Study on the Different Dynamic Models and its Simplified Standards of the PWR Neutron

Abstract:

According to the world average generation levels, the nuclear power generation is the third-largest energy generation form following the thermal and hydroelectric ones. Among all the operating nuclear generation, the type of the PWR has occupied more than 50%. The paper constructed three most commonly used dynamic PWR neutron models, which are six-groups delayed, single-group delayed and linearized neutron model, and made a detail analysis of those different models. An investigation of the different errors among the models under different perturbations is taken by simulation and a standard for the simplification of the models had been proposed, which can provide a reference for the selection of the future PWR neutron dynamic model.
