Problems of Air-Borne Contamination in Handling of Pu F₄ Powders

Description: Abstract: Studies were made of the air-borne contamination present during the operation of reducing plutonium tetrafluoride powder to the metal. Equipment design changes were made and operation technique changes were made until the amount of contamination present during operations was well below tolerance levels.

H.E.W. - 300 Area - Metal turnings - Fire hazard

Description: This memorandum discusses means to extinguish magnesium fires in metal turnings at the Hanford Engineer Works 300 Area. The storage of metal turnings in 55 gallon drums presented a fire hazard, for which an effective means for extinguishing the fire had not been presented. This memorandum is dated July 1943. (JL)

Classified information required by operators and others exposed to radiation hazards

Description: Information required by operators exposed to radiation hazards is discussed. All areas of the plant are subjected to radiation hazards similar to those in the radium industry. Personnel in these areas are required to wear pencil meters and special badges that are evidently not solely for identification. They are required to submit to medical examinations more stringent and frequent than usual. They are required to wear heavy gloves in one location, thin gloves in another, disposable hats or rub… more

Supplemental Technical Report on an Improved Process for the Manufacture of High Purity Calcium, Period Covered November 10, 1948 to January 31, 1949

Description: Abstract. Experimental work was carried out to improve material conversion efficiency and to reduce handling costs inherent in the present process for production of high purity calcium. Charges up to 54 pounds were handled successfully in the equipment available. Material losses were reduced and more complete removal of alkali and alkaline earth metals was effected by controlled pressures of inert gas and by melting under positive pressure of Argon.

Resonance Absorption of Uranium in Mixtures

Description: A good determination of the resonance absorption of uranium when admixed with various substances is necessary so that calculations can be made on the efficiency of homogeneous piles. The original experiments along these lines were undertaken by Creutz, Jupnik, and Snyder (C-116) and consisted of experiments on the resonance capture in pure U, UO2, U3O8, and one experiment on capture in a mixture of U3O8 and graphite. These experiments were done at the cyclotron in Princeton and consisted of det… more

Experiments on the Evaporation of Boron in Vacuo : Progress Report No. 1 on a Phase of Problem No. 132 - ML - 56-3; File Serial 13

Description: It was desired to determine a method of evaporating boron to form a rather pure uniform tenacious coat of specified thickness. These coats are needed as monitoring films for neutron intensities, particularly in steel ionization cylinders. The most satisfactory method of evaporating boron employed a graphite filament. A mixture of amorphous boron and Carbenoid A was painted onto the filament which was then heated by electrical resistance method to 2300 degree C at which temperature the boron eva… more

Corrosion of Tuballoy-Molybdenum Alloys by Water

Description: The primary purpose of the corrosion work was to find a tuballoy alloy which would be sufficiently corrosion resistant to be useful for canned slugs even if some of the can were to leak. The secondary purpose was to obtain general corrosion data on tuballoy alloys.

A radar method of calibrating airspeed installations on airplanes in maneuvers at high altitudes and at transonic and supersonic speeds

Description: A method of calibrating the static-pressure source of a pitot static airspeed installation on an airplane in level flight, dives, and other maneuvers at high altitude and at transonic and supersonic speeds is described. The method principally involves the use of radar-phototheodolite tracking equipment. The various sources of error in the method are discussed and sample calibrations are included.

Production research progress report, March 1--31, 1949

Description: A study has been made of the time and temperature required to anneal Teflon and Fluorothene. It has been found that, by proper annealing, the strains my be removed and cold-flow prevented. The disk stopcocks prepared with annealed plastics have not developed leaks on standing. A description is given of the modified slug-dissolver heating unit which has been installed in the Bismuth-II Process Line. Work has been continued on the absorption spectra of bismuth in hydrochloric acid solutions. Two … more

Physics group process report, April 1--30, 1948

Description: The high rate neutron scaler has been removed from service for repair. Consequent study has led to the discovery of a double counting effect. The vacuum system of the vacuum balance is being redesigned and rebuilt so as to obtain a higher vacuum. The vapor pressure of postum was measured with a quartz sickle gauge between 0.3 and 90 mm. of mercury pressure at temperatures between 430{degrees} and 745{degrees}C. The least square representation of the data is the following: Log p = {sub T}{und 53… more
