    Sammanfattning : The fast breeder is a type of nuclear reactor that aroused much attention in the 1950s and 60s. Its ability to produce more nuclear fuel than it consumes offered promises of cheap and reliable energy, and thereby connected it to utopian ideas about an eternal supply of energy. LÄS MER

  2. 2. Science and Technology for Americium Transmutation

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Milan Tesinsky; KTH.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Americium could be seen as the most troublesome element that is presentin nuclear fuel. This thesis offers different points of view on the possibility ofamericium transmutation. The first point of view elaborates simulations ofamericium-bearing facilities, namely nuclear data, a popular computationalcode and modeling techniques. LÄS MER

  3. 3. High Performance Fuels for Water-Cooled Reactor Systems

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Kyle D. Johnson; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear fuel; accident tolerant fuel; uranium nitride; uranium silicide; Physics; Fysik;

    Sammanfattning : 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.

  4. 4. Mechanistic Modeling of Wall-Fluid Thermal Interactions for Innovative Nuclear Systems

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Roman Thiele; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GEN-IV reactors; Wall heat transfer; Computational Fluid Dynamics; Wall functions; Reactor design; Supercritical water; Liquid metal; Energiteknik; Energy Technology; Physics; Fysik;

    Sammanfattning : Next generation nuclear power plants (GEN-IV) will be capable of not only producing energy in a reliable, safe and sustainable way, but they will also be capable of reducing the amount of nuclear waste, which has been accumulated over the lifetime of current-generation nuclear power plants, through transmutation. Due to the use of new and different coolants, existing computational tools need to be tested, further developed and improved in order to thermal-hydraulically design these power plants. LÄS MER
