Description

For many years, Russian researchers have developed and tested a high density, high temperature U-Zr-C-N fuel for potential application in different types of reactors, including fast reactors. As part of this effort, reactor tests have been performed to low burnup. However, reactor-testing data is still needed at high burnup to confirm the optimal performance of the fuel. The SM-3 reactor, which is a high-flux reactor located in Dmitrovgrad, Russia, will be used to test a U-Zr-C-N (U0.9Zr0.1C0.5N0.5) fuel to ~40% burnup. The fuel will then be examined to determine its performance during irradiation. The fuel that will be tested has a density of 11.9 g/cm3 and an enrichment of 19.75% (uranium-235), and the uranium density of this fuel material is 10.8 g/cm3. About 1000 effective days of irradiation will be required to achieve the targeted burnup. This presentation will discuss the details of the planned irradiation, along with results of out-of-pile research that has been performed on the as-fabricated fuel. The positive characteristics of the U-Zr-C-N fuel will be discussed, and comparisons will be made to other fuel types.
