POTENTIAL FOR AERIAL LIFT TO IMPACT SERVICE WATER PIPING DURING SEISMIC EVENT

"At 1612 on 3/19/12 it was identified that an aerial lift was located in the Auxiliary Building stored in a seismic storage area near Train A and Train B safety related service water piping to Control Room Air Conditioning (CRAC) Alternate Cooling System. This resulted in both trains of Service Water being INOPERABLE per TS 3.7.8 and both trains of CRAC Alternate Cooling system per TS 3.7.11.

"At this time, there is no conclusive information that would support the OPERABILITY of the Service Water System during a seismic event therefore this event is being conservatively reported under 50.72(b)(3)(ii)(B), 'The nuclear plant being in an unanalyzed condition that significantly degrades plant safety.' and 50.72(b)(3)(v)(A) and (D) 'Any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structure systems that are needed for: (A) shutdown the reactor and maintain it in a safe shutdown condition, (D) mitigate the consequences of an accident.'

"The aerial lift was removed and the plant is no longer in the condition noted above."

The NRC Resident Inspector has been informed.


* * * RETRACTION FROM JACK GADZALA TO DONALD NORWOOD AT 1130 EDT ON 3/21/2012 * * *

"On March 19, 2012, EN #47755 provided notification that both service water trains were potentially inoperable based on the potential for an improperly stored aerial lift to tip onto the adjacent service water piping during a seismic event. The notification was conservatively made due to the lack of conclusive information regarding any potential interaction between the aerial lift and the service water piping during a seismic event.

"Subsequent investigation and analysis determined that physical characteristics of the aerial lift are such that it would not have adversely interacted with the service water piping.

"Therefore, both service water trains remained operable and this condition did not meet the reportability criteria identified in 10CFR50.72.

"As a result, the notification made on 3/19/2012 (EN #47755) is hereby retracted. The NRC Resident Inspector has been notified."

Notified R3DO (Stone).

OFFSITE NOTIFICATION TO STATE AND LOCAL AGENCIES DUE TO NPDES DISCHARGE

"The following ENS is being submitted late.

"On Monday, March 19, 2012 at 3 a.m. a manhole overflowed during a scheduled and permitted radiological release through the cooling tower blow down outfall. As a result, several thousand gallons of water overflowed briefly, formed puddles in the area, and was discharged through a different National Pollutant Discharge Elimination System (NPDES) permitted outfall.

"The overflow was terminated, water samples were collected from the impacted areas, and the area was remediated in keeping with the Station's environmental monitoring program. Several samples showed increased levels of tritium that were well below permitted Commonwealth and Federal effluent limits.

"There were no public health risks associated with this event. The NRC Resident Inspector was notified, and courtesy notifications were made to all appropriate government agencies and local stakeholders in accordance with NEI 07-07, Industry Groundwater Protection Initiative, on March 20, 2012. Due to notification of government agencies, this event is being reported under 10CFR50.72 (b)(2)(xi)."

The licensee informed the Commonwealth of Pennsylvania, and Berks, Montgomery and Chester counties.

LOSS PUBLIC PROMPT NOTIFICATION CAPABILITY

"At approximately 0119 CDT on 3/19/12, Cooper Nuclear Station was informed by the National Weather Service that the Shubert radio transmission tower was not working. This affects the tone alert radios Cooper Nuclear Station provides to members of the public to notify them of an emergency condition. This is considered to be a major loss of the Public Prompt Notification System capability, and is reportable under 10CFR50.72(b)(3)(xiii).

"Local county authorities within the 10 mile EPZ have been notified of the condition of the Shubert radio transmission tower and the affect on this tone alert radios and will utilize Local Route Notification (backup notification method.)

"At approximately 0635 CDT, the National Weather Service reported that the Shubert radio transmission tower had been restored and tested satisfactorily."

The licensee has notified the NRC Resident Inspector and local authorities of the condition.

TECHNICAL SUPPORT CENTER VENTILATION OUT OF SERVICE

"On March 19th 2012 at 1300, Limerick Generating Station will be performing routine preventative maintenance on the Charcoal Adsorber and HEPA Filter associated with the on-site Technical Support Center (TSC) Emergency Ventilation system. While performing this maintenance, the TSC Emergency Ventilation system will not be available to be restored within the time period required to staff and activate the TSC Emergency Response Organization (ERO).

"This work is expected to be completed by 3/19/12. If an emergency is declared requiring TSC ERO activation, the TSC will be staffed and activated using emergency planning procedures unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of TSC staff becomes necessary, the Station Emergency Director will relocate the staff to an alternate TSC location in accordance with applicable procedures.

"This notification is being made in accordance with 10CFR50.72(b)(3)(xiii) due to the loss of an Emergency Facility because of the planned unavailability of the TSC Emergency Ventilation system. The NRC Resident Inspector has been informed."

The TSC ventilation is expected to be out of service for approximately four hours.

The licensee notified the NRC Resident Inspector.

* * * UPDATE ON 3/20/12 AT 0019 EDT FROM WEISSINGER TO HUFFMAN * * *

The TSC emergency ventilation system has been returned to a normal status. The licensee will notify the NRC Resident Inspector. R1DO (Schmidt) notified.
