摘要：

The European uility requirements (EUR) document states that the next generation European passive plant (EPP) reactor core design shall be optimized for UO2 fuel assemblies, with provisions made to allow for up to 50% mixed-oxide (MOX) fuel assemblies. The use of MOX in the core design will have significant impacts on key physics parameters and safety analysis assumptions. Furthermore, the MOX fuel rod design must also consider fuel performance criterion important to maintaining the integrity of the fuel rod over its intended lifetime. The purpose of this paper is to demonstrate that the AP1000 is capable of complying with the EUR requirement for MOX utilization without significant changes to the design of the plant. The analyses documented within will compare a 100% UO2 core design and a mixed MOX/UO2 core design, discussing relevant results related to reactivity management, power margin and fuel rod performance.
