ASME BPVC Section III, Division 1, Subsection NG: Rules for Core Support Structures, 2023

ASME BPVC 2023 Section III, Division 1, Subsection NG outlines the mandatory requirements for the design, construction, inspection, and testing of core support structures in nuclear power plants. As part of the globally recognized ASME Boiler and Pressure Vessel Code, this subsection ensures the structural integrity and operational safety of critical nuclear components.

Highlights:

• Requirements for material selection, qualification, and certification for nuclear-grade components
• Design criteria including design-by-analysis methods, stress limits, and load combinations
• Standards for fabrication techniques including welding, brazing, and mechanical joints
• Acceptance criteria and procedures for nondestructive examination (NDE)
• Hydrostatic and pneumatic test protocols to validate structural reliability
• Guidelines for overpressure protection, relief device approval, and data documentation

Who It’s For:
Nuclear engineers, fabricators, QA/QC professionals, and regulatory specialists responsible for the integrity and compliance of core support structures under ASME nuclear safety standards.
