  1. 1. Accident-tolerant uranium nitride

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

    Sammanfattning : 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. LÄS MER

  3. 2. Development of Encapsulated UN-UO₂ Accident Tolerant Fuel

    Författare :Diogo Ribeiro Costa; Pär Olsson; Janne Wallenius; Simon Middleburgh; Magnus Limbäck; Denise Adorno Lopes; Ho Jin Ryu; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Accident tolerant fuel; UN-UO2 composite fuel; coating technology; powder coating; chemical vapour deposition CVD ; physical vapour deposition PVD ; UN spheres; spark plasma sintering; Kärnenergiteknik; Nuclear Engineering;

    Sammanfattning : Accident tolerant fuels (ATFs) are designed to endure a severe accident in the reactor core longer than the standard UO2-Zr alloy systems used in light water reactors (LWRs). Composite fuels such as UN-UO2 are being considered as an ATF concept to address the lower oxidation resistance of the UN fuel from a safety perspective for use in LWRs, whilst improving the in-reactor behaviour of the UO2 fuel.

  4. 3. Development and performance evaluation of accident-tolerant coated fuel claddings for light water reactors

    Författare :Andrea Fazi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVD; oxidation; accident tolerant fuel; autoclave; cold spray; nitride coatings; Cr coating;

    Sammanfattning : The development of accident tolerant fuel has 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 been delayed for the last few decades. LÄS MER

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

    Författare :Andrea Fazi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cr coating; atom probe tomography; cold spray; accident tolerant fuel;

    Sammanfattning : 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. LÄS MER

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

    Författare :Luis Guillermo Gonzalez Fonseca; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uranium nitride; sintering; internal gelation; doping; ATF; microspheres; density; waterproofing.;

    Sammanfattning : 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. LÄS MER
