Title: Resilient moderator structure for nuclear reactors
IPC: G21C5/08
Filed: 1962-05-28
Abstract: 938,529. Moderator structures. UNITED STATES ATOMIC ENERGY COMMISSION. May 28, 1962 [July 11, 1961], No. 20361/62. Class 39 (4). A moderator structure for a nuclear reactor comprises a multiplicity of elongated blocks stacked vertically, at least some and preferably all being under a longitudinal bending stress, and rigid restraining means surrounding the blocks to maintain then in a stressed condition. A single bowed graphite block 1 of hexagonal cross-section is shown in Fig. 4, a multiplicity of these being stacked in layers upon an apertured steel supporting plate 2 (Fig. 1, not shown) and surrounded by a cylindrical steel sleeve 7. Each block 1 is penetrated by a channel 3, the blocks being aligned vertically by means of pilots 4 and recesses 5. In Fig. 2, the structure is shown as being divided into hexagonal regions 8, each of which is occupied by a cluster 9 of blocks 1 such as that shown in Fig. 3. The blocks 1 of each cluster 9 are cemented together using a thermosensitive cement while in a straightened condition, the arrows of Fig. 3 indicating the direction of the convex surfaces of the blocks prior to cementing. Each block 1 is, while in a straightened condition, under tensile stress on its sides which were concave prior to assembly and under compressive stress on its opposite or convex sides, these stresses being identified by letters T and C in Fig. 3. The clusters 9 thus formed are installed in the regions 8 of the structure with the sides of the blocks 1 under maximum compression facing in the direction of the arrows of Fig. 2. The temperature of the structure is then raised to decompose the cement, the individual blocks 1 thus being freed to exert a lateral force on laterally contiguous blocks. Consequently, a lateral load which is ultimately borne by the peripheral sleeve 7 is imposed on the structure. To prolong the life of the graphite blocks in the peripheral regions of the structure, the blocks in the peripheral clusters A are stressed to a greater degree than those in the inner regions since the fast neutron flux gradient, which causes shrinkage of graphite at high temperatures, is greatest in the peripheral regions. Since the structure is in a stressed condition during reactor operation, differential dimensional changes due, for example, to the steel structure (i.e. plate 2 and sleeve 7) expanding more in response to an increase in temperature than the graphite, or to exposure to radiation, will be - automatically accommodated. The invention is not limited to moderator blocks of hexagonal cross-section, blocks of octagonal, circular and square crosssections being equally suitable. Specification 931,972 is referred to.

As shown a waveguide 11 connects the magnetron 12 to chamber H but in Fig. 7 (not shown) the antenna of the magnetron 12 projects directly into the chamber H through wall 10. As shown, the mode stirrer means comprises two mode stirrers 14b, 14c arranged symmetrically on opposite sides of the central axis behind a protective low permittivity partition 17, but it may comprise more than two mode stirrers symmetrically arranged, or one mode stirrer arranged symmetrically relative to the axis. The underside of upper section 6a of the frame 6 reflects microwave energy from the waveguide 11 to the mode stirrers 14b, 14c. Air from blowers 16 is circulated through the chamber H via entry openings 18 and exit openings O in the side walls 4c of the casing 1. Conventional timers, start switches, safety interlocks and microwave door seals are provided. Each mode stirrer may comprise conductive blades b caulked to a conductive hub h (Fig. 8) which is arranged to rotate on a conductive shaft 15. The shaft is secured in a low permittivity pedestal P1, mounted on wall 10. The hub h is fixed to a low permittivity spacer m by a securing ring and the spacer m rotates on the shaft. The coaxial arrangement of the hub h and shaft 15 prevents the concentration of electric field at the end of the shaft and hence spark discharge from the ends of the shaft 15 and heat deformation of spacer m can be eliminated.

