Kairos Power has commissioned an automated line at its Albuquerque manufacturing campus that inspects fuel pebbles and marks each one with a unique code. Each pebble is measured and laser-scanned before it is packed or loaded into test platforms. The company says the line builds in-house traceability for the Hermes 2 plant in Oak Ridge, Tennessee.

## Key facts

- The near-term target is 70,000 inspected pebbles for test platforms, including the second Engineering Test Unit.
- An infrared laser engraves three redundant data-matrix codes about half a millimeter deep into each pebble's graphite shell; each code links to the pebble's dimensions, density, batch and inspection status.
- Diameter, geometry and density are measured in real time, and lasers scan the surface down to the micron level.
- The article gives no throughput rate or accuracy percentage for the line.
