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

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

    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.

  2. 2. Ab initio driven modeling of advanced nuclear fuels

    Författare :Huan Liu; Pär Olsson; Marjorie Bertolus; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; Kärnenergiteknik; Nuclear Engineering;

    Sammanfattning : With the development of clean energy sources such as nuclear power, it has become more important to use advanced nuclear fuels to improve economic efficiency and expand safety margins. Thanks to the high fissile density, high thermal conductivity, and high melting point, uranium nitride and uranium silicide have been considered accident tolerant or high-performance fuels for commercial light water reactors and for future generation reactor systems.
