- 86 - Series Events considered for the level 1 and 2 PSA 900 MWe reactors (CP0-CPY) Failures internal to the reactor (PSA 1 and 2) Fire (PSA 1) 1300 MWe reactors (P4-P’4) Failures internal to the reactor (PSA 1 and 2) For the review associated with the 3rd 10-year inspection, the following will also be considered: - events associated with the spent fuel pool building (BK) (EPS 1 and 2); - internal fire and flooding (PSA 1). 1400 MWe reactor (N4) Failures internal to the reactor (PSA 1). A level-2 PSA will be performed for the next safety review. 1650 MWe reactor (EPR) under construction The level 1 and 2 PSAs will be revised in view of the commissioning authorisation application. They will take into account: - the events internal to the reactor; - the events associated with the spent fuel pool building (BK); - earthquake; - internal fire and explosion; - internal flooding. Moreover, in the framework of the 3rd general review of the 1300 MWe reactors, a study was conducted to verify the possibility of extending the level-1 PSAs to earthquakes.
