A -- STIRRED GLASS MELTER POC Terry Montgomery, Telephone 1-803-725-7789 E-MAIL: click here to contact Terry Montgomery via e-mail, terry.montgomery@srs.gov. The U.S. Department of Energy (DOE) is seeking Expressions of Interest regarding the application of a prototype stirred glass melter and power supply owned by the DOE and stored at its Savannah River (SR) facilities near Aiken, South Carolina. The stirred melter and power supply is a unitized platform design complete with control panels and is adaptable to highway transport. The melter was purchased by the DOE in 1993 for approximately $2.9M as a potential alternative melter technology for use at the Defense Waste Processing Facility (DWPF). Testing proved the original DWPF melter capable of supporting the High Level Waste (HLW) vitrification mission and the DOE eliminated testing and development of the stirred glass melter. The stirred melter has not been operated. No other end use is currently identified for the stirred melter. Therefore, the DOE is considering offering this melter to a commercial or research institution. The melter may potentially be developed for application to hazardous or low level waste vitrification or other alternative use. The stirred melter was designed for a production capacity of 228 lb/hr of glass based on a simulated HLW slurry consisting of 60% water and 40% solids. The tank material of construction is Inconel 690 with an internal configuration of 36"x36"x60". The melter tank has removable water cooled exterior panels. The power supply is 350 KVA, single phase power supply, NEMA 12, water cooled, with dual voltage ranges of 150 volts or 300 volts. The stirred melter was built for testing and is not designed for remote processing of HLW. Remote operation and maintenance features have not been incorporated into the design. Therefore, its application would appear to be best suited for hazardous or low level waste vitrification where hands-on maintenance is possible. A small scale stirred melter is located at the Clemson University Vitrification Research Laboratory (Clemson, South Carolina) and could be made available for testing. The Savannah River Technology Center has recognized expertise in vitrification technology, and collaborative research and development is possible. Consideration for providing the stirred melter to a company or research institution will be based on the proposed end use, experience and capability of the entity in the proposed field of application, and financial resources capable of supporting its application and/or testing. The DOE will not consider financial support for either its application or testing but will consider bearing the cost of transportation and incidentals necessary to safely deliver the stirred melter if it is offered. Contractual agreements may be necessary to protect any proprietary or trade secrets information associated with the melter design and its support equipment. It is anticipated that the names and addresses of respondents to this Request for Expressions of Interest will comprise the source list for any Request for Proposals that the DOE may prepare. Please be advised that this source list will be provided to interested parties on request. Interested parties should provide Expressions of Interest and comments along with a brief synopsis of intended use, organization capabilities, and a contact person to Terry Montgomery, U.S. Department of Energy, Savannah River Operations Office, Building 703-46A, P.O. Box A, Aiken, SC 29802. Expressions of Interest will also be accepted via electronic mail at terry.montgomery@srs.gov. Questions are to be in writing to the same contact. All expressions should be provided in writing via regular or electronic mail no later than August 18, 1997. This is not a solicitation for a formal contract but is an announcement of opportunity only. (0199)
