During normal, full-power operation, the neutron population in a core is stable (remains the same) and the reactor is in a critical state.
在通常的全动力应用下，内核里中子的产量是稳定的（保持一个数量不变），反应器处于临界状态。

The power coefficient of reactivity (PCR) is a measure of whether a particular reactor's nuclear neutron population will tend to increase or decrease after an increase in the reactor's power.
PCR是一座反应堆的核中子数会在反应堆能量增加后增加或减少的衡量标志。
