  • Liquid-cooled nuclear reactor especially a boiling-water reactor
    Patent number: 4789518
    Abstract: Liquid-cooled nuclear reactor having a reactor pressure vessel and a reactor core of fuel assemblies received therein, the fuel assemblies being grouped into core cells each having a control rod containing absorber material and connected to a drive mechanism, including a sheetmetal shaft associated with the core cells, respectively, and extending beyond the length of the reactor core by a length at least equal to that of the respective control rod and having a cross section substantially equal to that of the respective core cell, the sheetmetal shaft being formed with longitudinal channels through which the fuel assemblies are loadable and unloadable.

  • Pressure tank for nuclear reactors with concrete enclosure
    Patent number: 4035974
    Abstract: A pressure tank construction for nuclear reactors includes a steel tank which is inserted into a concrete enclosure. A clearance is provided between the steel tank and concrete enclosure when the steel tank is unpressurized and at ambient temperature. Under operating conditions, the steel tank expands and bears against the concrete enclosure. A support and insulatory means is also provided between the steel tank and the concrete enclosure.

  • Nuclear reactor pressure vessel for nuclear reactors with plastically deformable spacers
    Patent number: 4011132
    Abstract: Cylindrical pressure vessel structure for nuclear reactors comprises a steel pressure vessel adapted to receive therein a pressurizing medium, a concrete enclosure at least partly producible in situ, the steel pressure vessel being mounted within the concrete enclosure and, in unheated and unpressurized condition, being radially and axially spaced from the concrete enclosure, and a supporting and insulating layer secured in the radially extending space between the steel pressure vessel and the concrete enclosure, the steel pressure vessel, during operating condition thereof wherein the steel pressure vessel is heated and pressurized, being expansible so as to bear through the supporting and insulating layer against the concrete enclosure, the supporting and insulating layer having support plates on the side thereof adjacent the steel pressure vessel, spacer members connected with the support plates and projecting beyond the surface of the support plates in direction toward the steel pressure vessel, the space
