Abstract

1,132,961. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 14 Feb., 1966 [13 Nov., 1964], No. 46390/64. Heading G6C. A sodium cooled fast reactor has a core support structure disposed in a vessel (not shown), this structure defining a closed cylindrical chamber into which the coolant enters through ports 10 (Fig. 2, not shown) in its bottom wall. The upper wall of the structure is perforated with apertures divided into two groups, a central group for coupling to core assemblies 28 and an outer annular group for coupling to shield elements 24, 29. The central group also includes control rod assemblies 13. Each core assembly 28 comprises a hexagonal casing forming a coolant flow path for fuel disposed therein, the assembly having a stem 16 and a plug 15 whereby it is supported by a cup 14 in a coolant pipe 18. The control rod assembly 13 also comprises a hexagonal casing providing a coolant flow path for a control rod disposed therein, this casing being in fluid flow connection with a further pipe 18. All the pipes 18 extending downwardly from the central group of apertures are connected through horizontal radial extensions 19 to further vertical pipes 18 extending to apertures of the outer annular group. Those pipes 18 of the outer group supporting the shield elements 24 by means of a cup 14 receiving a plug 15 on a stem 16 of the element, have coolant inlet parts 26, the flow of coolant through the pipe being regulated by vanes on the stem 16 co-operating with slots in a valve casing 25. Thus by rotating the elements 24 the coolant flow through the assemblies 13, 28 may be regulated. The individual valves may be grouped together for operating by a single actuator (Figs. 3-6, not shown).
