摘要
在反应堆运行期间,为了能在给定的功率条件下稳定地运行,且能满足紧急停堆、功率调节、补偿控制等要求,必须引入各种形式的反应性。而确定需要引入反应性的数量和采用何种方式进行高效与安全的控制,以及各种控制类型之间反应性的分配,是核反应堆堆芯设计的一个十分重要的方面。为了搞清楚里面的控制机理和动态特性,下面对各种反应性进行了综合分析,建立了包括反应性反馈在内的物理模型,并运用此模型对反应堆功率进行计算,且对其稳定性进行了分析,得出了全面的控制机制和详细的动态特性。这对反应堆的堆芯设计、有效控制和安全运行具有重要的参考意义。
In order to operate stably in a given power condition and satisfy the emergency shutdown , power regu-lation, control compensation, the reactor must be introduced various forms of reactivity during operation .To make sure how much reactivity should be introduced and how to conduct the process safely and effectively ,and how the different kind of reactivity should be distributed is a very important aspect in the nuclear reactor core design.In order to make the inside control mechanism and dynamic characteristics clear , a comprehensive anal-ysis of variety of reactivity is conducted and established the physical model which includes the reactivity feed -back in the bellow.Furthermore,this model is used to calculate the reactor power and analyze the stability .It is concluded the comprehensive control mechanism and detailed dynamic characteristics .This is a very important reference for reactor core design , effective control and safety operation .
