Abstract
A nuclear reactor system is described wherein a prestressed concrete reactor vessel is provided with a main cavity for the reactor core and at least one subsidiary cavity for a steam generator. At least two feedwater penetrations are provided in the reactor vessel communicating between the exterior of the reactor vessel and the subsidiary cylindrical cavity. A superheater penetration is provided aligned with the axis of the cavity with the feedwater penetrations and the superheater penetration having mutually parallel axes. Superheater outlet means are positioned in the superheater penetration and include a tubesheet positioned a substantial distance from both the subsidiary cylindrical cavity and the exterior of the reactor vessel.
Claims6
In a nuclear reactor system having a prestressed concrete reactor vessel with at least one cylindrical cavity therein for a steam generator including a feedwater tubesheet and a superheater tubesheet, the improvement comprising at least two feedwater penetrations in said reactor vessel communicating between the exterior of said reactor vessel and said cylindrical cavity, said feedwater penetrations having mutually parallel axes parallel to an extension of the axis of said cylindrical cavity, feedwater inlet means in said feedwater penetrations, a superheater penetration communicating between the exterior of said reactor vessel and said cylindrical cavity, said superheater penetration having an axis parallel to the axes of said feedwater penetrations and being substantially aligned with the axis of said cylindrical cavity, and superheater outlet means in said superheater penetration, said superheater outlet means including a tubesheet positioned in said superheater penetration a substantial distance from both said cylindrical cavity and the exterior of said reactor vessel.
