Assessment of selected furnace technologies for RWMC waste

Description: This report provides a description and initial evaluation of five selected thermal treatment (furnace) technologies, in support of earlier thermal technologies scoping work for application to the Idaho National Engineering Laboratory Radioactive Waste Management Complex (RWMC) buried wastes. The cyclone furnace, molten salt processor, microwave melter, ausmelt (fuel fired lance) furnace, and molten metal processor technologies are evaluated. A system description and brief development history ar… more

Performance of a large-scale melter off-gas system utilizing simulated SRP DWPF waste

Description: The Department of Energy and the DuPont Company have begun construction of a Defense Waste Processing Facility to immobilize radioactive waste now stored as liquids at the Department of Energy's Savannah River Plant. The immobilization process solidifies waste sludge by vitrification into a leach-resistant borosilicate glass. Development of the process has been the responsibility of the Savannah River Laboratory. As part of the development, two large-scale glass melter systems have been de… more

Glass melter off-gas system pluggages: Cause, significance, and remediation

Description: Liquid high-level nuclear waste will be immobilized at the Savannah River Site (SRS) by vitrification in borosilicate glass. The glass will be produced in the Defense Waste Processing Facility (DWPF) where the glass will be poured into stainless steel canisters for eventual disposal in a geologic repository. Experimental glass melters used to develop the vitrification process for immobilization of the waste have experienced problems with pluggage of the off-gas line with solid deposits. Off-gas… more

Design and operating features of the high-level waste vitrification system for the West Valley demonstration project

Description: A liquid-fed joule-heated ceramic melter system is the reference process for immobilization of the high-level liquid waste in the US and several foreign countries. This system has been under development for over ten years at Pacific Northwest Laboratory and other national laboratories operated for the US Department of Energy. Pacific Northwest Laboratory contributed to this research through its Nuclear Waste Treatment Program and used applicable data to design and test melters and related syste… more

Design of a mixing system for simulated high-level nuclear waste melter feed slurries

Description: The Nuclear Waste Treatment Program development program consists of coordinated nonradioactive and radioactive testing combined with numerical modeling of the process to provide a complete basis for design and operation of a vitrification facility. The radioactive demonstration tests of equipment and processes are conducted before incorporation in radioactive pilot-scale melter systems for final demonstration. The mixing system evaluation described in this report was conducted as part of the no… more

Vitrification of high-level radioactive waste in a pilot-scale liquid-fed ceramic melter

Description: Under the sponsorship of the Nuclear Waste Treatment Program (NWTP), a high-level radioactive waste vitrification system has been installed in a Radiochemical Engineering Facility at Hanford, Washington. The facility is designed for remote operation of equipment using master-slave manipulators and overhead cranes. The pilot-scale radioactive system consists of a melter, canister handling turntable, glass-level detection system and supporting waste preparation, offgas treatment and condensate tr… more

State-of-the-Art in Residential and Small Commercial Air Handler Performance

Description: Although furnaces, air conditioners, and heat pumps have become significantly more efficient over the last couple of decades, residential air handlers have typical efficiencies of only 10% to 15% due to poor electric motor and aerodynamic performance. These low efficiencies indicate that there is significant room for improvement of air handler fans. The other 85-90% of the electricity used by air handlers is manifested as heat. This extra heat reduces air conditioning cooling and dehumidificati… more

Criteria determining the selection of slags for the melt decontamination of radioactively contaminated stainless steel by electroslag remelting

Description: Electroslag remelting is an excellent process choice for the melt decontamination of radioactively contaminated metals. ESR furnaces are easily enclosed and do not make use of refractories which could complicate thermochemical interactions between molten metal and slag. A variety of cleaning mechanisms are active during melting; radionuclides may be partitioned to the slag by means of thermochemical reaction, electrochemical reaction, or mechanical entrapment. At the completion of melting, the … more
