The Half-Life and Gamma Ray Abundance of Cs-137

Description: The nuclide Cs-137 is a fission product commonly used for measurement of uranium burnup in irradiated uranium fuel by the fission product to uranium ratio method. In the application of this method, the largest single error introduced in the measurement of burnup is the uncertainty in the half-life of Cs-137. Because of the uncertainty in this value and its importance in nuclear fuel burnup analysis, a reinvestigation was undertaken to obtain a more accurate value using the mass spectrometric me… more

Resonance Integral Calculations for Evaluation of Doppler Coefficients: The Rapture Code

Description: A code (RAPTURE) was programmed for the Philco TRANSAC 2000 computer to perform calculations needed for the evaluation of Doppler Coefficients in fast reactors with degraded neuron spectra. This code computes resonance integrals, averages them over resonance parameter distributions, and computes fission and capture cross sections as a function of fuel temperature and of potential scattering cross section per absorber isotope.

On the Synergistic Effect in Solvent Extraction

Description: The studies of Irving and Edgington, and Healy on the synergistic effects of tributyl phosphate (TBP) and tri-n-octylphosphine oxide (TOPO) on the solvent extraction of thorium and other metals by thenoyltrifluoroacetone (TTA) are discussed. It is shown that the synergistic effect is a result of addition reactions as well as replacement reactions and is not a function of the metal being extracted. A compilation of equilibrium constants describing the synergistic effect of TBP and TOPO on TTA … more

Color Production From Energetic Ions Impinging On Metals

Description: It has been observed that energetic gaseous ions mark their region of impingement on certain metals in color. Under identical conditions of bombardment, multicharged ions of the same gas mark their impact areas with different colors. The colors are sensitive to the type and energy of the ion as well as to the metal bombarded. These colors may result from reflections from thin films formed by reactions at the target. Because the colors indicate that thicker films are produced with increased ion … more

Investigations of Radioactive Fuel-Bearing Glasses

Description: "A series of high urania-content glasses were fiberized and examined for high-temperature strength properties. One glass, RX360 containing 60% U/sub 3/O/ sub 8/ by weight, had better high-temperature tensile properties than any glass previously reported. It was observed that many of the glasses studied separated into immiscible phases and that the fiberizable glass phase had lower U/sub 3/O/ sub 8/ content than the base compositions. A physical analysis of crystal structures of the devitrificat… more

Diffusion of Iron, Cobalt, and Nickel in Gold, Report No. 5

Description: "The diffusivities of Fe, Co, and Al in otherwise pure Au were determined by a residual activity technique. It was found that the frequency factors and activation energies of the transition elements into Au are normal relative to the values for Au self-diffusion, and suggest that lattice diffusion is operative, in contrast to the corresponding situation for the diffusion of these elements in Al. This difference in behavior is explained in terms of the marked difference in solid solubilities in … more

Diffusion in Cobalt-Nickel Alloys, Report No. 4

Description: The self-diffusivities of Co60 and Ni63 in cobalt--nickel solid solutions exhibit a greater activation energy below the Curie temperature (T/sub c/) than above. Values of DELTA Q = Q (ferromagnetic) -- Q (paramagnetic) are approximately equal to RT/sub c/. This observation is interpreted to indicate that the increment in activation energy arises from an increase in the formation energy of a vacancy in the ferromagnetic lattice, with the additional binding energy arising from the interaction of … more

On the Generalized Overrelaxation Method for Operator Equations

Description: "In Householder, using Weissinger's identity , obtained the necessary and sufficient conditions for the c onvergence of the Seidel method for the solution of finite matrix equations of the form (D-S-S*-F)u = f. The same coniditions were also obtained by Krein and Prozorovakaya for an analog of the Seidel method for the operator equations of the form (D+S+S*)u = f in a Hilbert space. The purpose of this article is to extend the result of the above authors to the generalized overrelaxation iter… more

Cosmogenic Carbon-14 and Chlorine-36 in Meteorites

Description: In 1947 Bauer, and later independently Huntley (1948), pointed out that the helium content of iron meteorites as measured by Paneth and coworkers could be accounted for by the accumulation through cosmic-ray production rather then the decay of uranium and thorium. Bauer (1947) also predicted that the meteroitic helium should contain a significant proportion of He3. I was realized that by studying the effects of cosmic radiation on meteorites much could be learned about the history of meteorite… more

Refractory Metals as Alkali Liquid Metal Containment Materials

Description: Abstract. Refractory metals and their alloys are good container materials for alkali metal coolants. Thermodynamics of interaction with contaminants have been correlated with experimental test and show the need for high purity materials. Structural metal solubility data to 1600F can be used to correlate and predict engineering systems.

The Microbiology of Heavy Water in the HIFAR Reactor

Description: The high flux research reactor HIFAR contains ten tons of heavy water which acts as moderator and primary coolant. Over an eighteen months period regular microbiological examinations have been carried out on samples of heavy water taken from various parts of the circuit. The heavy water circuit provides an interesting opportunity for the study of microorganisms because of the high isotopic purity (greater than 99.6 per cent.), and the high chemical purity of the heavy water in the reactor.

Design of Concentric Tubular Reactor Fuel Elements for Uniform Coolant Conditions

Description: Concentric tubular reactor fuel element geometries to give equal coolant outlet temperatures are presented. Oscillations from tube to tube in thickness and temperatures generally occur but it is possible to eliminate them by choice of the centre element. This may be a fuel rod or a non-heat—producing rod with or without a surrounding annulus of fuel. The geometries and temperatures are dependent on the voidage and on a non-dimensional parameter equivalent to a Biot number based on the channel e… more

Reactions of Preoxidized Beryllium Powder in Moist Carbon Dioxide

Description: Breakaway corrosion of Be in moist CO2 can be avoided if the Be is fabricated using preoxidized powder. The powder is preoxidized by heating in dry O/sub 2/. Preoxidation of Be powder was measured as a function of temperature and time of heating in O/sub 2/. The subsequent reactions of the preoxidized powder in moist CO/sub 2/ at 700 deg C were studied and the effect of increasing amounts of added oxide was measured. A model is proposed to explain the inhibition of corrosion by added oxide. (au… more

Electrical Resistivity of Rare-Earth Alloys

Description: From abstract: "Resistivities of solid solution alloys in the systems Gd-Lu, Tb-Lu, Gd-Er, and Y-Lu were measured from 4.2-320°K to determine the behavior of the resistivity in alloy systems with magnetic phenomena arising from localized magnetic moments. A large contribution to the residual resistivity is caused by the random distribution of these localized moments through the lattice. An analysis of the lattice resistivity of the metals shows large variations across the heavy rare-earth serie… more
