HYDRAZINE SPILL ONSITE

"On February 11, 2011 at 1312 hours, a notification was made to the New Jersey Department of Environmental Protection of a spill of approximately 5 gallons of steam/water solution containing hydrazine with a concentration of 30ppb which was not cleaned up within 24 hours of identification. The spill due to a steam leak on the Unit 2 Main Steam System, was identified on February 9, 2011. The solution was spilled onto a gravel substrate next to the Unit 2 Main Steam mixing bottle. The closest storm drain leading to the Delaware river was sampled and had no detectable levels of hydrazine. Leak isolation and spill containment/cleanup are in progress.

"There was no out-of-service safety related equipment that contributed to this event. No one was injured as a result of this event."

The licensee notified the NRC Resident Inspector and Lower Alloways Creek Township.

* * * RETRACTION FROM JACK OSBORNE TO PETE SNYDER AT 1753 ON 2/11/11 * * *

As a correction to the earlier information: the subject spill was cleaned up within 24 hours and is therefore not reportable.

Notified R1DO (Bellamy).

UNUSUAL EVENT DECLARED BASED ON FIRE ALARM IN DRYWELL

"At 1438 CST on 02/11/2011 a fire detector alarm was received for Recirculation Pump B in the Reactor Building Drywall. At 1453 CST the main control room was unable to determine the alarm was invalid. At this time the condition was met for EAL HU4 for a Fire within the Protected Area boundary that is not extinguished within 15 minutes of detection. At 1507 CST a Notification of an Unusual Event was declared. The alarm was verified to be invalid following visual inspection at 1513 CST. All Drywall parameters and operation of Recirculation Pump B verified to be normal. "

The licensee has notified State and local authorities as well as the NRC Resident Inspector. No media or press release is planned.

* * * UPDATE AT 1734 EST ON 2/11/11 FROM POLAN TO HUFFMAN * * *

At 1552 CST River Bend terminated the Notification of an Unusual Event following confirmation that no fire existed. The licensee has notified the NRC Resident Inspector. R4DO (Clark) and NRR EO (Hiland) notified. DHS (Inzer) and FEMA (Canupp) informed.

OFFSITE NOTIFICATION OF A SEWAGE SPILL CONTAINED ONSITE

The site Environmental Protection (EP) group notified the control room of a 3000 gallon sewage spill from the Mesa Sewage Treatment Plant. The spill overflowed to the storm water catch basin. The EP group notified the San Diego Regional Water Quality Board and the San Diego Department of Environmental Health. All sewage has been contained within the storm water catch basin. EP is currently on station to remediate the sewage spill. No sewage has been discharged offsite.

The licensee has notified the NRC Resident Inspector.

INOPERABLE CONTAINMENT ISOLATION DAMPERS

"On February 11, 2011 at 0327 [CST], Secondary Containment isolation damper V-D-61 (Reactor Building Outboard Isolation Damper) was discovered iced closed with the actuator broken. The corresponding inboard damper, V-D-62, was found blocked partially open due to icing. Technical Specification Condition 3.6.4.2.B was entered for one Secondary Containment penetration flow path with two isolation valves inoperable. This resulted in a condition which could have prevented the fulfillment of a safety function required to control the release of radioactive material and mitigate the consequences of an accident. The required action to isolate the flow path by use of one closed and de-activated valve was completed at 0354 [CST], within the four hour completion time. Repair activities are in progress."

The licensee notified the NRC Resident Inspector and the State of Minnesota Duty Officer.

TEARS DISCOVERED IN FLEXIBLE PIPE SEALS

"On February 11, 2011, during a plant walk down, it was discovered that two flexible boots sealing two piping penetrations in the secondary containment boundary had a total of three small tears rendering them inoperable.

"Technical Specification 3.6.6.2, 'Secondary Containment,' is applicable in Modes 1, 2, 3, and 4 and was entered. Since Secondary Containment was rendered inoperable, Dominion is reporting that this condition could have prevented the fulfillment of the safety function to control the release of radioactive material. Further engineering review will be conducted to more fully evaluate the impact on radiological controls."

No actual release occurred as a result of this condition.

The licensee notified the NRC Resident Inspector, the State of Connecticut and the Town of Waterford.


* * * RETRACTION FROM ROBERT ACQUARO TO DONALD NORWOOD AT 1503 EDT ON 3/21/2011 * * *

"On February 11, 2011, small tears were discovered on flexible boots sealing two piping penetrations in the secondary containment boundary on Millstone Power Station Unit 3. Operators made a report in accordance with 10CFR50.72(b)(3)(v)(C).

"Subsequently, an engineering evaluation has been completed that concludes that the discovered tears would not have prevented the fulfillment of the safety function of the secondary containment boundary. Therefore, the condition reported in event report 46607 is being retracted.

"The NRC Senior Resident Inspector has been notified."
