Different countries choose different type of fuel for future fast reactors. In addition to oxide fuels, there are metal fuels, nitride fuels, and carbide fuels as the alternatives. Metal fuel was the choice of the first generation of fast reactors in the world; Nitride fuels and carbide fuels are ideal fast reactor fuel candidates due to their high metal atomic density, high thermal conductivity, and high melting point. The technical maturity of these fuels is temporarily low. In order to comprehensively compare the development prospects of various types of fuels in reactors for different purposes, it is necessary to understand its basic properties and the characteristics of the application on the reactors. This paper investigates the development history and application status of three types of fuels. For the same reactor core, the advantages and disadvantages of the fuels in terms of fuel loading, reactivity coefficient, safety margin and economy are analyzed and compared by the neutronic code calculation. Based on the conclusions of this paper, technicians can choose the appropriate type of fuel according to different core types when designing new fast reactors in the future, so as to give full play to the specific advantages of each type of fuel.
