Abstract

Abstract

In order to determine the accident tolerant fuel (ATF) element design schemes for future high performance pressurized water reactor (PWR), this study comprehensively analyzes several potential ATF design schemes from the perspectives of safety, economical efficiency and fuel performance by using the methods applicable to the analysis of fuel performance, nuclear design and reactor thermal safety. The results show that the scheme of using SiC composite cladding + high uranium density fuel is good. High uranium density fuel includes UN, U₃Si₂ and UN-U₃Si₂ composite fuels, each of them has distinct characteristics, Among them, UN-U₃Si₂ composite fuel can theoretically develop its strengths and avoid its weaknesses and become one of the characteristics of high uranium density fuel. However, from the perspective of neutron economy, it is necessary to enrich ¹⁵N in UN, and the current enrichment technology will greatly increase the manufacturing cost of this type of fuel. Therefore, the design scheme of SiC composite cladding + U₃Si₂ fuel should be selected for the design of ATF fuel element of high-performance PWR.
