Abstract
1505577 Reactors WESTINGHOUSE ELECTRIC CORP 3 Sept 1975 [4 Sept 1974] 36209/75 Heading G6C A reactor, particularly of the sodium-cooled fast-breeder type, has, as part of the lower internals, a massive supporting structure 191 for supporting the core assemblies 121. The structure 191 carries the weight of the core assemblies 121 and their components and serves to distribute the heat-exchange fluid to the core and the other parts of the reactor vessel 21; it also transmits the forces of the weight which it supports, of the hydrostatic pressure of the fluid and of any seismic loads to the reactor vessel 21. The structure 191 has a massive plate 193 in which inlet modules 221, 223 which support, and distribute fluid to, the core assemblies 121 are removably mounted in openings 195. Each opening 195 has a liner 203 open at the top to receive a corresponding module 221, 223, and closed at the bottom to provide a low pressure plenum below the module and thus balance the hydrostatic forces of the fluid on the module so that the module is not ejected from the plate. The liner 203 is held mechanically in the plate 193 between a shoulder 300 engaging the bottom of the plate 193 and a collar 207 engaging the top of the plate. The collar 207 is welded to the liner 203 by a circumferential weld 228 which on solidifying pre-tensions the portion of the liner 203 between the collar 207 and the shoulder 300 and prevents the collar 207 from becoming loose on the liner 203 as the result of thermal transients. The opening 195 in the plate 193 in which each liner 203 is inserted is counterbored to provide an annular space between the plate and the liner in which heat-transfer fluid entering and leaving through holes 197 in the wall of the counterbore can flow around the liner. The massive plate may be formed in two parts: a massive inner disc and a massive ring secured to the plate by webs which take up the shear stress between the disc and the ring produced by the loads on them (Figs. 6A-6C, not shown).
