ABSTRACT:
A pressure vessel, containment or burst shield for a nuclear reactor has a substantially circular cover surmounting the cylindrical part (shell) of the vessel and preferably comprised of a plurality of circular segments arranged concentrically and stressed inwardly by annular prestressing means. At least the outer segments and preferably all of the segments are provided on the upper surface with upwardly open circular grooves receiving the prestressing arrangement. The latter can comprise an outwardly open channel-shaped (U-section) supporting member receiving the stressing cables and means for transferring the radial stress of the annular stressing arrangement to the ring segment. The latter means may be wedges inserted between the support and a wall of the groove after the stressing arrangement has been placed under stress, e.g. by hydraulic means for spreading the annular stressing arrangement.
