Abstract
In an illustrative embodiment, a pressurized water nuclear reactor (PWR) includes a pressure vessel (), a nuclear reactor core () disposed in the pressure vessel, and a vertically oriented hollow central riser () disposed above the nuclear reactor core inside the pressure vessel. A once-through steam generator (OTSG) () disposed in the pressure vessel includes vertical tubes () arranged in an annular volume defined by the central riser and the pressure vessel. The OTSG further includes a fluid flow volume surrounding the vertical tubes and having a feedwater inlet () and a steam outlet (). The PWR has an operating state in which feedwater injected into the fluid flow volume at the feedwater inlet is converted to steam by heat emanating from primary coolant flowing inside the tubes of the OTSG, and the steam is discharged from the fluid flow volume at the steam outlet.
