Abstract

Radial and axial fuel shuffling Traveling Wave Reactor (TWR)core were designed in detail, and burn-up calculation code MCORE was used to perform calculation and analysis. For the axial core, stable nuclide densities and power distribution were obtained, and the breeding-burning wave was simulated. For steady state, keff is 1.065, the drift speed is about 5.0 cm/a, and the burn-up is up to 400.0 MWD/kg-HM. For the 8 adial core, the fuel is shuffled from outside in, and the power distribution becomes stable after several shuffling steps. The results show that, asymptotic keff parabolically varies with the shuffling period, while the burn-up increases linearly with the shuffling period. To reduce the power peak, shuffling period 450 d is recognized as the best design. Asymptotic keff is 1.020, and the average burn-up is up to 156.0 MWD/kg-HM.
