Many nuclear applications rely on zirconium (Zr) alloys and stainless steels (SS) for key cooling system components including future designs such as a supercritical water cooled reactor (SCWR). In the present work, tubular sections of Zr and SS with a 55 mm nominal diameter were rotary friction welded at 1000 RPM and 1200 RPM with a 20% variation in burn-off pressure.
