  1. 1. Accident-tolerant uranium nitride

    Author : Aneta Herman; []
    Keywords : 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

  2. 2. Cold spray Cr-coated Optimized ZIRLO claddings: an option for accident tolerant fuels

    Author : Andrea Fazi; Chalmers University of Technology; []
    Keywords : Cr coating; atom probe tomography; cold spray; accident tolerant fuel;

    Abstract : Accident tolerant fuel development has started with the aim of providing nuclear fuels able to endure severe accident conditions. Research in this field has also sparked a wave of material renewal in the nuclear industry that had being delayed for the last few decades. READ MORE

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

    Author : Luis Guillermo Gonzalez Fonseca; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Uranium nitride; sintering; internal gelation; doping; ATF; microspheres; density; waterproofing.;

    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

  4. 4. High Performance Fuels for Water-Cooled Reactor Systems

    Author : Kyle D. Johnson; Janne Wallenius; James Tulenko; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear fuel; accident tolerant fuel; uranium nitride; uranium silicide; Physics; Fysik;

    Abstract : Investigation of nitride fuels and their properties has, for decades, been propelled on the basis of their desirable high metal densities and high thermal conductivities, both of which oer intrinsic advantages to performance, economy, and safety in fast and light water reactor systems. In this time several key obstacles have been identied as impeding the implementation of these fuels for commercial applications; namely chemical interactions with air and steam, the noted diculty in sintering of the material, and the high costs associated with the enrichment of 15N.

  5. 5. Open porosity fission gas release model applied to nuclear fuels

    Author : Antoine Claisse; Pär Olsson; Arndt Schubert; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nitride fuels have gained a new interest in the last few years as both a candidate for GEN IV reactors and as accident tolerant fuels for current light water reactors. They however are decades behind oxide fuels when it comes to qualication and development of tools to assess their performances. In this thesis, such a tool is developed. READ MORE
