Differential optical absorption techniques for diagnostics of coal gasification. Technical progress report, April-June 1983

Description: The application of differential optical absorption (DOA) techniques for the in-situ determination of the chemical composition of coal gasification process streams is investigated. Absorption spectra of relevant molecular species and the temperature and pressure effects on DOA-determined spectral characteristics of these species will be determined and cataloged. A system will be configured, assembled, and tested. 10 references, 1 figure.

Chromium in aqueous nitrate plutonium process streams: Corrosion of 316 stainless steel and chromium speciation

Description: According to the measurements made in this study, the only situation in which chromium (+6) could exist in a plutonium process solution is one in which a feed containing chromium is dissolved in a glass pot dissolver in high nitric acid concentration and at high temperature. But when the resulting feed is prepared for ion exchange, the chemical treatment reduces chromium to the +3 state. Any solution being processed through the evaporator will only contain chromium in the +3 state and any chrom… more

CHARACTERIZATION AND EVALUATION OF CAUSTIC WASH TANK AND SOLVENT HOLD TANK SAMPLES FROM MCU FROM AUGUST TO SEPTEMBER 2011

Description: During processing of Salt Batches 3 and 4 in the Modular Caustic-Side Solvent Extraction Unit (MCU), the decontamination efficiency for cesium declined from historical values and from expectations based on laboratory testing. This report documents efforts to analyze samples of solvent and process solutions from MCU in an attempt to understand the cause of the reduced performance and to recommend mitigations. CWT Solutions from MCU from the time period of variable decontamination factor (DF) per… more

Accidental nuclear excursion Recuplex operation 234-5 facility. Final report: Date of incident: April 7, 1962

Description: On Saturday morning, April 7, 1962, at about 1059 Armed Forces time, an accidental nuclear excursion occurred in the plutonium waste recovery facility (Recuplex) of the 234-5 Building. This excursion did not result in any mechanical damage or spread of contamination. Three employees of the General Electric Company received overexposures to gamma and neutron radiation. None were fatally exposed; in each case the overexposure was recognized promptly, and following medical observation and testing … 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

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

Chemical process safety at fuel cycle facilities

Description: This NUREG provides broad guidance on chemical safety issues relevant to fuel cycle facilities. It describes an approach acceptable to the NRC staff, with examples that are not exhaustive, for addressing chemical process safety in the safe storage, handling, and processing of licensed nuclear material. It expounds to license holders and applicants a general philosophy of the role of chemical process safety with respect to NRC-licensed materials; sets forth the basic information needed to proper… more

Supplemental Report: Technetium-99 On-Line Monitoring by Beta Counting for Hanford Supernate Waste Solutions

Description: SRTC is investigating approaches for near-real-time monitoring of 99Tc at selected points in the proposed pretreatment process for Hanford supernate waste solutions. The desired monitoring points include both the feed to and decontaminated product from a technetium-removal column. A Cs-removal column precedes technetium decontamination in the proposed process. Our earlier report (Ref. 1) showed that a simple flow-through beta counting system can easily meet 99Tc detection limit goals for soluti… more

Task 2.8 -- Mercury speciation and capture in scrubber solutions. Semi-annual report, July 1--December 31, 1996

Description: Investigations into mercury control across conventional scrubber systems have precipitated questions concerning (1) the initial speciation between oxidized and elemental forms of mercury in flue gas from coal-fired boilers and, subsequently, (2) the effects of scrubber slurry composition and pH on the mercury forms. Mercury capture in scrubber slurry is highly dependent on its form. Oxidized mercury is highly water-soluble and can be removed by scrubber slurry, whereas elemental mercury is not … more

Characterization of coal/waste coprocessing samples from HRI Run POC-2

Description: Coal and waste materials (plastics and rubber) were co-liquefied during Run POC-2 in HRI`s 3 T/D direct liquefaction process development unit under the DOE sponsored Proof-of-Concept program. Analytical characterizations were conducted of well-defined samples from representative periods of the run to provide information on the chemical transformation of these feedstocks and their distribution in product and recycle streams. The characteristics of the products and process streams were dependent … more
