Dried plutonium nitrate decontamination using HNO{sub 3} or Freon 113

Dried plutonium nitrate decontamination using HNO{sub 3} or Freon 113

Date: February 4, 1988
Creator: Holcomb, H. P.
Description: A request was made of the Separations Technology Laboratory to perform tests to determine the relative effectiveness of Freon 113 and 18% (3.15M) nitric acid on removing dried plutonium nitrate from Hypalon{reg_sign} gloves destined for use in F B-Line. Freon 113 was very inefficient for removing dried plutonium nitrate under conditions of moderate agitation of the liquid in contact with the dried compound. Nitric acid proved to be an excellent agent for decontaminating purposes for both the gloves and for the Pyrex glass. In tests conducted on the glass or on the gloves on which dried plutonium nitrate had not been removed by Freon 113, followup with nitric acid efficiently removed the residual plutonium nitrate. Tests were also conducted to give some measure of the resistance of the Hypalon glove to continuous contact with 18% HNO{sub 3} or with Freon 113. Following two weeks` immersion, there was little physical difference noted from the starting material, except the glove piece immersed in the Freon underwent an 8% weight gain.

Glovebox characterization and barrier integrity testing using fluorescent powder

Glovebox characterization and barrier integrity testing using fluorescent powder

Date: July 1, 1996
Creator: Wahlquist, D.R.
Description: This paper presents a method for characterizing the spread of contamination and testing the barrier integrity of a new glovebox during material transfer operations and glove change-outs using fluorescent powder. Argonne National Laboratory-West has performed this test on several new gloveboxes prior to putting them into service. The test is performed after the glovebox has been leak tested and all systems have been verified to be operational. The purpose of the test is to show that bag-in/bag-out operations and glove change-outs can be accomplished without spreading the actual contaminated material to non-contaminated areas. The characterization test also provides information as to where contamination might be expected to build-up during actual operations. The fluorescent powder is used because it is easily detectable using an ultra-violet light and disperses in a similar fashion to radioactive material. The characterization and barrier integrity test of a glovebox using fluorescent powder provides a visual method of determining areas of potential contamination accumulation and helps evaluate the ability to perform clean transfer operations and glove change-outs.

A new glove for glovebox workers

A new glove for glovebox workers

Date: October 1, 1996
Creator: Macdonald, J.M.; Nekimken, H.L.; Hermes, R.E.; Castro, J.M. & Evans, M.E.
Description: Lead-lined gloves used during the processing of nuclear materials within gloveboxes is an example of a barrier. To help prevent work contamination, current practice includes visual inspection and radiological monitoring of each glove on a regular basis. One administrative control requires radiological workers to monitor their hands upon removal form the glovebox gloves. In reality, either a catastrophic glove failure or the formation of pinholes can cause contamination which is detected after the fact. Real-time monitoring of glove integrity during use would help prevent the spread of contamination, minimize decontamination costs, and protect the glovebox worker. Another benefit of real-time monitoring is remotely alerting proper personnel of a glovebox glove breech. One of the most exciting aspects of this technology is the rapid detection of a breech in the glovebox glove. A puncture to a glove can be detected followed by an alert to a worker in less than a second. The benefits of a real-time monitoring system for glove integrity are immense. Examples of benefits using this new glove are: reducing work stoppage, personnel contamination, glovebox glove replacements, and the filing of costly reports. The primary application of this technology at Los Alamos National Laboratory would be protecting the ...

Sensitivity tests on leaded glove material, EMRTC Report FR-95-15: Final test report

Date: June 1, 1995
Creator: Olson, D.; Davis, L. & Block-Bolten, A.
Description: Small-scale safety and characterization tests were performed on stored radioactive wastes. The materials tested were formed when leaded dry box gloves were exposed to nitric acid. The nitration products exhibited thermal and impact sensitivity which could lead to ignition of explosion. Water was used to separate the nitrated glove material into several fractions; only the insoluble fraction exhibited significant sensitivity to impact. Both the separated and mixed materials were thermally unstable. Self-heating occurred at about 80C or lower, depending on the quantity of material tested. The drop weight impact sensitivity of one sample was greater than that of trinitrotoluene. The electrostatic spark discharge sensitivity of the nitration products was measured to be less than for typical secondary explosives. No sensitivity to friction was measured. These results indicate that the nitrated gloves can probably be handled without extreme risk of ignition. Washing the nitrated materials was found to desensitize the materials, indicating that water could be used as a solvent when storing the materials.

