The initial phase of reactor cooldown is accomplished by transferring heat from the reactor coolant system to the steam and power conversion system through the steamgenerator.
停堆初期（第一阶段）的冷却过程：通过蒸汽发生器将反应堆冷却剂系统的能量传输给二次侧的蒸汽。

And that could be pipe breaks maybe in the secondary system, maybe a steamgenerator tube leak and so forth.
那可能是管道泄漏，可能是在次级系统中，可能一个蒸汽发生器的管道裂开了等等。

This paper introduces operation models and the test method of the steamgenerator level control system.
