Thorex Pilot Plant ; System for Concentrating Second Uranium Cycle Product
A system for concentrating uranyl nitrate solutions was designed and installed in the Thorex Pilot Plant. A total of 16,060 g of uranium was concentrated in the system in 68 batch runs. A total of 14,400 g total uranium (14.180 g U/sup 233/) was recovered as product suitable for shipment. Uranium loss to the evaporator condensate was 0.03% of the total uranium processed. The material balance across the system was 98.4%. The average concentration of uranium in the evaporator feed solution was 29 g/liter; the average concentration in the evaporated solution was 298 g U/liter and in the product solution was 199 g/liter. Radiation readings of bottles containing product solutions were taken with a hard-shell cutie pie immediately after each run, and these readings ranged from 35 to 1100 mr/hr. The radiation levels of the bottles of product solution shipped averaged 78 mr/hr. Bottles of product solution reading in excess of 300 mr/hr, maximum allowable for shipment. were reprocessed in the second-cycle solvent extraction system (Thorex) and reconcentrated. The products from seven runs had radiation levels in excess of 300 mr/hr at the time of concentration, or the activities had grown to that level by the time of shipment. The …

The Decontamination of Reactor Cooling Water with Aluminum
The discharge of cooling water from the Hanford reactors introduce radioactive contaminants to the Columbia River. These materials may subsequently bring about exposure to human populations either through the direct use of the water for sanitary purposes or transfers of the radioisotopes into the food chains. It is therefore desirable to keep to a minimum the amounts of radioisotopes released to the river.

Penetration Effects in Magnetic-Dipole L-shell Internal Conversion
Internal-conversion coefficients may be thought of as consisting of two parts: a usually dominant part which depends only on the atomic number and the nuclear transition energy, and a usually small part depending explicitly on nuclear transition matrix elements. This latter part arises from the penetration of the converting atomic electrons within the transforming nucleus.

A Simple Theory of the Process P+P → D+W+
The discovery of the vector meson which mediates the weak interactions, W,1 would be of extreme importance for weak interaction physics and for field theory in general. The W, if it exists, will be made in a variety of processes such as v+N →W+ + e- + N, or n- + P →W- + P, or, as studied in this note, P + P → D + W+. The W couples to leptons with a dimensionless constant [constant not transcribed] where G is the Feral constant defined t=so that [constant not transcribed]. Thus for [equation not transcribed] and the smallness of this constant is, evidently, what makes any of the above processes difficult to detect. The W may have a variety of decay modes.

Some Further Remarks on Beam Current Measurements in the AGS
A previous report on this subject (Brookhaven National Laboratory, AGS Internal Report, ECR-4) described in detail the methods of measuring the injected and accelerated proton currents in the Brookhaven AGS up to May 1961. At that time the accelerated current was measured by extracting the bunch frequency component of the signal given by a pair of radial position observation electrodes. The injected current was also determined by the signal induced on a similar pair of radial position electrodes. Absolute values were then determined from machine parameters and a wire measurement of the electrode sensitivities. Linac currents, however, were measured with transformers, calibrated by putting known current pulses through a single turn loop. As described in ECR-4, a crude current transformer was placed on the AGS ring and cross-calibration measurements were carried out using a half turn injected beam. The pickup electrode value was then found to be about 10% higher than that given by the current transformer. This amount of disagreement was within the estimated accuracy of the measurements and calibrations used at that time.

Interim Report: Investigation of Ultrasonic Decontamination
The purpose of this investigation is to make a preliminary study and evaluation of the application of ultrasonic equipment and associated handling equipment to the problem of decontaminating reactor tube dummy pieces. Reactor Section is currently planning the construction of batch process nitric acid facilities for dummy decontamination. It was felt that use of ultrasonics together with a solution less corrosive than nitric acid might provide adequate decontamination at lower project cost than the presently proposed nitric acid facilities. This report gives the progress of the investigation to date.

Harmonics suppression in electromagnets with application to the ALS storage ring corrector magnet design
This memo presents an analytical development for prediction of skew harmonics in a iron core C-magnet to due arbitrarily positioned electromagnet coils. A structured approach is presented for the suppression of an arbitrary number of harmonic components to arbitrarily low values. Application of the analytical harmonic strength calculations coupled to the structured harmonic suppression approach is presented in the context of the design of the ALS storage ring corrector magnets.

Grain boundary concentration mapping by the CoRaD technique. [Cu--0. 074 to 1. 82 percent U; Count Rate Discriminator (CoRaD)]
Copper and uranium were melted together in an electron beam furnace, rolled and vacuum annealed at 900/sup 0/C. Several samples were examined, varying in uranium content from 0.074 to 1.82 wt. percent. Each sample was mounted in a resin and polished for optical microscope and electron microprobe work. These samples, when viewed under an optical microscope exhibited three distinct phases: featureless grain surfaces, a light gray phase in the grain boundaries, and an occasional dark gray phase also found in the grain boundaries. It is shown that the Count Rate Discriminator technique used in coincidence with a target current detector provides a powerful tool to map and to determine quantitatively the distribution of minor phases in grain boundaries and inclusions.

Use of geochemical-equilibrium computer calculations to estimate precipitation from geothermal brines
The Helgeson-Herrick geochemical code was used to calculate the solubility of NaCl, KCl, and KCl-NaCl in water and to predict which minerals will precipitate from Salton Sea Geothermal Field brines. The code's predictions of sulfide-silicate precipitation from the Magmamax No. 1 brine are in good agreement with field tests of scaling, although the observed sulfide-silicate scale matrix is in amorphous form, rather than the crystalline form predicted by the code. The code's predictions of scale precipitation from wells with different brine compositions are also in good agreement with field tests. The code appears to be a useful screening tool, despite reservations about the use of purely thermodynamic predictions in systems with important kinetic constraints. Several ways to improve and apply the code in the future are suggested.

Fundamental studies of metal fluorination reactions. Annual progress report
Solid-state electrochemical methods are being used to determine structural, thermodynamic, and transport properties in materials pertinent to the fluorination of metals at elevated temperatures. The solubility and diffusivity of fluorine in solid metals (initially nickel) are being studied by a potentiostatic electrochemical procedure by which changes in an impressed cell voltage induces changes in the activity of fluorine at a metal/electrolyte interface while the recording of the resulting cell current as a function of time can be interpreted to yield the desired quantities. Defect structures in metal fluoride compounds (initially NiF/sub 2/ and PbF/sub 2/) are being studied through measurements and interpretation of the electrical conductivity. The variation in the conductivities of the pure and impurity-doped compound as a function of fluorine activity can be interpreted to establish the partial ionic and electronic conductivities of the compounds, and the concentrations and mobilities of the carriers. Finally, a CaF/sub 2/-electrolyte probe (gauge) is being developed for the measurement of fluorine activities in gases at elevated temperatures. The literature has been searched and studied. Experimental materials have been ordered and two high-temperature electrochemical systems have been constructed and tested. The electrical instrumentation has been tested and calibrated. A porous graphite electrode was …
