  3. 2. Studies of Nuclear Fuel Performance Using On-site Gamma-ray Spectroscopy and In-pile Measurements

    Författare :Ingvar Matsson; Anders Bäcklin; Ane Håkansson; Björn Grapengiesser; Riitta Kyrky-Rajamäki; Uppsala universitet; []
    Nyckelord :Nuclear physics; fission gas release; nuclear fuel; core physics; gamma-ray spectroscopy; LOKET; thermal power; burnup; fuel failure; validation; cladding; Kärnfysik;

    Sammanfattning : Presently there is a clear trend of increasing demands on in-pile performance of nuclear fuel. Higher target burnups, part length rods and various fuel additives are some examples of this trend. LÄS MER

  4. 3. Delayed Hydride Cracking in Irradiated Zircaloy

    Författare :Pål Efsing; Kjell Pettersson; Christopher Coleman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrides; hydrogen; embrittlement; delayed cracking; fracture toughness; fracture resistance; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Under some circumstances nuclear fuel cladding tubes made from zirconium based alloys may develop long axial cracks. The formation of these cracks is mainly thought to be connected with the oxiditian and hydriding of the cladding which takes plage after the the formation of a small primary defect. LÄS MER
