英文摘要：

Containment is an important safety device for the protection of nuclear reactors. Visualization for measurement data or simulation data of the containment can help discover potential security issues. This paper introduces a mesh generation method and a physical data visualization method by leveraging cylindrical coordinates to represent the shape of the containment. By setting one-dimensional attribute of the cylindrical-coordinate system, the cross-section and longitudinal-section representations of mesh cells are illustrated. By using an Octree structure to store cells, the presented approach achieves good space performance and time performance. By setting one or more dimensional attributes, line and section representations for the physical data are obtained. Experimental results show that the proposed method can depict the running of the containment in real-time, simulate the physical laws of the containment effectively, and therefore ensure the safety of nuclear reactor.
