Incentives for using poison splines at C Pile

Description: The benefits of the poison spline system as developed and partially tested by the Facilities Engineering Operation are considered over a two year period. The full pile operational charge-discharge installation at the end of that time could make the poison spline system a marginal operation. This document list the production gains that are possible, how these gains compare with the cost of the poison spline system, and how this system compares with other available supplementary reactivity contro… more

The Primary Quantum Conversion Process in Photosynthesis: ElectronSpin Resonance

Description: Photoinduced electron spin resonance signals have been observed in isolated chloroplasts and other green materials with a growth time not affected by reducing the temperature to -140 deg. This is interpreted in terms of conduction-band and trapped-electron theory.

Carbide Coatings on Graphite

Description: A method has been developed for the uniform coating of graphite tubes with carbides of niobium, tantalum, and zirconinm by thermal decomposition of their respective halide vapors. Conditions of coating temperature and pressure are so chosen as to prevent the deposition of metal, but to permit the formation of the carbide as rapidly as carbon can diffuse to the surface. If the carbon diffusion can be made the rate-limiting step, the coating process becomes self- regulating and uniform thickness … more

Altitude performance of a full-scale turbojet engine using pentaborane fuels

Description: From Introduction: "The data presented herein include the standard engine performance parameters of net thrust, specific fuel consumption, and engine total-pressure ratio that reflect the performance available from the use of pentaborane as a fuel. The influence of the boric oxide deposits from the high-concentration pentaborane fuels on engine component performance is presented."

Recovery of cesium from Purex plant wastes by metal ferrocyanides and ferricyanides II: Full level laboratory investigations

Description: Laboratory scale experiments with synthetic Purex 1WW and HAW have demonstrated the feasibility of recovering cesium by precipitation with metal ferrocyanides and ferricyanides. One method for recovery of cesium involves neutralization of the precipitate ferric hydroxide and sodium diuranate, and recovery of cesium from the supernate by precipitation with zinc ferrocyanide. Another method involves precipitation with nickel or ferric ferrocyanide from partially neutralized 1WW, or from HAW. The … more

Cyclotron Resonance Heating of a Deuterium Plasma

Description: Abstract: "The energy gained by a deuterium plasma, from a three megacycle per second radiofrequency field, was studied experimentally. A static magnetic field, in the form of a "mirror", was used. The coil of an rf resonant circuit, placed at the center of the machine produced a time-varying magnetic field parallel to the static field. This, in turn, induced an electrical field, in an azmuthal direction, which acted on the ions. When this was in synchronism with the cyclotron frequency, the io… more

Waste tank temperature studies

Description: This report concerns the continuing problem of providing waste tank designs which will insure safe storage of radioactive waste over long periods of time. These tanks must withstand severe stresses imposed by earth loading, by hydrostatic pressure and by temperature gradients. The temperature gradients are caused by contained in the waste. The waste entering the tank is relatively cold, but the temperature rises rather rapidly to the boiling point as filling proceeds and then the temperature co… more

TRANSFORMATIONS IN URANIUM-BASE ALLOYS. Summary Report for December 14, 1955-March 31, 1957

Description: Transformation kinetics of binary U -Nb and ternary U-Nb-base alloys were investigated. Additions included zirconium, chromium, titanium, silicon, nickel, nnthenium, and vanadium. Encapsulated samples were given a homogenizstion anneal at 1000 or 1100/sup o/C, water-quenched from 906/sup o/C to retain the phase, and reheated to temperatures between 360 and 600/sup o/C. The metastability of the phase was examined by metallographic, hardness, resistometric, dilatometric and x-ray-diffraction tech… more

THOREX PILOT PLANT: SYSTEM FOR CONCENTRATING SECOND URANIUM

Description: A system for concentrating uranyl nitrate solutions was designed and installed in the Thorex Pilot Plant. A total of 16,060 g of uranium was concentrated in the system in 68 batch runs. A total of 14,400 g total uranium (14.180 g U/sup 233/) was recovered as product suitable for shipment. Uranium loss to the evaporator condensate was 0.03% of ihe total uranium processed. The material balance across the system was 98.4%. The average concentration of uranium in the evaporator feed solution was 29… more

Theoretical rocket performance of JP-4 fuel with mixtures of liquid ozone and fluorine

Description: Data were estimated by means of a heat correction equation using data for JP-4 fuel with mixtures of oxygen and flourine. The estimated data were checked for several cases by direct calculations. The difference in specific impulse between the estimated and directly calculated values was from 0.2 to 0.8 pound-second per pound. The maximum value of specific impulse was 334.9 pound-seconds per pound for a combustion-chamber pressure of 600 pounds per square inch absolute and an exit pressure of 1 … more
