1·The reactor vessel constitutes the main part of pressure boundary of primary coolant.
反应堆压力壳构成了主冷却剂压力边界的主体。
2·When you have an event, the reactor is operating at full power, you blowdown the primary coolant which is hot, you start injecting emergency core cooling water which is cold.
当你进行的时候，反应堆就会用全部的动力，运行，你排放出初冷却剂，那是热的，你开始注入紧急核心冷却水，那是冷的。
3·We also need to cool the reactor and the spent fuel in the spent fuel pool but that basically means you wanna maintain the coolant inventory which means water in the primary system.
我们也需要冷却反应堆，还有乏燃料,在乏燃料池里，但是那基本上意味着,你们想要维持冷却剂存货,也就是在主系统中的水。
4·There are reactor coolant system weld issues, they're used and they're getting primary water stress corrosion cracking.
还有反应堆冷却剂系统焊接问题，它们使用了并且得到原生水,应力腐蚀裂痕。
5·The entire primary loop of the nuclear reactor - the pressure vessel, pipes, and pumps that contain the coolant (water) - are housed in the containment structure.
整个最初的核反应循环是这样的——高压管、管道、泵、冷却剂(水)——这些被安装在容器型建筑中。
6·The running inertia of the main coolant pump is the key problem of the primary phase.
主循环泵转动惯量的取值是停堆初期冷却阶段的关键问题。
7·The results show that heaving has less effect upon the primary Loop's coolant flow rate and PWR output power in case of forced circulation but strongly influences natural circulation ability.
结果表明：起伏对强制循环下一回路冷却剂的流量和反应堆输出功率的影响较小，而对自然循环能力的影响很大。
8·This pump supplies make-up water to maintain the volume when the primary reactor coolant has contracted due to decrease of load.
该泵在主回路冷却水减少时，提供补充水以维持所需水量。
9·This pump removes the heat of the primary reactor coolant after the reactor is stopped and lowers its temperature.
该泵用于在反应堆停止时排除主回路的热量并降低其温度。
10·Also it supplies sealing water to the sealed part of the primary reactor coolant pump.
同时该泵还向核主泵提供密封水。
