Critical Valve Requirements

ASME Section III Class 2/3 design: complete material traceability (Certified Material Test Reports — CMTRs) for all pressure-boundary components
N-stamp or NA-stamp: third-party ASME Nuclear Inspector oversight for Class 2 and above
Seismic qualification per IEEE 344 — valves on safety-related systems must withstand Operating Basis Earthquake (OBE) and Safe Shutdown Earthquake (SSE)
Motor-operated valves (MOVs) qualified per IEEE 382 — torque, voltage variation, and harsh-environment performance testing
QA programme per 10 CFR 50 Appendix B (USA) or AERB Safety Guide (India) — design control, procurement document control, inspection, and test records
No substitution of materials without NCR (Non-Conformance Report) and AERB/NRC approval — traceability is mandatory

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What is ASME Section III and why does nuclear require it?
ASME Section III is the Boiler and Pressure Vessel Code for Nuclear Facility Components. Unlike ASME B16.34 (industrial valves), Section III imposes full design analysis, material traceability to mill certificates (CMTRs), N-stamp third-party oversight during manufacturing, and complete quality records. Class 1 covers the primary pressure boundary (reactor coolant), Class 2 covers safety-related secondary systems (ECCS, spent fuel cooling), and Class 3 covers other safety-related systems (service water). Vajra supplies Class 2 and 3 components for balance-of-plant applications.
What is the difference between nuclear Class 2 and Class 3 valves?
ASME Section III Class 2 applies to systems that could affect the safety function of the reactor coolant boundary — e.g., emergency core cooling, spent fuel pool cooling. Class 3 applies to systems important to safety but with a lower direct interface — service water, fire protection, component cooling water. Class 2 requires more rigorous design documentation, full material traceability, and N-stamp inspection. Class 3 has slightly relaxed requirements but still demands CMTRs and a documented QA programme.
