1. 1. Propagation of Nuclear Data Uncertainties for Reactor Physics Parameters in Fluorine-19-based Molten Salt Reactors

   Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Sigfrid Stjärnholm; [2023]
   Nyckelord :;

   Sammanfattning : It could be argued that a renaissance is taking place for the global interest in nuclear power - especially for the development of the next generation of reactor systems that aim at solving the problems with contemporary energy production with nuclear technology. One such proposed concept for Gen IV nuclear power is a Molten Salt Reactor (MSR), in which the nuclear fuel is in solution of a salt - often based on fluorine or chlorine. LÄS MER

3. 2. Ghosts of Our Past: Neutrino Direction Reconstruction Using Deep Neural Networks

   Kandidat-uppsats, Uppsala universitet/Högenergifysik

   Sammanfattning : Neutrinos are the perfect cosmic messengers when it comes to investigating the most violent and mysterious astronomical and cosmological events in the Universe. The interaction probability of neutrinos is small, and the flux of high-energy neutrinos decreases quickly with increasing energy. LÄS MER
