EVEREST · Experiments for Validation and Enhancement of the REactor preSsure vessel fluence assessmenT

The safety of a nuclear reactor relies heavily on modelling. In the last two decades, making use of the increased computer power available, advanced multi-physics solvers have been developed to reduce the level of conservatism when simulating pressurized water reactors. These tools rely on a first-principles based approach and produce solutions with a much finer spatial resolution. However they are seldom used in practice due to, amongst other things, the lack of dedicated experimental data for validation, especially when it comes to their improved spatial resolution.The EVEREST project intends to address this issue by quantifying the impact of using advanced MP models for the modelling of a VVER reactor (""usefulness"")
