  • Publication number: 20180322968
    Abstract: A gas-cooled pressure tube nuclear reactor is described that uses a room temperature and pressure gas as a primary coolant and a liquid moderator as a secondary coolant. The primary coolant, which may be maintained in a supercritical state, is circulated through fuel columns in a pool of the liquid moderator. The primary coolant removes the heat generated by fission from the nuclear fuel. The heated primary coolant is then passed to one or more turbines to generate power. The primary coolant is then repressurized by one or more compressors using some of the generated power from the turbines. Several modified Brayton cycle configurations are described that are uniquely suited to the operating conditions of the gas-cooled pressure tube reactor.

  • Patent number: 9721678
    Abstract: A duct for a nuclear fuel assembly includes a tubular body and an elongated member. The tubular body has a sidewall with an inner face and an outer face and is configured to contain nuclear fuel within a fuel region. The elongated member extends from the outer face along at least a portion of the fuel region and has a contact surface configured to stabilize the duct during operation of the nuclear fuel assembly.

  • Patent number: 9362010
    Abstract: In response to a change in a thermal operational parameter in a nuclear fission reactor, reactivity is controlled by driving a neutron absorption parameter modifying material to or from a region of the core of the nuclear fission reactor. The apparatus includes a driver material disposed in a first reservoir portion and a second reservoir portion of a first reservoir and connected by a first conduit. A high-Z material may be distributed in the driver material. The neutron absorption parameter modifying material is disposed in both a second reservoir and the second reservoir portion of the first reservoir. A portion of the neutron absorption parameter modifying material is in physical contact with a portion of the driver material in the second reservoir portion. The neutron absorption parameter modifying material is driveable by the driver material between the second reservoir portion and the second reservoir through a second conduit.

  • Publication number: 20100206527
    Abstract: A method for in-situ treatment of a metallic surface utilizing a nanoparticle dispersion to increase at least one of (i) the critical heat flux. (ii) the boiling heat transfer rate, or (iii) the corrosion resistance of the metallic surface when in operation without a nanofluid heat transfer liquid, comprising: (1) cleaning the metallic surface: (2) conditioning the metallic surface to enhance nanoparticle binding to the metallic surface by applying a polymeric binding agent; (3) forming at least one thin film layer of nanoparticles on the metallic surface by contacting the nanoparticle dispersion with the metallic surface at a temperature and pressure sufficient to boil the nanoparticle dispersion; and, optionally (4) curing the nanoparticle layer by heating the metallic surface to a temperature higher than the temperature sufficient to boil the nanoparticle dispersion.
