Description

A probabilistic study has been carried out to compare two designs for the safety-injection circuit of a pressurized-water reactor. It appears that unavailability of the circuit after an accident involving loss of coolant decreases little when one moves from a 2-line to a 3-line system. These results are compared with the disadvantages arising from increased redundancy, and in particular the increased cost of the installations. The 2-line circuit appears the optimum one on the basis of cost and reliability criteria. It has been chosen for the 1300-MWe units

Abstract (French)

Une etude probabiliste a ete faite pour comparer deux conceptions du circuit d'injection de securite d'un reacteur a eau sous pression. Il apparait que l'indisponibilite du circuit apres un accident de perte de refrigerant decroit peu quand on passe d'un schema a 2 files a un schema a 3 files; ces resultats sont compares aux inconvenients d'une redondance accrue, en particulier a la hausse du cout des installations. Le circuit a 2 files apparait etre optimise par rapport aux criteres de cout et de fiabilite. Il a ete choisi pour l'equipement des tranches de 1300 MWe
