1706 KE Water Treatment for Out-of-Reactor Test Facilities.

Description: Water treatment systems for preparing and maintaining high purity water in out-of-reactor or in-reactor test oops are becoming increasingly important. In out0of-reactor experiments the presence of ionic impurities in the water has a marked influence on film formation and corrosion rates. It is therefore , imperative that these impurities be maintained at the lower practical concentration.

Advantages of palmolive alternate

Description: It has been proposed that Pu-238 be produced by irradiating neptunium solution in one or more loops in a reactor and then recovering the Pu-238 in a close-coupled separations plant. Such a scheme could replace the more conventional scheme of solid element fabrication, irradiation, and reprocessing for plutonium and neptunium recovery. This document presents the advantages of such a scheme from the standpoint of product purity and Pu-238 production.

The Agglomeration of Solid Aerosol Particles. Technical Report No. 16

Description: The variations of size and density of aerosol particles were examined. Experiments were made with a wide variety of substances using a modification of Whytlaw-Gray and Patterson's methods in which freefall velocity was determined. The mass was estimated both by balancing the gravitational and electrostatic forces and from rising velocities under constant field strength. The results were compared with the shape and structure of the aerosols shown by electron microscopy. The variation of the Stok… more

Air Diffusion in the Air Operating Water Flask. Section I. Test Results DL-S-205 (T-641110)

Description: The purpose of the test was to determine the effect of continuous air pressurization of the Valve Operating System water flask on the the oxygen concentration of the water in the flask. Oxygen concentration in the Valve Operating System water flask increased during the testing period of seventeen days. It cannot be determined from the data obtained if equilibrium oxygen concentration was reached. The distribution of oxygen in the flask at the end of 17 days varied from approximately 12 ppm in t… more

Analysis of Tapered Circular Plates

Description: Tables of numerical values of all necessary functions and instructions on their use in the stress analysis of circular plates which have a linear thickness-radius relationship, and which are loaded axisymmetrically, are presented. The analysis is based on the classical smalldeflection theory. Emphasis is placed on plates whose thickness at the inner radius is greater than the thickness at the outer radius. However, a limited number of plates for which the opposite is true may also be analyzed b… more

APPLICATION OF ULTRAHIGH-PRESSURE HIGH-TEMPERATURE EQUIPMENT TO STUDY OF UO$sub 2$ REACTIONS

Description: Equipment and techniques for high-pressure high temperature solid-state studies were developed, and some preliminary results for the reaction of uranium oxides with other oxidcs were obtaincd. A new die design was evolved which appears suitable for any work currently contemplated. The maximum capabilities of this new die are as yet undetermined, but its theoretical pressure limit is in excess of 200,000 atm. The die differs from similar equipment in that internal heating of the sample is employ… more

Calculational Models of Pot Calcination

Description: A simplified model for solids deposition in the pot calcination of waste was analyzed, and numerical calculations were made. In long calcination pots of 10 to 12 in. diameter, calcination times should not exceed 24 hours and might be as low as three hours if the pot is kept full. If the pots are fed at a constant rate, the cake might form with a steady state V'' when viewed in vertical section which would progress from bottom to top. Cake deposition rates appear to be independent of pot radius.… more

Calibration of Omre Fuel-Element Surface Thermocouple Assembly

Description: Studies were made to determine the actual surface temperature of OMRE fuel elements if the thermocouple were not present. Chromel-alumel thermocouples are being attached to the fuel plate cladding of Type 304 stainless steel. These wires are in contact with the coolant stream. Heat transfer from the thermocouple junction, by conduction along the lead-wires and by forced convection to the coolant, produces a lowering of the surface temperature in the region of the junction which results in an er… more

Chemical Engineering Division Summary Report for October, November, December 1958

Description: Fluoride Volatilization Separations Process. Work has continued on the development of fluoride volatilization processes for recovery of U and Pu from spent power-reactor fuels. Results are reported on the fluorination rates of U and Pu oxides and fluorides. The conversion rate of UO/sub 2/F/sub 2/ to UF/sub 6/ by elemental fluorine was determined as a function of temperature. Uranium trioxide is fiuorinated at a slower rate than the other U compounds investigated. On exposure to fluorine PuO/su… more
