If a safety limit is exceeded, which sequence of actions is required?

• A. Plant continues with reduced power
• B. The reactor is shut down; Commission notified; matter reviewed; results recorded including cause and corrective action; operations cannot resume until Commission authorization
• C. Only operator records the event
• D. Only Commission is notified

Answer: (B)

When a safety limit is exceeded, the priority is to bring the plant to a safe state and start a formal follow-up process. The reactor is shut down to stop the abnormal condition and protect fuel integrity and safety. Regulator oversight requires promptly notifying the Commission about the event, so they’re aware of what happened and can oversee the response. A formal review is then conducted to determine the cause, define corrective actions, and document the results, including what was changed or improved. Operations cannot resume until the Commission has authorized restart, ensuring the issue is fully addressed and it’s safe to return to service. This approach ensures immediate protection, accountability, and a clear path to preventing recurrence.
