This paper introduces at first the structure of the pressurized vessel for AP600, which was developed by University of Wisconsin, and the stress and tightness of the pressurized vessel are analyzed. Then an improved structure of the pressurized vessel is developed so that the pressurized vessel can support a higher pressure for the experimental test of steam condensation on the cold surface. The stress of the improved pressurized vessel is analyzed by ANSYS. The calculation result shows that the pressurized vessel can not only support a higher pressure but also meet other thermal measurement requirements of the test.
