In the master's thesis, we discussed various aspects of replacing a high-pressure steam turbine in a nuclear power plant. The main goal of the task was to investigate the logistical measures in the preparation phase for the replacement of the high-pressure turbine. For this purpose, we created a 3D model of a high-pressure steam turbine, its steam pipelines, concrete foundation and all four control valves. To create a credible computer model, we performed a 3D laser scan of the entire turbine section of the plant. When planning the replacement of the high-pressure steam turbine, we analyzed the building structure for space constraints using the 3D model. We made a 3D model of additional steam pipeline supports. We also determined the location of cutting and welding of steam pipelines. Using the 3D model, we also analyzed and proposed procedures for replacing a high-pressure steam turbine.
