Title: Improvements relating to Nuclear Reactor Fuel Elements
Inventor: LINNING DAVID LEES
IPC: G21C3/18
Filed: 1965-12-23
Abstract: 1,174,575. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 22 March, 1967 [23 Dec., 1965], No. 54510/65. Heading G6C. A fuel element for a fast reactor comprises metallic sheathing containing ceramic nuclear fuel possessing in aggregate a density which is less than 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 containing fertile atoms but being depleted in fissile atoms relative to the fuel and having 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 a ceramic compound of plutonium, e.g. (UPu)O 2 , possibly to a slightly non-stoichiometric composition with the uranium at the natural concentration of the 235 isotope and with the plutonium enrichment at a level of about 27%, and the interlayer natural or depleted UO 2 . The fuel may consist of stacked pellets presintered into the requisite density, e.g. 80% of the maximum theoretical density. Alternatively, the pellets are of annular shape in which case 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.

Abstract: 1452958 Silencing gas flow from valves REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 5 Dec 1973 [12 Dec 1972 6 April 1973] 56437/73 Heading B1W [Also in Divisions Fl and F2] A valve assembly, Fig. 1, for regulating the supply of air to an I.C. engine exhaust has inlet and outlet ports 11, 13 connected by a passage from which a by-pass port 22 leads to a silencer 3. A control rod 16 is movable between a first position, as shown, in which a valve member 12 permits flow between the inlet and outlet ports and a valve member 19 closes by-pass port 22 and a second position in which valve member 12 prevents flow from inlet port to outlet port and valve member 19 allows flow from the inlet port 11 through the by-pass port 22. Control rod 16 is movable in response to pressure difference between chambers 4 and 7, chamber 7 being connected to the outlet port of a solenoid valve 25, which also has an inlet port and a venting port 30. Valve member 27 of valve 25 is movable between a normal open position which allows communication between the solenoid valve inlet and outlet ports and a closed position in which the inlet port is closed off and the chamber 7 is vented to atmosphere via port 30. At starting, a choke valve switch 28 energises the solenoid so that reduced pressure from induction manifold 23 acts in chamber 4 and atmospheric pressure acts in chamber 7, resulting in air from pump 9 being allowed to escape via by-pass port 22 and silencer 3. When switch 28 is opened, valve member 27 closes port 30 and chambers 4 and 7 are brought into balance, opening valve 12 and closing valve 19. At intermediate engine speeds, sudden increases in manifold vacuum caused by closing the throttle lead to the pressure in chamber 7 being higher than that in chamber 4 because of the presence of the throttle 26, thus temporarily closing valve 12 and opening valve 19. At high engine speed, when pump 9 produces excess air, its pressure causes valve 19 to open against spring 18. In a modification, Fig. 2, chamber 7 is connected to the inlet manifold 23 via a solenoid valve 25 and a vacuum reservoir 36, the valve 37 of which only opens when the manifold pressure is at least 4.35 psi below the reservoir pressure. The solenoid valve 25 is energised via a switch 28' of a cylinder head thermostat which is closed when the engine temperature is below 15C, or via a temperature detector switch 38 mounted in a catalytic chamber or muffler when the temperature therein is at or above 700C, so that in these circumstances the vacuum reservoir 36 is cut off from the chamber 7 causing valve 12 to be closed and port 22 to be open.

In a rotational moulding apparatus a rotatable mould support shaft is movable into and out of a box-like curing chamber 25, Fig. 1, supported on a framework comprising beams 10, bars 20 and uprights 18, the ends of the chamber being closable by transversely slidable doors 32, Fig. 2. The curing chamber is located between two box-like cooling chambers 50 and the side walls of the three chambers have centrally disposed longitudinally aligned gaps which allow passage of the mould support shafts 106. The shafts 106 are carried by a trolley 70 movable along the beams 10 and each carries a pair of opposed moulds 124, 126, Fig. 4, which are rotated about an axis at right angles to the shaft 106. A rollup screen 56 is operated to open and close each end of the cooling chambers 50. To prevent loss of heat the aligned gaps are closed by displaceable baffles 130, 132 actuated by the reciprocable trolleys 70, the baffles moving down curved guideways 136 to allow loading and unloading. In another example, the baffles are vertically reciprocable in guideways and are actuated by the transversely movable curing chamber doors through a pulley mechanism. In a third example the baffles are pivoted between open and closed positions by the shaft 106 and are retained in their extreme positions by a toggle mechanism or magnetically.
