This paper reports current efforts to establish a JSME code for the evaluation of high-cycle thermal fatigue for thermal striping in mixing tees with hot and cold water. The proposed design evaluation method has four steps to screen the design parameters one-by-one from the viewpoint of the severity of the thermal load predicted from design conditions. Five charts were produced by thermal striping tests for broad operating conditions of actual LWR power plants and a thermal stress model considering the effects of boundary layer attenuation for fluid temperature fluctuation, in order to realize the design evaluation method.
