Design features of the radioactive Liquid-Fed Ceramic Melter system

Description: During 1983, the Pacific Northwest Laboratory (PNL), at the request of the Department of Energy (DOE), undertook a program with the principal objective of testing the Liquid-Fed Ceramic Melter (LFCM) process in actual radioactive operations. This activity, termed the Radioactive LFCM (RLFCM) Operations is being conducted in existing shielded hot-cell facilities in B-Cell of the 324 Building, 300 Area, located at Hanford, Washington. This report summarizes the design features of the RLFCM system… more

Design requirement for dual air supplies to melter borescope

Description: The long term survivability and usefulness of the melter surface viewing borescopes would be greatly increased if a method of remote lense cleaning was available. The two units to be installed on the DWPF melter will incorporate air cooling and lense purging into their design. At present a single air supply line would serve both needs. Separating the two air services will allow the introduction of water or steam into the purge service. Tests on the prototype borescope at ETF have shown this to … more

Energy and materials flows in the iron and steel industry

Description: Past energy-consumption trends and future energy-conservation opportunities are investigated for the nation's iron and steel industry. It is estimated that, in 1980, the industry directly consumed approximately 2.46 x 10/sup 15/ Btu of energy (roughly 3% of total US energy consumption) to produce 111 million tons of raw steel and to ship 84 million tons of steel products. Direct plus indirect consumption is estimated to be about 3.1 x 10/sup 15/ Btu. Of the set of conservation technologies iden… more

Off-gas characteristics of liquid-fed joule-heated ceramic melters

Description: The off-gas characteristics of liquid-fed joule-heated ceramic melters have been investigated as a function of melter operational condition and simulated waste feed composition. The results of these studies have established the identity and behavior patterns of gaseous emissions, the characteristics of melter-generated aerosols, the nature and magnitude of melter effluent losses and the factors affecting melter operational performance. 8 figures, 16 tables.

LFCM (liquid-fed ceramic melter) processing characteristics of mercury

Description: An experimental-scale liquid-fed ceramic melter was used in a series of tests to evaluate the processing characteristics of mercury in simulated defense waste under various melter operating conditions. This solidification technology had no detectable capacity for incorporating mercury into its borosilicate, vitreous, product, and essentially all the mercury fed to the melter was lost to the off-gas system as gaseous effluent. An ejector venturi scrubber condensed and collected 97% of the mercur… more

Thermal design and analysis of the HTGR fuel element vertical carbonizing and annealing furnace

Description: Computer analyses of the thermal design for the proposed HTGR fuel element vertical carbonizing and annealing furnace were performed to verify its capability and to determine the required power input and distribution. Although the furnace is designed for continuous operation, steady-state temperature distributions were obtained by assuming internal heat generation in the fuel elements to simulate their mass movement. The furnace thermal design, the analysis methods, and the results are discusse… more

Improving feed slurry rheology by colloidal techniques

Description: Pacific Northwest Laboratory (PSN) has investigated three colloidal techniques in the laboratory to improve the sedimentation and flowability of Hanford simulated (nonradioactive) current acid waste (CAW) melter feed slurry: polymer-induced bridging flocculation; manipulating glass former (raw SiO/sub 2/ or frit) particle size; and alteration of nitric acid content. All three methods proved successful in improving the rheology of the simulated CAW feed. This initially had exhibited nearly worst… more

Connecting section and associated systems concept for the spray calciner/in-can melter process

Description: For a number of years, researchers at the Pacific Northwest Laboratory have been developing processes and equipment for converting high-level liquid wastes to solid forms. One of these processes is the Spray Calciner/In-Can Melter system. To immobilize high-level liquid wastes, this system must be operated remotely, and the calcine must be reliably conveyed from the calciner to the melting furnace. A concept for such a remote conveyance system was developed at the Pacific Northwest Laboratory, … more

LFCM (liquid-fed ceramic melter) vitrification technology: Quarterly progress report, July-September 1986

Description: Individual papers are processed separately for the data bases. This report documents progress on liquid-fed ceramic melter (LFCM) vitrification technology. Progress in melting process chemistry and glass development, feed preparation and transfer systems, melter systems, off-gas systems, and process/product modeling and control is discussed.
