Critical Experiments With 2.09% U$Sup 235$-Enriched Uranium Metal Plates in Water
Experiments were performed with 2.09% U/sup 235/-enriched uranium metal plates in a light-water-moderated and -reflected assembly. Each plate was 30 in. long, 31/8 in. wide, and 1/4 in. thick and contained 7.09 kg of uranium. In the first assemblies the plates were arranged in rows with edges adjacent, and the spacing between rows was varied from 5/8 to 1 1/8in. The optimum spacing was about 7/8 in. With the spacing between rows maintained at 7/8 in., the spacing between the edges of the plates was varied from 0 to 5/8 in. The optimum spacing between edges was 5/16 in. The minimum critical mass in these assemblies was 6.74 kg of U/sup 235/. (auth)

Zirconium Highlights
The effect of hot-worked thickness on the corrosion behavior of atmosphere-melted Zircaloy-2 is discussed. Hydrogen pickup upon etching Zircaloy- 2 Zircaloy-3, and properties of vacuum-cast Zircaloy-2 and the fabrication of special Zirccaloy shapes are presented. A hardness converison chart for annealed zirconium and zirconium alloys is included. (J.E.D.) The useful properties of the tungsten wires used in the incandescent lamp and ra dio tubes industry are ensured by adding about 1% of various ingredie (e.g., K, Na, Al, Si compounds) to the tungstic acid and producing metal powder and compressed rods. During the sintering of these rods, the additions are evapo rated to such an extact that finally the concentration of foreign atoms remains only 10/sup 5/. According to the investigations, the warm hardness values of these tungsten pieces is determined by the traces of impurities. In order to investigate the influencce of the various kinds of atoms, an apparatus was built for the determination of half-micro warm hardnesses of various kinds of tungsten metals in the temperature interval 20 to 800 deg C The tungsten wires made with additions containing Si had an average hardness H/sub V/ = 250 at 800 deg C, while the wires without such additions …

EFFECT OF DENSELY IONIZING RADIATIONS ON DRY PREPARATIONS OF LYSOZYME, TRYPSIN, AND DNase
The effects of beams of protons and alpha particles from the 60-inch cyclotron and beams of accelerated nuclei of heliuan-4, carbon-12, oxygen-16, and neon-20 from the linear accelerator on thin films of dried enzymes were measured. The experimental apparatus is described and results are presented graphically. (C.H.)

U$sup 233$ Purification and Metal Production
Two problems are encountered in U/sup 233/b purification and metal production. One is high alpha activity, which requires that all operations be enclosed. The other is beta-gamma activity originating from U/sup 232/ present in U/sup 233/ as a contaminant. This, the immediate daughter of U/sup 232, produces a chain of strong beta-gamma emitters, which make shielding and thorium separation procedures necessary. Chemically impure solutions of metal fabrication residues are separated from trace amounts of thorium isotopes by cation resin exchange in shielded equipment. The short-lived thorium daugters are allowed to decay, after which beta-gamma activity is low enough to permit chemical purification in unshielded equipment. The U/sup 233/is chemically separated from nonradioactive contaminants by precipitation as UO/sub 4/- xH/sub 2/O, which is calcined to U/sub 3/O/sub 8/. The U/sub 3/O/sub 8/ is reduced to U0/sub 2/ and converted to UF/sub 4/. Pure metal is prepared by bomb reduction of the UF/sub 4/ with calcium as the reducing agent. Residues from the chemical purification steps, reduction, metal fabrication, and ganeral cleanup are processed into nitrate solutions, solvent extracted, and concentrated for recycle. Ion exchange, precipitation, reduction to metal, and casting all have effect upon the thorium isotopes and their daughters, resulting …

Irradiation of Prototype CP-4 (EBR-I) Reactor Fuel Slugs in the CP-3' Goat Hole. Final Report of Metallurgy Division Program 6.1.1.
Experiments are described which studied the effect of irradiation upon small U/sup 235/ cylinders simulating in size those designed for thc initial CP-4 (EBR-I) fuel loading. Qualitative similarities between thermal cycling and irradiation effects were found, but none of the three types of inaterial tested were entirely dimensionally stable. (auth)

