Abstract

Abstract

This paper presents Part Parameters Separation（PPS） method. The method solves the APS problem effectively. To improve the practicability in using PPS method, the sensitivity affecting the radial power distribution is analyzed in this paper to determine the key parameters. On this basis, this paper establishes the radial power density distribution model, which is used in Fuel Rod Performance Analysis Code（FUPAC）. The model is validated with the measured data and the KYLIN-1 calculated results. The results show that the model has a high precision and a wide range of engineering practicality, and it is suitable for various types of fuels, such as UO₂ fuel, UO₂-Gd₂O₃ fuel and IFBA fuel.
