What clarification did FERC Order 706-B provide?

FERC Order 706-B clarified that all nuclear facilities, regardless of their regulatory status with the Nuclear Regulatory Commission (NRC), are required to comply with the NERC Critical Infrastructure Protection (CIP) standards. This directive ensured a uniform security framework across all nuclear facilities, emphasizing the importance of maintaining robust cybersecurity measures in protecting critical energy infrastructure.

The inclusion of all nuclear facilities under NERC CIP reflects the recognition of their critical role in the electric grid and the necessity for stringent cybersecurity practices to mitigate risks associated with cyber threats. By mandating compliance across the board, FERC aimed to enhance overall grid reliability and security, ensuring that all potential vulnerabilities in the nuclear sector are addressed.

The other options do not align with the intent or content of FERC Order 706-B. For instance, while some facilities may fall under various regulatory bodies, the emphasis here was on uniform compliance rather than exemptions or specific asset classifications. As such, the order represented a proactive measure in fortifying cybersecurity across the essential infrastructure tied to energy production and distribution.
