Abstract:
The performance, including fuel rod corrosion, cladding growth and fuel assembly growth, of four group CF3 leading fuel assemblies in Qinshan-Ⅱ Nuclear Power Plant unit 2 from cycle 11 to cycle 13 are studied and compared to 1
st cycle irradiation of CF3 fuel assemblies. The results show that the irradiation performance of CF3 fuel assemblies are performing as expected and have more margin than the predicted value. The existing irradiation performance model can be used in the engineering design with further development.
