核反应堆最小烧毁比计算的新方法

A new method to calculate DNBR_(min)

用传统算法求得最小烧毁比的值总是大于实际值,使计算结果偏于危险.根据实验测量的实际情况提出了一个新的算法,克服了上述缺点,这对反应堆热工设计与安全分析都有重要的意义.

The DNBR_(min) got from traditional method is always greaterthan the practical result, and it makes the calculationleant todanger. On the basis of the practical measurement in the experiment, a new calculation method is brought forward in the thesis. It can overcome the abovementioned defect, and it is very important to the reactor′s thermal design and safety analysis.
