The pressure relief valves form the isolation between the pressure relief duct and the vacuum building. They are designed to open automatically when the pressure in the relief duct rises to just above atmospheric (typically at ~3.5-7 kPa (g]. There are, typically, 12 to 20 such valves depending on the station. The majority are termed Pressure Relief Valves (PRV), and three or four, depending on the station, are Instrumented Pressure Relief Valves (IPRV). 1, record 2, English, - pressure%20relief%20valve

La pression augmente parfois plus rapidement que ce que le système de contrôle peut supporter. Des vannes de décharge permettent alors d'éviter que la pression entraîne une rupture des conduites. VDV (vanne de décharge de vapeur) restée ouverte. Si une VDV demeure ouverte, le caloporteur est perdu hors du circuit. Les vannes de décharge constituent l'isolement entre la conduite de décharge et le bâtiment sous vide. Elles sont conçues pour s'ouvrir automatiquement lorsque la pression dans la conduite de décharge augmente jusqu'à une valeur juste au dessus de la pression atmosphérique (habituellement ~3,5 à 7 kPa (manométrique]. On dénombre habituellement 12 à 20 de ces vannes selon la centrale. La majorité d'entre elles sont des vannes de décharge (VD), et trois ou quatre d'entre elles, selon la centrale, sont des vannes de décharge avec instruments (VDI). 1, record 2, French, - vanne%20de%20d%C3%A9charge%20de%20vapeur
