Neutron Radiographic Testing (NR)
Method Overview
High-penetration thermal neutron beam imaging to evaluate internal components, contrast organic matter, or view shielded materials.
Core Method Specifications
Target Applications & Governing Standards
1 Scopes ConfiguredMethod Limitations & Operational Boundary Conditions
Critical physics limits, thermal envelopes, blind spots, and ASME Sec V / API procedural boundaries for NR.
Components must be evaluated for residual neutron activation before handling.
Zero dead zone
Planar cracks must align parallel to the collimated neutron beam axis
- •Hydrogen-shielded assemblies: Materials containing boron, cadmium, or hydrogenous fluids stop the neutron beam completely
- •Cannot be deployed in typical field or refinery turnaround environments (facility-bound method)
Residual cleaning solvent or atmospheric moisture trapped in crevices mimicking internal adhesive bonds
X-ray radiography provides the metallic density inverse of neutron radiographic images
Industrial X-ray CT scanning for accessible non-nuclear precision assemblies
