Which items must be listed in the Master Nuclear Certification List (MNCL) to be used in nuclear operations?

• A. Material Handling Equipment (MHE)
• B. Software
• C. Facility Hoists
• D. All of the above

Answer: (D)

The MNCL exists to capture every item that requires formal certification before it can be used in nuclear operations. Material Handling Equipment, facility hoists, and software all fit this requirement because each category can directly affect safety and operational control. Material handling equipment moves radioactive materials and components, so it must be qualified and documented. Facility hoists perform lifting tasks that impact worker safety and radiological controls, so they require certification as well. Software used in safety‑critical systems, monitoring, or control functions must be qualified, tested, and maintained under MNCL oversight. Since all of these kinds of items can influence nuclear safety and mission-critical operations, they all must be listed. Therefore, the correct approach is to include all of these items on the MNCL.
