Title: Improvements relating to Nuclear Reactor Fuel Elements
Inventor: ELLINGTON JOHN PETER
IPC: G21C3/20
Filed: 1965-12-30
Abstract: 1,170,062. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 30 March, 1967 [30 Dec., 1965; 23 June, 1966], Nos. 55235/65 and 28202/66. Heading G6C. A fuel element for a fast reactor comprises metallic sheathing containing ceramic nuclear fuel possessing in aggregate a density which is at most 85% of the maximum theoretical density so as to include distributed voidage, and a solid interlayer disposed between and directly contacting both the sheathing and the fuel, the interlayer being of a material which does not contain fissile or fertile atoms and which has thermal insulating properties. The interlayer serves to increase the operating temperature of the fuel and hence lower its compressive creep resistance, thus enabling absorption in the voidage of irradiation-induced swelling of the fuel. The fuel may comprise (UPu)O 2  or consist of a core of natural or depleted UO 2  surrounded by a zone of PuO 2 . Suitable interlayer materials are ZrO 2 , Al 2 O 3 , BeO, and pyrolytic carbon with its minimum conductivity direction perpendicular to the fuel surface. The fuel may consist of stacked pellets. If the pellets are of annular shape, the central hole contributes to the requisite voidage and pellets of greater density can then be used. A number of the fuel elements are arranged in parallel array on a triangular lattice between top and bottom support plates within a casing having a bottom fitting with spaced cylindrical bearing surfaces for fitting into a socket of a reactor core support structure so that the assembly is supported in cantilever fashion. When positioned in the core each assembly is separated from its neighbours only by narrow gaps which are predetermined by the pitch of the sockets and by corner abutments or pads projecting from the casing. Alternatively, the fuel element may be of the " tube-in-shell " type with the sheathing comprising an external wall in the form of a metal shell with a layer of solid non- fissile thermal insulating material forming the inner face and a number of metal coolant tubes within the shell, ceramic fuel being disposed inside the shell in the space between the tubes and the inner face of the layer of insulating material.

Abstract: 646,835. Conveyers. ARMSTRONG, N. F., and TWEDDELL, J. A. Nov. 1, 1948, No. 28241. [Class 78 (i)] A device for controlling the passage of a series of articles along a conveyer 2 comprises a two-way micro-switch 8 connected to a tripper, a cam 1a connected to an arm 1 pivotally connected to links 3, 4, 5, the tripper being actuated by the passage of the articles on the conveyer. Condenser 9, 10, 11 are adapted in one position of the switch to be charged and in the other position to control a solenoid 6 which when energized causes' the tripper 1a to be moved into the path of the moving articles and held there, and so arrests their progress until the condensers have finished discharging when the solenoid is again deenergized and the arresting means rendered inoperative and the cycle repeated for the next article. Condensers 9, 10 have switches 14 and 15 to eliminate one or both to vary the length of time of discharge and therefore vary the spacing of articles. In the other normal position of the micro-switch the D.C. terminals of a rectifier 16 are connected across the condensers to charge. The tripper also operates a micro-switch 21 in circuit with a condenser 20 energizing a solenoid 19 and controlling a solenoid circuit of a detent 22 engaging a recess 23a in a wheel 23 connecting by a rod 24 to a label spreader driven through a motor 25. A sheaf-spring 18 normally presses against the sides of the bottles. For positioning as well as spacing, the switch 13 controls a solenoid operating two V-blocks which grip the article on the conveyer.
