Transitioning in nuclear from the U.S. Navy to the commercial industry was always a goal for me, but stepping directly into a fully digital control room was a paradigm shift. Moving from the tactile, analog world of my military background to the data-rich environment of modern advanced reactors was jarring. Digital systems offer an unprecedented wealth of information, but unlocking that potential requires a fundamental shift in how we approach testing, commissioning, and startup.

Commissioning analog plants meant physical verification, such as lifting leads, injecting signals, and manually tweaking potentiometers to calibrate gains and offsets. Digital instrumentation and control (I&C) completely redefines this landscape. Today, nearly all plant data are available at our fingertips, but this brings the challenge of filtering an immense amount of data and system alarms. Troubleshooting has largely migrated from the field and into software, following digital signals from operator inputs to field devices.
