Zusammenfassung:The operating time of the IBR-2 reactor depends on the fuel life. Currently, an IBR-2 run is formed at the cost of adding fresh FAs into the core without any reshuffling of the FA. In spite of its technological simplicity, this approach results in suboptimal fuel use because of high burnup non-uniformity. In the present work we propose optimizing a reactor fuel run by reshuffling FA during the run. This will give more uniform fuel burnup and increase the run time by almost 1/4 while limiting the ultimate burnup as compared with the conventional approach to run formation without reshuffling.
