Abstract

Abstract

For the reactor with closely arranged structure, it is particularly important to analyze the non-uniformity of circumferential temperature distribution of fuel rod cladding to prevent thermal stress failure of the cladding. In this paper, the theoretical analysis model is combined with the numerical fitting model, and the numerical fitting formula of the circumferential temperature distribution of the annular fuel rod in the lead-bismuth cooled tight cell is obtained under steady-state conditions, and compared with the numerical simulation data of computational fluid dynamics (CFD). The results show that the numerical fitting formula obtained in this paper has good accuracy, which can provide theoretical basis for the circumferential temperature analysis of fuel cladding of lead-bismuth reactor with annular fuel elements.
