The temperature oscillation produced by thermal stratification phenomenon induces thermal fatigue damages on structures of nuclear components, which should be prevented. To evaluate thermal fatigue, the frequency response function was developed. However, this theoretical method does not take particular effects of thermal stratification oscillation into account. To clarify these effects, finite element simulations were conducted with two fluid temperature models. Based on mechanisms of the effects, the frequency response function was improved. Agreement with the results of the finite element simulations confirmed the proposed function.
