Abstract: In the fields of nuclear and thermal power generation, as well as the chemical industry, etc., pipe welding defects are often difficult to be detected due to the reachability of the inspecting tools. Therefore, it is of great importance to solve this problem during the design stage. Based on the 3D design platform, a design tool for pipe welding non-destructive testing(NDT) is developed for nuclear power plants. The tool, which combines the NDT related parameters and space demand in 3D environment, realizes the reachability simulation and the automatic generation of inspection list for welding NDT, therefore, improves the design quality and efficiency substantially. The proposed methodology, i.e., 3D simulation of NDT space demand, which, for the first time, integrates the welding NDT demands into 3D layout design in pre-construction phase, can eliminate the risk due to inspection reachability.
