title = "Development of a full-core reactivity equivalence for FeCrAl enhanced accident tolerant fuel in BWRs",
abstract = "The impact of replacing Zircaloy with a candidate iron-chromium-aluminum (FeCrAl) -enhanced accident-tolerant fuel (ATF) cladding material was evaluated for modern 10x10 boiling water reactor (BWR) fuel bundles. The primary objective was to establish fuel design parameters for FeCrAl that match the reactivity lifetime requirements of standard Zircaloy bundles. To compare the neutronic effects of these fuel alterations against standard U02/Zircaloy fuel, a method based on 2D lattice physics was established to estimate excess reactivity at the completion of each reactor operating cycle using a weighted fuel batch scheme. The methodology allows rapid scoping studies to be performed prior to full-core simulations. An additional paper [1] presents the lattice physics and 3D full-core results verifying the reactivity equivalence method for the alternate cladding fuel bundles.",
