A comparative study of bifurcation characteristics in single and two-zone fuel models of a BWR: A case study of the advanced heavy water reactor (AHWR)

•A simplified model with refined radial fuel heat transfer modeling is studied.•Method of multiple scales for nonlinear analysis and oscillation characteristics.•Refinement in radial fuel heat transfer improves the overall system stability. A simplified nuclear-coupled thermal–hydraulic model follow...
