Claims3
The combination comprising a generally cylindrical nuclear reactor pressure vessel having a longitudinal axis, a plurality of radially projecting lugs attached to and spaced circumferentially about said pressure vessel, a support foundation, a plurality of base plates attached to said foundation, and a plurality of links disposed parallel to the longitudinal axis and a plurality of pins disposed laterally to the longitudinal axis, said links and pins being arranged at circumferentially spaced intervals so that one of said pins pivotably connects one end of a link to one of said lugs and another of said pins pivotably connects said link at its other end to a base plate forming link and pin supporting arrangements at circumferentially spaced intervals such that the pressure vessel is longitudinally supported and restrained from longitudinal, lateral and rotary movement by said link and pin supporting arrangements.
