Harand, E; Michel, E

In a nuclear reactor installation secured against rupture and has a pressurized water reactor, and a straight-tube steam generator having a central ascending pipe, a coolant pump and lines connecting them in a primary circulatory loop. The coolant pump is installed in a primary chamber of the steam generator and forms with the latter a structural unit, the primary loop having hot and cold lines between a pressure vessel enclosing the reactor and the primary side of the steam generator. At least part of the hot and cold lines are united along the direction of their fluidic flow paths, the structural unit formed of the pump and the steam generator being upright with relatively short, straight and horizontal primary loop lines. A protective sheathing is provided to prevent rupture of the pump, the steam generator and the lines of the primary loop.
