“…In Herman and Shwageraus (2011);Fridman et al (2013a); Hall et al (2013) the Serpent code was employed to produce 3D group constants for Resource-Renewable Boiling Water Reactor (RBWR) fuel assemblies having a strong axial heterogeneity. In Baier et al (2014) group constants for the 3D deterministic analysis of a block-type High Temperature Reactor were computed by Serpent.…”
