  1. 1. Accelerator-driven systems : safety and kinetics

    Author : Marcus Eriksson; Janne Wallenius; Hamid Aït Abderrrahim; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : The accelerator-driven system (ADS) is recognized as a promising system for the purpose of nuclear waste transmutation and minimization of spent fuel radiotoxicity. The primary cause for this derives from its accelerator-driven, sub-critical operating state, which introduces beneficial safety-related features allowing for application of cores employing fuel systems containing pure transuranics or minor actinides, thereby offering increased incineration rate of waste products and minimal deployment of advanced (and expensive) partitioning and transmutation technologies.

  2. 2. Source efficiency and high-energy neutronics in accelerator-driven systems

    Author : Per Seltborg; Waclaw Gudowski; Enrique González-Romero; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic physics; Atomfysik;

    Abstract : Transmutation of plutonium and minor actinides in accelerator-driven systems (ADS) is being envisaged for the purpose of reducing the long-term radiotoxic inventory of spent nuclear reactor fuel. For this reason, the physics of sub-critical systems are being studied in several different experimental programs across the world. READ MORE

  3. 3. Neutronic and burnup studies of accelerator-driven systems dedicated to nuclear waste transmutation

    Author : Kamil Tucek; Jan Wallenius; Massimo Salvatores; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik;

    Abstract : Partitioning and transmutation of plutonium, americium, and curium is inevitable if the radiotoxic inventory of spent nuclear fuel is to be reduced by more than a factor of 100. But, admixing minor actinides into the fuel severely degrades system safety parameters, particularly coolant void reactivity, Doppler effect, and (effective) delayed neutron fractions. READ MORE

  4. 4. External Source Effects and Neutronics in Accelerator-driven Systems

    Author : Per Seltborg; KTH; []
    Keywords : ;

    Abstract : Transmutation of plutonium and minor actinides inaccelerator-driven systems (ADS) is being envisaged for thepurpose of reducing the long-term radiotoxic inventory of spentnuclear reactor fuel. Consequently, the physics of sub-criticalsystems are being studied in several different experimentalprograms across the world, one of them being the MUSE(MUltiplication of External Source) program.
