Compact small pressurized water nuclear power plant

This patent describes a nuclear reactor steam generating plant having a pressurized water reactor with means for discharging hot primary coolant therefrom to a steam generator, the means for discharging having a pressurizer unit connected thereto, wherein the hot primary coolant is directed to the steam generator and cooled in the steam generator by heat transfer through tubes to a secondary coolant, and the primary coolant is returned from a channel head of the steam generator to the pressurized water reactor through a return line, comprising: a single discharge line to discharge primary coolant to the steam generator; means provided in the steam generator to divide the cooled primary coolant into a pair of streams comprising a T-shaped divider plate in the channel head comprising a plate and a laterally extending extension, the plate of which divides the channel head into an inlet section and an outlet section and the laterally extending extension of which divides the outlet section into two subsections
