| 中文摘要: |
| 基于我国首个核电站淡水水量平衡测试的成果，通过解读核电站用水工艺流程，分析了核电站在正常运行期及大修期各用水项（包括总用水、核岛及常规岛用水、厂内生活用水、澄清池轴封用水、循泵轴封用水与冲洗用水等）的用水特征及规律，挖掘各用水项与生产工艺之间的内在联系及特点，推算各用水项与电厂发电量、装机容量等参数之间的关系。分析结果表明，两台二代百万千瓦核电机组年淡水实际用量不及设计值的1/3；核电用水环节中常规岛用水量最大，约占总用水量的30%；核电用水量与发电量并无明显的相关性，其单位发电量取
水量及装机容量取水量值较小，不及火力发电行业限值的30%。该成果可为核电站的用水设计提供参考，并为今后核电项目的水资源论证管理及取水定额的制定提供依据。 |
| 英文摘要: |
| In consideration of the lack of water quota standards in nuclear-power industry， water resources argumentation for nuclear projects has faced difficulties which affect the water license approval and management for them. Supported by the Ministry of Water Resources （MWR） and China Guangdong Nuclear Power Holding Co.， Ltd （CGNPC）， the first fresh water balance test in nuclear project has been carried out in China. Base on the test results， the characteristics of water consumptions were analyzed， including total water consumption， nuclear island and conventional island water consumption， domestic water consumption in-plant，circulating pump water consumption and rinse water consumption by interpreting the common treatment of water in nuclear power plant during normal operation periods and overhaul periods. The results show that the annual fresh water consumption of the two sets of the second-generation nuclear power units with capacity of million-kilowatts is less than even 1/3 of the designed value. The water consumption in the conventional island is the maximum one， taking almost 30% of the total value. There is no significant correlation between water consumption and power output in nuclear power plant. The water withdrawals per unit power generation and per unit installed capacity are far more less than 30% of the limit of thermal power plant. The research findings could provide references for water design and formulating water quota standards in nuclear-power industry. |
