Abstract
In this research, we propose a new index “The Resilience Index” to evaluate the capability of nuclear power plant to recover from the safety function loss situation. Three elements were assumed in order to evaluate the resilience index. These are the required function fulfilment rate L, necessary elapsed timeT, and probability of success X, for each accident management activity. The resilience index is expected to visualize the improvement of safety of each nuclear power plant against severe accidents.
