Deposition of films under irradiation conditions at 900 deg F, using OMRE coolant containing 600 ppm Fe as ferrocene, was established. It was found that films deposited from OMRE coolant on steel surfaces, but not on stainless steel or Al under the same conditions. The roles of iron carbide and oxygen on film formation were studied. Iron oxide was converted to the percarbide. The formation of carbon monoxide in irradiations of Santowax in the presence of air or combined oxygen was demonstrated. Electron irradiation of biphenyl and the pure terphenyls was carried out, and the dimeric isomers produced were identified. Selectivity in radical formation or attack was indicated by the small number of possible isomers that were found. Small amounts of aliphatic compounds were also found. Pyrolysis data indicated that film thickness increased exponentially with temperature between 800 and 960 deg F. The formation rate was directly proportional to the ash content, and ferromagnetic particles tended to form films more rapidly than nonmagnetic particles. Heat transfer through the film was affected by the type of coolant used. All of the quaterphenyls, two quinquephenyls, and six hexaphenyls were prepared in quantity. The optimum concentrations of such stabilizers as 2-mercaptobenzothiazole and phenothiazine were found to be about 10 mole%, and of a stabilizer using elemental sulfur, about 0.7 mole %. Certain fractions from coal tar and cycle oils, from petroleum catalytic cracking were found to have stability, high-boiler yields, and gas production on the same order of magnitude as terphenyls, and to be cheaper than terphenyls. These fractions were found to consist of phenanthrene nuclei with methyl and other alkyl side chains. Catalyst screening, and the evaluation of cobalt molybdate catalysts, for the reclamation of high boilers were conducted. Kinetic studies were made to provide information concerning EOCR reactivity- initiated accidents. Static-physics computations were carried out to obtain information as to the effective multiplication constant and the maximum power density within the fuel units of the initial EOCR fuel loading. Corrosion of 6061 Al by Santowax R at 650 and 750 deg F was found to be negligible. The solubility curve for Santowax R in xylene was studied. Designs of technological and test loops for the EOCR were outlined. Operation testing of control rod and drive and various other EOCR systems was completed. (T.F.H.)