Remote mechanical operating methods vs rubber glove operating methods for the 234-5 process

Remote mechanical operating methods vs rubber glove operating methods for the 234-5 process

Date: September 23, 1952
Creator: Ingalls, W.P.
Description: The present RMA Line has now progressed through the run-in period and is engaged in actual production. Considerable new data and experiences are available for use in an evaluation of the basis used for design of the equipment in regard to contamination control and the safety of operating and maintenance personnel. Research and development funds have been allocated to the improvement of the 234-5 process equipment. Thus it is desirable that an up-to-date basis be established for use as criteria for the design development of these improvements. It is concluded that remote control operation of all plutonium purification and fabrication equipment is ultimately desirable. However, until reliable, tested, remote-control equipment is available, the remote control requirement may have to be compromised on some steps of the process to allow non-remote or rubber glove operation in order to obtain equipment with sufficient operating reliability.

Demonstration of the Tank Farm Washing Process and the DWPF SRAT Cycle with Sludge Batch 3 Simulant and Precipitated Pu/Gd Mixture from H-Canyon Tank 18.3

Date: September 23, 2002
Creator: Fellinger, T.L.
Description: The Nuclear Materials Management Division (NMMD) has proposed that certain Pu solutions stored in H-Canyon be disposed to H-Tank Farm. These solutions contain significant inventories of plutonium. The Pu/Gd mixture (along with the sludge slurry from Tank 7 and Am/Cm solution) will be processed as a part of Sludge Batch 3. Sludge Batch 3 is the next sludge batch of feed for the Defense Waste Processing Facility (DWPF). In order to prepare the feed for DWPF, the sludge slurry will be washed to approximately 0.55 M Na in the supernate. This report addresses the glove box work with a Sludge Batch 3 simulant and a Pu/Gd mixture precipitated from H-Canyon Tank 18.3. The main objective of this experimental work was to determine the behavior of the Pu and Gd during the Tank Farm washing process and the SRAT process.

Isotopic hydrogen analysis via conventional and surface-enhanced fiber optic Raman spectroscopy

Isotopic hydrogen analysis via conventional and surface-enhanced fiber optic Raman spectroscopy

Date: September 23, 2004
Creator: Lascola, Robert
Description: This report describes laboratory development and process plant applications of Raman spectroscopy for detection of hydrogen isotopes in the Tritium Facilities at the Savannah River Site (SRS), a U.S. Department of Energy complex. Raman spectroscopy provides a lower-cost, in situ alternative to mass spectrometry techniques currently employed at SRS. Using conventional Raman and fiber optics, we have measured, in the production facility glove boxes, process mixtures of protium and deuterium at various compositions and total pressures ranging from 1000-4000 torr, with detection limits ranging from 1-2 percent for as low as 3-second integration times. We are currently investigating fabrication techniques for SERS surfaces in order to measure trace (0.01-0.1 percent) amounts of one isotope in the presence of the other. These efforts have concentrated on surfaces containing palladium, which promotes hydrogen dissociation and forms metal hydride bonds, essentially providing a chemical enhancement mechanism.

Automated corrosion system in a moist environment

Automated corrosion system in a moist environment

Date: March 19, 1999
Creator: Hallman, R.L. Jr. & Calhoun, C.L.
Description: In an effort to assist researchers investigating the moisture-generated corrosion of metals and ceramics, a unique exposure system was developed. The initial goal of this system was to monitor corrosion ranging from a few monolayers at the outset of the corrosion process to high mass gains in more extensively corroded material. The new system uses a small robot arm for sample manipulation; gravimetric and Fourier transform infrared (FTIR) spectroscopy for corrosion-product determination; and a gas blending system to control the moisture content of the glove box in which the system is housed. The system's computer control can be configured to coordinate the examination of as many as 20 samples by periodic weighing and FTIR scanning. The computer also performs such functions as data logging of the temperature and pressure of the system and of the flow rate and moisture content of the purge gas. One main benefit of the computer-controlled robotic system is its ability to monitor samples 2 4 hours a day with precision control; this reduces problems stemming from human error or inconsistency of human technique.

Explosive Potential Analysis of AB Process-Final Report

Explosive Potential Analysis of AB Process-Final Report

Date: October 12, 2001
Creator: Bullock, J.S.; Giles, G.E. jr.; Wendel, M.W. & Sulfredge, C.D.
Description: A need arose to define the hazards associated with the operation of a process. The process involved the evolution of a hydrogen gas stream from thermal decomposition of uranium hydride at approximately 400 C into the interior of a purged argon-filled glove box. Specific hazards of interest included the potential reaction severity of the evolved hydrogen with atmospheric oxygen, either downstream in the vent system or inside the box in the event of serious air inleakage. Another hazard might be the energetic reaction of inleaked air with the hot uranium and uranium hydride powder bed, possibly resulting in the dispersion of powders into an air atmosphere and the rapid combustion of the powders. This was approached as a problem in calculational simulation. Given the parameters associated with the process and the properties of the glove box system, certain scenarios were defined and the potential for flammable or detonation reactions estimated. Calculation tools included a comprehensive fluid dynamics code, a spreadsheet, a curve-fitting program, an equation solver, and a thermochemistry software package. Results are reported which suggest that the process can be operated without significant hazard to operators or significant damage to equipment, assuming that operators take account of potential upset ...

