1. 1. Development of Encapsulated UN-UO₂ Accident Tolerant Fuel

   Författare :Diogo Ribeiro Costa; Pär Olsson; Janne Wallenius; Simon Middleburgh; Magnus Limbäck; Denise Adorno Lopes; Ho Jin Ryu; KTH; []

   Sammanfattning : Accident tolerant fuels (ATFs) are designed to endure a severe accident in the reactor core longer than the standard UO2-Zr alloy systems used in light water reactors (LWRs). Composite fuels such as UN-UO2 are being considered as an ATF concept to address the lower oxidation resistance of the UN fuel from a safety perspective for use in LWRs, whilst improving the in-reactor behaviour of the UO2 fuel.

3. 2. Engineered microstructure composites as means of improving the oxidation resistance of uranium nitride

   Författare :Yulia Mishchenko; Janne Wallenius; Denise Adorno Lopes; Jie Lian; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physics; Fysik;

   Sammanfattning : Owing to its high uranium density and good thermophysical properties,uranium nitride (UN) fuel has been considered as a potential Accident TolerantFuel (ATF) candidate for use in Light Water Reactors (LWRs). However,the main disadvantage of UN is its low oxidation resistance in water/steamcontaining atmospheres at the operating temperatures of LWRs. LÄS MER
