Abstract:

The structural materials of space nuclear reactors need to withstand extreme service environments such as high temperature and high-flux neutron irradiation, and their performance greatly affects the safety and economy of reactor operation. This paper focuses on the irradiation damage behavior of Mo-Re alloys used in space nuclear reactors, reviews irradiation damage effects, microstructure evolution caused by irradiation, and degradation of service performance. It provides a theoretical basis for the microstructure optimization, performance prediction, and service life evaluation of Mo-Re alloys as reactor materials.
