Analysis of Meteorological Data Obtained During Flight in a Supercooled Stratiform Cloud of High Liquid-Water Content (open access)

Analysis of Meteorological Data Obtained During Flight in a Supercooled Stratiform Cloud of High Liquid-Water Content

"Flight icing-rate data obtained in a dense and abnormally deep supercooled stratiform cloud system indicated the existence of liquid-water contents generally exceeding values in amount and extent previously reported over the midwestern sections of the United States. Additional information obtained during descent through a part of the cloud system indicated liquid-water contents that significantly exceeded theoretical values, especially near the middle of the cloud layer. The growth of cloud droplets to sizes that resulted in sedimentation from the upper portions of the cloud is considered to be a possible cause of the high water contents near the center of the cloud layer" (p. 1).

Reactions of Titanium With Water and Aqueous Solutions. Quarterly Report No. 1, (Report No. 2) for March 15-June 15, 1957

A reactor for investigation of the action of oxygenated water on Ti was constructed, which allows examination of these reactions under any conditions up to 300 deg C and 2000 psi, using either static or dynamic conditions of fiow. Rupture disks made of Ti foil 4 to 12 mils thick reacted violently with O/sub 2/ at any temperature between 30 to 300 deg C, if a fresh surface was exposed by breaking the disks. Such disks did not react with water containing up to 2000 ppm 0/sub 2/, even when a fresh surface was produced. Titanium foil of the same dimensions suspended in the reactor did not react with C2 at temperatures up to 300 deg C, as long as no fresh surface was produced mechanically. (auth)

Theoretical Studies of the Solidification of Uranium Castings (open access)

Theoretical Studies of the Solidification of Uranium Castings

The evaluation of factors involved in the production of sound uranium castings is the objective of a program of study now in progress. A mathematical model have been developed to calculate the time-temperature relationships in a cylinifical uranium casting during it solidification. Finite-difference equations are used, and the solution is obtained by use of a digital computer. Studies of the effects of such variables as the superheat, rate of pour, mold preheat, mold size, and others are possible, and their effect on casting soundness can be determined. Initial computed results demonstrate that this approach is feasible, and experiments are proposed to verify the method of analysis. The need for accurate values of the thermal properties of the casting and mold material is indicated. (auth)

Evaluation of Reactor Core Materials for a Gas-Cooled Reactor Experiment

From introduction: "On February 1, 1956, Batelle was awarded a contract by the Army Reactor Branch (ARB) to select, develop, and test core materials which could be used successfully in conducting a Gas Cooled Reactor Experiment (GCRE). The prime objective of the GCRE would be to evaluate small portable reactor systems for military application...The present report is concerned with the GCRE activities at Batelle during approximately the 7 months' period following the first report of this series, BMI-1133. It is primarily concerned with a detailed evaluation of the reference materials as well as of the impact of one material upon the other."

Evaluation of Reactor Core Materials for a Gas-Cooled Reactor Experiment (open access)

Evaluation of Reactor Core Materials for a Gas-Cooled Reactor Experiment

An evaluation of core materials for a gas-cooled reactor is being made. Work on the ZrH/sub n/ moderator has been confined to the high-hydrogen or delta- phase material. Methods for preparing sound hydride bodies of the highhydrogen composition have been developed. Both solid hydride and hydride powder compacts are being clad by a pressure-bonding technique. The hot hardness, tensile strength, thermal conductivity, thermal-expansion coefficient, and dissociation pressure of the delta-phase material are being determined. Control-material development was directed at rare-earth-oxide dispersions in Ni-chrome V or Co alloys. The reference fuel element is dispersedUO/sub 2/ in stainless steel. Studies include work on fabrication techniques and irradiation damage, and physical- and mechanical-property determinations. Several alternate fuels are being investigated. Gas-coolant studies involve N-metal and NH/sub 4/-metal reactions. Several additives to retard nitriding are being investigated. An in- pile-loop facility for testing reference materials is being constructed for operation in the Battelle Research Reactor. (auth)
