通过防止压力窗口钢质的脆化，从而延长了核反应堆芯的寿命，有些反应器寿命更是长达40-50年。
This prolongs the reactors core life by preventing the embrittlement of the steel of the pressure vessel, with some reactors being designed to last between 40 and 50 years.
只要控制棒能够控制反应，并且冷水可以被连续泵回反应器，那么反应堆就可以在一个安全的温度下一直运行。
The reactor will operate at a safe temperature as long as the control rods are able to control the chain reaction and cool water is pumped into the reactor continuously.
他说，海水冷却反应堆正将1和3泵浦-这是恢复正常-进入反应器2，这仍然是不稳定的。
He said cooling seawater was being pumped into reactors 1 and 3 - which were returning to normal - and into reactor 2, which remained unstable.
