This paper shows consideration of respective median and uncertainties of realistic response and realistic capacity of SSCs which are necessary for the fault displacement fragility evaluation. And based on the fragility evaluation methodology presented in the last annual meeting, fragilities of SSCs of a hypothetical NPP are quantified. In addition, a procedure to develop a battery of input for the accident sequence evaluation is presented.
