Title: Thermionic nuclear reactor
IPC: H01J45/00
Filed: 1965-02-08
Abstract: 1,037,250. Reactors; fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. Feb. 8, 1965 [Feb. 25, 1964], No. 5295/65. Heading G6C. A reactor in which fission heat is converted directly into electrical energy comprises a plurality of elongate thermionic fuel elements retained by a support structure to define a cylindrical core enclosed in a sealed cylindrical vessel; liquid metal coolant is circulated through the core to cool the fuel element outer surfaces, and a number of neutron reflecting members are movable around the core exterior to effect control of the reactor. Each fuel element contains a plurality of series-connected thermionic converters, and some of the fuel elements are emitter earthed whereas others are collector earthed, thus doubling the voltage available from an individual fuel element. The overall plant efficiency can be increased by utilizing the surplus heat in a conventional generating system. The reactor utilizes liquid sodium coolant, and the thermionic connectors are supplied with caesium vapour. The reactor comprises a core 75 of emitter and collector earthed fuel elements 101, 102, each having connected to it, by pipes 14, an individual caesium reservoir 15. The core 75 is mounted in a housing 18 comprising upper and lower coolant manifolds 25, 26, coolant distributer 27, a fixed reflector 19 and outlet and inlet coolant conduits 30, 31 respectively. The coolant is liquid metal. Scallops 21 in the reflector receive rotatable control reflector shoes 87. The upper vessel head 50 (Figs. 3 and 4, not shown) comprise two superimposed layers of I beams, each having its flanges lying in horizontal planes and one being laid with its beam longitudinal axes at right angles to those of the other layer. The caesium vapour supply tubes pass through holes drilled through the flanges and the full depth of the webs. Fuel elements (Fig. 5, not shown) comprise a plurality of connector cells 200 axially arranged in an elongate niobium can 150. Neutron reflecting portions 133, 143 are provided at each end, the upper one being penetrated axially by the caesium vapour conduit 14 and the lower one by the electrical output lead 103 or 104. The output leads from the emitter earthed fuel elements are of different extension length beyond the fuel element lower end compared with the collector earthed elements, to facilitate making the bus-bar connections. Each converter cell (Fig. 10, not shown) comprises a pellet 202 of uranium dioxide or uranium carbide housed in an emitter container 201 of tungsten, rhenium, or niobium. The collector 203 is spaced from the emitter, and may be of molybdenum, however, since caesium vapour in the space 204 between the emitter and collector tends to deposit on the collector, any high-temperature material, such as tantalum or niobium, can be used for the collector. The series electrical connections between adjacent converter cells are made by pins passing through insulating discs.

Title: Process and Apparatus for the Combustion and Evaporation of Radioactive Residues.
Inventor: AMAVIS RENE
IPC: G21F9/14
Filed: 1967-02-07
Abstract: 1,163,099. Processing radio-active waste. EUROPEAN ATOMIC ENERGY COMMUNITY. 17 Feb., 1967 [18 Feb., 1966], No. 5733/67. Heading G6R. In a process for the combustion and evaporation of radioactive residues, heat released by combustion of radio-active residues is employed to evaporate other, liquid radio-active residues. An apparatus for use with this process comprises a burner 3 fed with liquid highboiler residues by a pump 2 from a tank 1 and with air from a blower 12. Preheating of the burner 3 is effected by means of heavy fuel oil fed into the burner 3 by a pump 7 from a tank 6. The burner 3 penetrates by means of an extension tube 14 into a postcombustion chamber 15 in which combustion initiated in the burner 3 is completed. The burner 3 preferably operates at a temperature of at least 1100‹ C. and the chamber 15 at a temperature of at least 900‹ C. During the preheating of the burner 3, the combustion gases from the chamber 15 are directed by a valve 17 into a heat exchanger 19 fed at the upper end by air from the blower 12. The heated air leaves at the lower end 21 to heat and evaporate the radio-active liquid in a vessel 18. The combustion gases leave the heat exchanger 19 at the upper end and are channelled to one or more smoke-purifiers 23 and/or one or more gas-scrubbers 24. The use of a heat exchanger is necessary to avoid pollution of the liquid to be evaporated. When the preheating of the burner 3 is completed and boiling of the liquid high-boiler residues commences, the combustion gases from the chamber 15 are fed directly into the vessel 18 by a valve 16. The radio-active concentrate leaves the vessel 18 by means of tubing 26 and the vapour by means of a separator 27 leading to a Raschig-ring column 29 and a cyclone 30. The condensate returns to the vessel 18 and the vapour leaves the column 29 at the upper end and enters a condenser 33. The condensate leaving the condenser 33 at the lower end enters, together with the non-condensable gases and vapours, a separator 35 from which the condensate is removed, the non-condensable gases and vapours passing through a gas-scrubber 24. The liquid high-boiler residues fed from the tank 1 may be those derived from the purification of an organic coolant or moderator liquid after use in a nuclear reactor.
