Fuel Elements Conference, Paris, November 18-23, 1957: Book 1, Sessions 1, 2, and 3

Description: Preface: The Fuel Elements Conference held in Paris, France, November 18 to 23, 1957, under the joint sponsorship of the U.S. Atomic Energy Commission and the French Commissarat à l'Energie Atomique (CEA), provided an intensive review of fuel-element fabrication practices and behavior of fuel elements under in-pile irradiation and when subjected to corrosive media.

Description of a Dropping Mercury Polaroscope

Description: Abstract: " The construction and operation of a dropping mercury polaroscope developed by Quentin A. Kerns is described herein. With this polaroscope a Heyrovsky polarogram is automatically produced on the screen of a cathode ray tube during the formation of each drop at the tip of a dropping mercury electrode, a change in the resistance of the cell operates to initiate the generation of a voltage wave to be applied to the cell during the formation of the next drop during a predetermined fractional portion of the average drop formation period."

Basic Radiation Damage Studies. Technical Progress Report, December 15, 1967-December 15, 1968

Description: In this investigation, there was an examining of the effect of different doping impurities on the annealing of lightly doped n-type Ge following electron irradiation at liquid helium temperature. The index of damage is the pulsed field (hot carrier) conductivity, measured with the specimen at 4.2 degrees in Kelvin.

TAGS-85/2N RTG Power for Viking Lander Capsule

Description: Results of studies performed by Isotopes, Inc., Nuclear Systems Division, to optimize and baseline a TAGS-85/2N RTG for the Viking Lander Capsule prime electrical power source are presented. These studies generally encompassed identifying the Viking RTG mission profile and design requirements, and establishing a baseline RTG design consistent with these requirements.

[Determining the Effect of Structure and Environment on the Radiation and Non-Radiation Probabilities in Metal Complexes]. 1968-69 Annual Technical Progress Report, June 16, 1968-June 15, 1969.

Description: This report addresses relaxation of 2^E states in Cr(III) complexes, trigonal splittings in Cr(C2O4)3^+3, low temperature Cr(III) spectra, 2^E splitting in tetragonal fields, doublet-doublet absorption from excited states of Cr(III) complexes, and polarization of electronic transitions in metal acetylacetonates.

Organic Coolant Reactor Program Quarterly Report, January 1-March 31, 1962

Description: The possible effects of a hydrogen atmosphere in reducing film deposition were studied in the large circulating loop and in rocking cell and pyrolytic capsule tests. At H/sub 2/ pressures of 200 to 400 psig no reduction in film weight deposited was observed in the loop tests, and in the pyrolytic tests film deposits were doubled. Heat conductivity of the films was much higher however. ln these high ash films the inorganic constituent was found to be alpha -Fe rather than the usual magnetite, which seems to account for the heat conductivity. Separation of benzene-insoluble material from high boiler and coolant was accomplished by centrifugation and by deposition on glass. The material was closely related to film formation. The nature of the inorganic and organic constituents of this material was examined in several analytical studies. Advances in the techniques of nuclear magnetic resonance, O/sub 2/ analysis, measurement of chromatograms, application of computers, and other methods were made. It was demonstrated by use of Fe5/sup 59/ that irradiated terphenyl under air attacks Fe rapidly and possibly the Fe is in solution as a chelate or other complex. It also was indicated by some tests that such a soluble form of Fe can figure in the formation of film and of the iron percarbide observed. The program of synthesis of pure samples of polyphenyls neared completion, and the attention was shifted to synthesis of new candidate coolants. Fused-ring structures, partially hydrog-enated, such as dihydrophenanthrene were made and proved of interest. Similar studies from the stabilizer investigation indicate the same thing. Other groups in which synthetic activity was initiated are the substituted triazines, pyridines, and other heterocyclic nonbenzenoid types. The industrial coolant candidates from petroleum and coal tar were found to be lacking in thermal stability above 700 deg F. Only the hydrodealkylated …
