    摘要: An improved pressurized water-cooled reactor system which includes a reactor core pressure vessel; coolant lines coupled to the pressure vessel; vertically arranged steam generators having the housings thereof coupled to the coolant lines; and coolant pumps associated with the steam generators and coupled to the coolant lines. Each of the pumps has a vertically arranged impeller portion driven by an electric motor for circulating coolant between the pressure vessel and tube sheet type heat exchangers in the steam generators, at least the impeller portion of each pump being disposed within a chamber associated with each steam generator which is communicative with the coolant lines. The vessel, the coolant lines and the steam generators including the impeller chamber are each individually encapsulated by rupture-proof safety housings (encasements) forming a protection system for the primary loop components.

    摘要: A pressurized-water coolant reactor installation includes a reactor pressure vessel, a steam generator containing a heat exchanger through which coolant from the vessel is circulated, and a single pipe interconnecting the vessel and generator and internally divided into two conduits for conducting the coolant to the steam generator and from the latter back to the vessel. This single pipe is divided into these two conduits by a partition wall extending longitudinally for the length of the pipe inside of the pipe. This horizontal partition is formed by at least two sections extending radially from the inside of the coolant pipe towards each other and having inner edges spaced from each other and interconnected by an expansion joint.

    摘要: A nuclear reactor pressure vessel is vertically positioned in a concrete reactor pit. The vessel thermally expands and contracts axially and radially. To reduce the possibility of a wall rupture caused by the radial expansion, the top and bottom of the vessel are restrained from movement by the axial expansion, thus placing the vessel's wall under compressive stress in the axial direction. At the top this is done in any prior art manner. At the bottom, the restraint is provided by a series of vertical leaf springs circumferentially interspaced around the vessel's bottom, the lower ends of the springs being fixed to the vessel and the springs extending upwardly therefrom to upper support arrangements. Thus, the bottom of the vessel is suspended by the springs working in tension, while the radial expansion and contraction movements are accommodated by flexure of the springs.
