In the primary piping systems of nuclear power plants, many valves with bellows in their seal systems are used in order to prevent the leakage of high-pressurized and high-radioactive coolant. The Ω-bellows for high-pressure valves hold rings in them in order to heighten their compressive stiffness and reduce stresses. The contact and frictional effects between the bellows and the rings prevent their stress analyses. In this paper, we analysed stresses in Ω-bellows using the finite element program applicable to contact problems, and then estimated fatigue strength for 2 types of load histories. The comparison with the results of fatigue tests shows that the locations of fatigue cracks can be predicted by the analysis.
