PWR fuel rod weld inspection method, metallographic inspection and X-ray inspection1 ScopeThis document describes the metallographic inspection and X-ray inspection methods for welds of PWR fuel rods (hereinafter referred to as fuel rods). The metallographic inspection method in this document is applicable to the fusion welding of zirconium alloy fuel rods welded by electron beam and tungsten inert gas protection. Inspection of penetration, defects and microstructure of samples of seams (including girth welds and sealed welds). Also suitable for zirconium bonding by pressure resistance welding Inspection of the dense area of welds welded by gold fuel rods. The thin film etching method is only applicable to Zr-Sn alloy fuel that uses electron beam welding Bar weld inspection. The weld penetration depth and defects of the zirconium alloy guide tube in the fuel assembly and the metallographic inspection of the weld obtained by other welding methods can also be referred to implement. The X-ray inspection method in this document is applicable to the inspection of fuel rod girth welds and sealing welds, and the control of PWR fuel assemblies Circumferential welds of rods, combustible poison rods, neutron source rods and guide tube components, and other stack-type similar fuel rods can also be implemented by reference.2 Normative referencesThe content of the following documents constitutes an indispensable clause of this document through normative references in the text.
