On April 23, 2007, a Severity Level III Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $130,000 was issued to Entergy Nuclear Operations, Inc. for failure to meet the requirements of a Confirmatory Order (EA-05-190) issued on January 31, 2006. The Order required that the licensee provide and maintain a backup power supply for the Indian Point Emergency Notification System (ENS). Specifically, the "radio only activation" feature, the portion of the ENS for which the backup power capability was provided, was required to meet its test acceptance criteria by April 15, 2007. The licensee did not meet its test acceptance criteria, resulting in the ENS not being fully operable by April 15, 2007.
