The Solubility of Tributyl Phosphate in Aqueous Solutions (open access)

The Solubility of Tributyl Phosphate in Aqueous Solutions

Report describing a study regarding the solubility and related properties of tributyl phosphate (TBP), which has lower solubility in water than most uranium solvents. Pure TBP and TBP in an inert diluent were tested for solubility in water, several nitric acid solutions of varying concentrations, and other solutions typical of process streams. For TBP-diluent-water system tests, equilibrium water content in organic phase was found.

Viscosity and Settling Rates of TBP Waste Metal Slurries as a Function of Shear (open access)

Viscosity and Settling Rates of TBP Waste Metal Slurries as a Function of Shear

This report follows work that is meant to determine the settling rate and viscosity of Hanford Waste metal slurry as a function of prolonged agitation and shear, and to repeat these determinations on a synthetic incubated material similar to that used in the acidification studies, HW-18367, and to make a direct comparison between the genuine and simulated wastes.

Decontamination of the KER Rupture Experiment Loop Test Series B - Tests No. 1 and 2 (open access)

Decontamination of the KER Rupture Experiment Loop Test Series B - Tests No. 1 and 2

The first series tests in the KER-REP-1 loop proved that a fisssion product contaminated loop could be decontaminated to a safe level for contact maintenance. The second series of tests ere scheduled for a more thorough evaluation of these processes includes specific decontamination factors, process corrosion rates, loop activity reduction factors (loop decontamination factors), and any preferential decontamination which may be present.

Specific Gravity of Aluminum Nitrate Solutions (open access)

Specific Gravity of Aluminum Nitrate Solutions

Aluminum nitrate solutions are used as salting agents in the redox process and frequently in organic-aqueous extractions in the laboratory. Determination of specific gravity is a convenient means of estimating the concentration of such solutions. However, where an aluminum nitrate solution has been prepared by dissolving aluminum hydrate in nitric acid, the ratio of nitrate to aluminum may intentionally be other than stoichiometric, the solutions being described as acid, neutral, or acid deficient.

Comparison of Descaling Solutions for Aluminum Alloys (open access)

Comparison of Descaling Solutions for Aluminum Alloys

A laboratory test was performed to determine if a 10% oxalic acid solution could be safely be employed as a substitute to 2% chromic acid plus 5% phosphoric acid for removal of corrosion products from aluminum corrosion samples or slugs.

Investigation of Redox D-12 Waste Concentrator No. 2 Coil Nest Failure (open access)

Investigation of Redox D-12 Waste Concentrator No. 2 Coil Nest Failure

Four D-12 coil nests have failed since the start-up of the Redox Separations plant. Due to the high contamination and radiation levels of these vessels, the cost of decontamination has prevented the examination of all but one of the four. It was hoped that the examination of D-12 pot #2 would lead to an explanation of all four failures. This report will deal primarily with the metallurgical examination of the failure of D-12 pot #2.

Process Vessel Precision and Accuracy Estimates (open access)

Process Vessel Precision and Accuracy Estimates

The following is an attempt to explain the method by which the precision associated with an observed volume reading in a process vessel (E-12, C-1) should be calculated based upon a regression analysis of cumulative data. There are two types of volume measurement consists of estimating the total volume in a vessel at some inventory time. A transfer measurement consists of estimating the volume between two levels within a tank.

PRTR Single Tube Prototype Mockup (STPM) Operational Characteristics (open access)

PRTR Single Tube Prototype Mockup (STPM) Operational Characteristics

The Single Tube Prototype Mockup (STPM) was constructed to be used as a tool to evaluate the mechanical problems involved in operating and maintaining many components of the Plutonium Recycle Test Reactor (PRTR). This report has been written to acquaint interested HAPO components with the capability of the STPM and for use as an aid in scheduling tests and/or to properly evaluate testing results obtained from the mockup.

Rubber Ring Dosimeter Calibrations with the Plutonium Radiation Spectrum (open access)

Rubber Ring Dosimeter Calibrations with the Plutonium Radiation Spectrum

This work was initiated as an evaluation of the application pf rubber finger ring dosimeters to the control of extremity radiation exposure. The use of film dosimeters is a well known general practice throughout the radiation protection profession, however, film radiation exposure measurements associated with plutonium metal handling present a unique problem. The practical measurement of extremity dose depends upon the accuracy and reproducibility of results under the most severe conditions using a dosimeter of minimum size of the radiation exposure to the hands in the rubber finger ring.

A Simple Telephone Telemeter (open access)

A Simple Telephone Telemeter

When following the performance of automatic and semi-automatic equipment that is left unattended for extended periods of time, it is often desirable to be able to check this equipment by remote means. A convenient vehicle for such a check is the telephone since nearly all locations have or can have a telephone extension installed. The check of the equipment may be made as simple or extensive as desired, with the outcome of the check represented by a relay condition, for example. The condition of the relay is then transmitted to the interrogator over the telephone line by means of the presence or absence of a tone.
