[Also in Division H1] A cell adapted for electricity generation thermionically from the heat of neutronirradiated nuclear fuel, comprises a pair of thermionic conversion elements comprising respective cathodes on respective sides of a charge of nuclear fuel and in heat exchange relationship therewith, and respective anodes being adapted to be fluid cooled and arranged for receiving thermionically emitted electrons from respective cathodes across respective interelectrode spaces. In the cell shown in Fig. 3 the anodes 52 and cathodes 54 are in the form of circular laminµ. Each anode is connected through an annular insulator 58 to a ring 60 secured to the edges of a circular aperture formed in a square plate 70. Each cathode 54 is joined to a flexible cathode membrane 62 which may be of tantalum and which is joined to the ring 60 to form an electrical connection and a seal for the discharge space. The anodes may be of zircalloy and the cathodes of molybdenum with a molybdenum-tungsten sponge surface emitter coating. The fuel 68 may, as shown, be inserted between the two cathodes in the form of a flat wafer, or it may be flame sprayed on to the cathode surfaces. The cathodes may or may not be held together by welding or by other means. If the joint is not sealed, or if the joint leaks, fission gases may escape into the space 76 but will still be confined. As shown in Fig. 6, a plurality of cells 48 may extend between four vertically elongated side plates 82 to form a fuel assembly. The plates 82 are joined together at their upper and lower ends by upper and lower end adaptors (not shown in Fig. 6, which is a plan view) and are provided with longitudinally extending spacer blocks 85 which may also serve for making electrical connections to the anodes of the cells-; connection to the cathodes may be provided in the grooves 86 separating the blocks, insulation being provided in the grooves and between the blocks 85 and the plates 82. The plates 82 are provided with vertically extending passages 84 into which neutronabsorbing balls may be dropped for control purposes. A plurality of fuel assemblies may be joined together by bolting together their upper and lower end adaptors to form the fuel core of a reactor, which may be of the boiling water or pressurized water type producing a thermal output through the usual heat exchanger as well as the electrical output from the thermionic conversion. Specifications 894,902 and 981,565 are referred to.
