| ENS 49630 | 13 December 2013 17:51:00 | In 2010, changes within the Dominion FFD (Fitness for Duty) program resulted in 11 supplemental personnel not being included in the current random FFD testing program. Two individuals are actively badged at Surry Power Station (SPS) and North Anna Power Station (NAPS). Both individuals accessed the protected area at SPS recently. The other nine individuals were not badged but perform duties that require them to be subject to the FFD program. The affected individuals are now included in the random testing program. An extent of condition was performed and no other contractor records were found to be affected. This event is reportable per 10CFR26.719(b)(4), 'Any programmatic failure, degradation, or discovered vulnerability of the FFD program that may permit undetected drug or alcohol use or abuse by individuals within a protected area, or by individuals who are assigned to perform duties that require them to be subject to the FFD program. The error occurred when, in 2010, it was decided that contract employees would no longer be placed in a select labor pool. When this occurred, FFD personnel no longer monitored that particular labor pool in the belief that it no longer existed. Upon discovery that the labor pool did, in fact, still exist the licensee determined that the eleven personnel should have been included in the random testing program. See similar North Anna report EN #49629. The licensee has notified the NRC Resident Inspector. |
| ENS 48239 | 28 August 2012 10:11:00 | At 0927 EDT on 08/28/2012, it was identified that access to a table H-1 Safe Shutdown Area had been prohibited and that an ALERT had not been declared as required by Surry EPIP-1.01, EAL HA 3.1. At 0900 EDT on 08/27/2012, Electrical Maintenance was performing a surveillance on the Unit 2 Cable Vault and Cable Tunnel Low Pressure CO2 System. A high CO2 level was observed using portable gas detection equipment and access to the space was prohibited for a period of approximately 20 minutes. This report is being made in compliance of VPAP-2802, section 6.3.3(h), which states that a one hour report is required if an Emergency Action Level (EAL) is exceeded, the basis for the emergency class no longer exists at the time of discovery, and no other reasons exist for an emergency declaration. The licensee will notify the NRC Resident Inspector and Virginia Emergency Management Agency.
Based upon initial air monitor readings, EN #48239 reported that an oxygen deficient condition existed in a Table H-1 area for approximately 20 minutes. When the initial information was presented to the Shift Manager on 08/28/2012, it was determined that a one-hour report should have been declared in accordance with EPIP-1.01, Emergency Action Level HA 3.1, which states that an ALERT condition exists if 'access to a Table H-1 area is prohibited due to toxic, corrosive, asphyxiant or flammable gases which jeopardize operation of systems required to maintain safe operations or safely shutdown the reactor.' Since the ALERT condition was not recognized on 08/27/2012, a one-hour report was deemed necessary. A root cause evaluation reviewed the oxygen monitor data and determined that the maximum time of oxygen deficiency was approximately 8 minutes. Operator Time Critical Actions were reviewed to determine whether prohibition of access to the Cable Vault and Cable Tunnel for approximately 8 minutes would jeopardize operation of systems required to maintain safe operations or safely shutdown the reactor. No specific references to activities within this area were identified. Therefore, this event was determined not to be an Alert. The root cause evaluation also noted that Operations was notified of the test, administrative control was established for the CO2 Tank shutoff valve, an Electrician was posted in the control room to notify Operations of alarms associated with the test, a fire watch posted, and the test areas were posted and evacuated. The brief period of time the condition existed did not result in a threat to safe plant operation or the health of plant personnel. Therefore, this event was determined not to be an Unusual Event in accordance with EPIP-1.01, Emergency Action Level HU 3.1, which states, 'report or detection of toxic, corrosive, asphyxiant or flammable gases that have or could enter the Owner Controlled Area in amounts that can affect normal plant operations.' This notification is being made to retract the report made on 08/28/12 based on the above discussion. The NRC Resident (Inspector) has been notified. Notified R2DO (Nease). |
