Abstract: Many pressure vessels and equipment components encounter elevated temperature and cycling loading simultaneously in modern industry, especially in nuclear power industry, petro-chemical industry and coal-chemical industry. In such cases, creep-fatigue interaction should be considered. In this paper, creep-fatigue evaluation of OCP reactor was performed according to ASMEIII-NH Code using ANSYS Workbench software; Design concept and detailed procedure were introduced; effect of creep and fatigue on design life respectively was summarized. Finally, suggestion was proposed that creep-fatigue evaluation method should be incorporated into Chinese Standard of design by analysis to satisfy fierce demand from nuclear power industry, petro-chemical industry, etc.
Keywords：Creep-fatigue, Finite Element, Design by Analysis, Reactor
