摘要： A method and apparatus for eliminating leakage spaces between the partitions (1) surrounding the core of a pressurized water nuclear reactor, after it is brought into operation. Operations are carried out under water, during shutdown of the reactor. The defective joins (12) between the partitions (1) are identified. For each join, the partitions (1) are pierced, the hole inside a partition (1) is screw-threaded, the swarf is recovered, a screw with diametrical expansion is introduced and screwed into the hole and the screw is expanded by displacement of a rod in the longitudinal direction of the screw. Moving location, the operations are repeated for each defective join (12). The apparatus comprises a case (25) containing a drum (36) bearing tools for boring (54-65), screw-threading, and screwing, a cleaning tube and a punch for locking the screw.

摘要： A vessel such as a nuclear reactor containment vessel is provided with a bottom extension in the form of a cylindrical skirt in which are formed peripheral openings in uniformly spaced relation. A horizontal cross-pin extends through each orifice, projects on each side of the cylindrical skirt and is provided with means for translational locking with respect to the orifice. The threaded upper portion of an anchor-bolt is mounted at each end of the cross-pin while the lower ends of the two bolts are anchored in the foundation raft. The device produces a substantial reduction of stresses in the anchorage zone.

摘要： A nuclear reactor installation includes a pressurized-water coolant reactor vessel and a concrete biological shield surrounding this vessel. The shield forms a space between it and the vessel large enough to permit rapid escape of the pressurized-water coolant therefrom in the event the vessel ruptures. Struts extend radially between the vessel and shield for a distance permitting normal radial thermal movement of the vessel, while containing the vessel in the event it ruptures, the struts being interspaced from each other to permit rapid escape of the pressurized-water coolant from the space between the shield and the vessel.
