The manual discusses the operation and design specification of the BD and has a description of the instructions used. The complete set of non-CAMAC instructions for the BD is given. Programming examples for several types of modules and standard function codes for CAMAC are presented. A complete set of schematics is available, but is not included. (auth)

The scaling laws for a linear theta-pinch reactor are developed. Conventional magnetic heating and laser heating of the plasma are compared. It is shown that, if a confining magnetic field of 400 kG is used, a power producing reactor need be only 1.2 km long. (32 references) (auth)

A compatibility test procedure was developed to study the reactions between lithium, refractory metals, and insulating ceramics. In the first series of tests, boron nitride was found to be completely dissolved by lithium in 600 h at 1270K. The refractory metals were borided, and the nitrogen went into solution in the lithium. The results are interpreted from a thermochemical standpoint. (auth)

Simultaneous temperature and velocity measurements were made in the near- field region of the surface thermal discharge at the Point Beach Unit 1 and Palisades Nuclear Power Plants on Lake Michigan. Data collected include measurements of temperature and velocity at the 0.5-, 1.0-, 1.5-, 2.0-, 2.5-, and 3.0-m depths, along with measurements of ambient lake and metenrological conditions. Bottom depth was also measured at variouss locations. four such surveys were made at the Point Beach plant, three at the Palisades plant. To examine the jet features from the abpve surveys and facilitate a comparison with analytical model predictions, a computer program was written to smooth the data, extracting such jet characteristics as trajectory, centerline temperature decay and temperature half-widths, centerline velocitv decay and velocity half-widths, temperature and velocity half-depths, and isotherm areas. Four near-field analytical models often used in environmental impact evaluations of power-plant surface discharges are compared to the jet characteristics determined from the smoothed jet data. The Pritchard model compares rather well with these limited data and is often conservative when model-data discrepancies exist. The Stolzenbach -Harleman and Prych models predict too rapid a temperature and velocity decay accompanying too great a lateral spread. The Motz --Benedict model …

Physical, chemical, and mechanical properties of thorium nitrides, alone and in combination with other nitrides and other thorium compounds. are collected from the literature through January 1973 (51 references). The thorium-nitrogen phase equilibrium is reviewed. Although mechanical property data are still sparse, recent physical and chemical characterization of ThN has confirined its high metallic conductivity, furnished detaii on hydrolysis and oxidation, and expanded the knowledge of the (Th,U)N and Th(C,N) systems.

EZQUERY is a generalized information retrieval and reporting system developed by the Data Processing Services Department to provide a method of accessing and displaying information from common types of data-base files. By eliminating the costs and delays associated with coding and debugging special purpose programs, it produces simple reports. It was designed with the user in mind, and may be used by programmers and nonprogrammers to access data base files and obtain reports in a reasonably brief period of time. (auth)

The erosion of ferrous- and nickel-alloy walls in fusion reactors from impinging, energetic D, T, He, and Ar ions and neutrals is discussed. The two major machanisms of erosion are sputtering and blistering. Pertinent data are reviewed to obtain estimated or experimental sputtering yields in the energy range 100 eV to 10 keV. The spuntering coefficients for Ar, He, and T are roughly 10/sup 2/, 10, and 1.5 times the value for D (at the same energy). Erosion from blistering is unimportant for Ar, unexamined for D or T, and probably comparable to sputtering for ~10-keV He. (auth)

The effect of component performance perturbations on the efficiency of injection of neutral beams into thermonuclear reactors is discussed for a apecific type of a neutral-beam injector. Based on the model chosen, which includes using direct conversion of the unneutralized portions of the ion beam and recovery of the losses from each element of the injector system, quantitative effects of component performance perturbations are presented as a function of the injected-deuterium-atom energy, using positive and negative deuterium ions. The component performances having the largest leverage on the system efficiency are, in decreasing order, the accelerator efficiency, the trapping fraction, the neutralizer loss direct conversion, and the neutralizer power efficiency.

