A research and development program on the recovery and purification of potentially useful by-product actinides from the nuclear fuel cycle was carried out some years ago in the Federal Republic of Germany as part of the "Actinides Project" (PACT). In the course of this program, procedures for the recovery of neptunium, americium and curium isotopes from power reactor fuels, as well as procedures for the processing of irradiated targets of neptunium and americium to produce heat-source isotopes, have been developed. The history of the PACT Program has been reviewed previously (1). Most of the PACT activities were terminated towards the end of 1973, when it became evident that no major commercial market for the products in question was likely to develop.

This Symposium has been organized about new concepts, new systems, and new developments in actinide separations methodology. Much of the work reported here is based on fundamental actinide chemistry developed since the Manhattan Project days. The chapters in this volume describe ion exchange, solvent extraction, precipitation, pyrochemical, photochemical, and other methods of actinide separations as well as application of these separation methods to power reactor fuel reprocessing and recovery of actinides from waste solutions.

Electro-reduction and -oxidation processes are easy to operate and control remotely. Unlike the use of redox chemicals, they do not give rise to waste salts. Convenient remote control and operation and avoidance of waste salts are especially attractive features for commercial processing of any type of power reactor fuel. According]y, the electrode reactions were introduced quite early as intermediate steps in reprocessing. The electrochemical decladding of spent fuels was the first process in this field to be advanced up to the technical scale in the USA (J, 2 3, ...

The present paper reviews the processes which were designed by IHCH for the recovery of raw-material actinides from power reactor fuels and for the production of heat-source isotopes, and describes the state of development which has been reached.
