Abstract

1,132,091. Moderator structures. ENGLISH ELECTRIC CO. Ltd. 9 June, 1966 [11 June, 1965], No. 24794/65. Heading G6C. In a nuclear reactor, the graphite moderator is mounted within a prestressed, cylindrical, concrete pressure vessel. To prevent misalignment of the fuel element channels in the moderator, and the standpipes in the vessel, due to dimension changes in the concrete, each vertical column of graphite blocks in the moderator is supported on a pedestal rigidly secured in the concrete. Each channel contains a graphite tube which holds the fuel and which is supported on a mounting within the pedestal. The base of each pedestal may be cooled by the pressure vessel cooling system. Spaces between the columns are provided to permit Wigher growth, graphite reflector blocks surround the core and radial restraint bars are mounted circumferentially between the moderator and concrete. Thermally induced dimension changes in the fuel channel tubing are accommodated by flexible bellows. The coolant gas may perform either a single or double pass along the channels.
