difficulties in the drag-out or skullreclamation process. Investigation of the reduction of uranium oxides by liquid magnesium alloys was continued. Two runs were made to demonstrate recovery of plutonium from a magnesium solution by distillation of the magnesium. Operation of a mild steel corrosion loop for circulating a U-Mg- Cd alloy at 550 deg C was terminated after 4800 hr of trouble-free operation. The solubility of titanium in liquid cadmium was found to vary between 0.047 at.% at 449 deg C to 0.15 at. % at 651 deg C. The solubility of uranium in liquid lead over the temperature range from 415 to 802 deg C is given. The solubility of uranium in cadmium-magnesium solutions containing up to 72 wt.% Mg at 6l0 deg C was found to decrease smoothly from about 2 wt.% in pure cadmium to about 0.002% in72 wt.% Mg. The partition coefficients of a number of representative fissile and fission product elements between the immiscible liquids aluminum and cadmium at 680 to 688 deg C were measured. The heat of combustion of tungsten disulfide in oxygen was determined to ...

Description: The fuel value of U/sup 233/ was calculated for five thermal reactors (Dresden. Yankee, Carolinas-Vlrginia, Hallam, GCR-II). Relative to a U/sup 235/ value of per gram, pure U/sup 233/ had a value that varied from .2 to .2 per gram. U/sup 233/ contained in once- and twice-recycle uranium from an initial U/sup 233/-Th cycle had a value slightly in excess of the value of pure U/ sup 233.. The value of U/sup 233/ in recycle uranium from an initial U/sup 235/- Th cycle was less than that for pure U/sup 233/ and decreased with each succeeding cycle. (auth)

Description: The Zircaloy-clad fuels and the application of the Zirflex Process for dissolution are discussed. Zirflex chemical flowsheets are presented as developed by pilot plant operatlons. The Zirflex Process is applicable to the reprocessing of fuels from the Dresden Reactor and the PWR Reactor. Other applications of the process are the Plutonium Recycle Test Reactor fuels and the New Production Reactor fuels, possible fuels from the Experimental Breeder Reactor; NPD-2 fuels; and fuels from Carolina-Virginia Nuclear Power Associates Reactor.

Form, Style, Function and Rhetoric in Gottlob Harrer's Sinfonias: A Case Study in the Early History of the Symphony

Description: Gottlob Harrer (1703-1755) composed at least twenty-seven sinfonias for his patron Count Heinrich von Bruhl in Dresden from 1731-1747, placing them among the earliest concert symphonies written. Harrer's mostly autograph sinfonia manuscripts are significant documents that provide us with a more thorough understanding of musical activities in and around Dresden. Several of the works indicate topical references, including dance, march, and hunt allusions, that comment on the Dresden social occasions for which Harrer composed these works. Harrer mixes topical references with other gestures in several of his sinfonias to create what I believe is an unrecognized affective language functioning in instrumental works of the time. An examination of the topical allusions in Harrer's works solidifies their connection to the social milieu for which he wrote them, and therefore better defines the genre of the concert sinfonia of the time. The first part of this study of Harrer's sinfonias addresses evidence about the composer, his patron, Dresden society, and the circumstances surrounding the first performances of several works, musical evidence of the composer's stylistic and formal approach to the genre, and the rhetorical meaning of topical gestures in the scores in ways not yet explored. In this dissertation, I demonstrate that the stylistic and formal characteristics of Harrer's sinfonias were often influenced by the function and context of their premieres. Part Two of the dissertation provides transcriptions of Harrer's sinfonias, making them available for performance and further study in the hope that such a holistic approach will enrich our appreciation of musical life in Dresden in the 1730s.
