Southern Nuclear Oerating Company Nuclear NMP-EN-002 COuMPOr*O1* Management Actios for Potential Groundter Contamination Events Version 2.0 Procedure I Contam.natn I Page 10 of 10 10 CFR 50.75(g) Leak/Spill Decommissioning Record (R-type GG3.100)

PART 1 - Location/Source Event Date Plant Name: Individual Contact Name: Check one: Leak? Spill?

041.6/J 2009 E..-Hatch . Don Gilbert X Volume (gallons): Location of spill/leak Source of spill/leak unknown Groundwater sample well T3. Groundwater and unknown source Duration of leak/spill: Unknown Gamma Activity (uCi/cc) Tritium Activity (pCi/L) Total Area Impacted (f2)

A4iSt'Voe 34,300 T3 sample well PART 2- Event Description Outside of Protected Area? E0 Yes 0 No [I Unknown unknown, what action needed to D determine? vI Description of eventfllsue Elevated tritium activity discovered in groundwater sampling location (well T3). Concentration on 4/16109 was 36,500 pCi/L. Verification sample collected on 5/6009 was 34,300 pCi/L. Samples were obtained in accordance to groundwater sampling program per 64CH-SAM-028.

Actions Taken to Stop Spill or Leak Sample frequency at this sample point to be increased to monitor trends in order to evaluate further corrective actions.

Enhance scrutiny of other tritium sampling points for anything unusual which could be connected to this event, especially the 8A discharge sampler since the subsurface drain line passes near this well.

Actions Taken to Clean-up Spill or Leak and Long Term Monitoring Sample frequency at this sample point to be increased to monitor trends in order to evaluate further corrective actions.

Description of Condition:

.on.may 5th 2009w data report from Georgia Power Central (GPC) Lab contakting. tuitium activity results for ground water sample well T3 was received and reviewed for input Into Chemistry database. Activity for gr Water sample well T3 was observed to be elevated (36.500 pC/L). This concentration had Increased from last sample activity (5400 pCV/L). Chemistry personnel were directed to resample for verification. A sample was collected on 5/6/09 and shipped toGPC Lab. Sample results for verification samplewere received 5/11/09 and these results were equal to 34,300 pCI/L Chemistry Manager has notified the resident NRC Inspector as well as SNCenvIronmental affairs. Cooperate Is performing hewnecessary notifications to the State within appropriate time as per NMP-EN-002.

  • NOTE Because an offsite governmental agency (GA EPO) will be notified of this event, an NRC 4-hour notification is required by 10CFR5O,72(b)(2)(X). This CR was submitted at 0716 on 05412-2009. Sample well T3 Is inthe yam at the NE corner of the lHNP-I Turbine Building. Ed Burkett, 05-12-2009.

Whet Is effected.

Proper montoring groundwaftr for tritium activity per Chemistry procedure.

"[The licensee was] notified by Southern Nuclear Company (SNC) Chemistry that, while performing [the procedure for monitoring) the tritium activity results for ground water sample well number T3, elevated tritium levels were detected.

"On May 5, 2009, [a] data report from Georgia Power Central (GPC) Lab containing tritium activity results for ground water sample well T3 was received and reviewed for input into (the] Chemistry database. [The] activity for well T3 was observed to be elevated (36,500 pCilL). This concentration had increased from [the] last sample activity (5400 pCl/L) on March 16, 2009. Chemistry personnel were directed to resample for verification [of the elevated activity levels]. A sample was collected on May 6, 2009 and shipped to GPC Lab. Sample results for the verification sample were received May 11, 2009. These results were confirmed to be elevated (34,300 pCi/L) compared to previous levels. Chemistry Management has notified the resident NRC inspector as well as SNC environmental affairs. SNC Corporate is performing the necessary notifications to the Georgia State Environmental Protection Division (EPD)."

The licensee is developing a plan to ascertain the cause of this event.
