核电站维修的三维数字化动态管理

3D Digital Dynamic Management of Maintenance Projects for Nuclear Power Plant

详细介绍了数字电厂技术在大亚湾核电站反应堆厂房内设备的转运和空间布置动态管理中应用的全过程,论述了大亚湾三维数字化动态管理的建立及其在核电站维修项目中应用的方法和主要步骤。本项目利用外部数据库对电厂维修的模型状态进行保存,避免了对原有三维竣工模型的破坏和变动;紧密结合核电厂维修工作的主要进度步骤,对核电厂维修工作的空间布置和进度计划进行了全过程的仿真和优化,在核电厂维修工作中,较好地解决了在有限空间内进行维修空间计划安排和布置的仿真和优化问题。并在大亚湾核电厂2号机组更换反应堆顶盖中成功地进行了应用,缩短关键路径工期16小时,总工期缩短92.5小时。

The whole process for the application of digital plant technique in the equipment transport in reactor building and the dynamic management of the spatial arrangement in Daya Bay Nuclear Power Station was introduced in the paper. The establishment of 3D digital Daya Bay plant, and the method and procedure to apply it in the nuclear power plant maintenance project have been discussed. This project utilizes the outer database to preserve the maintenance status of equipments, and avoids the damage or changing of the original 3D final model. Based on the maintenance procedure, the spatial arrangement and schedule for the maintenance of nuclear power station have simulated and optimized for the whole process. This technique can simulate and optimize the arrangement and spatial arrangement for maintenance in limited space. It has been applied successfully in the reactor vessel head replacement for Unit 2 of Daya Bay NPP to shorten the time for key routes and the total time of this project by 16 hours and 92.5 hours, respectively.
