Abstract

1412764 Nuclear reactor containment NUCLEAR POWER CO (WHETSTONE) Ltd 28 Sept 1973 [28 Sept 1972] 44807/72 Heading G6C A nuclear reactor cooled by a liquid, e.g. sodium, contained in a tank 14 closed by a cover 13 maintained at a temperature lower than that of the coolant 15, embodies thermal insulation 19 extending over an upper, interior part of the tank wall above the coolant 15 and a plurality of separate cooling circuits 20 at different respective axial distances from the upper edge of the tank wall, each circuit 20 being in thermal contact with the tank wall at the respective axial distance and provided with means for circulating through it a coolant maintained at a temperature appropriate to the axial distance, the heat transport capability of each such circuit 20 being large compared with the heat transmission through a corresponding zone of the insulation 19. As shown, each circuit 20 comprises a pair of ducts extending circumferentially of the tank wall in undulating fashion, being welded to spaced contact pads 21 on the tank wall. Each circuit is connected to an individual coolant circulating pump (for circulating a sodiumpotassium coolant which is liquid at room temperatures therethrough) and a heat-exchanger. In an alternative arrangement (not shown) at each axial distance, the circumference of the tank wall is embraced by several separate circuits each comprising a duct or duets extending round a sector, only, of the circumference and connected in parallel in a common circuit or being independent. The undulating form of the ducts allows thermal expansion and contraction movements to occur without stressing the tank wall. The ducts are surrounded by thermal insulation 22; additionally, thermal insulation 18 assists in maintaining the lower temperature in the cover 13. Both the cover 13 and concrete wall 11 of the containment vessel 12 have a steel liner 16A, 16 and embody cooling tubes (not shown). Further, thermal insulation 17 is provided between the liner 16 and wall 11 in the region of the coolant pool 15.
