The phenomenon of the electromagnetic pinch effect is used to accelerate ionized gases for space propulsion. Electrical energy, initially stored in capacitors, is discharged across two nozzle shaped electrodes wherein the radial pinch is converted to axial motion of the effected gases instead of confinement at the axis. The gas dynamics of a pinch using the hydrodynamical model of a msgnetic piston driving a shock wave is combined with the electrodynamics of the circuit to calculate the discharge behavior. Experiments on three different electrode designs are discussed and results compared with calculated values. Results are applied to one particular space propulsion system consisting of a nuclear energy source, a space radiator, a turbine-generator, capacitor, and a pinch tube. The specific mission analyzed is a one-way unmanned flight to a Mars orbit, starting from an Earth orbit. (auth)

Script from the WBAP-TV/NBC station in Fort Worth, Texas, covering a news story about two Fort Worth burglar suspects sending city, county, and state officers to the Trinity River Bridge. Allegedly, a shoe box full of gold was dropped off of the bridge by the burglars. Sonny Able and Merle Hariston admitted to twenty two burglaries throughout the state. The gold and teeth were stolen from the Cary Dental Supply company in Fort Worth. E. N. Buie and Texas Ranger E.J. Wimberly arrested the two for routine investigation. The pair are both wanted in Amarillo and Big Springs.

Abstract: "Most of the Nuclear Merchant Ship Reactor (NMSR) shield design work performed by The Babcock & Wilcox Company (B&W) is summarized. Primary and secondary shield results are presented, consistent with contractual requirements and designated design criteria. Methods of calculation and basic parameters are shown" (p. 1).

Efficiency of the pilot plant pumper-decanters was greatly improved by the maintenance of interfaccs. The low efficiency of the D-3 pumper-decanter in the plant could be substantially raised by an interface to prevent backmixing. A review of refinery performance, based on a correlation of wash raffinate density with extract uranium saturation showed that high-thorium product resulted from low extract saturation. Tributyl phosphate recovery by hexane stripping of raffinate can be greatly improved through the use of a pamper-decanter in place of the present open column. The pilot plant fluid-bed denitrator has been operated at production rates as high as 500 lb UO/sub 3/hr-sq ft using hlgh feed concentrations. Correlations of previous particle size and heat transfer data are presented. A pilot plant fluid-bed reduction reactor with a tapered internal mandrel has been placed in service. The equipment has performed well in preliminary runs. Equipment to convent low concentration to 38% HF by distillation has been installed. Runs have been made in the green salt reactors in order to simulate the conditions whereby the 38% HF will be utilized. These runs demonstrate the ability to produce high-quality UF/sub 4/ utilizing 38% HF to the Air reactor tube. Laboratory analysis of green …

The effects of simulated space vehicle vibration, acceleration and shock on the operation and efficiency of a SNAP-III thermoelectric generator are described. The test specifications were developed by Jet Propulsion Laboratories for the third stage and payload of the Vega Vehicle. (auth)

The SPAN-2 code calculates the uncollided gamma flux at a point outside a right circular cylinder which is surrounded by cyllndrical shell shields and above which are plane slab shields. The cylinder is assured to contain a source of gamma radiation which varies in the radial and axial directions only. Field points may be located in a plane through the axis of the cylinder. The method of integration used is three-dimensional Gaussian quadrature. Typical computing and editing time for a 20 field point problem, in which there are 10 side and 10 top shields, is four minutes per energy level. A 32,768 word IBM-704 is required for the code.

A one-step, continuous, fluid-bed process for the conversion of uranium hexafluoride to uranium dioxide was successfully carried out in preliminary experiments in a 1 1/2-inch-diameter Monel reactor. Hydrogen and steam were used for simultaneous reduction and pyrohydrolysis reactions carried out at 600 deg C, resulting in the formation of a dense coating of dioxide on the starting bed of uranium dioxide. The effects of uranium hexafluoride feed rate and reactant excesses on conversion were investigated. Results of fluid-bed steam pyrohydrolysis runs on uranium tetrafluoride are also presented.

Development of a nuclear density gage is reported. A diation transmitted through a sample and through a calibrated wedge. In simple cases the two radiation beams are mechanically chopped at 60 cycles, and the difference in intensity activates a servosystem which repositions the wedge until balance is achieved. Development or a lead chopper for use with Tm/sup 170/ is reported. The commutating system described previously was completed and is being tested. Research has begun on the use of mechanical energy discrimation in gaging. (J.R.D.)

Data are tabulated on the radioactive content of samples of surface water, lake and stream bottom silt, soil, plants, and air filters from the environs of the Argonne National Laboratory. Results are compared with those for similar samples collected from the area from 1952 through 1958. Fission prcduct activity from nuclear detocations was found in most samples from all locations. Fall-out activity was greatest during the spring and fall, and was particularly noticeable in air, precipitation, and plant samples. (For preceding period see ANL-5934.) (C.H.)

The development and design of a large bakeable valve based on a unique seat arrangement and a novel motion seal are described. The seat sealing is accomplished through the use of high pressure fluid actuation of an annular pinch gasket. Experimental data on seat closure performance, and the specific design features to achieve successful closures, are presented. The bakeable motion seal utilizes a stainless steel bellows sleeving over an inner concentric actuating shaft. This shaft is bent at 90 deg to the axis of rotation and is free to rotate relative to the bellows. There is no apparent size limitation to this type of actuation. The design of a 10-inch gate valve utilizing these principles is described. (auth)

The Homogeneous Reactor Test requires an emergency or dump valve for rapidly releasing the contents of the high-pressure systems to the low-pressure systems. In order to determine the most suitable trim material for this service, a loop was constructed and used to test a variety of materials under simulated reactor dump conditions. As a result of the tests both 347 and 17-4 PH stainless steels were recommended and used in the HRT dump valves. The HRT core dump valve has not been replaced since the beginning of critical operrtions. The blanket dump valve has been replaced twice since criticallty; once apparently as a result of mechanical binding and once following a dump. (auth)
