An overview on the probabilistic safety assessment (PSA), the loss of external power source connected to the nuclear power plant

Abstract

Loss of Offsite Power source connected to the nuclear power plant (LOOP) as the starter event and consequently the probability Station Blackout (SBO) are among accidents that are considered in the Probabilistic Safety Assessment (PSA) and have a significant impact on the melting frequency of the reactor core. Thus, in this paper, the Probabilistic Safety Assessment (PSA), the loss of the external power source in the nuclear power plant is investigated.
