About the ASME Nuclear Component Certification Program
ASME has played a vital role in supporting the nuclear power industry since the first publication of the ASME BPVC, Section III, "Rules for Construction of Nuclear Facility Components" in 1963. The commencement of the ASME Nuclear Certification Program in 1968 has only strengthened that support.
N-type and G-Type Certificates of Authorization issued by ASME signifies that a Certificate Holder has been through a rigorous survey to verify the adequacy and effective implementation of the quality assurance program. These Nuclear Certificates of Authorization allow Certificate Holders to certify and stamp newly constructed components, parts, and appurtenances used at a nuclear facility with the Certification Mark in accordance with Section III of the ASME BPVC. The Society issues different Nuclear type certificates such as N-type, G-type certificates, and an owner's certificate that authorizes the following scope of activities:
- N - Vessels, pumps, valves, piping systems, storage tanks, core support structures, concrete containments, and transport packaging
- NA - Field installation and shop assembly of all items
- NPT - Parts, appurtenances, welded tubular products, and piping subassemblies
- NS - Supports
- NV - Pressure relief valves
- N3 - Transportation containments and storage containments
- OWN - Nuclear power plant owner
- G - Design of Graphite or Composite Core Components and Assemblies
