目前大亚湾现场运行的给水系统是在法国设计指导图基础上,由我国自行设计、施工的。经六年来的运行实践证明,设计中考虑施工用水与永久性生产、消防、生活用水结合,按功能分系统设置管网和选用不同管材等都是经济合理的。整个工程能满足各种用水需要。但由于设计时对中外标准和现场条件的差异认识不足,也存在实际用水量超过用水定额、主干管阀门设置过少、两组高位水池高度不一致等问题,给维护和管理带来了不便。
At present, the water supply system for Daya Bay’s on-site operation is based on the design guide map of France and is designed and constructed by China. After six years of operation, it has been proved that the combination of construction water use, permanent production, fire control, and domestic water use in the design, and the installation of pipe networks and the selection of different pipes according to functional sub-systems are all economic and reasonable. The entire project can meet a variety of water needs. However, due to the lack of understanding of the difference between Chinese and foreign standards and site conditions during design, there are also problems such as the actual water consumption exceeding the water quota, the main pipe valve setting too few, the inconsistency of the height of the two groups of high pools, and so on, which has caused inconvenience to maintenance and management.
