Thee Birth of 10 CFR Part 73.54
In 2009, thee NRC issued a final rule that added cyber security requirements to regulations. This rule, criofid at 10 CFR Part 73.54, became effective on March 27, 2009. The regulation requidud each nuclear power plant licensee to submit a cyber security plan that adred thee protection of digital computr and communication systems and networks that are associated with safety, sequity, and emergency preciness. The delline fail initals 2010, with full implementation by 2013.

NUREG- 1801 and Updating the Design Basis Threat
