Title: Fuel element for nuclear reactor
Inventor: GAUTHRON MAURICE
IPC: G21C3/18
Filed: 1963-09-02
Abstract: 969,889. Nuclear fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 2,1963 [Sept. 5, 1962], No. 34629/63. Heading G6C. A nuclear fuel element comprises a sheath 18 housing a fuel rod 16 of fertile or fissile material and closed by a plug 20 welded at 22 to the sheath 18 with an insulating pellet 24, e.g. of alumina, between the rod 16 and the plug 20, the contact surfaces 28 and 30 between the pellet 24 and the plug 20 and between the plug 20 and an abutment member 26 being sufficiently roughened to cause the plug 20 to be subjected to shear stresses when a load is transmitted between the element and the abutment member. In some cases it is preferable to replace the insulating pellet, 24 by a heat conductive pellet. The sheath 18 and the plug 20 may be formed from a Mg-Zr alloy having a very low Zr content. A rough surface is imparted to the pellet 24, which consists of a harder material than the plug 20, and the latter impresses itself on the surface of the pellet 24 during the sheathing under hydrostatic pressure. Grooves are formed in the surface of the member 26 which comes into contact with the plug 20 and penetration and anchoring of the member 26 in the plug 20 take place due to creep under load in the reactor itself during the temperature rise. The shear stresses which result from the roughened surfaces 28 and 30 reduce the tendency of the plug 20 to creep under a given compressive load. As an alternative to the re-entrant plug 20, a plug welded in prolongation of the sheath 18 (Fig. 3, not shown) may be used.

Abstract: 1,170,383. Pipe stoppers. MUELLER CO. 19 July, 1968, No. 34638/68. Heading F2P. A pipeline stopper 10 adapted to be inserted into a transvox aperture in a pipeline comprises an expansible and contractible split sleeve 12 which is provided with a flexible sealing cover 16 extending partly around the periphery of the sleeve and wear strips 31 secured to the sleeve for protecting the cover from the edges of the aperture when the stopper is inserted into or removed from the aperture. The sleeve which is preferably of sheet metal has the wear strips, which are of steel, welded to the sleeve so as to lie parallel to the edges of the split or slot 14 and spaced therefrom. The sealing cover, which may be of rubber, extends partly around the sleeve periphery, preferably about 270 degrees around the circumference, and has longitudinal edges spaced from the wear strips. The sleeve is expanded and contracted by a screw 30 having left-hand and righ-hand threaded portions at opposite ends which respectively mount wedge-shaped collars 40 which themselves engage the sides 20, 22 of substantially triangular-shaped, circumferential spaced, inwardly extending vanes 18 secured to the interior of the sleeve. Fingers 52, 62 secured to the opposite ends of each respective vane ensures contraction takes place when the screw is turned to move the collars apart. In a method of isolating a pipe section to permit the repair or replacement thereof, pipe stopping machines 100, Fig. 4 (not shown) are welded or secured to the pipeline upstream and downstream of the section to be repaired or replaced, said machines being provided with the necessary by-passes, pipe cutters, pipe stoppers and valves and being connected by a by-pass line 102 which is itself provided with a purge line and valves L. A stopper as described above, is inserted into a transverse aperture using the downstream stopping machine with the slot 14 facing downstream, said stopper partially blocking the flow in the pipe line but permitting flow from the by-pass line to enter the pipeline through the slot. The wear strips prevent the cover 16 being torn loose by being forced against the edges of the opening or aperture by the fluid flow pressure as it is entered therein. A similar pipe stopper, which may or may not be provided with the wear strips, is then inserted into a transverse aperture using the upstream stopping machine with its slot 14 facing upstream. Both stoppers are expanded to isolate the pipe section therebetween thus enabling repair or replacement thereof.
