1. 1. Improved Modelling For Oxidation Of Zircalloy Fuel Cladding Tubes In PWRs

   University essay from KTH/Fysik

   Author : Rafaël Bellachia; [2023]
   Keywords : Nuclear Engineering; Corrosion; Zircalloy; PWR; Nuclear Fuel; Kärnteknik; Korrosion; Zircalloy; PWR; Kärnbränsle;

   Abstract : The fuel cladding is an essential component in the defence-in-depth strategy for nuclear safety. Its integrity and durability are therefore critical for maintaining acceptable safety conditions. However, the integrity of the cladding can be compromised during normal operation due to corrosion and hydriding. READ MORE

3. 2. Fabrication and Characterization of UN-USix Nuclear Fuel

   University essay from KTH/Reaktorfysik

   Author : Alicia Marie Raftery; [2015]
   Keywords : ;

   Abstract : In this thesis, UN-U3Si2 nuclear fuel was fabricated using spark plasma sintering and characterized to analyze the microstructure and crystal structure of the resulting pellets. This work was done in collaboration with accident tolerant fuel research, an effort which aims at developing nuclear fuel with superior safety and performance compared to currently used oxide fuels.

4. 3. Metallic residues after hydriding of zirconium

   University essay from KTH/Materialvetenskap

   Author : Patrik Andersson; Carl-Magnus Arvhult; [2012]
   Keywords : zirconium hydride; ZrH; nuclear fuel; nitride; metallic residues; hydriding; hydrogenation;

   Abstract : As a part of the production of nitride nuclear fuel for use in fast nuclear reactors, zirconium is hydrided followed by nitriding and mixing with uranium nitride. This work concludes a study of unwanted metallic particles present in a powder that is supposed to be a zirconium hydride. READ MORE

5. 4. Manufacturing methods for (U-Zr)N-fuels

   University essay from KTH/Fysik

   Author : Tobias Hollmer; [2011]
   Keywords : nuclear fuel; nitride fuel; uranium nitride; zirconium nitride; spark plasma sintering; solid solution; reaction kinetics; hydriding; nitriding; denitriding; uranium hydride; zirconium hydride; uranium zirconium alloy;

   Abstract : In this work a manufacturing method for UN, ZrN and (U,Zr)N pellets was established at the nuclear fuel laboratory at KTH Stockholm/Sweden, which consists of the production of nitride powders and their sintering into pellets by spark plasma sintering. The nitride powders were produced by the hydriding-nitriding route using pure metal as starting material. READ MORE
