  1. 1. Friction stir welding of copper canisters for nuclear waste

    Författare :Therese Källgren; Rolf Sandström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Friction Stir Welding FSW ; Copper; Welding; Finite Element Method FEM ; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The Swedish model for final disposal of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. One of the methods to seal the copper canister is to use the Friction Stir Welding (FSW), a method invented by The Welding Institute (TWI). LÄS MER

  3. 2. Investigation and modelling of friction stir welded copper canisters

    Författare :Therese Källgren; Rolf Sandström; Hannu Hänninen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction Stir Welding FSW ; Copper; Welding; Finite Element Method FEM ; SKB; Material flow; Materials science; Teknisk materialvetenskap;

    Sammanfattning : This work has been focused on characterisation of FSW joints, and modelling of the process, both analytically and numerically. The Swedish model for final deposit of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. LÄS MER
