What is the only source used to verify nuclear certification status?

• A. Nuclear Certification Registry
• B. MNCL Registry
• C. The Master Nuclear Certification List (MNCL)
• D. Master Nuclear Certification Ledger

Answer: (C)

The Master Nuclear Certification List is the official, centralized record that tracks who holds nuclear certification, the level of certification, and whether it is current or expired. This list is the authoritative source used for verification during personnel reliability checks, audits, and access determinations. Other registries or ledgers may be mentioned in informal contexts, but they are not the official repository for certification status. Verifying against the MNCL ensures you have the most accurate and up-to-date information on an individual’s nuclear certification.
