Composite electrodes for advanced electrochemical applications. Quarterly report for the period July 1 - September 30, 1999

Description: The electrochemical industry is one of the most highly energy-intensive industries today. However, there have been no significant advances in the electrodes that these industries use. The dimensionally stable anode (DSA), which ELTECH introduced under a license agreement, has been the industry standard for the past twenty-five years. But, DSAs are nearing the end of their technological prevalence. The principal problems with DSAs include high capital and operating cost, and the proprietary natu… more

Fate of soluble uranium in the I{sub 2}/KI leaching process for mercury removal

Description: General Electric Corporation has developed an extraction and recovery system for mercury, based upon the use of iodine (oxidant) and iodide ion (complexing agent). This system has been proposed for application to select mercury-contaminated mixed waste (i.e., waste containing radionuclides as well as other hazardous constituents), which have been generated by historic activities in support of US Department of Energy (DOE) missions. This system is compared to a system utilizing hypochlorite and … more

Test procedure for anion exchange testing with Argonne 10-L solutions

Description: Four anion exchange resins will be tested to confirm that they will sorb and release plutonium from/to the appropriate solutions in the presence of other cations. Certain cations need to be removed from the test solutions to minimize adverse behavior in other processing equipment. The ion exchange resins will be tested using old laboratory solutions from Argonne National Laboratory; results will be compared to results from other similar processes for application to all plutonium solutions store… more

Chloride content of Rocky Flats scrub alloy twelfth campaign solution following head end treatment

Description: A single batch of dissolver solution from the twelfth Rocky Flats Scrub Alloy (RFSA) campaign has been analyzed for chloride content following head end treatment to reduce its concentration. Scrub alloy buttons were dissolved in Tank 6.4D during July. In subsequent head end processing, chloride was precipitated with mercurous ion added as the nitrate. The precipitate, Hg{sub 2}Cl{sub 2}, was co-removed with the gelatin floc via centrifugation. Duplicate samples from Tank 11.2, containing the he… more

Solids formation on filtrate neutralization

Description: The Separations Technology Laboratory was requested to study what happens when a filtrate solution, which will be a F B-Line product, is neutralized with sodium hydroxide. The primary concern was the formation of solids that could cause damage in pump seals, resulting in their failure. The results of these experiments indicate that under process conditions, granular, crystalline sodium fluoride will be produced by rapid neutralization of the filtrate solution with 50% NaOH plus a 25 volume perc… more

Chloride content of dissolver solution from Rocky Flats alloy thirteenth campaign following head end treatment

Description: F-Canyon continues to obtain good chloride removal from Rocky Flats Alloy solution during head end treatment. One single batch of solution from the thirteenth alloy campaign, dissolved earlier this month, has been successfully processed. This was the first campaign to combine Rocky Flats Scrub Alloy (RFSA) with Rocky Flats Anode Heel Alloy (RFAHA) in the same dissolution solution (TA-2-1183). Following dissolution in Tank 6.4D, chloride was precipitated with mercurous ion added as the nitrate. … more

Caustic Precipitation of Plutonium and Uranium with Gadolinium as a Neutron Poison

Description: The caustic precipitation of plutonium (Pu) and uranium (U) from Pu and U-containing waste solutions has been investigated to determine whether gadolinium (Gd) could be used as a neutron poison for precipitation with greater than a fissile mass containing both Pu and enriched U. Precipitation experiments were performed using both process solution samples and simulant solutions with a range of 2.6-5.16 g/L U and 0-4.3:1 U:Pu. Analyses were performed on solutions at intermediate pH to determine t… more

PFP solution stabilization

Description: This Functional Design Criteria (FDC) addresses remediation of the plutonium-bearing solutions currently in inventory at the Plutonium Finishing Plant (PFP). The recommendation from the Environmental Impact Statement (EIS) is that the solutions be treated thermally and stabilized as a solid for long term storage. For solutions which are not discardable, the baseline plan is to utilize a denitration process to stabilize the solutions prior to packaging for storage.

Solution monitoring: Quantitative benefits to safeguards

Description: This paper investigates how SM (essentially continuous monitoring of solution level, density, and temperature in all key process tanks) can improve loss detection in a formal statistical sense. The authors use a simulation code developed at Los Alamos (FACSIM) to simulate data from the Rokkasho Reprocessing Plant (RRP), which is now under construction in Japan. They show the possibility of reducing the effect of systematic errors by using solution monitoring data to calculate bias corrections. … more

Simultaneous measurements of plutonium and uranium in spent-fuel dissolver solutions

Description: The authors have studied the isotope dilution gamma-ray spectrometry (IDGS) technique for simultaneous measurements of elemental concentrations and isotopic compositions for both plutonium and uranium in input spent-fuel dissolver solutions at a reprocessing plant. The technique under development includes both sample preparation and analysis methods. For simultaneous measurements of both plutonium and uranium, a critical issue is to develop a new method to keep both plutonium and uranium in the… more

A method and apparatus for sizing and separating warp yarns

Description: A slashing process for preparing warp yarns for weaving operations includes the steps of sizing and/or desizing the yarns in an acoustic resonance box and separating the yarns with a leasing apparatus comprised of a set of acoustically agitated lease rods. The sizing step includes immersing the yarns in a size solution contained in an acoustic resonance box. Acoustic transducers are positioned against the exterior of the box for generating an acoustic pressure field within the size solution. Ul… more

Equilibrium characteristics of tartrate and EDTA-based electroless copper deposition baths

Description: Electroless deposition of copper is being used for a variety of applications, one of them being the development of seed metallic layers on non-metals, which are widely used in electronic circuitry. Solution equilibrium characteristics of two electroless copper baths containing EDTA and tartrate as the complexing agents were studied as functions of pH, chelating agent and metal ion concentrations. Equilibrium diagrams were constructed for both cu-tartrate and Cu-EDTA systems. It was determined t… more

Analysis of Americium in Transplutonium Process Solutions

Description: One of the more difficult analyses in the transplutonium field is the determination of americium at trace levels in a complex matrix such as a process dissolver solution. Because of these conditions a highly selective separation must precede the measurement of americium. The separation technique should be mechanically simple to permit remote operation with master-slave manipulators. For subsequent americium measurement by the mass spectroscopic isotopic-dilution technique, plutonium and curium … more
