The pressure relief system protects the heat transport system piping from mechanical overpressure. Overpressure could occur, for example, if the feed valves failed to open, allowing the full discharge pressure from the feed pumps to pressurize the system. Relief valves that discharge coolant directly from the reactor outlet header into the bleed condenser provide the protection. 1, record 1, English, - pressure%20relief%20system

Le système de protection contre la surpression protège les conduits du circuit caloporteur contre la surpression mécanique. La surpression peut survenir, par exemple, lorsque les vannes d'alimentation demeurent ouvertes, ce qui fait en sorte que la pression de décharge des pompes d'alimentation exerce une pression sur le circuit. Les vannes de décharge qui amènent directement le caloporteur depuis le collecteur de sortie du réacteur vers le condenseur de purge assurent une certaine protection. 1, record 1, French, - syst%C3%A8me%20de%20protection%20contre%20la%20surpression

Where power-actuated relief valves are connected to instrumentation associated with one or both shutdown systems, the credit which may be given to these valves under conditions of shutdown system impairment must be specified in the overpressure protection analysis. 1, record 2, English, - power%2Dactuated%20relief%20valve

Lorsque les soupapes de décharge à servo-commande sont reliées aux instruments associés à l'un des systèmes d'arrêt d'urgence, ou des deux, il importe de préciser, dans l'analyse de protection contre la surpression, les limites d'efficacité de ces soupapes en divers cas de défaillance d'un système d'arrêt d'urgence. 1, record 2, French, - soupape%20de%20d%C3%A9charge%20%C3%A0%20servo%2Dcommande

Because the reactor shutdown systems form part of an integrated overpressure protection system, it is necessary to define the role of each of the shutdown systems(and of each trip parameter) in the integrated system. 1, record 3, English, - overpressure%20protection%20system
