• In this paper, we present the effect of nuclear data and its uncertainties on the core design of the KALIMER-600 Sodium Fast Reactor. The void reactivity coefficient, keff, and βeff are calculated with uncertainties due to the nuclear data of the main components of the reactor: 238U, 239,240Pu, 23Na, 56Fe, and 90Zr. Two methods are used: the “Total Monte Carlo” method involving many identical calculations with different sets of randomized nuclear data, and the perturbation method using MCNP. In a second step, the depletion is calculated together with radiotoxicity components after irradiation. By the Total Monte Carlo method, uncertainties due to nuclear data are propagated to the fuel composition and radiotoxicity curves.