Effect of Reducing Groundwater on the Retardation of Redox-Sensitive Radionuclides

Effect of Reducing Groundwater on the Retardation of Redox-Sensitive Radionuclides

Date: April 21, 2008
Creator: Hu, Q; Zavarin, M & Rose, T P
Description: Laboratory batch sorption experiments were used to investigate variations in the retardation behavior of redox-sensitive radionuclides. Water-rock compositions used during these experiments were designed to simulate subsurface conditions at the Nevada Test Site (NTS), where a suite of radionuclides were deposited as a result of underground nuclear testing. Experimental redox conditions were controlled by varying the oxygen content inside an enclosed glove box and by adding reductants into the testing solutions. Under atmospheric (oxidizing) conditions, the radionuclide distribution coefficients varied with the mineralogical composition of the sorbent and the water chemistry. Under reducing conditions, distribution coefficients showed marked increases for {sup 99}Tc and {sup 237}Np in devitrified tuff, but much smaller variations in alluvium, carbonate rock, and zeolitic tuff. This effect was particularly important for {sup 99}Tc, which tends to be mobile under oxidizing conditions. Unlike other redox-sensitive radionuclides, iodine sorption may decrease under reducing conditions when I{sup -} is the predominant species. Overall, sorption of U to alluvium, devitrified tuff, and zeolitic tuff under atmospheric conditions was less than in the glove-box tests. However, the mildly reducing conditions achieved here were not likely to result in substantial U(VI) reduction to U(IV). Sorption of Pu was not affected by the ...

High Efficiency Particulate Air (HEPA) Filter Generation, Characterization, and Disposal Experiences at the Oak Ridge National Laboratory

High Efficiency Particulate Air (HEPA) Filter Generation, Characterization, and Disposal Experiences at the Oak Ridge National Laboratory

Date: February 28, 2002
Creator: Coffey, D. E.
Description: High Efficiency Particulate Air filtration is an essential component of the containment and ventilation systems supporting the research and development activities at the Oak Ridge National Laboratory. High Efficiency Particulate Air filters range in size from 7.6cm (3 inch) by 10.2 cm (4 inch) cylindrical shape filters to filter array assemblies up to 2.1 m (7 feet) high by 1.5 m (5 feet) wide. Spent filters are grouped by contaminates trapped in the filter media and become one of the components in the respective waste stream. Waste minimization and pollution prevention efforts are applied for both radiological and non-radiological applications. Radiological applications include laboratory hoods, glove boxes, and hot cells. High Efficiency Particulate Air filters also are generated from intake or pre-filtering applications, decontamination activities, and asbestos abatement applications. The disposal avenues include sanitary/industrial waste, Resource Conservation and Recovery Act and Toxic Substance Control Act, regulated waste, solid low-level waste, contact handled transuranic, and remote handled transuranic waste. This paper discusses characterization and operational experiences associated with the disposal of the spent filters across multiple applications.

Improvement of the IRIS Process for Incineration of Various Radioactive Waste Compositions

Improvement of the IRIS Process for Incineration of Various Radioactive Waste Compositions

Date: February 26, 2003
Creator: Lemort, F. & Charvillat, J. P.
Description: Incineration represents a promising weight and volume reduction technique for alpha-contaminated organic waste. Following several years of laboratory research initiated in 1983 on a nonradioactive prototype unit at the CEA's Rhone Valley (Marcoule) Research Center, an innovative process, IRIS, has been developed to meet the need for processing nuclear glove box waste containing large amounts of chlorine. In March 1999, the first highly chlorinated alpha-contaminated waste was incinerated in the industrial facility based on the IRIS process at the CEA's Valduc Center. The nonradioactive prototype at Marcoule and the radioactive facility at Valduc demonstrated that the process is highly effective with a continuously fed rotating tubular kiln and with a very effective control of corrosion by pyrolytic decomposition of the waste initially at 550 C. The ash quality meets specification requirements (< 1% carbon, < 1% chlorine) and the volume and weight reduction factors are sufficient (around 30). The offgas treatment system exhibits very high operating efficiency complying with gaseous emission standards.

Oil, grease, and solvent removal from solid waste using supercritical carbon dioxide

Oil, grease, and solvent removal from solid waste using supercritical carbon dioxide

Date: August 1, 1995
Creator: Smith, H.M.; Olson, R.B.; Adkins, C.L.J. & Russick, E.M.
Description: Supercritical carbon dioxide extraction is being explored as a waste minimization technique for separating oils, greases, and solvents from solid waste. The contaminants are dissolved into the supercritical fluid and precipitated out upon depressurization. The carbon dioxide solvent can then be recycled for continued use. Definitions of the temperature, pressure, flowrate, and potential co-solvents are required to establish the optimum conditions for hazardous contaminant removal. Excellent extractive capability for common manufacturing oils, greases, and solvents has been observed in both supercritical and liquid carbon dioxide.
