Conceptual design criteria 方案设计标准
The number of pumps. how they are driven, design data, and control of the system, shall be chosen and submitted to the purchaser for approval to ensure, with safety and sufficient margins, all operating condition, in a manner compatible with the requirements of the NI supplier.
泵的数量、泵的驱动方式、设计数据和系统的控制应由购买者选择并提交给购买者审批以确保其安全和充足的裕度，所有运行条件都以符合NI供方要求的方式运行。
In particular:
特别是：
1. Feedwater pump design shall ensure satisfactory water supply to the steam generator during total load rejections or turbine trips.
1. 给水泵设计应确保在整个甩负荷或汽轮机跳闸期间蒸汽发生器的给水符合要求。
Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about Pump design standard.
华译网上海翻译公司曾经翻译过大量有关水泵方案设计标准的资料文件。
2. Feedwater pumps' associated instrumentation and controls shall be designed to ensure that the trip of one pump does not cause a steam generator low-low level reactor trip.
2. 给水泵的相关仪器仪表和控制装置应能够确保一个泵的跳闸不会造成蒸汽发生器低-低液位反应堆停堆。
3. The Supplier shall review all the transients of loss of feedwater pumps with steam generator supplier and the Purchaser. Reports shall be issued for review.
3. 供方应与蒸汽发生器供方和购买者一起审查给水泵损失的所有瞬态，并提交报告供审核。
4. The feedwater pumps shall be designed for continuous operation under all operating modes of the Unit, as specified in Section 3.1., Part 5 Chapter 3.
4. 给水泵应能够按照第3章第5部分第3.1节的规定在机组所有运行模式下持续运行。
5. The pumping sets shall be capable of stable operation either singly or in parallel at any point of their characteristic, between leak-off and run out.
5. 泵送机组应能够在（泄流和跑出之间）特征曲线上的任何点单独或并联稳定运行。
6. Exceptional operating conditions shall be transient conditions such as trip of a pump or of the turbine.
6. 异常运行条件应为瞬态条件，如泵或汽轮机的跳闸。
7. The system shall have the capability of providing the necessary increase in feedwater flow to the steam generators with the steam pressure increase resulting from a 100 % load rejection
7. 系统应有能力通过100%甩负荷产生的蒸汽压力增加实现蒸汽发生器给水流的必需增量。
