Abstract
1306655 Fuelling reactors COMMISSARIAT A L’ENERGIE ATOMIQUE 7 Oct 1971 [15 Oct 1970] 46618/71 Heading G6C A reactor has two rotatable shield plugs 6 and 8, the inner plug 8 which supports a core cover 10 by means of an axial extension 9 being mounted eccentrically within the outer plug 6 which is disposed in coaxial relation to the reactor core 1. The inner plug 8 has a smaller diameter than the core 1 and the cover 10 which it carries forms above the core a lateral projection with respect to the plug 8, the rotation of this plug about its own axis being intended to expose part of the reactor core as so to permit handling of fuel assemblies within the core by means of an articulated handling arm 20 which is carried by the outer plug 6. The core cover 10 serves as a collector for all the instruments and devices which are intended for measurements or tests to be carried out on the fuel assemblies of the core 1. Control rod guide tubes 12 pass through the shield plugs 6, 8 and are movable downwardly to enter passageways 11 in the core cover 10 when in alignment therewith as in the case of the right hand guide tube 12 in the Figure. The handling arm 20 has articulated link rods 21 for adjusting the position of a grappling system 22, and the operation of this arm 20 in conjunction with the rotation of the shield plug 6 permits the removal of a fuel assembly from any one of the core channels 18 and its transfer to a fuel-handling flask 24 located outside the core blanket 14. The flask 24 is supported by a device 26 movable within a discharge duct 28 secured within the top wall 4 of the reactor shield. The core cover 10 is shown in full outline in its position exposing part of the core 1 and in broken outline in its position for normal reactor operation. The core 1 and blanket 14 are surrounded within the reactor vessel 2 by a neutron shield comprising a lateral wall 30 having a top shield extension constituted by a plate 32, suspended from the outer plug 6 and penetrated by an opening 34 through which the inner plug extension 9 passes, and by a disc 36 contained within the extension 9. The plate 32 is penetrated by a radial passage 38 for the insertion of the handling arm 20 which permits lateral movement of the grappling system 22 towards the core channels 18 or the handling flask 24.
