News & Views Issue 56 is here, and it’s one of our most wide-ranging issues yet.
The cover of this issue features a longstanding inspection challenge in nuclear power: achieving full ultrasonic coverage of shrunk-on disk bore and keyway regions on a Siemens 13.9m² low-pressure turbine rotor — without de-stacking the rotor. SIA redeveloped its automated phased array ultrasonic testing protocol using advanced CAD modeling and simulation, achieving 100 percent disk bore coverage across all six disks within a predictable five-day outage. The validated protocol supports defensible rotor life assessments for nuclear utilities. Issue 56 also
