概要
Fluid temperature fluctuates at an incomplete mixing area of high and low temperature fluids in nuclear components. It induces random variations of local temperature gradients in structural walls, which lead to high cyclic thermal fatig ue damage. Since this phenomenon is a complex fluid-structural interaction problem, evaluation methods were developed in each field. In order to integrate above methods into maintenance engineering, their synthesis approach is proposed.
