abstract

A large scale pressurizer is used in III+ generation Nuclear Power Plant (NPP) which requires a high safety standard. The finite element method was adopted in this study to analyse and evaluate a III+ NPP pressurizer. A 2D integral symmetric model was created for the Upper Head, Lower Head and Shell which comprise the pressurizer. The typical Safety Relief Nozzle was selected to be representative of the nozzles in this analysis. A 3D local model was created for the Safety Relief Nozzle. The pressurizer was loaded under design condition to test its structure integrity and was further evaluated by American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME B&PVC) [1]. Furthermore, a model optimization method was proposed for the 3D nozzle model under ANSYS Workbench. The results showed that the pressurizer stress analysis fully met the ASME B&PVC criteria under design condition. The model optimization method was demonstrated to be valid and could be used for nozzle analysis and evaluation.
