On January 6, 2009, a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $65,000 was issued for a Severity Level III problem involving inattentive security officers at Exelon's Peach Bottom Atomic Power Station. An investigation conducted by the NRC Office of Investigations determined that multiple security officers at Peach Bottom were deliberately inattentive on multiple occasions. In addition, multiple security officers deliberately failed to report observations of inattentiveness to their supervision. These security officers put Exelon in violation of 10 CFR 73.55, which requires armed responders to maintain continuous communication with each alarm station and be available to immediately respond to threats, and Peach Bottom License Condition 2.C(3), which requires, in part, reporting of aberrant behavior.
