  2. 1. Neutronics in Molten Salt Reactors

    Author : Anders Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; one-group theory; Green s function; two-group theory; Molten Salt Reactors; neutron noise;

    Abstract : This thesis contains two studies of the MSR properties. The firstuses one-group theory and data that correspond to a traditionaluranium fuelled light water reactor to investigate the basis physicaldifferences that might arise duesolely to the movement of the fuel. READ MORE

  4. 2. Alloys in Contact with Molten Salts for Thermal Storage Applications

    Author : Esraa Hamdy Mohamedin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase transition; Molten salts; High-temperature corrosion; Alumina-forming alloys; Carburisation; Thermal energy storage TES ; Laves phase; Concentrated solar power CSP ;

    Abstract : The combination of a concentrated solar power (CSP) plant and a thermal energy storage (TES) system is a promising technology for power generation, in that it overcomes the challenges commonly faced by renewable energy systems, such as intermittency, dispatchability, and the gap between the energy supply and energy demand. The third generation (Gen3) CSP plants are designed to increase plant efficiency by using supercritical carbon dioxide (sCO2) instead of steam for the Brayton cycle gas turbines, requiring a minimum operating temperature of 750°C for the TES materials.

  5. 3. Neutronics in reactors with propagating perturbations

    Author : Anders Jonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; one-group theory; Green s function; Molten Salt Reactors; two-group theory; neutron noise; propagating perturbations;

    Abstract : This thesis contains several studies of the properties of neutron noise, primarily in Molten Salt Reactors and other reactors with propagating perturbations. Both one- and two-group diffusion theory are employed to investigate the differences that arise from the movement of the fuel. READ MORE

  6. 4. Nuclear safeguards directed to the application of multivariate analysis techniques to existing and future nuclear fuel cycles

    Author : Vaibhav Mishra; Sophie Grape; Zsolt Elter; Erik Branger; Peter Dendooven; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear safeguards; nuclear fuel verification; spent fuel; molten salt reactors; machine learning.; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Abstract : For as long as nuclear power has existed, there has been a concern for effectively safeguarding nuclear material since it was learned that it could be misused. Early on, many nations were interested in nuclear power, and therefore there was an urgent need to verify that it was only used for civilian purposes. READ MORE
