N2 - This paper documents the results of the analyses of local pin power peaking of the failed fuel assemblies, due to Pellet Clad Interaction (PCI), in Hatch Unit 1 Cycle 21. These analyses were performed with the latest CASMO5/SIMULATE5 codes utilizing the advanced neutronics and thermal hydraulic models, such as the Quarter Assembly Thermal Hydraulic (QTH) model, in an attempt to assess the impact of such detail models on the pin power peaking. CASMO5 and SIMULATE5 are Studsvik Scandpower's next generation lattice and nodal codes. The advanced features of CASMO5 and SIMULATE5 have shown to have a significant impact on the local peaking of assemblies in cells with skewed power and void profile.
