N2 - In the framework of the EU Horizon 2020 McSAFE project, high-fidelity multiphysics capabilities are being developed to carry out large-scale burnup calculations for Light Water Reactors. As part of this effort, the Serpent 2 Monte Carlo code has been coupled to thermalhydraulics and fuel-performance codes, with the final objective of performing fully coupled full-core pin-by-pin simulations. To enable memory scalability, needed for these massive problems, a Collision-based Domain Decomposition (CDD) scheme has been implemented in Serpent 2. The methodology is based on data decomposition for burnable materials and a domain decomposition particle-tracking algorithm, and is shown here to provide the required memory scalability and computational performance, with up to 50% speedup efficiency at 5,120 cores. The application of the CDD feature is demonstrated in a pin-by-pin depletion calculation for a Pre-Konvoi PWR reactor.
