Statis leaching of SIMFUEL in granite water at 200*C for 1, 10, 100, and 1000 hours under argon atmosphere and in presence of granite monoliths was studied. Three simulated burnup compositions (3, 6 and 8 at.%) were used. The results did not indicate any clear burnup effect.
These results were compared to results obtaineds from leaching tests on SIMFUEL and UO2 in demineralized water in air. Under these conditions, leach rates were significantly higher. With increasing leaching time, the surfaces became increasingly covered by crystals of redeposited uranium in an higher oxide form (e.g. schoepite).
