  2. 1. Nitride fuel production by the internal sol gel process

    Author : Marcus Hedberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitride fuels; ZrN; internal sol gel;

    Abstract : AbstractDuring operation of a fourth generation reactor system it is necessarily not desirable to utilize an oxide fuel matrix as in light water reactor systems. One type of chemical compounds that has been suggested is nitride based nuclear fuel. READ MORE

  4. 2. Accident-tolerant uranium nitride

    Author : Aneta Herman; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident-tolerant fuel; uranium nitride; chromium; glucose; internal sol-gel;

    Abstract : After the nuclear accident at Fukushima-Daiichi in 2011, a search for alternatives to a current fuel-clad standard UO2-Zircaloy was encouraged by government and industry and novel fuel-clad systems were selected. These systems are often referred to as Accident Tolerant systems, because of an improved response to severe accidents. READ MORE

    Abstract : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. READ MORE

  6. 4. Thermodynamics and Structure of Plate-Like Particle Dispersions

    Author : Maxime Delhorme; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Charge anisotropy; Gel phase; Model clay system; Liquid-crystal phases; Plate-like particles; Simulations; Statistical mechanics;

    Abstract : A considerable amount of mineral particles are found to have a plate-like shape. The work in this thesis concerns theoretical investigations, using Monte Carlo method, of the properties of such particles in aqueous solutions. READ MORE

  7. 5. Advances in Accident Tolerant Fuel Research by Doping of Uranium Nitride

    Author : Luis Guillermo Gonzalez Fonseca; Chalmers tekniska högskola; []

    Abstract : Nuclear energy is a carbon-free energy source alternative often considered less harmful to the environment than fossil fuels. However, accidents have shown that there are some safety concerns regarding nuclear energy that need to be assessed before it can be considered completely safe. READ MORE
