1. The purpose of the Component System is to remove heat from systems which may contain radioactive water such as the Reactor Coolant System, Chemical and Volume Control System and residual Heat Removal System, etc. to the Essential Raw Cooling Water System for release to the environment.

 

　　1. 设备冷却水系统的主要功能就是将带有放射性水系统的热量导出，如主系统、化容系统和停冷系统等，通过海水系统排向环境。

 

　　2. The Component Cooling System is a closed loop, so it as a barrier between radioactive systems and the environment.

 

　　2. 设备冷却水系统是封闭式循环系统，因此在放射性系统和环境之间提供了一个屏障。

 

　　3. The operated at lower pressure than any system with which it interfaces, so it will collect leakage.

 

　　3. 它的运行压力低于放射性系统的压力，因此可以接受放射性系统的泄漏。

 

　　4. The typical Component Cooling System is used during all phase of plant operation, including shutdown and post-accident.

 

　　4. 设备冷却水系统用于电厂的所有运行阶段，包括停堆和事故后处理。

　　5. 典型的设备冷却水系统由设冷泵，热屏蔽水泵，热交换器，设冷泵密封水收集器和相关的阀门，管道和仪表组成。

 

　　6. The typical Component Cooling System consists of the system water due to temperature changes or inleakage, as well as providing a continuous water supply until a small leak in the system can be isolated.

 

　　6. 设备冷却水系统能够补偿温度变化或放射性系统向设冷水系统的泄漏，同时在系统发生可隔离的小破口泄漏时，仍能提供连续的供水。

 

　　7. The function of thermal barrier booster pumps is to circulate cooling water through the reactor coolant pump thermal barrier.

 

　　7. 热屏增压泵的作用是给主泵热屏提供循环冷却水。

 

　　8. The Essential Raw COOLING Water System (ERCW) also called the service water system is used during all phases of operation to remove heat from essential and non-essential loads, such as emergency diesel generators, containment ventilation system.

 

　　8. 重要厂用水系统的作用是在运行的各个阶段将安全和非安全负荷的热量导出，如EDG，安全壳通风系统。

 

　　9. The ERCW is an open system, using water from the environment and discharge back to the environment.

 

　　9. 重要厂用水是个开式系统，从环境取水，用完后排放回环境。

 

　　10. The Condenser Circulating Water System supplies cooling water to the condensers to condense exhaust steam from the low pressure turbine and to the Raw Cooling Water System.

 

　　10. 循环水系统用于冷却低压缸的乏汽，并向非重要厂用水系统供水。

 

　　11. The Raw Cooling Water System is non-essential system which is provides for removal of heat from turbine building loads, as well as some non-essential loads in the auxiliary building.

 

　　11. 非重要厂用水系统是非安全系统，用于汽机厂房和辅助厂房内非安全负荷的热量导出。

 

　　12. The Spend Fuel Pit Cooling System is designed to remove the decay heat generated by stored spend fuel assemblies and to purify the water in the spent fuel pit.

 

　　12. 废燃池冷却系统用于导出乏燃料组件的衰变热，同时净化乏池内的水质。
