摘要：
Nuclear fuel element is the key component of reactor, and its performance affects the safety and economy of reactor. It is of great significance for fuel design and safety analysis to carry out fuel element steady state irradiation performance predication using fuel performance analysis code. By developing fuel rod temperature, deformation, fission gas release and internal gas pressure calculation models, a high-performance parallel fuel performance analysis code Athena was built based on advanced parallel calculation method and thermal-mechanical multi-physical coupling scheme. The code was primarily verified by comparing the data of a typical commercial pressurized water reactor (PWR) nuclear power plant and the calculation results of similar code. The results show that Athena calculation results are reasonable and reliable. By defining the fuel power and thermal-hydraulic boundary conditions, the fuel performance analysis of the whole PWR core can be carried out to improve the efficiency. It is an important part of the numerical reactor prototype system (CVR1.0). © 2021, Editorial Board of Atomic Energy Science and Technology. All right reserved.
