In nuclear power plants, there are many T-junctions at which different temperature fluids are mixed. When the fluids with different temperature are mixed, temperature fluctu ation in fluids reachs wall and high-cycle heat fatigue occurs. Depending on amplitude and frequency of temperature fluctuation, it could lead to pipe rupture accident at wo rst. In addition, in case of the T-junction with 90-degreee bend at upstream, there is higher risk for pipe rupture accident due to secondary flow which arises in ...
