<p>1. Retractable cable carrier, situated beneath the shielding (9) of a nuclear reactor, to support the cables supplying the actuating mechanisms (5) of the control rods and the position indicators disposed above the cover (4) of the vessel (3) of the nuclear reactor and protected by an anti-seismic ring (6), between the cover (4) of the vessel (3) of the reactor and an attachment post (40) fixed to the wall (1) of the containment (2) of the reactor ; each cable (15) having two connections (16, 17) : a first connection which connects the cable to an actuating mechanism or to a position indicator, this connection being referred to hereinbelow as a "vessel side" connection (17) and a second connection which connects the cable to an energy source, this connection being referred to hereinbelow as a "supply side" connection (16), characterized in that a retractable device (24), mounted on the anti-seismic ring (6) composed of two chains (29, 30) made solid with one another and each formed of two articulated, parallel bands connected to one another by struts (57) serving for the retention and for the guidance of the cables, being partially or wholly supported, in the folded-back position, on rails (26, 27, 28) made solid with the anti-seismic ring (6), supports the said cables between the cover (4) of the vessel (3) of the nuclear reactor and the said attachment post (40) in the unfolded position and is drawn into a jig permitting special toolings to have easy access to the cover (4) of the vessel (3), in the folded-back position.</p> |
