ABSTRACT:
A fuel assembly for a boiling water reactor has a fuel channel of generally square cross-section and provided with four walls, which fuel channel surrounds a plurality of fuel rods. Adjacent to its upper edge, the fuel channel is provided with a spacer having a corner portion and two arms extending from the corner portion and making an angle of 90.degree. with each other. The corner portion of the spacer engages a first corner of the fuel channel, and the two arms each make contact with the outer sides of the two fuel channel walls that meet at the first corner. Each arm is provided, at its outermost part, with a diagonally directed, horizontal projection which is inserted into a corresponding aperture in the adjacent fuel channel wall, the two projections thereby bridging across a respective one of the two corners of the fuel channel which are closest to the said first corner. The two projections rest on a lifting plate provided with a lifting handle and are each fixed to the plate by means of a fixing device which is releasable from above.
