BOTH EMERGENCY DIESEL GENERATORS DECLARED INOPERABLE
"At 12:00 CDT maintenance personnel identified a pinhole leak from the Division 1 Service Water System piping in the Service Water Pump Room. Division 1 Service Water [SW] was declared inoperable and LCO 3.7.2 Condition A was entered due to a potential loss of structural integrity. This directs entry into LCO 3.8.1 for Diesel Generator #1 made inoperable by SW. DG 2 was previously made inoperable at 05:39 CDT on 8/25/2012 due to an unrelated issue regarding rain water inleakage into the DG 2 Room. Control Room Emergency Filtration system [CREFs] is aligned to Div 1 power. LCO 3.7.4 Condition A is applicable, requiring restoration of CREFs to operable status within 7 days. TRM LCO 3.6.1 condition A and B also apply, requiring (A) Restoration of containment spray subsystem A to OPERABLE status within 7 days and (B) Restore one RHR containment spray subsystem to operable status within 8 hours.
"DG 1 and DG 2 comprise the onsite emergency power systems. Both DGs inoperable is reportable per 10CFR50.72(b)(3)(v)(D) as a condition that could prevent fulfillment of the safety function of structures or systems needed to mitigate the consequences of an accident.
"Actions were taken to expedite repairs of the DG 2 roof leak and to further characterize the Division 1 SW piping leak. LCO 3.8.1 Condition E allows 2 hours to restore one DG to operable status or enter Condition F, to be in Mode 3 in 12 hours, which was entered at 14:00. Repairs to the roof leak on the DG 2 room were completed, after which DG 2 was declared Operable at 18:30. LCO 3.8.1 Conditions E and F required shutdown were exited at this time. LCO 3.8.1 Condition B for DG 1, and 3.7.2 for SW Loop A, continue to be active. Planning to repair the SW piping pinhole leak is continuing. There were no adverse grid conditions during the period both DGs were inoperable.
"The NRC Resident has been informed of the condition. No media or press release is planned at this time."
* * * RETRACTION FROM FRED SCHIZAS TO DONALD NORWOOD AT 1802 EDT ON 8/31/12 * * *
"This notification is being made to retract Event Notification EN #48237 which reported a loss of safety function due to both onsite Emergency Diesel Generators (DGs) being simultaneously INOPERABLE. On 8/25/12 at 0539 CDT, DG#2 was declared INOPERABLE due to rain water in-leakage into the DG#2 room. Condition B of LCO 3.8.1 was entered. and Required Actions were being taken to restore the INOPERABLE DG within 7 days. Subsequently, on 8/27/12 at 1200 CDT Maintenance personnel identified a pinhole leak from the Division I Service Water System piping in the Service Water Pump Room. Division I Service Water was declared INOPERABLE and LCO 3.7.2 Condition A was entered due to a potential loss of structural integrity. This prompted entry into LCO 3.8.1 Conditions E and F which require shutdown, because DG#1 was made INOPERABLE by SW. Both DG's INOPERABLE is reportable per 10CFR50.72.b.3.v.D as a condition that could prevent fulfillment of a safety function of structures or systems needed to mitigate the consequences of an accident. Repairs to the roof leak on the DG#2 room were completed, after which DG#2 was declared Operable at 1830 CDT on 8/27/2012. LCO 3.8.1 Conditions E and F were exited at the time. LCO 3.8.1 Condition B for DG#1, and 3.7.2 for SW Loop A, continued to be active, and planning to repair the pin-hole leak continued.
"Subsequent investigation and UT examinations provided data which enabled SW Division 1 and DG#1 to be declared OPERABLE on 8/30/2012 at 0528 CDT. An evaluation of this condition concluded that further characterization of the SW Piping Pin-Hole leak enabled ASME Code Case N-513-3 to be applied to determine piping structural integrity was maintained. SW ability to supply required flows to its loads is not adversely diminished, because the flaw is small. Water leaking from the flaw will not adversely affect any other equipment important to safety by spray or flooding. The piping is compliant with ASME code. Based on this evaluation, the Division 1 SW system can perform its safety function and is OPERABLE.
"With Division 1 SW subsystem capable of fulfilling its safety function, DG#1 was therefore also capable of fulfilling its safety function during the period of SW subsystem INOPERABILITY. Consequently, during the period of DG#2 INOPERABILITY, DG#1 was capable of fulfilling the safety function of the onsite emergency power system. NPPD therefore retracts Event Notification EN 48237.
"The NRC Resident has been informed of this retraction."

TECHNICAL SUPPORT CENTER VENTILATION MAINTENANCE
"This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the work activity affects the functionality of an emergency response facility.
"Planned maintenance activities are being performed today (August 27, 2012) to the Technical Support Center (TSC) HVAC. The work entails removing power to system dampers rendering the TSC non-functional during the performance of this work activity. This work activity is planned to be performed and completed expeditiously within about 24 hours including establishing and removing the clearances and performing post maintenance testing.
"If an emergency condition occurs that requires activation of the TSC, plans are to utilize the TSC during the time this work activity is being performed as long as habitability conditions allow. The Emergency Response Organization duty team members will be relocated to alternate locations if required by habitability conditions in accordance with emergency implementing procedures."
The licensee notified the NRC Resident Inspector.

The TSC ventilation maintenance has been completed and the TSC was returned to service at 2005 EDT on 8/27/12.

OFFSITE NOTIFICATION DUE TO HAZARDOUS MATERIAL SPILL
"Notification was made to Missouri Department of Natural Resources and the EPA National Spill Response Center of a Neutralization Tank discharge piping leak on 8/27/12 at 1526 hrs. (CDT). Subsequent testing of the leaking fluid at 1430 hrs. revealed the pH of the leaking fluid was 13, which is a characteristic hazard waste. Reportable quantity is 100 lbs. The estimated total volume released was less than 100 gallons, but greater than 100 lbs. This spill was reported to offsite organizations. Therefore, this event is reportable to the NRC per 10CFR50.72(b)(2)(xi). Mitigating strategy is to neutralize the contents of the tank, and the leaking fluid is being absorbed by absorbent materials."
