2D PERT. A TWO-DIMENSIONAL PERTURBATION CODE (open access)

2D PERT. A TWO-DIMENSIONAL PERTURBATION CODE

Given multigroup fluxes and adjoint fluxes of any cylindrical R-Z configuration, 2D PERT may compute: the prompt-neutron lifetime; the relative worth of various delayed neutrons; the integrals of capture, fission, etc., of given materials over any given region; local perturbations, i.e., danger coefflcients; and integrated perturbations, i.e., reactivity effect of uniform variation in the cross sections affecting a whole region. 2D PERT is programmed for a 32K IBM-704 using 3 tape units. The code is written in FORTRAN with the exception of two SAP subroutines. Input fluxes and adjoint fluxes are on tapes which may be obtained either directly from CUREM output or manufactured by a special tape-writing routine. Homogeneous cross sections and variations of these cross sections are either read in as input information or are computed by the code from a microscopic-cross-section library and atomic densities given as input. A combination of these methods may be used. (auth)

Application of Boron Carbide Nickel Dispersion to a Prototype Control Rod

Previously reported results on the testing of small samples of boron carbide dispersed in nickel by electrolytic codeposition were adequately encouraging to lead to the development of a prototype control rod for operation in the Vallecitos Boiling Water Reactor. The operation of the control rod has been entirely satisfactory.

Chlorination of Uranium and Fission Product Oxides in Molten Halide Media (open access)

Chlorination of Uranium and Fission Product Oxides in Molten Halide Media

The chlorination of mixtures of uranium and fission product oxides in various molten halide systems by sparging with a chlorine-carbon monoxide mixture was investigated. The chlorination reaction causes the suspended oxide to form species that are soluble in the molten salt and removes some of the fission product elements by volatilization of the chlorides. The rate ot oxide dissolution and the fission product behavior both proved to be dependent upon the composition of the molten halide medium used. (auth)

COATING OF UO$sub 2$ PARTICLES WITH BeO BY SOLUTION METHODS

Spherical particles of beryllium oxide containing and enclosing UO/sub 2/ particles (-1O micron) were prepared by dispersing a suspension of UO/sub 2/ in a concentrated viscous solution of a basic beryllium saIt in a liquid organic medium, drying, and firing. The spheres produced were porous and would require densification to make the beryllium oxide protective to the UO/sub 2/. Precipitation of beryllium hydroxide or carbonate on UO/sub 2/ particles suspended in solutions of beryllium salts under various conditions produced no actual coating of the UO/sub 2/ particles.

THE DISTILLATION OF URANIUM HEXAFLUORIDE AND BROMINE PENTAFLUORIDE IN A 0.5- INCH-DIAMETER PACKED COLUMN

The efficiency of a 0.5 in. dia packed column with 1/16 in. nickel helices for the separation of the binary system UF/sub 6/-- BrF/sub 5/ was investigated. Several distlllations were performed wlth the system methylcyclohexane and nheptane for purposes of callbration. For both systems, pressure-drop measurements at various flow rates were determined and the flooding rates were determined from these. Experiments to determlne the equilibrium time were also conducted with both the organic and inorganic systems used for calibration. The separation efficiency was calculated as Htu/sub g/. The flooding rates determined were 570 for methylcyclohexane, 2680 for uranlum hexafluoride, and 2200 lb/(hr) (ft//sup 2/) for bromine pentafluoride. Equilibrium times of 34 and 24 hr were found for the organic and inorganic systems, respectively. The Htu/sub g/ was found to be 1.2 in. for flows of 50 to 450 lb/(hr)(ft//sup 2/) for the organic system. The Htu/sub g/ for the inorganic system was 1.3 in. at flow rates above 285 lb/(hr)(ft/sup 2/) and was found to increase to almost 3 in. at flow rates below this. (P.C.H.)

Economic Evaluation of Control Rod Materials and Fabrication Processes

Control rod materials, designs, and fabrication processes were compared for their relative economics. Control rod lifetime data were calculated with a simple approximation of nuclear worth depreciation. These data were used in conjunction with the estimated fabrication costs to determine the cost of using several absorber materials in a typical power reactor on a cost-per-year basis. The effect the control system has on core power density and fuel lifetime was included. (auth)

Effect of Oxygen on Mechanical Properties of Niobium (open access)

Effect of Oxygen on Mechanical Properties of Niobium

From abstract: "The effects of oxygen on some mechanical properties of niobium were studied over the composition range of 20 ppm to 2400 ppm oxygen. The tensile properties of samples of these compositions were studied over the temperature range from room temperature to 500°C. Hardness values were obtained at room temperature only. The following observations and conclusions were made during these studies: 1. Oxygen additions to high purity niobium increase both the yield and tensile strengths of niobium at all temperatures investigated. As the temperature is increased above 250°C the effect of the first 200 ppm of oxygen has more influence than further additions on these strengths of niobium. 2. Strain aging behavior is observed. The peaks in the tensile strength versus temperature curves can be predicted with reliability by the relationship proposed by Cottrell, 3. A mechanism is proposed which, along with Cottrell's segregated atmosphere mechanism, can account for the serrated stress-strain curves obtained. This mechanism offers an explanation of the occurrence of serrations at room temperature, and the mechanism is composition dependent."
