ABSTRACT:
A nuclear fuel assembly having a bundle of longitudinal fuel elements vertically disposed in a reactor vessel, an upper and a lower tie plate supporting the top and the bottom of the bundle of the fuel elements, a fully ended tubular channel covering around the bundle of the fuel elements to define a coolant flow passage. The channel is removably supported by the upper tie plate. After a predetermined operating period, the channel is pulled out from the fuel assembly, turned upside down and thereafter again inserted over the fuel assembly in a upended state so that the life time of the channel is elongated.
