Production of Pebble-Type Fuel Elements

Description: A capillary-drop method of producing spherical shapes of brittle materials less than 0.l00 inch in diameter was developed. It appears to be a feasible means for producing large numbers of pebble-tyne fuel element cores. Coating of pebble-type fuel element cores by the coating-pan technique, though not adequately developed, showed promise. (auth)

GRAIN REFINEMENT PRODUCED BY AN ALPHA PHASE ANNEAL OF BETA PHASE HEAT TREATED AND WATER QUENCHED URANIUM

Description: During an experiment involving alpha phase annealing (at 610 to 655 deg C for 5 and 10 min) of beta-quenched uranium, it was determined that the relatively coarse, irregular shaped grains (0.08 to 0.150 mm in diameter) in the beta-quenched structure, were replaced by fine equiaxed grains (0.04 to 0.09 mm in diameter).

Particle Accelerators

Description: In the most general sense, an accelerator is any device designed to give kinetic energy to ions or electrons. According to this definition the earliest cathode ray and canal ray tubes, made before the turn of the century were accelerators, the same principle is used in the x-ray tube, the cathode ray oscilloscope, the mass spectrograph, the electron microscope, and many other modern devices. However, we shall limit this discussion to those accelerators made for the particular purpose of inducin… more

Measurement of lithium in target slugs by neutron transmission

Description: An instrument was developed to measure nondestructively the lithium content of target slugs for the SRP reactors. The slugs consist of cylindrical pieces of Li-Al alloy, approximately 0.8 inches in diameter and 12 inches in length, clad with aluminum. The instrument utilizes neutron transmission to determine the Li content in the range 3% to 7% Li.

The Elimination of Microwave Reflections

Description: Abstract: "The reflections of microwaves from the walls of a plasma-containing vessel are studied. The probable cause of the reflections is discussed, and several suggestions are made for eliminating the reflections from the waveguide in the vessel and particularly from the pyrex vessel wall and copper tubing surrounding the pyrex. Quarter-wave-thick carbon-filled plastics or glasses having a very low vapor pressure room most promising when placed inside the pyrex cylinder. BaTiO3 appears to be… more

Note on Possible Stabilization Due to Coupling

Description: Abstract: "By a simple illustration it is pointed out that, conceivably, the real coupled character of the general magnetohydrodynamic equations may lead to much slower instability growth rates, if not stabilization, than predicted from the linearized set of equations."

Attenuation properties of Hanford pile shield materials

Description: This report discusses an extended program of measurements has been carried out at Hanford to determine the attenuation characteristics of various concretes which might be used as inexpensive yet efficient shields for large, stationary, production piles. The original Hanford piles have biological

Travel to Battelle Memorial Institute to discuss the progress of subcontract research on the natural uranium and enriched uranium fuel element programs. Trip report, June 21--22 and 27, 1955

Description: The poor corrosion resistance of recent samples press-clad with 6,000 psi at 950 F is believed to have been due to the presence of a large number of stringers intersecting the surfaces of the uranium cores. A better quality metal and an improved pinch-weld will be used in the future. Machining of extrusion dies and mandrel tips by Moczik for the BMI extrusion cladding work is expected to be completed about mid-July. The first attempt to clad the internal surface of a tube by ``hot drawing`` has… more

OPERATION UPSHOT-KNOTHOLE Project 6.12 DETERMINATION OF HEIGHT OF BURST AND GROUND ZERO

Description: The purpose of this series of experiments was to test methods available to the field army for tactical determination of atomic burst location and yield over enemy-held terrain. Preliminary analysis indicated that the systems that should be tested were sound ranging, seismic height of burst determination, photographic flash ranging, and Bhangmeter type systems for yield determination. Sound ranging was accomplished using standard equipment with modified techniques. Microphone arrays of dimension… more

Photosynthesis

Description: The overall process of photosynthesis involves a number of interconnected processes. These processes, which are cyclic with respect to both energy and material, are related at some points to well-known respiratory processes. The carbon-reduction cycle in photosynthesis is now known in detail. All enzymes involved in this cycle have been isolated and the sources of energy required for its operation have been identified in terms of reducing agents and 'high-energy' phosphate. These sources of ene… more

Antiproton Star Observed in Emulsion

Description: In connection with the antiproton investigation at the Bevatron we planned and carried out a photographic-emulsion exposure in a magnetically selected beam of negative particles. The magnetic system was identical to the first half (one deflecting magnet and one magnetic lens) of the system used in the antiproton experiment of Chamberlain, Segre, Wiegand, and Ypsilantis. The selected particles left the copper target in the forward direction with momentum 1.09 Bev/c.

[Ann Alden and new Ann Alden]

Description: Photograph of Ann Alden and a new Ann Alden posing for the camera. They are both standing in front of a plain backdrop. They are both smiling and holding up a gift with a sign that reads "Ann Alden." They are wearing dresses and accessories. Ann Alden was a stage name for Ann Barham Pugh.

Research and Development in the Field of Thorium Chemistry and Metallurgy. Monthly Progress Report for May 16 Thru June 15, 1955

Description: An internally heated chlorinator using a bed of graphite as a resistor element in contact with molten salt was shown to be feasible. An extended run was completed in an electrolytic cell demonstrating the feasibility of continuous operation. Other studies are reported on chlorination of thorium oxycarbonate and physical metallurgy evaluations of the Th produced. (T.R.R.)
