Description

Development work by TWI on behalf of the Swedish Nuclear Fuel & Waste Management Co. for the EB and friction stir welding of lids onto Cu radioactive waste disposal canisters (1050 mm diameter, 50 mm wall thickness) is reviewed. In 1986, when the project began, the only feasible welding process for a such a thickness of high thermal conductivity metal was high power EB welding. The invention of friction stir welding in 1991 provided a viable alternative, and a full size canister welding machine has been built. Both welding processes have been extensively modelled and studied experimentally, using test pieces of increasing size and complexity.
