How frequently should the Operating Plan for loss of Primary Control Center be tested to ensure its effectiveness?

The effectiveness of the Operating Plan for the loss of the Primary Control Center should be tested at least annually to ensure that all personnel are familiar with the procedures and that any necessary updates can be made in response to changes in systems, technology, or operational procedures. Annual testing helps ensure that operators retain the knowledge and skills needed to execute the plan under pressure and confirms that the plan remains relevant and effective in managing potential risks associated with losing critical control capability. This timeframe also aligns with best practices in emergency preparedness and response planning, allowing operators to perform drills and training exercises effectively while considering operational cycles and available resources.

Testing too frequently, such as monthly or quarterly, may lead to diminishing returns, as personnel might become desensitized to the drills, while testing every six months could risk significant lapses in readiness if critical changes occur in between tests. An annual schedule strikes a balance between maintaining readiness and managing operational demands, thus ensuring that the organization can effectively respond in a real emergency.
