核电工程建设中焊接及热处理温度对混凝土的影响

Assessment and Control Methods for the Impact of Welding and Heat Treatment Temperature on the Concrete of AP1000 Nuclear Power Plant

文章通过系统梳理和总结AP1000三门和海阳4个核电机组施工中,由于施工逻辑要求、设计制约和设计修改等因素,导致某些部件安装时需要考虑焊接和热处理热量对混凝土影响的案例和控制方法,为后续机组和项目提供了理论和实践经验。文章案例基本覆盖了AP1000施工中遇到的此类问题,并通过施工质量和过程数据得到了验证。

This thesis sorts out and summarizes the cases and control method of heat impact on the concrete during welding and heat treatment for installation of some components due to the requirement of the construction logic, design restriction, design modification, etc. in the construction process of four nuclear power units at AP1000 Sanmen and Haiyang, so as to provide theory and practice experience for the follow-up units and projects. The cases in this thesis almost cover this kind of issue during AP1000 project construction which have been verified through the construction quality and process data.
