Low Energy Nuclear Physics : Second Annual Report for the Period February 1, 1959 to January 31, 1960
The general expression for the angular correlation between radiations produced in successive cascade transitions is derived by use of Racah algebra. The result is then specialized to the beta - gamma correlation and applied to two cases in which additional properties of the photon are specified, the circular polarization and the plane polarization. The prospect of testing time reversal and determining nuclear matrix element ratios by beta - gamma correlation measurements is explored using the nuclide Tm/sup 170/ as an example. The directional angular correlation between the 2.31-Mev beta and the subsequent 0.605-Mev gamma emitted in the decay of Sb/sup 124/ was measured as a function of the beta energy. The K-conversion coefficient of the 279-kev gamma following beta decay of Hg/sup 203/ was measured by comparing the x-ray and gamma intensities in a scintillation spectrometer. The measured valve of alpha /sub k/ = 0.195 plus or minus 0.014 indicates that the transition is M1 with E2 mixed to the extent of 63%. The angular correlation of the 107-1.24 Mev gamma cascade in Zn/sup 68/ following the decay of 68-min Ga/sup 68/ is shown. The Legendre polynomial expansion coefficients were deter-gular correlation in the decay of Sb/ sup 118/ was …

Organic Coolant Reclamation Annual Report : December 15, 1958 through December 14, 1959
Potential methods have been examined for the reclamation of high boiler arising from the degradation of polyphenol materials in use as reactor coolants and moderators. To define the chemistry of potential reclamation processes, model polyphenol compounds were used. These include biphenyl, o, m and p-terphenyl, and p-quaterphenyl. Emphasis has been on hydrocracking, redistribution (reaction with benzene), and partial reduction. Preliminary study has been made of the application these techniques to high boiler from Santowax-OM used in the OMRE. The three methods show promise but require detailed investigation to minimize carbon formation to locate optimum operating conditions,.

The Design and Uses of High Flux Research and Test Reactors
The need for thermal and fast neutron fluxes in the range of 1 to 5 x l0/ sup 15/ neutrons/cm/sup 2/(sec) for the production of heavy elements such as Cf/ sup 252/ and other special isotopes and for improving the quality of beam experiments, reactor materials testing work, and solid state research has led to plans for the construction of three ultra high flux research reactors. The designs of these and other high flux research reactors are based on the general technology of enriched tank-type reactors; however, they utilize the principle of separate fuel and moderator regions to achieve flux peaking in these regions. Thus, proposed designs take the form of an annular fuel region with internal and external moderating regions or an under moderated core with an external moderator or reflector. In such arrangements, the thermal flux peaks in the moderating regions and the fast flux peaks in the fuel region, which results in maximum fast and thermal fluxes per unit of power. Since most of the moderation of fast neutrons takes place outside of the fuel region, the thermal flux peaking depends on the number of fast neutrons leaking from the reactor core, which in turn depends on …

Corrosion of INOR-8 and Inconel Dissolver Components of the Fluoride-Volatility Process
The corrosion of INOR-8 and Inconel dissolver components used in the fluoride volatility process for the dissolution of zirconium with anhydrous HF in molten salts was investigated. Ten dissolution runs were made using simulated subassemblies formed from Zircoloy-2. The dissolver and components were made from INOR-8. Both the dissolver vessel and draft tube were examined several times during the series of runs. The solids which formed at different areas in the system were also analyzed. The results showed that the corrosion of the INOR-8 dissolver was greatest at the salt-off gas interface and at the HF gas inlet. Almost all of the corrosion took place during run 10 when no zirconium was present. Portions of the dissolver were cleaned after run 10 and sent to BMI for evaluation. The results of the Battelle metallographic examinations of the portions are included along with several photographs. The results with Inconel tubes in the copper-lined hydro-fluorinator confirmed the observations that the liquid gas interface areas were the most susceptible to attack.

