III. Crystalline Complexes of Bis(Di-2-Ethylbutylphosphinyl) Methahe With Uranium(VI) Nitrate and With Thorium Nitrate

Description: Technical report. From Abstract : "Bis(di-2-ethylbutylphosphinyl)methane, EBDPM, forms complexes with uranium (VI) nitrate and thorium (IV) nitrate in which EBDPM acts as a bidentate ligand and the nitrato groups appear to be coordinated. The complex with uranium (VI) is a monomer, UO2(NO3)29EBDPM), while the complex with thorium in a dimer, [Th(NO3)4]2(EBDPM)3. Both complexes are of high thermal stability."

Separation and Spectrophotometric Determination of Rare Earths

Description: Technical report. From Summary : "At the present time arsenazo appears to be widely used for the spectrophotometric determination of rare earths. Unfortunately, the method is not selective. The separation of rare earths and yttrium from interfering elements has been studied, and the following method has been proposed. Rare earths are precipitated as fluorides using fluorides using calcium fluoride as the carrier. Thorium and zirconium are removed by extraction with thenoyltrifluoroacetone (TTA) in xylene at pH 1.3. Small amounts of residual aluminum, iron, etc. are removed by extraction with 8-quinolinolchloroform at pH 4.5. Rare earths are separated from calcium by TTA extraction at the same pH, and they are then back-extracted into 1 M nitric acid. After evaporation of the solution, the rare earths are determined spectrophotometrically with arsenazo."

The Enhancement of Acidity of Very Weak Acids in Tertiary Butyl Alcohol

Description: Technical report. From Abstract : "The acidity of a solution of acid, HX, and salt, MX, is affected by both the concentration of X- and M+ owing to incomplete dissociation of the salt, MX. it was possible to increase the acidity of a solution of 2,6-di-tert-butylphenol - tetrabutylammonium 2,6-di-tert-butylphenolate relative to a dilute solution of tetrabutylammonium hydroxide by increasing the tetrabutylammonium bromide content. This indicates that the dissociation constant of the hydroxide base is sufficiently large that extensive dissociation occurs in dilute solutions. The addition of tetrabutylammonium bromide is therefore recommended as a general method for increasing the acidity and improving the titration characteristics of extremely weak acids."

Study of Metal-1.10-Phenanthroline Complex Equilibria by Potentiometric Measurement

Description: Technical report. From Abstract : "The silver-1,10-phenanthroline system has been studied and the stability constants determined for the 1:1 and 2:1 complexes using the silver electrode. This known system was then used to study the complexes of 1,10-phenanthroline with other metals. The log βn values found for the over-all stoichiometric stability constants are as follows: Ag, 5.02, 12.07; Mn, 3.88, 7.04, 10.11; Cd, 5.93, 10.52, 14.30; Zn, 6.83, 12.05, 16.92. The stoichiometric stability constants determined for copper are log k2 = 6.42 and log k2k3 = 11.05."

The Scandium-Yttrium and Scandium-Zirconium System

Description: Technical report. From Abstract : "The scandium-yttrium and scandium-zirconium were studied by thermal and x-ray methods. Both systems are characterized by complete solid solubility in the low temperature hexagonal form and in the high temperature bcc form. In the Sc-Y system, there is a minimum in the solidus at 50 at. pct and 1365°C, while the solidus in the Sc-Zr system follows a nearly straight line relationship between the melting point of scandium and zirconium. There is a minimum in the temperature of transition from hexagonal to bcc in the Sc-Y system at 43 at. pct Y and 1175°C; while the temperature of transition is raised in the Sc-Zr system to a maximum of 1415°C at 30 at. pct Zr."

Technical criteria and bases for a zirconium-tubed K Reactor

Description: The criteria contained in this report have been established to provide the technical bases for the design modifications involved in the K-Reactor tube replacement. The ultimate intent of these criteria is to provide the basic technical data and concepts to assure: technical feasibility and operability of the reactor system as modified; operation of the reactor and its services to minimize nuclear and radiation hazards; and appropriate lifetime of the reactor and its service facilities as modified. The criteria are appropriately broad and may not contain all the data necessary to accomplish detail design. The information contained herein shall serve as a basis for evaluation and approval of all portions of the modification relating to the process as indicated in the above three points.

Measured vs calculated river {Delta}T

Description: River temperature traverse data within and just the plant boundary are quite limited. For this report, traverse temperatures were calculated by first averaging the depth measurements vertically at each traverse point, and then weighing the average for the cross section by the depth at each point and the span between points. Calculated {Delta} T`s were determined by dividing the total reactor power level above the traverse line by the river flow, with the appropriate factor to obtain the correct units. No attempt has been made to apply corrections for atmospheric effects or the diurnal cycle.

Production test IP-541-A reactor effluent studies

Description: The objective of this test is to determine the concentrations of radioisotopes in the effluent from a Zircaloy tube and an aluminum tube when both are charged with Zircaloy clad fuel elements and cooled with deionized water. Deionized water is currently being used as the coolant for a Zircaloy and an aluminum tube at KE Reactor. To date the fuel for these tubes has been aluminum clad. Progress is being made in assessing the relative importance of fuel element film and tube film on the radioisotope content of the effluent as well as the contribution of aluminum corrosion to effluent activity. However, there is no information available at present on a channel in which corrosion is reduced to a minimum. It is anticipated that the data supplied by this test will permit a complete evaluation of the variables delineated above.

Performance test, Additional pumping capacity, 181-D

Description: The existing pumping capacity and piping intertie arrangement between 181-D and 183-DR makes it necessary to continuously cross-feed treated water from 183-DR flumes to insure adequate reactor flow to 105-DR to meet present production levels. This arrangement means that pumping equipment in both 181-D and 183-D is kept in use to the extent that repair or productive maintenance work must be accomplished during reactor outages, or production levels must be reduced to release a pumping unit during operation.

Results of production test IP-528-I, F Reactor high tank drawdown test

Description: A continued decrease in flow measured during the periodic high velocity flushes indicated that corrosion buildup in the high tank discharge lines was deceasing backup flow to the reactor. An accurate determination of the high tank flow rate to the reactor was needed to evaluate present back-up adequacy. Riser pressure and flow rate were also measured with throttled high tank discharge lines to establish the low flow and critical portion of the reactor hydraulic characteristic curve. This report presents the numerical results of the test conducted on October 4, 1962.
