ASME Nuclear Inspections

As an ASME Authorized Inspection Agency, we provide teams of Authorized Inspectors who verify that pressure equipment intended for nuclear power plants meets the technical and safety requirements of ASME Section III. Our inspectors possess extensive nuclear sector experience and qualifications.

Path to nuclear certification marks

We guide manufacturers through obtaining the ASME Certificate of Authorization and the relevant Nuclear Certification Marks — N, NA, NPT, NS and N3. This encompasses application preparation, Quality Assurance Manual development, personnel qualification verification, NDE procedure approval, demonstration sample supervision, and welding procedure and welder verification.

The ASME Survey

The typical timeline from application to certificate issuance is approximately six months. A central step is the ASME Survey — an audit by an ASME Team (three members plus two members appointed by the Authorized Inspection Agency) which evaluates the demonstration item and the implementation of the manual. The ASME Conformity Assessment Department then issues the Authorization Certificate and the certification mark.

Beyond inspection

Our service extends beyond Code compliance to include support in the application and interpretation of the Code — drawing on our parent organization's position as one of very few inspection bodies in the world holding both ASME AIA authorization and ISO 19443 accreditation.
