Sažetak
The International Reactor Innovative and Secure (IRIS), an integral, modular, medium size (335 MWe) PWR, has been under development since the turn of the century by an international consortium led by Westinghouse and including over 20 organizations from nine countries[1]. Maintenance of IRIS reactor has been optimized to enable extended operating cycles up to four years[2]. Different IRIS reactor fuel management options have been examined with the assumption of current enrichment licensing limitation (less than 5% enriched uranium oxide) [3]. To fully exploit the IRIS optimized maintenance, and at the same time improve fuel utilization, a core design enabling a 4 year cycle together with a three-batch reloading scheme is desirable. However, this requires not only the increased allowed burnup but also use of fuel with enriched uranium oxide beyond 5%. This paper considers three-batch reloading scheme for 4 year operating cycle with the assumptions of increased discharge burnup and fuel enrichment beyond 5%. Preliminary studies have been performed resulting in development of three-batch core design. It must be emphasized that this study is completely outside the current licensing efforts, but it is of long-term interest for potential future IRIS design upgrades.
