1、These models have established the solid foundation for the further study whole primary loop's dynamic performance.───这些模型的建立为进一步研究整个一回路的动态特性和控制XiTong特性奠定了坚实的基础。
2、water in the primary loop circulates, it becomes very hot.───水在主环的循环中变热。
3、Steam within the primary loop, now no longer circulating with the water, rises.───主回路中的蒸汽，不再同水一起循环，而是升腾起来。
4、45 min The water level in the primary loop continues to drop. Gauges in the control room erroneously indicate that the water level is up.───45分钟主回路的水位继续下降。控制室中的仪表误报水位在上升。
5、Half of the core is now uncovered, and the radioactivity of the water in the primary loop is 350 times its normal level.───堆芯的一半都暴露在水面上，主回路中水的辐射水平达到正常标准的350倍。
6、The seismic analysis for reactor coolant piping (RCP) primary loop is one of the very important work in design of nuclear power plants.───核电站反应堆冷却剂XiTong地震分析是核电设计中一项十分重要的工作。
7、45 min the water level in the primary loop continues to drop.───45分钟主回路的水位继续下降。
8、Also, there's still hydrogen in the primary loop.───此外，主回路中还存在氢气。
9、15 hr 50 min The primary loop's pumps are turned on, which circulate water around the core.───15小时50分钟随着主回路的水泵启动，循环水包围了堆芯。
1、2 sec Because heat is no longer being transferred to the secondary loop, water pressure and water temperature in the primary loop rise. This is normal and no cause for concern.
