摘要
对输入小阶跃反应性(ρ0<β)有温度反馈时,反应堆缓发超临界过程进行了研究。在功率与温度关系中考虑初始功率的作用,修正了绝热模型,求得了任意初始功率条件下反应堆反应性和功率随时间的变化规律,并进行分析、讨论。结果表明,初始功率对缓发超临界过程反应性与功率变化的影响明显,初始功率越大,反应堆反应性与功率的响应越快,且功率变化幅度也越大。
The delayed supercritical process of nuclear reactor with temperature feedback and initial power while inserting small step reactivity(ρ0〈β)is investigated. The effect of initial power in the relation between power and temperature is considered, and the adiabatic model is improved. The variations of the output power and reactivity with time are obtained. The analytic results show the effect of the initial power on the output power and reactivity during the delayed supercritical process is evident. The larger the initial power is, the quicker the reactivity and power respond, and the larger the power varies.
