Which option is NOT a required action when a safety limit is exceeded?

• A. Immediately resume operations
• B. The reactor is shut down
• C. Commission notified
• D. Record results

Answer: (A)

Exceeding a safety limit triggers protective actions to bring the plant to a safe state, not to keep operating. The reactor should be shut down to stop fission, the appropriate commission or regulatory body must be notified, and the event with its results should be recorded for investigation and learning. These steps ensure safety, accountability, and compliance. Immediately resuming operations ignores the unsafe condition and is not a required action, which is why that option is the correct choice for what is NOT required.
