Abstract
1,217,141. Moderator structures. ENGLISH ELECTRIC CO. Ltd. 5 Feb., 1968 [7 Feb., 1967], No. 5908/67. Heading G6C. In a nuclear reactor concrete pressure vessel, the graphite moderator block assembly is arranged in columns, has a side restraining structure surrounding the assembly and is located within the vessel by keys engaging the vessel side walls. Distortion of the pressure vessel is accompanied by a corresponding distortion of the assembly upper region, by reason of the keys, so that alignment between the standpipes and the core fuel tubes is maintained. Twisting movement of the vessel is transmitted to the core through the keys and the side restraining structure. The core is carried upon a perforated plate which is supported upon the pressure vessel floor by pillars which rock about their lower ends to permit plate radial expansion. Coolant gas is pumped through the core base upwards through the fuel stringers. Gas also passes round the moderator assembly and enters it through the upper surface before passing downwards in the interstitial spaces between the columns. A further flow occurs downwardly in the annular spaces between the fuel stringers and the fuel channel walls. The flow in the core interstitial spaces enters the fuel stringers at the lower ends. Each fuel channel contains a debris collector.
