摘要

提出了含有反射中子的快脉冲堆中子动力学方程,并据此开展了快脉冲堆在超瞬发临界状态下产生脉冲的数值模拟计算。结果表明,反射中子增加了反应性和脉冲产额,由于反射中子使脉冲波形展宽,波形也不再对称。
        The neutron dynamic equations of fast pulse reactor including reflected neutrons were put forward.The pulse wave that fast pulse reactor burst at prompt supercritical state was simulated.The results show that the reactivity is increased and the fission yield is enlarged by reflected neutrons,the pulse wave is not symmetry since it is broadened by reflected neutrons.
