The small modular liquid-metal fast reactor (SMFR) is an important component of advanced nuclearsystems. SMFRs exhibit relatively low breeding capability and constraint space for control rod installation. Consequently, control rods are deeply inserted at beginning and are withdrawn gradually tocompensate for large burnup reactivity loss in a long lifetime. This paper is committed to investigatingthe impact of control rod compensation operation on core neutronics characteristics. This paper presentsa whole core fine depletion model of long lifetime SMFR using OpenMC and the influence of depletionchains is verified. Three control rod position schemes to simulate the compensation process arecompared. The results show that the fine simulation of the control rod compensation process impactssignificantly the fuel burnup distribution and absorber consumption. A control rod equivalent positionscheme proposed in this work is an optimal option in the trade-off between computation time andaccuracy. The control position is crucial for accurate power distribution and void feedback coefficients inSMFRs. The results in this paper also show that the pin level power distribution is important due to theheterogeneous distribution in SMFRs. The fuel burnup distribution at the end of core life impacts theworth of control rods.
