<p>1,207,217. Reactor pressure vessels. COMMISSARIAT A L'ENERGIE ATOMIQUE. 26 June, 1968 [3 July, 1967], No. 30375/68. Heading G6C. The nuclear reactor concrete pressure vessel 10 has an enclosure formed of the slab 26 and wedges 28 which bear on the conical faces 18 and 24 respectively. The hydraulic jacks 29 urge the wedges 29 against the face 24 together with the jacks 38 which are supported on the carrier 20. The jacks 40 urge the slab 26 against the surface 18. Longitudinal and circumferencial stressing cables 12 and 14 are mounted within the wall structure. The control rods 70 slide within the ducts 71. Leak-proof and thermal insulation linings cover the wall wall surfaces of compartment 16. To prevent damage by overpressure in the reactor core compartment 16, the safety system 62 controls valves 64, 66 in the hydraulic supply line to the jacks. In a second embodiment, the surface 24 is flared outwards and the wedges are maintained in position by cables stretched between the vessel outer face and the wedges.</p> |
