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。
In this paper, the calculation method of the reactor temperature coefficient is introduced. Taking the 200MW reactor as an example, the fuel temperature coefficient and moderator temperature coefficient of the initial reactor core are calculated. At the same time, the temperature coefficient under the first furnace operating condition is made more detailed calculation. These results provide the scientific basis for the physical design of cryogenic reactor.