Equilibrium Extraction Characteristics of Alkyl Amines and Nuclear Fuels Metals in Nitrate Systems. Progress Report No. V for the Period July 1 - September 30, 1959
Extraction of HNO3 by triaryl amine was studied by equilibrating equal volumes of aqueous and organic phases at 25C. At HNO3 concentrations of 2 to 10 N the acid in the organic phase in excess of that equivalent in the amine concentration was proportional to the concentration of HNO3 in the equilibrated aqueous phase. other workers report similar results with nitric acid and tri-n-octyl amine in benzene. Zirconium extractions carried out at 10g Zr/1 with 0.35 M TLA nitrate in toluene showed a fourth power dependence of EZR on HNO (aq) over the range 2 to 10N. Maximum distribution ratios calculated from samarium scouting experiments using amines in kerosene were about 5 x 10(-3) for Primene JMT, 10(-4) for TLA, 10(-5) for S-24, and less than zero for DTDA. Distribution rations in the extractions ranged from ERu = 0.12 for 0.35M TLA shaken with an initially new 2N HNO3 solution for 15 minutes. Data on Zr and Ru standardization in TLA solution for spectrophotometric analyses are included.

Sampling the Upper Atmosphere for Particulate Matter. First Quarterly Progress Report, June 15 to September 25, 1959
An analysis to screen the various particle-collection systems which might be used for sampling the upper atmosphere with a rocket sampling vehicle has been undertaken. Although the current model of the Goetz Aerosol Spectrometer is not suitable, a high-flow-rate sampler of this general type, if it can be designed, appears promising. The design of such a sampler will be undertaken in future work. If a workable design is possible, this method would appear to be the most promising of all.

Operation Pre-Gnome: Seismic Data from Natural Phenomena and High-Explosive Tests Near Carlsbad, New Mexico
Formulas derived from earlier work satisfactorily predicted low frequency ground effects resulting from the Pre-Gnome explosions, but they not predict high accelerations associated with high frequency ground waves. The Pre-Gnome experiments taken since indicated that accelerations and ground amplitudes are proportional to the explosive charge, but physical conditions limit extrapolation on this basis to relatively low yields. Predicted accelerations resulting from the 10 kt Gnome explosion in potash mines eight or more miles away will be somewhat less than from routine blasts in the mines. The compressional wave speed in the salt stratum of the area is about 14,000 feet per second.

Unitized System of Image Intensifiers Using Fiber Optics. Progress Report for July to October 1959
Phase 1 of the AEC contract AT(30-1)-2176 consists in developing a light intensifier which includes a fiber optic faceplate in the output end. The vacuum side of the faceplate shall be coated with an aluminum-backed P15 phosphor and shall have an effective radiating diameter of 1". The execution of this phase depends primarily upon developing a satisfactory technique for sealing the fiber optic faceplate to a suitable container. During the delay which has occurred between the ordering and the actual delivery of the components, a program was set up to develop the sealing technique and a satisfactory technique was evolved. Phase II entails the development of a light intensifier tube with a fiber optic faceplate on both the input and output. The photocathode fiber optic faceplate arrived and was found to have one small area which was not completely vacuum tight. The manufacturer is correcting the problem.

The Helium Cooled Loop in the GETR
The General Electric Test Reactor (GETR) facility is designed to irradiate the fuel specimens in a helium-cooled environment at 800 degree F and pressures from 315 to 400 psig. Thermal neutron fluxes in the fuel are of the order of 3 x 10(13) mv and the induvial test pieces, of which there are three in each facility tube, generate five kilowatts at heat fluxes slightly over 200,000 Btu per hour per square foot. Five facility tubes are provided in the reactor pool. Separate coolant lines are brought out from each facility tube to the instrumentation. The lines are then joined into one inlet and one outlet header line and are so connected to the compressors and the balance of the equipment. Axial-flow rotary compressors are used to circulate the coolant gas. Each of the facility tubes is provided with a movable cadmium neutron shutter and with suitable instrumentation and equipment to allow individual adjustment of operating conditions.
