Simulation data demonstrating accuracy of a hybrid depletion framework. The method couples a high fidelity solution (Monte Carlo) at large "coarse step" intervals, with a faster reduced-order transport solution (deterministic or a perturbation-based prediction). This allows capturing reaction rates at a fine scale, without overly burdening the overall computational sequence. Data are arranged in two group: serpent and hybrid. The sub-groups in Serpent indicate the depletion scheme (ce or, leli) and depletion step size (5, 10, and 20). The hybrid group contains subgroups for 5, 10, and 20 day coarse steps, all with single day substeps. Reference solutions are in the "reference/serpent" and "reference/hybrid" groups. Inside each group, e.g. "serpent/ce/10", data for fluxes, isotopic compositions, and multiplication factor are contained.
