Abstract This Plan demonstrates the availability of technologies for processing TRISO used nuclear fuel for waste management and actinide recovery purposes. These technologies are judged to be at a very low level of technology readiness and as such they constitute a fertile research area for the DOE-NE’s Office of Materials and Chemical Technologies. Strategies to mature the technologies to a point where they can reasonably be considered in engineering alternatives analyses typically involve laboratory-scale tests using fuel simulant to characterize process streams and demonstrate key engineering features. Several criteria are available to help selecting candidate technologies for further maturation. also applicable to processing unirradiated TRISO fuel to recover High Assay Low Enriched Uranium, for example, from fresh fuel that has failed quality requirements. appropriate material, forms and fabrication techniques. Laboratory-scale studies can be performed with simulants and unirradiated fuel and then verified with irradiated fuel. A source of irradiated fuel to be identified but fuel may not have to be irradiated in a reactor to induce the key irradiation effects For large scale tests of a technology’s simulants used understanding laboratory-scale.