The capability of using eddy current techniques to measure the thickness of nickel plating on carbon steel is investigated. Factors examined are the influence of: different plating baths (Watts and Sulfamate), different substrates (A285 and A516 carbon steels), and the effects of using different types of eddy current instrumentation (phase sensitivity versus amplitude sensitivity). The results show that the thickness of nickel plating (for the conditions described) can be measured accurately using eddy current techniques, if proper procedures are followed. These procedures are described along with many other variables that are associated with tests of this type. (auth)

A 33-treatment injection-molding study was performed as an extension of earlier pressure transducer work reported in BDX613-601. The recent study dealt with four variables (Cavity thickness, injection pressure, mold temperature, and melt temperature) and their effects on internal Cavity pressure distribution of a thermoplastic molding. A significant change in Cavity pressure response occurred when the mold Cavity thickness was reduced to approximately 0.080 inch (2.03 mm). The internal Cavity pressure distribution was nearly identical for the same combinations of injection pressure, mold temperature, and melt temperature when the Cavity thickness was 0.0960 and 0.2605 inch (2.435 and 6.617 mm). Injection pressure was highly significant in the prediction of internal Cavity pressure for all Cavities tested. Melt temperature was highly significant for the thinnest Cavity (0.0650 inch) (1.651 mm). Mold temperature, over the range tested, was not significant in altering measured internal Cavity pressure for any of the mold inserts. (10 tables, 22 figures) (auth)

The LLL Evaluated Nuclear Data Library (ENDL) was translated into the ENDF/B Format. This translation is for the convenience of those people who wish to use the ENDL data, but whose main familiarity is with the ENDF/B formats and procedures. Only the portion of ENDL which deals with neutioninduced interactions (including photon production from neutroninduced reactions) was translated. Those parts of the ENDL library which deal with charged-particle- induced reactions were not translated, since they cannot be accommodated within the ENDF/B system. In order to provide a basis ior judging the validity of the ENDL data calculations were made of the output neutron time spectra from the LLL pulsed-sphere experiments, by using for the calculations both the ENDL cross sections and the ENDF/B-III cross sections. Comparisons between these two sets of calculations and the experimental output neutron time spectra provide a basis for judging the relative merits of the ENDL and ENDF-/B-III data sets in the 5 to 20 MeV neutronenergy regime.

The Aerial Radiological Measuring System (ARMS), operated for the U. S. Atomic Energy Commission, was used to perform aerial surveys of several operational and non-operational reactor sites during the summer months of 1968. The data collected on these surveys included aerial photographs of the installations, aerial radiation survey data consisting of exposure rates normalized to 3 feet above the ground plus gamma-ray spectral charts, effluent characterization for operational sites (intensity rates and isotope constituents), and pertinent descriptive information of the installation. This report presents the data collected on the Big Rock Point reactor survey. (auth)

The Analytical Methods Manual Part I describes the methods used in the Remote and Service Analysis Laboratory at the Idaho Chemical Processing Plant.

The dependence of the neutrino total cross section sigma /sub nu / on neutrino energy was measured up to 160 GeV. The data are consistent with a linear dependence with slope (0.58 plus or minus 0.25) x 10/sup -38/ cm/suup 2/ GeV. The ratio of the antineutrino to the neutrino total cross section sigma / sub nu / sigma /su b nu / was found to be approximately constant up to 70 GeV at a value which is consistent with the numerical value of 1/3 expected for the scattering of neutrinos and antineutrinos by relativistic pointlike spin 1/2 fermions.

A flexible low resolution spectrometer is being built for a program of experiments to be done at the LAMPF Nucleon Physics Lab. The bend angle of charged particles through an 18D36 magnet will be determined by multiwire proportional chambers (MWPC) with 2-mm wire spacing. The general design of the chambers and of the associated electronics for readout and encoding are discussed. Some results obtained with a prototype system are given. (auth)

Although grinding inherently produces a better involute form and finer surface finish than other basic gear-fabrication methods, equipment, and experience in grinding 120-pitch gears with 0.100inch pitch diameter were not available when Bendix Kansas City placed a process development contract with the Fellows Company. Bendix had been producing a functional miniature gear by hobbing, but the required surface finish was borderline and burrs on the part were difficult to remove. As a result of this project, a repeatable process was developed for grinding the tooth form and maintaining a l6AA surface finish with minimum burrs. An experimental machine was used in this process development; production equipment is not yet available in U. S. industry for this process but could be developed. (auth)
