Fuel Management Strategy Analysis of Small Modular Pressurized Reactor ACP100

In order to achieve 24-months cycle length for Advanced Small Modular Pressurized Reactor (ACP100), and keep a balance between good fuel utilization and flat power distribution to assure reactor safety, using the well-developed software applied in engineering practice, this paper construct cases with combination of different number of assemblies per batch, enrichment types, and radial loading patterns; characteristics analysis of these cases could be referred during the confirmation of fuel management strategy of ACP100 reactor, and a recommended strategy is attained: combination of 3 batch loading and 24 assemblies per batch, along with partial low leakage loading pattern, and a higher enrichment to improve fuel economics.
