In this work, high-fidelity calculations using a recently developed coupled scheme between the Serpent 2 Monte Carlo transport code and the SUBCHANFLOW subchannnel thermal–hydraulic code are done for the well-known full core MOX/UO2 PWR OECD/NRC benchmark. Main steps proposed within the benchmark are developed, ranging from uncoupled 2D cases to full 3D coupled cases both for steady-state and transient scenarios. A good agreement is found with the reported values, assessing the capabilities of this novel approach to provide highly-detailed results at a full-core PWR level using a pin-by-pin coupling.
