Summary of current state-of-the-art and next development steps for the fuel systems studied in this paper.
| Fuel system | Uranium loading | Current status (LEU-FOREvER) | Next steps in EU QUALIFY |
|---|---|---|---|
| U3Si2(standard) fuel | 4.8gU/cc | Readily used in research reactors | Verification in mixed elements with thick meat at high power (ME-CHARTREUSE) |
| U3Si2 HD fuel | 5.3–5.6gU/cc | Four (4) full-scale plates successfully tested in relevant irradiationconditions | Verification in mixed elements experiments with 5.3gU/cc (ME-DEUS) |
| UMo dispersion fuel | ∼8 gU/cc | One (1) full-scale plate successfully tested in relevant irradiationconditions | Verification with four (4) full-scale plates (EF3 experiment) |
| UMo monolithic fuel | ∼16 gU/cc | Mini-plates successfully irradiationtested | Verification in full-scale plates (FM1 experiment) |
