scrapers to remove refined uranium during a complete run. The electrical charge (measured in ampere hours) needed to electrorefine a kilogram of uranium is a measure of the refiner potential. Also, the HTER has been used to produce UCl3 needed for the Mark-V processing. Tests using the HTER and UCl3 production are on schedule to support the EMT demonstration.

James J. Laidler, ANL-E, described the EMT in light of other spent fuels DOE would need to process for disposition. Sodium-bonded fuels such as EBR-II, Fermi-I, and Fast Flux Test Facility fuels, can be treated directly. Oxide fuels would require reduction, such as that produced by lithium metal. Reduction rates are accelerated to useful rates using porous lithium cathodes that are produced in the reduction of lithium. Also, EMT had been identified as a backup approach to treating aluminum-clad fuels, although direct disposal and treating problem fuel in existing process canyons were identified as the preferred approaches. To process aluminum-clad fuel, EMT would first separate aluminum as a LLW after the addition of silicon to bind the uranium. Then uranium would be extracted. For aluminum-clad U3O8 fuel, the uranium oxide would have to be reduced before subjecting the fuel-salt mixture to EMT.

Dan Funk, representing the Office of Nuclear Energy, Science and Technology (NE) of the Department of Energy, discussed NE's interest that NE has in an objective evaluation of EMT for EBR-II fuel. The office would appreciate input from the committee on alternatives to EMT for EBR-II fuel and on the potential for applying EMT to some of DOE's other fuels. Mr. Funk described that the NE office will be developing an environmental impact statement for the treatment of spent fuel and has the responsibility to consider all reasonable alternatives.

The open discussion included clarification that some of the testing of waste forms will be under way but still incomplete at the end of the demonstration project. Also, Japan's and England's interest in EMT, as alternatives to aqueous processing, were discussed in light of the EMT demonstration project.

Executive Session

The committee met from 7:30 a.m. to 12:00 noon at conference facilities within the Shilo Inn, Idaho Falls, ID. The chairman followed the agenda as published above. The chairman issued research and writing assignments and scheduled two meetings of the committee, one for February 5 and 6, the other for March 16 and 17, 1978. Both meetings will be at the National Academy of Science facility in Washington, D.C. Following these meetings, the committee is expected to publish a report on its findings.
