摘要
利用蒙特卡罗程序对净堆临界和运行转载冷态下的安全棒和补偿棒的单棒价值以及棒组价值进行理论计算,同时通过落棒法和周期法对安全棒和补偿棒价值进行试验测量。经比较可看出,试验值与理论值吻合很好,两者的误差在5%以内。计算结果表明,蒙特卡罗程序具有较高的计算精度,可为在后续大型快堆中的应用提供参考。
The reactivity worth of safety rods and shim rods in critical phase and operating phase was calculated respectively using Monte Carlo program in this paper.In addition,the reactivity worth of safety rods and shim rods was measured by the rod drop-off method and period method.The experimental results are in good agreement with the calculated values with less than 5% error.It illustrates the high calculation precision of Monte Carlo program,which provides a practical reference for subsequent application of Monte Carlo program in future demonstration fast reactors.
