Optimization and parallelization of the thermal–hydraulic subchannel code CTF for high-fidelity multi-physics applications

•COBRA-TF was adopted by the Consortium for Advanced Simulation of LWRs.•We have improved code performance to support running large-scale LWR simulations.•Code optimization has led to reductions in execution time and memory usage.•An MPI parallelization has reduced full-core simulation time from day...
