Schematic design and safeguards instrumentation of a Gen IV fuel recycling facility.

• The sustainability criterion for Gen IV systems, inherently presumes the availability of efficient fuel recycling capabilities. Research activities concerning advanced fuel recycling are currently pursued, and one area for such research concerns safeguards aspects of recycling facilities. Since a recycling facility may be considered as sensitive from a non-proliferation perspective, it is important to address these issues early in the design process, according to the principle of Safeguards By Design.Presented in this paper is a suggested safeguards approach for a fuel recycling facility belonging to a small Gen IV lead-cooled fast reactor system that is under study in Sweden. A schematic design of a small-scale recycling facility, where actinides are separated using group actinide solvent extraction, is put forward. Measurement points are suggested based on available information on the recycling process activities and calculated material flows.Based on the identified need for measurements in the facility, possible techniques and instrumentation for measurements have been identified with the purpose to provide both inspecting parties and facility operators with necessary information for their respective needs. More generally, this type of analysis may be used to support Safeguards By Design in the planning of new recycling facilities.
