The section in which a particular activity is discussed is somewhat arbitrary at times. The complex web of collaborative international activities and organizations makes definitive assignment of activities to specific installations or nations very difficult or impossible.

The latter is a longer-term effort involving enhanced separation of all TRU elements, separation of long-lived fission products, and recycle of the TRUs and fission products to transmutation devices. This effort would involve new facilities.

provides an excellent, detailed overview of the OMEGA program. The Japanese program involves multiple organizations, including the Japan Atomic Energy Research Institute, the Power Reactor and Nuclear Fuel Development Corporation, and the Central Research Institute of Electric Power Industry.

Experimental and calculational study of actinide partitioning has been performed on cold and hot solutions based on the use of tributy} phosphate and di (2-ethyl hexyI) phosphoric acid extractants in what is designated the "CTH Process." Switzerland The Paul Scherrer Institute has conducted calculational studies related to actinide transmutation via spallation.

has increased from previous episodes of significant work on S&T. Relatively little work is evident on the fabrication aspects of feels with increased concentrations of minor actinides or long-lived fission products.
