Patent ES-331324-A1 (ES)
Title: Nuclear reactor fuel element
IPC: G21C3/04
Filed: 1966-09-17
Abstract: A superheater fuel element comprises a tubular member 32 secured at each end to a tube sheet 10, 12, between which sheets extends a plurality of tubes 14, 16 penetrating fuel pellets 26. The pellets 26 are retained in position by means of springs 28 which are compressed between the tube sheet 10 and washers 30. A body of stainless steel wool 29 interposed between a pair of washers 27 separates each stack of pellets 26 from the tube sheet 12. The fuel element is employed in a boiling water reactor, the water being in engagement with the tubular member 32 and the steam produced being directed first through the tubes 16 in the direction indicated by arrows 22 and then by a deflector 20 through the tubes 14 emerging from these tubes in the direction indicated by arrow 24. The tubular member 32 has a flexible section 31 which permits relatively free axial movement between the interconnected tube sheets 10, 12. In order to reduce the stresses developed in the tubes 14, 16 due to the differential thermal expansion of these tubes in operation, the fuel element is manufactured in a prestressed condition. The tubes 14, 16 and the tubular member 32 are all made of a suitable Ni-Cr alloy. In assembling the element the tubular member 32 and the first pass tubes 16 are welded to the tube sheets 10, 12. The second pass tubes 14 which are somewhat shorter than the tubes 16 are welded to one of the tube sheets and then the element is compressed until the end of the tubes 14 are flush with the other tube sheet, these tubes then being welded to this tube sheet. This provides a prestressing such that at room temperature the tubes 14 have a tensile stress and the tubes 16 have a compressive stress. In a modification in which the tubular member 32 has no flexible section 31, the tubes 14 are somewhat shorter than the tubes 16 which are in turn shorter than the tubular member 32 and a similar method of assembly results in the tubes 14 having at room temperature a considerable tensile stress, the tubes 16 a much less tensile stress and the tubular member 32 a compressive stress.
