4D模拟在核岛主回路设备安装中的应用

Application of 4D Simulation in the Installation of Nuclear Island Primary Loop Equipment

为了降低台山核电核岛主回路设备"空中翻转"及"倾斜就位"全新施工工艺首次应用中的潜在风险,探索出一种核岛主回路设备安装模拟方法,实现了对主回路设备安装的动态模拟、施工工艺验证,以及设备与土建结构的碰撞检查和间距量化,并成功应用于1号机组压力容器及稳压器等核岛主回路设备安装。

In order to minimize the potential risks during the first time application of new erection technology of 'flip in the air' and 'inclined introduction' for the nuclear island primary loop equipment, this paper presents a new approach of simulation to be used for the nuclear island primary equipment erection, which can perform dynamic simulation and process verification for primary equipment erection, and carry out collision inspection and space quantification between the equipment and the civil work structure of nuclear island building, and has been successfully applied for the installation of nuclear island primary equipment such as reactor vessel and Pressurizer.
