The improvement of the evaluation method in the seismic probabilistic risk assessment (: PRA) for the fast reactor is investigated. In the improvement of the evaluation method, the evaluation method, which can evaluate the failure of the important components such as reactor vessel, is necessary. Accordingly, the method of failure probability evaluation with integrated vibration energy is developed in this study. In this report, integrated vibration energy until specimen is failed by vibration is discussed based on the results of fatigue tests.
