Abstract
Abstract A fuel assembly for a fast reactor consisting of a bundle of spaced, elongated, stainless-steel-clad fuel pins disposed within a coolant duct contains means for cooling the coolant duct to a lower temperature than that of the bundle of fuel pins and a crushable spacer material disposed in an annulus between the bundle of fuel pins and the coolant duct so that the coolant duct does not swell even though the fuel pins do swell. The crushable spacer material may be extra strength on the side of the fuel assembly closest to the centerline of the reactor core.
