Work on this project is focused on developing design and licensing information for the model facility. Final deliverables were prepared this period to submit to DOE for the licensing and high-density rack sub-tasks. DOE revised and reduced the scope of the 1981 AFR contract in June of 1981. Work is progressing satisfactorily to close out the remaining tasks under the revised scope by September 30, 1981.

ATA is a pulsed, 50 ns 10 KA, 50 MeV linear induction electron accelerator at LLNL. The ETA could be used as an injector for ATA. However the possibility of building a new injector gun for ATA, raised the question as to what changes from the ETA gun in electrode dimensions or potentials, if any, should be considered. In this report the EBQ code results for the four electrode configurations are reviewed and an attempt is made to determine the geometrical scaling laws appropriate to these ETA type gun geometries. Comparison of these scaling laws will be made to ETA operation. The characteristic operating curves for these geometries will also be presented and the effect of washer position determined. It will be shown that emittance growth will impose a limitation on beam current for a given anode potential before the virtual cathode limit is reached.

Work on this project is focused on demonstrating disassembly and encapsulation of nuclear fuels as a means to increase spent fuel storage. The effort commenced on April 17, 1980, and is progressing satisfactorily. The Equipment/Procedure Preparation sub-task is essentially complete. The Equipment Demonstration sub-task and the Process Assessment Studies sub-task continue. The equipment design effort associated with the first sub-task, the component testing and checking associated with the second sub-task, and the technical studies and investigations associated with the latter sub-task continue to verify the feasibility of this concept to enhance the use of fuel storage resources.
