Severe Accident Analysis of a Station Blackout Accident Using MAAP-CANDU for the Point Lepreau Station Refurbishment Project Level 2 PSA

Abstract

A Level 2 Probabilistic Safety Assessment was performed for the Point Lepreau Generating Station, using the MAAP CANDU code to simulate the progression of severe core damage accidents and fission product releases. Five representative severe accidents were selected: Station Blackout, Small Loss-of-Coolant, Stagnation Feeder Break, Steam Generator Tube Rupture, and Shutdown State. Analysis results for the reference station blackout accident are discussed in this paper.
