The stabilization strut comprises at least two coaxial tubular elements (respectively an upper element and a lower element) which are telescopically assembled together, together with an extension system for moving the lower element axially towards or away from the upper element. The upper element is pivotally mounted about a pin carried by the structure, and pivoting movement of the strut is controlled by a pivot system hinged to the structure about a pin and actuated by the extension system for the strut. The invention is applicable to stabilizing equipment shelters, for example.

Stud bolts are threaded into the body of a nuclear reactor vessel and tenned by exerting forces on tensioning nuts located on the upper end of the studs. While the studs are under tension, a cover is attached to the vessel by tightening nuts on the studs against the cover. The tensioning nuts are applied to the studs by immobilizing the studs axially and rotationally, and rotating the tensioning nuts with a pair of driven, diametrically opposed striking rollers. External threads on the striking rollers, external threads on the nut and internal threads on the nut all have the same pitch so that the threads on the striking roller remain engaged with the external threads on the nut as the nut moves axially while being threaded onto the immobilized stud.
