  2. 1. Production and Characterization of ZrN and PuN Materials for Nuclear Fuel Applications

    Author : Marcus Hedberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal gelation; Carbothermal reduction; Zirconium Nitride; Plutonium Nitride; Nuclear fuel;

    Abstract : At the heart of a nuclear reactor resides its fuel. The chemical composition of the nuclear fuel affects the performance of several key properties important for the overall operation and safety performance of the reactor. READ MORE

  4. 2. Advanced fuels for thermal spectrum reactors

    Author : Jitka Zakova; Janne Wallenius; Jan-Leen Kloosterman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BWR; transmutation; thorium; Pu; MA; Am; Cm; AHTR; thermal; reactor; neutron;

    Abstract : The advanced fuels investigated in this thesis comprise fuels non− conventional in their design/form (TRISO), their composition (high content of plutonium and minor actinides) or their use in a reactor type, in which they have not been used before (e.g. nitride fuel in BWR).

  5. 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
