Nuclear industry was the responsible for the discovery and the initial development of magnetic pulse welding on the production of end closures and nuclear fuel rods. The need for a reliable method for joining T91 and ODS steels is central to the fabrication of fuel pins using these materials. Post-joining heat treatment of a fuel pin cladding that does not have detrimental effects on the fuel is practically impossible in a nuclear facility. Whereas other reactor components made from these materials may be discarded due to defective joints, fuel pins must be reopened and the contents recuperated.
Thus the application of any joining technology to fuel pin fabrication demands reliability and simplicity of operation.
It can potentially make joining of these materials simple, reliable and repeatable. It involves no physical contact with the cladding at the joint, which could even enable the joining of cladding materials with dedicated coatings.
Testing Magnetic Pulse Equipment on such coated cladding is one of the priorities of the next stage of investigation.
