Two radiographs of the same jar of glass shards side by side, labelled X-ray and N-ray. The X-ray image shows only bright overlapping glass fragments; the N-ray image renders the glass nearly transparent and reveals a plastic toy figure standing inside the jar.

Neutron-based inspection: finding corrosion under insulation

X-rays see metal and miss water. Neutrons invert that contrast, which is what lets N-ray and neutron backscatter find CUI without stripping the cladding.

Cross-section schematics of the four wet H2S damage morphologies — stepwise HIC cracking, a surface blister, a weld-toe SSC crack, and a stacked SOHIC array beside a weld

Wet H2S damage: blistering, HIC, SOHIC and SSC

Four cracking mechanisms attack carbon steel in wet sour service. What drives each one, and why plate steel quality, hardness and residual stress decide who cracks.

Detecting corrosion from drone images with computer vision

External visual inspection is manual, subjective, and often blocked by access. An AI-based computer vision model reading drone imagery changes what a screening pass costs.
