低温供热堆温度系数的计算研究

Calculation of temperature coefficient for NHRs

本文介绍了供热堆反应性温度系数的计算方法，以２００ＭＷ堆为设计实例，计算了初装堆芯的燃料温度系数和慢化剂温度系数。同时，对于首炉运行工况下的温度系数作了比较细致的计算，这些计算结果为低温堆物理设计提供了科学依据。

The calculating method of temperature coefficient of reactivity for NHRs ispresented in this paper. An example case has been made for 200MW heating reactor.The fuel and moderator temperature coefficients were calculated for initial -- loaded coreand for the first cycle. The results provide a basis for the reactor safety analysis.
