ENS 47080	20 July 2011 20:45:00	A contractor supervisor had a confirmed positive for alcohol during a random fitness-for-duty test. The contractor's access to the plant has been terminated. Contact the Headquarters Operations Officer for additional details. The licensee informed the NRC Resident Inspector.
ENS 48030	15 June 2012 16:00:00	At 1958 (EDT) on 4/22/2012, Oconee emergency power (Keowee Hydro Station Units 1 and 2) automatically started based upon an invalid signal. In progress at the time was the Unit 3 Keowee Emergency Start Channel B Isolations section of the Unit 3 Engineered Safety Features Actuation System Replacement Modification procedure. A step in this procedure provided direction for a jumper to be connected between links B-13 and B-14. However, this jumper was placed between links A-13 and A-14, which caused the start of the Keowee units. During the period the jumpers were inadvertently installed, the Keowee units remained operable and available to supply emergency power to Units 1, 2, and/or 3. Both Keowee units were shutdown from the inadvertent emergency start actuation and the emergency start signal was reset per procedure at 0156 (EDT) hours on 4/23/2012. The cause for the misplaced jumper was determined to be a human performance error by the technicians. As required per NUREG 1022, Rev.2 the following information is provided: (a) The specific train(s) and system(s) that were actuated: In this event, both Keowee Hydro Units 1 and 2 actuated because of the emergency start signal being generated by Channel A. (b) Whether each train actuation was complete or partial: The automatic actuation of the Keowee units was completed. (c) Whether or not the system started and functioned successfully: No problems or issues were identified with the performance of the Keowee Hydro Units in response to the emergency start. Therefore this condition is being reported for Oconee 1, 2, and 3 as an invalid actuation under 10 CFR 50.73 (a)(2)(iv)(A), which allows NRC notification via telephone per 10 CFR 50.73(a)(1). Corrective Actions: - Work was stopped on the Unit 3 Engineered Safety Features Actuation System Replacement Modification procedure; - Immediate investigation was conducted to determine the impact of the jumper activity as well as development of a recovery plan; and - The jumper was removed from links A-13 and A-14 and the Keowee units were shutdown. The NRC Resident Inspector was informed.
ENS 49291	20 August 2013 11:49:00	A non-licensed contract supervisor had a confirmed positive fitness for duty test. Plant access for the individual has been terminated. The licensee has notified the NRC Resident Inspector.
