A PRELIMINARY SURVEY OF SOME FLUORIDE COMPOUNDS - II
These two parts were issued separately, but are cataloged as a unit. The two compounds Na/sub 4/U/sub 3/F/sub 17/ and Na/sub 3/Th/sub 2/F/sub 11/ were found to have a face-centered cubic structure. From parameter dimensions and intensity values these two compounds appear to be isomorphous. Na/sub 5/U/sub 3/F/sub 17/ has an identical cell size with alpha -Na/sub 2//UF/sub 6/. A group of three compounds (Rb/sub 2/ThF/sub Rb/sub 2/ZrF/sub 6/, and CsZrF/sub 6/) were reliably identified as being uniaxial by use of their optical properties. These compounds were tentatively indexed on the basis of data obtained from powder x-ray spectrometer patterns found to best fit a hexagonal unit cell. (W.L.H.)

An Alpha Survey Radiac for Field Use
Abstract: An alpha survey radiac employing a photomultiplier tube and scintillation detector has been developed. The instrument utilizes transistor circuitry and operates from two standard flashlight batteries. Four linear ranges are provided with full scale indication on the highest range corresponding to 10,000 g /m2 Pu2 39. The instrument was designed with .a separable probe and a telescoping extension for easier ground monitoring. A thorium metal source is attached to the instrument housing for checking instrument calibration in the field. The device conforms satisfactorily to the military requirements for altitude, humidity, vibration, shock, and storage. The operational battery life is in excess of 40 hours. Instrument error at low temperatures slightly exceeds the 20% accuracy requirement; however, adequate measurements are readily made by using the thorium check source to provide a check point. Instrument response to low energy X-rays is excessive. However, tests indicate that a simple lead filter will eliminate this difficulty.

Braze Ring Mold for Sintering & Casting
Technical report of an investigation to determine a suitable material for sintering and casting of braze rings. Braze rings afford an excellent means of preplacing braze alloy on tube to head joints of radiators, heat exchangers, and similar applications. A cast ring is especially desirable because of its increased strength. Previous efforts at casting had used welding grade carbon blocks with the desired ring cavities machined into their surface. Conclusion: Stackpole grade 331 electro-graphite provided the best results of the materials investigation. It is hard and more readily machinable with conventional tools than other grades. Carbon, in general, proved to be more satisfactory especially due its ease and speed of fabrication.

Scattering of K<sup>+</sup> Mesons Off Protons
The total K/sup +/-p cross section was measured at the three K/sup +/- meson energies 175 er inch per 25, 225 er inch per 25, and 275 er inch per 25 Mev and the differential scattering cross section was measured at 225 Mev. The K/sup +/-p nuclear force was shown to be repulsive from the observed constructive interference with Coulomb scattering. The differential c=oss section was otherwise isotropic and could arise from either pure S-wave or pure P- wave scattering. Subtracted dispersion relations were applied to these data and the rest of the available K proton scattering data. The statistical errors on the data were found to be too large to determine the K-hyperon relative parity. However, if the K DELTA and K SIGMA relative parities are assumed to be the same, then if the coupling were scalar, the coupling constant g/sup 2/4 pi would be less than 0.6; if pseudoscalar, less than 10.

Uranyl Sulfate-Dovex 21K Anion Exchange: A Literature Survey, Review of Preliminary Data and Outline of a Proposal Experimental Program
The system Dovex 21K and aqueous uranyl sulfate solutions were studied in the solution compositions range: 0-0.005 mol/liter uranyl sulfate, 0.15 mil/liter total sulfate, 0.02 mol/liter H2SO4 (pH 2).It is shown that UO3SO4 and/or UO2(SO4)2-/2 are sorbed on the resin to form R2UO2(SO4)2. It is surmized that these same species are also involved at high uranyl concentrations and pH 2 it is suggested that U2O5SO4, U2O5(SO4)2-/2, and R2U2O3SO4 species may be involved.

HOT CELL DEMONSTRATION OF ZIRFLEX AND SULFEX PROCESSES. Report No. 3
ABS>Hot cell demonstration of the Zirflex decladding process coupled with a modified Purex solvent extraction process was completed using specimens of Zircaloy-clad UO/sub 2/ irradiated to levels of 6150-14,600 Mwd/TU. Soluble losses of uranium and plutonium to the decladding solutions were about 0.05%. Centrifugation of the decladding solution is probably necessary to remove up to 1% of the UO/sub 2/ present as fines resulting from the fracture of low (93 to 95%) density pellets; high (96%) density pellets produced few fines. Approximately 5 hours were required to dissolve the UO/sub 2/ core material (14,000 Mwd/TU) in 4M HNO/sub 3/ versus 6 to 7 hours for unirradiated pellets to produce a solvent extraction feed of 100 g U/l and 3M HNO/sub 3/. Gamma decontamination factors for uranium in the Purex CU stream and plutonium in the BP stream were increased by factors of 2 to 10 from the normal 1.3 x 10/sup 3/ and 2.1 x 10/sup 3/, respectively, by pretreatment of the solvent extraction feed with dincetyl monoxime or its degradation product, oxalic acid. Preliminary data indicate radiation damage degrades the solvent, 30% TBP diluted with Amsco 125- 82, upon one pass through the mixer-settler banks with feed solutions irradiated …

Stress Analysis of the PM-2A Reactor Vessel
The stress analysis performed on the PM-2A reactor vessel and cover is discussed. The maximum combined stress (51,000 psi) occurred in the studs after reaching steady-state conditions. A fatigue analysis indicated that this stress could be safely applied 2500 times, and since the studs do not approach 2500 cycles from initial stud tightening to steady-state conditions, they should not suffer any fatigue damage.

Pressure-Volume-Temperature Measurements on Solids
From abstract: "The results of recent measurements on the equations of state of sodium and xenon are discussed. The experimental data for each of these are analyzed to show that the isothermal compressibility is solely a function of volume within experimental accuracy. The basic differences between the low temperature PV relationships for sodium and xenon are shown to be easily understandable in terms of the elementary theories of these substances. The range of experimental pressures (to 20 kbars) and temperatures (20°K to the triple point) is sufficiently great so as to produce significant changes in the lattice thermal properties in each case. These changes are indicated through the use of zero pressure heat capacity data in combination with the equation of state data to calculate the volume and temperature dependence of the Debye Θ. The result is quite spectacular for xenon, where a pressure of 20 kbars roughly doubles ΘD."

Cratering Experience With Chemical And Nuclear Explosives
Over the past 13 years a considerable body of data on explosive cratering has been developed for application to nuclear excavation projects. These data were obtained from some ten cratering programs using chemical explosives (TNT or nitromethane) and seven nuclear cratering detonations. The types of media studied have ranged from marine muck to hard, dry basalt, although most effort has been devoted to craters in NTS desert alluvium and basalt. Considerable effort has also been devoted to the study with chemical explosives of the use of linear explosives and rows of point charges. This paper is intended to be a summary of these data and a statement of the understanding which has been developed from them.
