The fast periodic pulsed reactor utilizes rotating reflectors to introduce periodic varying reactivity, making the core generate continuous power pulses at a certain frequency. The pulse parameters under stable operation are extremely important in measuring the performance of the reactor. The critical search method of calculating the pulse parameters is established, and in order to further study the factors affecting the pulse parameters, a new theoretical estimation method is proposed. The two methods are verified in the IBR-2 with PuO₂ as fuel, and the results are in good accordance with the experimental data. The fast periodic pulsed reactor FNPR with UO₂ as fuel is designed. The pulse parameters of FNPR are calculated by the verified methods and compared with those of IBR-2. The results show that in terms of parameter quality, FNPR is inferior to IBR-2. The method of improving FNPR pulse parameters is also discussed herein.

快速周期性脉冲电抗器利用旋转反射器引入周期性变化的反应性，使铁心以一定频率产生连续的功率脉冲。稳定运行下的脉冲参数对于测量反应堆的性能极为重要。建立了计算脉冲参数的临界搜索方法，为进一步研究影响脉冲参数的因素，提出 了一种新的理论估计方法。在以PuO ₂为燃料的IBR-2中对这两种方法进行了验证，结果与实验数据吻合良好。带UO ₂的快速周期性脉冲反应堆FNPR作为燃料的设计。通过验证的方法计算出FNPR的脉冲参数，并将其与IBR-2的脉冲参数进行比较。结果表明，就参数质量而言，FNPR劣于IBR-2。本文还讨论了改善FNPR脉冲参数的方法。
