The Cold Pressing of Sinterable UO₂

Description: The intent of this work was to explore more fully the pressing of sinterable UO2 powders into cylindrical compacts in the hope that a more precise prediction of green density in terms of powder properties, pressure, and geometry could be evolved.

Gamma-Ray Spectrometry of Neutron-Deficient Isotopes: Annual Progress Report, March 1964

Description: From abstract: "The objective of this program is to produce a set of pulse-height spectra representing the response of a standard gamma-ray scintillation spectrometer to radiations emitted in the decay of neutron-deficient nuclides."

Low energy gamma-transitions in Pu{sup 238} and Pu{sup 240}

Description: We investigated electron and gamma spectra of mixtures of isotopes of curium. This was done on a beta spectrometer with double focusing at an angle of {pi}{radical}2 and on a scintillation gamma spectrometer with a 40 {times} 40 mm NAI(Tl) single crystal detector. The observed electron spectrum are interpolated and presented. Also, experimental results of the ratio of conversion at L and M subshells are presented and compared to theoretical values.

Dependence of the yield of the ({alpha},n) reaction on alpha particle energy

Description: Neutron yields for alpha particle reactions with beryllium, boron, carbon, magnesium, and oxygen are calculated. The dependence on energy of the incoming alpha particles is analyzed for yield. Calculations are varied for different sets of cross section data.

THORIUM-MOLYBDENUM PHASE DIAGRAM

Description: The phase diagram of the Th-- Mo alloy system has been determined to be of the eutectic type with a eutectoid reaction associated with the Th alpha-beta transformation. X-ray, thermal, electric resistance, and metallographic methods have established the eutectic point at 1380 plus or minus 10 deg C and 7.0 plus or minus 0.5 wt% Mo. A eutectoid reaction is proposed at 1358 plus or minus 5 deg C and less than 0.1 wt% Mo. No solubility of Th in Mo was detected at 1325 deg C. (auth)

PHASE ACCEPTANCE AND BUNCHING IN THE AGS LINAC. Internal Report

Description: Phase acceptance of the Alternating-Gradient Synchrotron Linear Accelerator is theoretically examined and found to agree well with an experimental determination of phase acceptance. Bunching in the AGS linac is also analyzed, the results indicating a satisfactory understanding of this process also. A double buncher that should be more efficient than the present single buncher is discussed, and space charge effects (as yet unobserved in bunching) are analyzed. (D.C.W.)

TRANSFERENCE NUMBERS AND ION ASSOCIATION IN PURE FUSED ALKALINE EARTH CHLORIDES

Description: The transference number of the chloride ion was determined in pure fused MgCl/sub 2/, CaCl/sub 2/, SrCl/sub 2/, and BaCl/sub 2/ utili zing radioactive chloride ions in a porous quartz membrane cell. On the basis of a two-step dissociation for these salts, MCl/sub 2/ in equilibrium MCl/sup +/ + Cl/sup -/ in equilibrium Ml/sup +/ + 2Cl/sup -/, the ext ent of the second dissociation was qualitatively predicted from a consideration of the relative mobilities of the ions.

EGCR EXPERIMENTAL LOOPS, PRELIMINARY DESIGN REPORT

Description: The EGCR was designed to accommodate up to four gascooled experimental loops plus several experimental fuel elements in the open core. Two of the loops will utilize 51/2-in.-O.D. stainless steel tubes passing through the core along an axis which is about 17 in. from the central axis of the core. The other two loops will utilize 91/2-in.-o.d. tubes about 68 in. from the central axis. Inherent safety in the design, facility design, primary loop design, auxiliary systems and equipment design, prim… more

Water Test Development of the Fuel Pump for the MSRE

Description: A vertical centrifugal sump-type pump utilizing commercially available impeller and volute designs was selected to circulate the fuel salt in the Molten Salt Reactor Experiment (MSRE). Tests were conducted in water to determine the adequacy of the pump design, to assist design of the prototype fuel pump, and to investigate the effectiveness of xenon removal with high velocity liquid jets contacting sweep gas in thc pump tank. Hydraulic head characteristics were within +1 to -3 ft of manufacture… more

X-ray, thermal, electrical resistance and metallographic methods have established the eutectic point at 1380 ± 10°C and 7.0 ± 0.5 wt % molybdenum. A eutectoid reaction is proposed at 1358 ± 5°C and less than 0.1 wt % molybdenum. No solubility of thorium in molybdenum was detected at 1325°C."
