Design of Radial and Axial Fuel Shuffling TWR

  • 摘要: 给出了径向和轴向倒料行波堆堆芯的详细设计,通过燃耗计算软件MCORE对两种堆芯进行了分析计算。对于轴向行波堆,得到了稳定的核子密度分布和功率分布,并模拟出增殖-燃耗波。稳态时,keff 为1.065,波速约为5.0 cm/a,燃耗深度达到400.0 MWD/kg-HM。对于径向倒料行波堆,采用由外向内的倒料方案,经过一定倒料周期后功率分布趋于稳定。研究发现,渐进稳态keff 随倒料周期的增加呈抛物线变化,燃耗深度随倒料周期的增加线性增大。以最低功率峰为依据,确定倒料周期450 d为最佳倒料周期。此时,渐进稳态keff为1.020,平均燃耗达到156.0 MWD/kg-HM。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.
