Keywords:Seismic evaluation, Fast reactor, Thin wall tee, Finite Element method

The equipment and piping in nuclear power plants receive seismic load from various directions during earthquakes. Understanding the load direction that most affects the structural strength of piping is an important for evaluating the seismic integrity of piping. In this paper, focusing on thin wall tee applied in fast reactor, some result of analytical evaluation of impact on structural strength of a thin wall tee is reported.
