100 Area Process Water Pressure Decay Test Program: Part 1

Description: The increase in process tube outlet water temperature to 90{degree}C resulted in increased emergency water flow requirements as indicated by recently approved curves which establish minimum crossheader pressure requirements for the first three minutes following an electrical power failure. To determine whether 190 Building secondary process water pump capacities are adequate for current minimum reactor water pressure requirements, process water pump trip-cut tests are being conducted at all rea… more

Application of the Ewing Equation for Calculating Thermal Conductivity From Electrical Conductivity

Description: The usefulness of the Ewing equation for calculating the thermal conductivity of reactor metals and alloys from electrical resistance, specific heat, density, and atomic weight was investigated. The alloys investigated were Zircaloy-2, HSZA, Nb- 5.5 wt% V, Inconel, 18-8 stainless steel, and eutectic NaK. The Ewing equation was found to give calculated values with a degree of confidence similar to that of actual measured values. (auth)

Application of the mercury-catalyzed aluminum jacket dissolving technique to the Redox process

Description: The possible means of removing aluminum jackets from uranium slugs were considered before Hanford start-up in 1944, and have been considered at other sites for processing other types of slugs. The sodium hydroxide-sodium nitrate dissolution, which served well for Bismuth Phosphate plant operation was accepted for use in the Redox plant. The other means of jacket removal, namely, dissolving the jacket in nitric acid with the aid of mercury as a catalyst, has been adapted for use at Arco and offe… more

Battelle Memorial Institute trip report, November 1953

Description: The hot pressing die successfully bonded a composite of Ni plate U and Al. A die for step processing is being fabricated. Cu and Mg additions to the AlSi bath lower the dipping temperature but increase intermetallic formation with ductility loss. Optimum dipping rate for continuous AlSi coatings has been established. Extrusion of Al over a cylindrical core was successful. 7.5% Zr-U is not sensitive to oxygen content under crevice corrosion in boiling demineralized water. A method was developed … more

Berkeley Proton Linear Accelerator

Description: A linear accelerator, which increases the energy of protons from a 4 Mev Van de Graaff injector, to a final energy of 31.5 Mev, has been constructed. The accelerator consists of a cavity 40 feet long and 39 inches in diameter, excited at resonance in a longitudinal electric mode with a radio-frequency power of about 2.2 x 10{sup6} watts peak at 202.5 mo. Acceleration is made possible by the introduction of 46 axial "drift tubes" into the cavity, which is designed such that the particles travers… more

Bevatron Research Meeting I - Bevatron as a Research Instrument

Description: The Bevatron status is: (1) Physical structure of magnet now assembled and being tested. Initial pulsing to rated field currents indicate that magnet is performing as designed. Currents of the order of 8500 amps peak have already been rendered. (About 15,000 gauss). (2) Pumpdown time to approximately 10{sup -5} mm Hg is of the order of 24 hours at present but is expected to improve to 12-15 hours as the high vapor pressure solvents are removed. Lofgren and Brobeck expect that it will be possibl… more

BEVATRON RESEARCH MEETING III - BEVATRON THEORY

Description: Despite the essentially independent development of the Cosmotron and Bevatron, these two accelerators have general specifications which are the same within a factor of 2-3 in their pertinent characteristics. An electron analogue of the Bevatron would be an electron synchrotron operating in the 5 kev to 3 Mev range.
