A description is given of a model for evaluation of core heat-up transients and the performance of emergency core spray cooling systems for light-water reactors. The model is based on a detailed analysis of the energy generation including metal-water reactions, heat conduction, forced convection, boiling heat transfer, thermal radiation, and the two-phase flow based on thermal non-equilibrium in the core and the primary system. The applicability of the model is demonstrated by comparison with the BWR-FLECHT experiments and a BWR/6 calculation.
