英文:
The emergency core cooling system (ECCS) is designed to cool the reactor core and provide additional shutdown capability following loss of coolant accident (LOCA), steam generator tube rupture, or main steam line break. It is divided into several subsystems consisting of both active systems and passive systems in operating nuclear power plant.
译文:应急堆芯冷却系统（ECCS）的功能是在发生冷却剂丧失事故、蒸汽发生器传热管破裂事故、或主蒸汽管道破裂事故后，来冷却堆芯并提供附加的停堆能力。它由若干个子系统组成，目前运行的核电厂中，既有能动系统，又有非能动系统。

英文:The high Head Injection System utilizes the centrifugal charging pumps to deliver water from the refueling water storage tank through the boron injection tank to the reactor coolant system at the prevailing reactor coolant system pressure. The Intermediate Head Injection System, also referred to as the Safety Injection System, utilizes two safety injection pumps to deliver water from the RWST to the Reactor Coolant System cold or hot legs.
译文:高压安注系统利用化容系统的上充泵作为高压安注泵。在电厂正常运行时这些泵在化容系统中正常充水；在事故工况下，这些泵在当时的反应堆冷却剂系统压力下，从换料水箱取水，通过硼注箱，向反应堆冷却剂系统注水。中压安注系统也叫安注系统，使用两台安注泵。在收到专设安全设施触发信号，泵将启动，将水泵回换料水箱重复循环，直到反应堆冷却剂的压力降到泵的排水压力之下，再将换料水箱的水唧送到反应堆冷却剂系统的冷管段或热管段。

No.3
英文:The operation of the emergency core cooling system following a loss of coolant accident can be divided into three modes: injection mode, cold leg recirculation mode, and hot leg recirculation mode.
译文:失水事故后应急堆芯冷却系统的运行可分为三个不同的模式：(1)冷段注入模式，各种动作基本自动完成，操纵员只需加以确认。(2)当换料水箱水位降至某低水位，安注进入冷段再循环注入模式（自动），此时低压安注泵吸水口转向安全壳地坑。(3)热段再循环，提供反向流动，以除去燃料元件表面出现的硼酸结晶。（此段做了相应解释，非完全直译）
郑宗宇 (Monica)
I am a bubbly character who have a positive outlook on life, a sense of purpose and community. And I love to exchange ideas with my friends, which makes me feel relax during spare time.
I used to be fond of sports, but nowadays I am coffee-and-dessert-obsessed. That is why I am badly in need of doing exercise to keep fit these days. I enjoy reading and travelling, where I can discover another me and the potential inside myself.
