ABCXYZ: vector potential (A) and magnetic field (B) code (C) for Cartesian (XYZ) geometry using general current elements. [In LRL TRAN for CDC > 600 computer]

Description: ABCXYZ is a computer code for obtaining the Cartesian components of the vector potential and the magnetic field on an observed grid from an arrangement of current-carrying wires. Arbitrary combinations of straight line segments, arcs, and loops are allowed in the specification of the currents. Arbitrary positions and orientations of the current-carrying elements are also allowed. Specification of the wire diameter permits the computation of well-defined fields, even in the interiors of the cond… more

Analysis of abnormalities of snubbers in nuclear-reactor service (Report 1)

Description: An investigation was conducted of malfunctions of snubbers (seismic-shock arrestors) in service in nuclear power plants. The construction and use of snubbers is summarized, and the history of snubber problems in nuclear service is reviewed. Reports of many hundreds of snubber malfunctions were found in the abnormal-occurrence reports of the docket literature. The great majority of these abnormal occurrences consisted of hydraulic snubbers whose hydraulic fluid had leaked out because of deterior… more

Analysis of ceramic materials for impact members in isotopic heat sources

Description: Of the available high strength ceramics, silicon nitride offers the most promise followed by silicon carbide and aluminum oxide, and stress analyses show severe limitations on allowable velocities for impact with granite following reentry for these ceramics. Impact velocities in the 100 to 200 fps regime can be achieved only by the addition of an additional layer to distribute the high contact stress. Besides impact limitations, application of ceramic materials in heat sources would present pro… more

Cryoforming evaluation using high-purity nickel

Description: The cryogenic forming process was evaluated using nickel 270 to see if it had significant advantages over room-temperature (RT) forming. Typically, the procedure involved fast-strain-rate forming a set of nickel samples at cryogenic temperatures and another set at RT. Both sets were measured at RT for failure strength and their strength-preparation elongation curves compared at equal strains. Two more sets were formed, this time at slow strain rates (one at cryogenic temperatures, the other at … more

Decay of /sup 99/Mo

Description: Relative intensities for K x-rays and gamma rays emanating from /sup 99/Mo in equilibrium with its /sup 99/Tc* daughter have been measured using several Ge photon detectors. Combining these intensities with an evaluated set of electron-conversion coefficients has provided a set of absolute intensities for the observed gamma rays. The absolute intensity for the dominant 140.5-keV gamma ray in /sup 99/Tc was determined to be 90.7 +- 0.6/100 /sup 99/Mo disintegrations for /sup 99/Mo decay in equil… more

Deep exploratory test holes for waste repository investigations

Description: A significant number of deep boreholes have been drilled within the Permian Basin to investigate subsurface geologic conditions for waste storage utility. As these investigations have yet to reveal a single ''acceptable site,'' it is quite clear that many deep test holes can be expected to be drilled and several study areas ''abandoned'' before specific sites for pilot plants and/or for permanent repositories are selected. Indeed, this has been the case in the Permian Basin, and there is little… more

Equation of state and shock entropy of CaCO/sub 3/

Description: The energy released in a nuclear detonation can vaporize the surrounding medium. If one knows the gaseous equation of state of the medium, it can be used along with estimates of the shock entropy to predict such things as cavity size and seismic effects. We have calculated the equation of state and shock entropy for calcite (CaCO/sub 3/). We formulated the gaseous equation of state for pressures between 1 and 10/sup 6/ bar and temperatures from ambient to 1000 eV using a combination of the TIGE… more

Fluidized bed incineration of radioactive waste. [Transuranics]

Description: A fluidized-bed incineration facility is being designed for installation at the Rocky Flats Plant to demonstrate a process for the combustion of transuranic waste. The unit capacity will be about 82 kg/hr of combustible waste. The combustion process will utilize in situ neutralization of acid gases generated in the process. The equipment design is based on data generated on a pilot unit and represents a scale-up of nine. Title I engineering is at least 70 percent complete. (auth)

GRAY: a program to calculate gray-body radiation heat-transfer view factors from black-body view factors

Description: Program GRAY is written to perform the matrix manipulations necessary to convert black-body radiation heat-transfer view factors to gray-body view factors as required by thermal analyzer codes. The black-body view factors contain only geometric relationships. Program GRAY allows the effects of multiple gray-body reflections to be included. The resulting effective gray-body factors can then be used with the corresponding fourth-power temperature differences to obtain the net radiative heat flux.… more

Holographic determination of the yield strength of a welded stainless steel pressure vessel

Description: The strength and toughness of a high energy rate formed (HERF'ed) stainless steel, as influenced by the heat input from a variety of welds, are being measured. Using holographic interferometry, a welded spherical pressure vessel constructed from HERF'ed stainless steel with a composition of 21 percent Cr, 6 percent Ni, 9 percent Mn, 0.23 percent N, balance Fe was examined. Holographic examination of the weld vicinity shows that plastic deformations in the heat affected zones reach a maximum at … more

Stacking in the Fermilab doubler

Description: The feasibility of stacking beam in a storage ring by the phase displacement technique, i.e. by the accumulation of momentum strips, is determined by a complicated interplay of many factors. Some of these factors are discussed, especially as they relate to stacking beam in the Fermilab doubler ring, but no attempt is made to present a consistent solution. An arbitrary division is made into five subject categories connected with the stacking process: (1) momentum dilution, that is, the dilution … more
