Abstract
The fuel assembly comprises at least one cluster of canned-fuel pins disposed on a uniform lattice within a sleeve defining a duct through which a coolant is circulated. Each fuel pin is provided at least over the greater part of its length with a helical spacer member which determines the minimum spacing between the fuel pin and the adjacent pins or the sleeve. The internal face of the sleeve is provided with recesses in which the spacer members of the lateral pins of the cluster are partially engaged. The fuel assembly finds an application in nuclear reactors of the liquid-sodium-cooled fast breeder type. This is a continuation, of application Ser. No, 395,454 filed Sept. 10, 1973 now abandoned.
