Abstract
1367451 Nuclear reactors BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd 27 Sept 1971 [29 July 1970] 36805/70 Heading G6C In a sodium-cooled nuclear reactor, the core and heat exchangers are mounted together within a prestressed concrete pressure vessel and the core is offset from the vessel centre to effect an efficient use of the internal space. The asymmetrical, thermally generated stresses in the coolant system pipework are resisted by the core support structure. The core 16 and the heat exchangers, 20, are connected by the ducts 26, 28 and mounted in the concrete pressure vessel, 10. The core and heat exchangers are anchored to the beams, 50, which, with the base part 18<SP>1</SP> of the shield 18, constitutes a supporting base structure. The top cover, 19, is designed to fail progressively during high, transient pressures in the core. The mixers, 30, ensure that coolant leaving a faulty secondary coolant circuit, 34, is cooled by sodium from the remaining exchangers. The liner, 12, has a heat resistant covering, 40, and a thermally conductive covering, 42. The tubes 44 carry cooling air. Thermal stresses in the liner 12 at the level of the cold pool 24 are reduced by minimizing variations in this level; to this end, the cold pool has a surface area large compared with that of the hot pool 36. In another embodiment (Figs. 5 and 6, not shown), the level of the cold pool is controlled and maintained constant by employing variable differential pressure in an inert gas above the hot and cold pools (which are separated by extending the hot pool dam (36) to the roof of the pressure vessel). The pressure in volume (38) is adjusted by pump means controlled by sensing means.
