岭澳核电站第1燃料循环WANO化学指标状况研究

Study on WANO chemistry performance indicator of 1st cycle in Ling'ao Nuclear Power Station

借用世界核营运者协会(WANO)制定的压水堆核电机组的化学指标体系,对岭澳核电站2台980MW压水堆机组第1燃料循环的二回路水质状况进行分析、研究,并与大亚湾核电站2台机组的水质比较以及法国电力公司14台同类机组第1燃料循环的水质做比较,得出岭澳核电站2台机组第1燃料循环的水质相对较好的结论。最后,总结了压水堆核电新机组的水质控制经验及其改善措施。

Making use of chemistry performance indicator definition of WANO (the World Association of Nuclear Operators),this paper studies and analyzes the secondary water chemistry of the 1st cycle of two 980 MW pressurized water reactor (PWR) units in Ling'ao Nuclear Power Station. Comparisons with the water quality of two units in Daya Bay Nuclear Power Station and with the 1st cycle water quality of 14 similar units of Electricite de France (EDF) show the superiority of the 1st cycle water quality of two units in Ling'ao Nuclear Power Station. Finally,some experiences in water chemistry control for new PWR units are summed up along with corresponding improving measures.