Critical Parameters for Poisoned Annular Cylinders Containing Aqueous Solutions of U$Sup 23$$Sup 5$
Experiments were performed to determine the critical parameters of aqueous solutions of 93.2% U/sup 235/-enriched uranyl fluoride contained in cylindrical annuli formed by various combinations of aluminum cylinders varying in diameter from 2 to 30 in. In all of the experiments the inside cylinder was lined with a 20-mil-thick cadmium sheet and filled with water to a height of 48 in., and in some experiments a water refiector was used on the sides and bottom of the outside cylinder. The data indicate that for the solution having an H:U/ sup 235/ atomic ratio of 50.4 the critical infinitely high reflected annulus would have a minimum thickness between 2.5 and 3 in., while the unreflected annulus would have a thickness between 3.75 and 4.5 in. The corresponding thicknesses for the solution having an H:U/sup 235/ atomic ratio of 309 would be between 3.5 and 4 in. for the refiected annulus and between 4.5 and 5.5 in. for the unreflected annulus.

SALT-LUBRICATED HYDRODYNAMIC JOURNAL BEARING TESTS NOS. 1 AND 2
The results of the hydrodynamic journal type bearing phase of the salt- lubricated bearing development program at Oak Ridge National Laboratory are given. One test each of two hydrodynamic journal type bearings constructed or INOR-8 versus INOR-8 was performed with molten salt #130 (62 LiF, 37BeF, 1 UF/sub 4/ mole %) at 1200 deg F as the lubricant. The first bearing operated for twenty minutes and the test was terminated due to seizure of the bearing and journal. The second bearing operated for 500 hours during which fifty-seven stopstart tests were performed and hydrodynamic lubrication was attained for extended periods at 1200 rpm and 200 lb radial load. Termination of the test was as scheduled at the completion of 500 hours of operation. Plans are also included for fur her testing. (auth)

Efficiencies and Photofractions for Gamma Radiation on Sodium Iodide (Thallium Activated) Crystals
The efficiencies and photofractions for monoenergetic garnma raps incident on sodium iodide (thallium activated) crystals have heen calculated by the Monte Carlo method. The calculations have been carried out for broad parallel-beam sources, point sources on the crystal axis, and disk sources, all for photon energies of 0.279, 0.861, 1.33, 2.82, and 4.45 Mev. The crystals considered were right circular cylinders with radii of radius, heights of 1.0, 2.0, 4.0, and 8.0 inches. The effect of the escape of annihilation gammas from the crystal was taken into account in the Monte Carlo calculation; however, no correction was made for escape of bremsstrahlung from secondary electrons and positrons. This latter correction is of importance only at the largest energies and for the smallest crystals where it affects the photofractions by a few per cent. (auth)

INSTALLATION AND INTERFERENCE PROBLEMS IN REACTOR INSTRUMENTATION SYSTEMS
Reactor control instrumentation systems may be subject to a variety of extraneous signals. Five types are discussed: signals involving high-frequency components which may gain access to critical circuits through wiring that lacks suitable RF filtering; current signnls due to mechanical shocking or flexing of cables; extraneous ion chamber signals, including displacement currents due to fluctuations in the polarizing voltage, as well as currents caused by mechanically induced changes in ion chamber capacity; signals whose origin is magnetic induction into cable loops; and signals involving magnetic induction and ohmic induction into auxiliary loops created by multiple ground connections. The emphasis is placed on magnetic induction and means of eliminating it. (auth)

HRP-CPP: Dissolution of Zirconium and stainless steel corrosion product oxides
Dissolution methods were developed to permit representative sampling of the slurry of corrosion and fission products collected by the HRT chemical process-ing plant. The procedure selected for HRT-CPP application was to use 15 ml of 10.8 M H/sub 2/SO/sub 4/ per gram of solids with agitation by boiling in a tantalum-lined dissolver. (auth)
