Abstract

Abstract

Loss of offsite power is an initiating event that takes place often in the nuclear power plant. The effect of power recovery on the frequency of each sequence shall be taken into account in the event tree of loss of offsite power. In this paper, the method of calculating the unrecovery factors of different frontier systems is discussed.
- Loss of offsite power,
- Event tree,
- Power-unrecovery factor