Abstract: An aminonitrile of formula <FORM:0674246/IV (b)/1> where R is an aryl thienyl pyridyl or furyl group, Y is an alkylene bridge of 2-3 carbon atoms, -N=B is an aliphatic tertiary amino group, and R1 is cyclopentenyl or cyclohexenyl is prepared by treatment of <FORM:0674246/IV (b)/2> <FORM:0674246/IV (b)/3> where A is cyclopentylidene or cyclohexylidene with the compound Halogen-Y-N=B in the presence of a strong base.  The resultant aminonitrile may be heated with a suspension of sodamide in an inert solvent to give an amine <FORM:0674246/IV (b)/4> where the unsatisfied valencies of the carbon atom adjacent to the group R are satisfied by a cyclohexylidene group, a cyclopentylidene group, a cyclohexenyl group and hydrogen, or a cyclopentenyl group and hydrogen (the two different types of compound being tautomeric).  The group -N=B may be dialkylamino or a cyclic amino group, e.g. morpholinyl, piperidinyl or pyrrolidinyl.  Salts may be formed of the aminonitriles and the amines with acids or lower alkyl esters of strong inorganic or organic sulphonic acids.  The group R, when aromatic, may be phenyl, anisyl, tolyl, or naphthyl.  The nitriles <FORM:0674246/IV (b)/5> <FORM:0674246/IV (b)/6> (tautomeric forms, both being present to some extent) may be prepared by treatment of a mono-substituted acetonitrile with cyclopentanone or cyclohexanone, or with a D 2- or D 3-cyclopentenyl or cyclohexenyl halide, the latter method giving only compounds of formula  <FORM:0674246/IV (b)/7> In the examples, (1) cyclohexanone is condensed with benzyl cyanide to give cyclohexylidenephenylacetonitrile, which is treated with piperidinylethyl chloride to give (p-piperidinoethyl)-D 1 - cyclohexenylphenylacetonitrile, which heated in xylene with sodamide affords 1-piperidino - 3 - phenyl - 3 - (D 1 - cyclohexenyl)-propane; (2) cyclopentanone is condensed with benzyl cyanide to give cyclopentylidenephenylacetonitrile, treatment of which with piperidinoethyl chloride gives b -piperidinoethyl-D 1-cyclopentenylphenylacetonitrile, treatment of which as above affords 1-piperidino-3-phenyl-3-(D 1-cyclopentenyl) propane.  Many other examples (13) are given.

Abstract: 1304073 Lubricating oils SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 30 April 1970 [2 May 1969] 20931/70 Heading C5E [Also in Divisions B1 and G3] In a process for preparing a lubricating oil by catalytic hydrogen treatment followed by at least one physical separation step the viscosity index is controlled by measuring a physical property of the process stream, after the hydrogen treatment but before the last physical separation step, which property correlates with the viscosity index of the finished lubricating oil, comparing this measured value with a predetermined set value and adjusting one or more process conditions of the hydrogen treatment so that the difference between the measured and set values is reduced. The physical property measured is suitably the refractive index, using a continuous or differential refractometer, or density after the process stream has been degassed. The hydrogen treatment can be carried out in two stages with the physical property being measured between the first, more severe stage, i.e. hydrocracking or hydrotreating, and the second, milder stage, e.g. hydrofinishing. The property can be measured intermittently or continuously by hand or automatically, the signal corresponding to the measurement being supplied to a controller which operates a correcting unit pneumatically, electrically, electronically, mechanically or hydraulically. The correcting unit alters the process conditions, e.g. the reaction temperature by regulating the amount of fuel used to heat the reactor or the amount of hydrogen injected for interstage cooling of the reactor, the pressure in the reactor or the space velocity by regulating the feed supply. The physical separation step which follows the measurement of the property can be an atmospheric and/or vacuum distillation or a solvent dewaxing. A first meter, connected to a first controller, can be provided in the supply line from the hydrogenation zone to a distillation column from which the bottoms is passed to a dewaxing unit and a second meter can be provided in the discharge line from the dewaxing unit; the measured property of the dewaxed oil being compared with a set value in a second controller which then establishes the set value for the first controller. The lubricating oils produced can be distillate or residual fractions. The hydrogenation catalysts used in the examples comprise Co and Mo on alumina containing 6À5 wt. per cent F or on silica-alumina, Ni and W on alumina containing 6À5 wt. per cent F and Ni and W on alumina; these catalysts are sulphided using H 2 S in hydrogen before use.
