Reliable nuclear inspection is fundamental to safety, regulatory compliance and long-term asset integrity. Sonaspection manufactures representative flawed specimens, mock-ups and calibration blocks that support inspection qualification, procedure development, NDT/NDE training and performance demonstration throughout the nuclear lifecycle.
Our flawed specimens and mock-ups can be manufactured to support nuclear inspection codes and standards, including ASME Section V, ENIQ, RCC-M, BS EN ISO 9712, ASTM and customer specific qualification programs.
Flaws can be implanted into plates, pipes, nozzles and reactor vessel components in a range of materials, including stainless steel, carbon steel, dissimilar weld metals and composites.
They help support:
Standard and custom calibration blocks designed around the component geometry, material and inspection code requirements, including ASME Section V and performance demonstration.
Purpose-built flawed specimens containing accurately positioned flaws for inspection procedure development, NDT/NDE training, personnel qualification and equipment validation.
Small and large-scale complex mock-ups manufactured to replicate nuclear components, inspection access and realistic inspection conditions.
ASME Section XI Appendix VII and VIII specimen sets manufactured to support applicable code and performance demonstration requirements.
Representative flawed specimens allow inspection teams to evaluate whether procedures, equipment and personnel can reliably detect and characterize relevant flaws before an inspection is deployed.
They can support nuclear organizations by helping to:
Whether you’re developing a new inspection procedure, validating equipment performance or designing representative specimens, our team will work with you to find the right solution.
