What action is taken when an item is certified for nuclear safety?

When an item is certified for nuclear safety, it is documented in the Master Nuclear Certification List (MNCL). This list serves as an official record that indicates the item has been evaluated and verified to meet specific safety criteria necessary for handling, maintaining, and using items in a nuclear environment. This documentation is crucial for ensuring that all personnel are aware of items that are deemed reliable and safe for operations that involve nuclear materials. It provides a traceable reference to track the safety status of these items, which is essential for regulatory compliance and risk management in nuclear operations.
