Asphalt Emulsion Radon Barrier Systems for Uranium Mill Tailings: An Overview of the Technology

Description: Pacific Northwest Laboratory (PNL), under contract to the US Department of Energy (DOE) Uranium Mill Tailings Remedial Action Project (UMTRAP) office, has developed an asphalt emulsion cover system to reduce the release of radon from uranium mill tailings. The system has been field tested at Grand Junction, Colorado. Results from laboratory and field tests indicate that this system is effective in reducing radon release to near-background levels (<2.5 pCi m/sup -2/s/sup -1/) and has the propert… more

Development of low level liquid waste treatment systems: April-September 1981

Description: The pilot plant reverse osmosis system was demonstrated to be effective in removing large percentages of cobalt-60, iodine-125, and a mixture of cesium-137, cobalt-60, and iodine-125 from two types of aqueous streams. The effectiveness of three membrane porosities, 0, 50, and 97% salt rejection, were explored with each isotope. The 97% salt rejection membrane was the most effective in each experiment. Removals as high as 97.5% of the cobalt, 92.9% of the iodine and 95.1% of the combined isotope… more

Some chemical and mineralogical considerations important for understanding leachate chemistry

Description: Both the raw shale material and the retorting process parameters are influential in determining the subsequent behavior of the spent shale solids with respect to leaching and/or environmental weathering. The process parameters define the mineral reactions that occur to form the mineral assemblage in the spent shale, while the major and trace element residences and mobilities from the raw shale determine the extent of incorporation of these elements in the spent shale matrix and ultimately the c… more

Cyclone reburn using coal-water fuel: Pilot-scale development and testing

Description: There is an ongoing effort to develop retrofit technologies capable of converting oil- and/or gas-fired boilers to coal combustion. The objective of this project is to demonstrate the technical feasibility of an improved portion of a previously developed retrofit system designed for the purpose of converting oil/gas boilers. This improvement would almost entirely eliminate the use of premium fuels, thereby significantly increasing the economical attractiveness of the system. Specifically, the g… more

Feasibility of methods and systems for reducng LNG tanker fire hazards

Description: In this program concepts for reducing fire hazards that may result from LNG tanker collisions are identified and their technical feasibility evaluated. Concepts considered include modifications to the shipborne LNG containers so that in the event of a container rupture less of the contents would spill and/or the contents would spill at a reduced rate. Changes in the cargo itself, including making the LNG into a gel, solidifying it, converting it to methanol, and adding flame suppressants are al… more

Simple home-made sensors for potentiometric titrations. [Nitroform CH(NO/sub 2/)/sub 3/]

Description: A sensor for potentiometric titrations was prepared by coating a spectroscopic graphite rod with a solution of poly(vinyl chloride) and dioctyphthalate in tetrahydrofuran. The reference electrode was an Ag/AgCl single-junction electrode. The sensor was used in precipitation, acid-base, compleximetric, and redox titrations. Preparation of the coated-graphite sensor is simple and rapid. Moreover, it is quite inexpensive. A limitation is its applicability in aqueous media only, because organic sol… more

Methodology for the isolation and characterization of individual plutonium-bearing particles in atmospheric effluents from a nuclear processing plant

Description: A method for isolating and characterizing individual particles containing fissionable materials is described. Polycarbonate membrane filters are used to collect the particles from atmospheric effluents from a nuclear processing plant. Collected particles containing /sup 239/Pu or other fissionable materials are identified by fission fragment tracks produced by irradiating the polycarbonate film with thermal neutrons. Results show this method can be used to determine the size, /sup 239/Pu-conten… more

An HMS/TRAC analysis of a high-level radioactive waste tank

Description: It has been observed that a high-level radioactive waste tank generates quantities of hydrogen and nitrous oxide mixtures that are potentially well within flammability limits. These gases are produced from chemical and nuclear decay reactions in a slurry of radioactive waste material. The slurry is covered by a thick crust composed of sodium nitrate and nitrite salts. Significant amounts of the combustible and reactant gases are produced over a 3- to 4-month period before the crust ruptures and… more

Synergistic capture mechanisms for alkali and sulfur species from combustion

Description: An aerosol reactor system has been designed and constructed for the systematic study of the mechanisms governing the possible synergistic capture of sulfur oxide and alkalis with aluminosilicates and lime (CaO). Actual particle dynamics found in coal combustor systems can be simulated, mass balances can be closed, and the system conditions are well controlled. The collection of hot reactive aerosol flows is performed utilizing an isokinetic probe.

Conceptual design of a black liquor gasification pilot plant

Description: In July 1985, Champion International completed a study of kraft black liquor gasification and use of the product gases in a combined cycle cogeneration system based on gas turbines. That study indicated that gasification had high potential as an alternative to recovery boiler technology and offered many advantages. This paper describes the design of the plant, the construction of the pilot plant, and finally presents data from operation of the plant.

Separation of products from mild coal gasification processes

Description: The primary mild coal gasification product mixture containing noncondensible gas, high-boiling hydrocarbon vapors and entrained fines is difficult to process into the desired pure products: gas, liquids, and dry solids. This challenge for mild coal gasification process development has been studied by surveying the technical literature for suitable separations processes and for similar issues in related processes. The choice for a first-stage solids separation step is standard cyclones, arranged… more

Roasting and dissolution studies on nonirradiated thorium dioxide/uranium dioxide pellets

Description: Bench scale roasting and dissolution of ThO/sub 2/ and ThO/sub 2//UO/sub 2/ ractor-grade ceramic pellets were studied at the Savannah River Laboratory to define the key parameters affecting dissolution. Pellet breakup, and subsequent dissolution rates, were determined for ThO/sub 2/ and ThO/sub 2//UO/sub 2/ pellets roasted in air or in oxygen. Roasting ThO/sub 2//UO/sub 2/ pellets in air at temperatures from 400 to 900/sup 0/C caused the pellets to crack but not fragment. Roasting whole pellets… more

Inhibiting pitting corrosion in carbon steel exposed to dilute radioactive waste slurries

Description: Dilute caustic high-level radioactive waste slurries can induce pitting corrosion in carbon steel. Cyclic potentiodynamic polarization tests were conducted in simulated and actual waste solutions to determine minimum concentrations of sodium nitrate which inhibit pitting in ASTM A537 class 1 steel exposed to these solutions. Susceptibility to pitting was assessed through microscopic inspection of specimens and inspection of polarization scans. Long-term coupon immersion tests were conducted to … more
