C reactor overbore fuel failures

Description: The concept of overboring the graphite channels in an older Hanford reactor and installing oversized tubes charged with oversize fuel elements is being investigated at C reactor. Recently a column of these oversized test fuel elements exhibited three uranium cleavage (split) type failures after experiencing severe reactor flux cycling. This report presents a preliminary description of both the fuel failures and the flux cycling encountered by the reactor.

Linearized Three Component Magneto-Hydrodynamics

Description: "A linearized three component MHD theory is given. The three components are two oppositely charged species and a neutral species. Linearized macroscopic equations are presented which in the limit of vanishing magnet field reduce to fluid dynamical equations, and in the limit of vanishing neutral components is frictional. In addition the sound speed that enters is a function of three equilibrium densities. These equations yield a dispersion relation which is tenth order in the wave speed. The d… more

An Evaluation of Four Processes for Recovering Uranium From Zirconium Fuels at the Idaho Chemical Processing Plant

Description: Four zirconium fuel processes -the present STR process, the modified Zirflex process, the barium fluorzirconate process, and the sodium formate process-were evaluated in detail for technical and economic feasibility. The evaluation was based on installation as the second generation ldaho Chemical Processing Plant zirconium process. Two nonaqueous processes, the ARCO and the fused salt fluoride volatility processes, were included in a preliminary evaluation, but were eliminated on the basis that… more

An Integral Design Technique for Wideband Multistage Transistor Amplifiers

Description: Presented herein is a philosophy for designing wideband multistage transistor amplifiers. The amplifier is visualized as an integral unit, the interstage networks constituting the elements of the amplifier unit. By designing the amplifier as a unit and adjusting the overall response (gain and bandwidth) with the interstage time constants, an increase in gain-bandwidth product is realized over the iteratively designed amplifiers. The resulting increase in gain-bandwidth product results from abse… more

An Integral Design Technique for Wideband Multistage Transistor Amplifiers

Description: A philosophy for designing wideband multistage transistor amplifiers is discussed. The amplifier is visualized as an integral unit, the interstage networks constituting the elements of the amplifier unit. By designing the amplifier as a unit and adjusting the over-all response (gain and bandwidth) with the interstage time constants, an increase in gainbandwidth product is realized over the iteratively designed amplifiers. The resulting increase in gain- bandwidth product results from absence of… more

MACE--A Monte Carlo Evaluation of Fast Neutron Collimators

Description: MACE is a Monte Carlo code, written for the IBM 7090, to evaluate the efficiency of radiation collimators in terms of the ratio of collided to uncollided flux reaching a target. The analysis can be performed with as many as 30 energy groups. Up to 5 materials (8 elements) may be used in the description of the collimator system. Provisions are included for specification of source particle density and angular distribution functions and for tilt of the source plane with respect to the axis of the … more

A Study of Modifications for Ornl Liquid Waste System. I. High-Level Storage Tanks and Intermediate-Level Evaporator

Description: As a means of reducing the quantity of radioactivity released to the environment by radioactive liquid waste discharges at ORNL, it is proposed that two 50,000-gal stainless steel storage tanks and a 600 gph stainless steel, submerged-coil evaporator be installed. The tanks, approximately 10 ft in diameter by 85 ft long, will be equipped with cooling coils attached to their outside surfaces for removal of a maximum of 300,000 Btu/hr of decay heat, and will be supported inside a concrete vauit f… more

Equation of State of Classical Systems of Charged Particles

Description: Recent developments in the classical theory of fully ionized gases and strong electrolyte solutions are reviewed, and are used to discuss the equation of state at high temperature and low densities. The pressure is calculated using the ring-integral approximation, and quantitative estimates of higher correction terms are given. The effect of short-range repulsive forces is shown by comparing the results with two kinds of potential functions: hard spheres of diameter a, and "soft" spheres for wh… more

EVALUATION OF (Th,U)C$sub 2$, CARBON-COATED (Th,U)C$sub 2$ PARTICLES, AND CARBON COATINGS

Description: Thorium and uranium carbide nuclear fuel particles were evaluated by metallographic and x-ray diffraction techniques. Techniques were developed to etch the polished surface of Th--U carbide to reveal the grain structure. In addition, techniques to determine particle density and coating thickness were developed. Comparison of the data indicates that the use of spherical particles allowed for more precise determination of the coating thickness, density, and strength of coatings. Strength of indiv… more

NPR Physics Startup Testing Program

Description: The New Production Reactor, as compared to existing Hanford reactors, employs new and unique design concepts. To properly evaluate these design concepts and their effects on reactor operations, nuclear safety, and reactor life, a comprehensive testing program is planned; this program, with its objectives and restrictions, is discussed in this report. It has been developed along the same line as the C and K Reactors test, programs, and is expected to require a total time of 6--8 weeks of round-t… more
