And basically it says that if you have core a design you wanna be able to make sure that the inherent nuclear feedback characteristics can deal with and compensate for prompt reactivity excursions.
基本上也就是假如你有一个核心设计，你想能够保证固有的，核反馈的特点是能够处理，并补偿即时反应骤增。

The results indicate that fuel temperature changing more slowly than nuclear power makes reactivity negative feedback not to restrain power changing, and then power concussive progress comes to being.
