Abstract: With the continuous expansion of nuclear energy capacity in China,the production of spent fuel from nuclear power plants has been steadily increasing.The storage and management of these highly radioactive materials are of critical importance.Once storage facilities are put into operation,it becomes difficult to conduct regular internal inspections and maintenance.Taking a nuclear power plant as an example,this study utilizes the Leica RTC360 3D laser scanner to obtain point cloud data of equipment rooms.The data are processed using Cyclone software,and by integrating the advantages of Cyclone for modeling regular objects and 3ds Max for irregular objects,a 3D model is successfully constructed.The modeling results provide an intuitive representation of the spatial layout and positioning of various equipment in the nuclear power plant,facilitating later maintenance and inspection tasks,thereby further enhancing the management and operational efficiency of the plant.Additionally,it has been confirmed that the 3D model constructed through the collaboration of Cyclone and 3ds Max offers advantages such as high efficiency,high precision,and broad applicability.
