Creators

Description

The nuclear boiler described includes a pressure vessel housing the core of the boiler closed at its upper part by a cover. A primary coolant flows through it. It also contains a number of pumps to move the liquid. This boiler comprises a massive circular part forming the upper section of the side shell of the vessel. This part is provided with a number of radial through holes equal in number to that of the generators fixed to the connecting side opposite the radial holes. The circulation pumps are integral with the water tank of the steam generators. Each generator has at least one pump the casing of which is integral with the water tank of the steam generator

Abstract (French)

On presente une chaudiere nucleaire comportant une cuve de resistance a la pression contenant le coeur de la chaudiere fermee a sa partie superieure par un couvercle. Il y circule un liquide primaire de refroidissement et une pluralite de pompes pour mettre en mouvement le liquide. Cette chaudiere comprend une piece massive de revolution constituant la partie superieure de la paroi laterale de la cuve, cette piece etant percee d'une pluralite d'orifices radiaux la traversant de part en part. Le nombre des orifices radiaux est egal au nombre des generateurs qui sont fixes sur la face de raccordement au droit des orifices radiaux, et les pompes de circulation font partie integrante de la boite a eau des generateurs de vapeur. Chaque generateur de vapeur est equipe d'au moins une pompe dont la volute est confondue avec la boite a eau du generateur de vapeur
