Happy Holidays! Our offices are closed from 17:30 on Tuesday 23 December and will reopen on Monday 5 January 2026.

Inspection confidence throughout the nuclear lifecycle

Flawed specimens and mock-ups for nuclear inspection

Supporting inspection qualification, procedure development, NDT/NDE training and performance for new build, SMR and operating nuclear facilities.

Engineered for inspection readiness

Representative specimens for challenging inspections

Reliable nuclear inspection begins before deployment, with representative components that allow procedures, equipment and personnel to be evaluated under realistic conditions.

We manufacture flawed specimens, mock-ups and calibration blocks around the required component geometry, material, inspection method and qualification objective.

nuclear inspection applications

Supporting every stage of the nuclear lifecycle

01 New build and smrs

Build inspection capability before deployment

Develop and validate inspection approaches for emerging reactor designs, supply chain components and new construction programmes.

From procedure to performance

Designed around the inspection objective

Each specimen can be developed to support a defined stage of inspection readiness and qualification.

✓  Inspection procedure development and validation

✓  Inspection qualification and performance demonstration

✓  NDT/NDE training and personnel qualification

✓  Equipment setup, calibration and validation

✓  Probability of detection studies
