The device comprises a central body carrying a first inflatable flexible head and two jacks each carrying an inflatable flexible head at its end. The rods of the jacks are oriented in two directions located on either side of the central body to assure displacement of the central body as a result of the retraction and extension of the rods of the jacks in opposite directions. In the expanded state, the inflatable flexible head are maintained by wedging in the annular space between the bundle casing and the outer casing of the steam generator. In the retracted and deflated state, the flexible heads can be displaced in the annular space. The device also comprises an assembly for guidance by rolling on the lower end of the bundle casing of the steam generator.

Movable carrier device for conducting attendance work in the secondary

The device for pressure-sealed obturation comprises a flexible tubular casing (22) having an open end along the perimeter of which the casing constitutes an inflatable toric seal (30) and a base (22a) in the form of a glove finger on which there is fixed the end of a shaft (21) disposed at the central part of the casing (22). The shaft (21) passes through the base (22a) of the casing (22) in a sealed manner. The device also comprises a plate (38) for retaining the casing (22) comprising at least two parts articulated to one another as well as retention plate (41) for fixing the retaining plate (38) under the base (22a). Ring shaped elements (43) are retained against the toric seal (30) by an articulated spacing device (47).
