  2. 1. 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

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

    Author : Luis Guillermo Gonzalez Fonseca; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; 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

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; internal gelation; density; Uranium nitride; sintering; microspheres; doping; waterproofing.; ATF;

    Abstract : Nuclear energy is a carbon-free energy source 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 continuously assessed and further improved. READ MORE

  7. 5. High Performance Fuels for Water-Cooled Reactor Systems

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

    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.
