Title: Fuel assembly for a nuclear reactor
IPC: G21C3/332
Filed: 1970-03-17
Abstract: 1,267,615. Fuel elements. WESTINGHOUSE ELECTRIC CORP. 17 March, 1970 [29 April, 1969], No. 12679/70. Heading G6C. A fuel assembly comprises a plurality of elongate fuel elements surrounded by a thinwalled enclosure formed from stainless steel or a Zr-base alloy, and a plurality of support grids positioned within the enclosure and consisting of an Ni-base alloy or an Fe-base alloy having good spring characteristics even under nuclear irradiation to maintain the fuelelements in a fixed spaced relationship but allowing for longitudinal movement of the fuelelements resulting from thermal expansion, the fuel support grids being mounted within the enclosure by support means extending in axial direction of the fuel assembly and being held in spaced relationship from the support means by resilient mounting tabs extending from the grid sections adjacent said support means and engaging the enclosure thereby permitting expansion of the grid relative to the enclosure. The support means and the enclosure may be one- and the same, in which case the mounting tabs extend outwardly fromthe periphery of the grid and engage theenclosure. In the embodiment shown in Fig. 2 a grid 19 made up of a plurality of thin bands of an Ni-base alloy or stainless steel arranged in a lattice configuration has mounting tabs 27 located at intervals around the outer periphery of the lattice. In attaching the grid 19 to an enclosure 11 of a Zr-base alloy, flanged weld buttons 30 of a Zr-base alloy are inserted through holes 29 in the tabs 27 and spot welded to the enclosure. The flanged portion of the weld buttons 30 holds the tabs in a fixed relationship with the enclosure 11. The fuel elements inserted through the grid are provided with a thin cladding of a Zr-base alloy. The tabs 27 are curved to provide an offset 31 to allow the grid 19 to expand laterally relative to the enclosure 11. Because the enclosure and fuel cladding are both formed from a Zr-base alloy, thermal expansion will not cause buckling since both will expand at the same rate under varying temperature conditions. In an alternative embodiment (Fig. 4, not shown), the tabs are held by mounting straps periodically spot welded to the enclosure. Axial expansion of the grid is permitted since the tabs are free to move within raised portions of the straps. A plurality of such fuel assemblies are used within a nuclear reactor with cruciform-shaped control rods (Fig. 5, not shown) housed between the fuel assemblies. These control rods consist of a plurality of elongate members of a suitable neutron-absorbing material, e.g. hafnium. Bars of a Zr-base alloy aresecured to the enclosure, e.g. by spot welding, near both the ends and the centres of the control rods for reducing flux packing and increasing the rigidity of the enclosure.

Abstract: 746,648. Soldering and brazing. GENERAL MOTORS CORPORATION. May 5, 1954 [May 27, 1953], No. 13039/54. Class 83 (4). In a method of brazing titanium or its alloys a nickel-containing layer is placed between the surfaces to be joined and the parts are heated to diffuse the nickel into the titanium. A pair of titanium members 10, 12, Fig. 1, are joined by titanium sheets 14, 16 brazed thereto with intermediate nickel shims 18-24. The titanium parts are first cleaned with dilute hydrofluoric acid and after assembly are heated to 1850‹ F. for 45 minutes in an inert gas atmosphere of helium or argon until the nickel is absorbed into the titanium. The assembly is then cooled in the inert atmosphere and may be finally hardened by reheating to 1400-1800‹ F. and quenching in water followed by a final tempering at 400-1400‹ F. In modifications, nickel or its alloys may be applied to the surfaces by a metal spray gun or a metal powder having a nickel content of 13-38 per cent, such as a nickel-titanium alloy may be applied, preferably mixed with a volatile lacquer.

Abstract: 453,791. Thermally-controlled valves. LUNDBERG, K. E., 3A, Stjõrnhjelmsgatan, Upsala, Sweden. May 3, 1935, No. 13208. [Class 135] In a thermostatically-controlled device for regulating the supply of gas or fluid, e.g. oil for combustion in a furnace, of the type comprising a byepass valve and a controlled main valve, the main valve is carried by a pivoted lever actuated by a second pivoted lever, the latter being caused to follow the movements of the thermostat. A needle valve 82 controls the byepass 83 entering the passageway 80 at the inner end of which is situated the main valve 104. The operating- rod 89 of the thermostat contacts with a rod 86 fixed to a socket-member 87<A> having a threaded engagement with an outer socketmember 94 pressed downwardly by a spring 90 so as to keep the rods 86, 89 in contact. A sleeve 91 fixed to the member 94 rests on a knife edge 100 on a lever 98 pivoted at 99 and having a pin 103 engaging an arm 102 of a spring-controlled bell-crank lever carrying the main valve 104. Movement of the thermostat rod 89 causes movement of the rod 86 so as to operate the levers 98, 102 and thus opens or closes the valve 104. An adjusting knob 87 and a graduated disc 88 on the members 87<A>, 94 respectively are provided so that by relative rotation of the members 87A, 94, the main valve 104 can be set relatively to the rod 89 according to the range of temperature required over which the control is to operate. Bellows connections 92, 95 between the sleeve 91 and the socket 94 and thermostat respectively prevent the fluid from coming into contact with the rod 86. Complete closing of the valve 104 may be prevented in order that a certain minimum of fluid may be supplied, by means of an adjustable stop 105 adapted to engage the end of the lever 98 in its extreme position.
