摘要
对输入大阶跃反应性(ρ0>β)和有温度反馈时的反应堆超瞬发临界变化过程进行研究。求得任意初始功率条件下反应堆反应性与功率的变化规律,并分析、讨论了输入反应性与初始功率大小对瞬发超临界变化过程的影响,给出一些有益的新结果,可为反应堆安全分析和运行管理提供重要的理论依据。
The prompt supercritical process of nuclear reactor with temperature feedback while inserting large step reactivity (ρ0 > β) was analyzed. The relationships between reactivity and time and between output power and time were derived, and the maximal power as well as the related reactivity and time were obtained. The affections of the inserted step reactivity and initial power on the prompt supercritical process were analyzed and discussed. Some useful new conclusions were drawn, which can provide an important theory for the safety analysis and operating administration of the nuclear reactor.
