时空中子倍增公式解法研究

通过将空间概念引入中子倍增公式， 建立了时空中子倍增公式， 针对时空中子倍增公式计算时间效率过低的缺点， 对时空倍增公式的计算方法进行了研究， 新解法在保证精确性的基础上， 又提高了计算效率。新的计算方法可以应用于研究反应堆反应性发生动态变化的情况， 例如反应堆启堆或停堆以及变功率运行的过程， 对具有很强机动性要求的小型反应堆的安全分析有一定的理论意义和实用价值。 The space time neutron multiplication formula was established by introducing the concept of space time to the neutron multiplication formula. Because of the rather long computing time by using the formula, the solution of space time neutron multiplication formula is optimized which is efficient and accurate. The new method can be used to study the reactor with dynamic change in reactivity. It can be also used for studying the process of startup, outage and power drawn operation, which is of great importance to the safety analysis of the mini nuclear reactor.
