The iodine species formed either by adding hypochlorite to a basic iodide solution or by adding triiodide to sodium hydroxide, was identified as hypoiodite ion. The absorption spectrum of IO{sup -} was investigated in the wavelength range from 450 m{micro} to 280 m{micro}. The kinetics of the reaction I{sup -} + ClO{sup -} = IO{sup -} + Cl{sup -} was studied spectrophotometrically in alkaline solution. The forward rate law was found to be d(IO{sup -})/dt = k(I{sup -})(ClO{sup -})/OH{sup -}. At 25 C and an ionic strength of 1.00 M, k is 61 {+-} 3 sec{sup -1}. It was found spectrophotometrically that for certain ratios of the initial iodide to hydroxide concentrations, there was evidence of the presence of I{sub 3}{sup -}, I{sub 2}OH{sup -}, and I{sub 2}O{sup 2-} along with IO{sup -}. The equilibrium constants between IO{sup -} and these three species were evaluated by a graphical method. The formal potential of the cell: Pt:H{sub 2}:1 M NaOH : 1M NaOH, KI, NaIO : Au was found to be 1.297 v at 25 C. The equilibrium constant, K{sub 2} = (I{sub 3}{sup -})(OH{sup -}){sup 2}/(IO{sup -})(I{sup -}){sup 2}, of the reaction IO{sup -} + 2I{sup -} + H{sub 2}O …

Report discussing tests to determine the aerodynamic characteristics of a model of a 45 degree swept-wing fighter airplane and to determine the loads on attached stores and detached missiles. An investigation into aileron-spoiler effectiveness, aileron hinge moments, and the effects of wing modifications of aerodynamic characteristics was also carried out at various Mach numbers. Results are presented, but caution is provided in regards to extrapolating results from the model onto a full-scale aircraft.

Failures of standard fuel element jackets (1245 aluminum alloy) after relatively short Hanford reactor exposures are occurring at high reactor power levels. Metallographic examination of fuel element jackets from short exposure ruptures shows the cause of failure to be rapid intergranular corrosion. This type of attack has been reproduced in laboratory tests by exposure to water at temperatures above 200 C, or to steam at temperatures higher than 300 C. Flow disruptions due to misalignment of the fuel elements within the reactor process tube, worn tube ribs, etc., are believed to cause the high local jacket temperatures necessary for the occurrence of intergranular corrosion.

This document consists of three photographs of ruptured fuel elements. The position, date charged, date failed, exposure, power, lot and failure type are given for tube 3655-KE, tube 4153-KE, and tube 3849-KE. (GHH)

This document details activities of the irradiation processing department during the month of May 1958. A general summary is included at the start of the report, after which the report is divided into the following sections: Research and Engineering Operations; Production and Reactor Operations; Facilities Engineering Operation; Employee Relations Operation; and Financial Operation.

This is the monthly report for the Hanford Laboratories Operation, May 1958. Reactor fuels, chemistry, dosimetry, separation processes, reactor technology, financial activities, biology operation, physics and instrumentation research, employee relations, operations research and synthesis operation, programming, radiation protection, and laboratory auxiliaries operation area discussed.

The purpose of this supplement is to authorize adjustment of the fuel loading to maintain a balanced longitudinal flux distribution in the region loaded for this Production Test.

Modifications to the 100-K water plant will be made, under Project CG-775, to increase total process water flow rates to 175,000 gpm or greater. Included in the modifications will be the installation of new pump impellers for the primary and secondary process water pumps located in the 190-K Buildings.

With higher power levels and probably higher river temperatures, the forthcoming warm water season is expected to impose bulk outlet temperature limits, with consequent production losses, on all Hanford reactors to an even greater extent than last year. The problem has received the attention of a number of management and engineering personnel, but the basis for this study was a letter originating in the Production Operation suggesting two alternate schemes for increasing the flow of process water to the rear face piping, thereby reducing bulk temperatures for a given power level. The purpose of the suggestions was to provide an interim solution to the problem pending I & E loadings. Loading with I & E slugs will increase reactor flows to some degree, depending on the actual slug dimensions used, and will probably result in encountering other limits than the B.O.T. limit. The applicable period for study was therefore taken to be this summer only, since I & E loadings are expected to begin in June or July at 105-D and during the fall at 105-F. The Managers, D and F Reactor Operations, requested Plant and Industrial Engineering Operation to investigate and compare the feasibility and applicability of the suggested …

The octant monitors are an improvement over the early sub-pile flux monitors, but they still do not monitor the flux in the active zone of the reactor. Chambers located within the pile active zone would give the desired information but the inpile environment is too severe to allow a reasonable life for these chambers. A beam hole monitor is suggested to provide the desired flux monitoring. The problem of reactor flux monitoring is discussed. The beam hole monitors have the advantage of providing adequate active zone coverage. Calculations were made to show the neutron current and current density at the chamber location as a function of the collimation of the detector assembly. These curves show the present sub-pile and octant monitors are sensitive primarily to the flux in the pile reflector rather, than in the active zone. The beam hole monitors can be made sensitive to the active zone flux only. Sufficient chamber current can be obtained to operate available trip circuitry. It is recommended that experimental work be started to prove out these beam hole monitors so any new reactor program may take advantage of them and that the monitoring of present piles can be improved.

The performance of I & E fuel elements under the original tests{sup 1} was such that they are now being charged at C Reactor on a production basis. Data obtained from the original test, however, were not sufficient to indicate long term corrosion effects of the use of these elements, nor to accurately define their operating characteristics. It is the intent of this test, therefore, to provide for long term corrosion monitoring in tubes charged with and without water-mixing pieces; and to obtain the required operating data to refine the operating characteristics of this fuel upon which power limits are based.

This report contains brief discussions on reactor physics on: metallurgy; production piles; separation plants; plutonium recycle program; and cross section measurements.
