Following briefings from a number of individuals in the nuclear energy field concerning different aspects of the electrometallurgical process, the committee made the following two statements: · The committee concluded that electrometallurgical techniques represent a sufficiently promising technology for treating a variety of DOE spent fuels to warrant continued R&D in federal FY96. · During the next 12 months the DOE should closely follow the progress of the proposed R&D program to determine whether it should be continued beyond FY96.

· A decision on the use of the electrometallurgical technique for weapons plutonium disposition cannot be made until the demonstration of this technology shows whether or not this process is viable for treating DOE spent fuels. If a weapons plutonium disposition technology is to be selected for use with weapons pits before the electrometallurgical technology demonstration program is concluded, this committee recommends that the electrometallurgical technique not be included as a candidate technology.

step in guiding ANL' s future testing program. · The committee recommends that upon satisfactory completion of the demonstration with EBR-II fuel, the electrometallurgical technique should be evaluated in the broader context of alternative technologies for processing spent nuclear fuel.

The committee examined electrometallurgical technology in light of other possible treatment technologies for spent nuclear fuel, and it evaluated the success criteria developed by ANL and DOE for the demonstration project: · Confirmation that the waste forms produced by EMT are acceptable within the DOE's Office of Radioactive Waste (DOE-RW) Office of Civilian Radioactive Waste Management (OCRWM)

· The committee believes that characterization of the ceramic waste form should be accelerated in order to determine the mechanism of transformation of salt-loaded zeolite 4A to sodalite. Electrometallurgical Techniques for DOE Spent Fuel Treatment: An Assessment of Waste Form Development and Characterization (Report 9, l999J In conversations between personnel of DOE and the NRC, it was agreed that the committee would produce a report that would examine the issue of waste form testing and development as it related to ANL's demonstration project.

Finding: ANL' s tests over the several months duration of the test indicate that the CWF dissolves at a rate equal to or less than reference defense high level waste borosilicate glass. Conclusion: If there is no change in long-term release mechanism under simulated repository conditions, the release performance of CWF (dissolution rate)

Conclusion: These continuing concerns are not expected to jeopardize the timely completion of the EBR-II demonstration project in 1999, but attention should be devoted to their resolution prior to extending the EMT process past the demonstration. Conclusion: Alternative, conservatively bounding strategies for assuring safe disposal of such relatively small quantities of novel HEW may result in significant cost avoidance while still protecting public safety.
