Short answer: Nuclear plants use 316L and 304L stainless for coolant, zirconium for fuel cladding, nickel alloy 690 for steam generators, and carbon steel for containment, so material choices target corrosion and radiation performance; our Corrosion Resistance Guide et Nickel Alloy Supplier give the supporting detail.
At a Glance
Reactor and Coolant Systems
Coolant piping and vessels use Stainless Steel Supplier low-carbon grades, with corrosion notes in our Corrosion Resistance Guide and welding in our Stainless Welding Guide.
Fuel Cladding and Steam
Fuel cladding uses Zirconium Supplier for low neutron absorption, while steam generators use Nickel Alloy Supplier 690 for stress-corrosion resistance; the alloy basis is in our Alloy Steel Supplier.
Containment and Turbines
Containment uses Carbon Steel Supplier and turbines use Cr-Mo-V grades, with strength data in our Comparaison des forces and certification in our Mill Test Certificate Guide.
Quality and Inspection
Nuclear grades need strict NDT and traceability per our Quality Inspection Guide et Export Packing Guide.
