Abstract

This work made a comprehensive analysis of the neutronic performance of annular dispersed particle fuel (ADF), and the results were compared with annular ceramic fuel (ACF), cylindrical dispersed particle fuel (CDF), and cylindrical ceramic fuel (CCF). The four types of cells are simulated by in-house code, and then the effective multiplication factor, neutron flux distribution, depletion characteristics, nuclides composition variation, and temperature coefficient of each fuel rod are compared and analyzed. Moreover, the characteristics of fuel assembly consisting of the four types of fuels are analyzed, including the effective multiplication factor, normalized pin power distribution, etc. The calculation results show that ADF has obvious advantages in all the indicators mentioned above. The calculation and analysis conducted in this paper could compare the advantages of the new annular dispersed particle fuel rod over the traditional fuel rod, which provides a certain reference for the application of the new fuel rod in engineering.
