What certifications are required for nuclear power plants valves in Zagreb?
For nuclear power plants in Zagreb, the applicable standards are: ASME Section III (Class 2/3), ASME B16.34, IEEE 382 (MOV), IEEE 344 (Seismic), 10 CFR 50 Appendix B, AERB (India), NRC Regulatory Guides. All valves are supplied with full documentation including material test reports (EN 10204 3.1/3.2), pressure test certificates, and dimensional inspection reports.

What is the delivery time for nuclear power plants valves to Zagreb?

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.
