| Event Text PORTION OF HIGH PRESSURE FIRE WATER SYSTEM DECLARED INOPERABLE
"At 1254 CDT, on 05/15/2011, the Plant Shift Superintendent was notified that the C-333 High Pressure Fire Water (HPFW) Sprinkler System C-14 had been inspected by Fire Services and eleven sprinkler heads had visible corrosion on them. The system configuration was evaluated using EN-C-822-99-047, 'Effects of Impaired Sprinkler Heads on System Operability' and determined that with these heads potentially impaired, a portion of the building would not have sufficient sprinkler coverage. The HPFW system is required to be operable according to TSR LCO 2.4.4.5. HPFW system C-14 was declared inoperable and TSR LCO 2.4.4.5 Required Action B was implemented for the area without sprinkler coverage. Based on past testing results, there is a possibility that the heads would have been able to perform their specified safety function. Once the heads are removed from the system, testing will be performed to determine the actual affect on operability.
"This event is reportable under 10 CFR 76.120(c)(2) as an event in which equipment required by the TSR is disabled or fails to function as designed.
"The NRC Senior Resident Inspector has been notified of this event.

* * * RETRACTION FROM BILLY WALLACE TO JOE O'HARA AT 1145 EDT ON 5/20/11 * * *
"Subsequent to the event, the corroded sprinkler heads were replaced with new heads and the removed heads were tested in the laboratory. Testing by the laboratory has shown that six of the 10 removed sprinkler heads would have performed their safety function, five of the heads would not have performed their safety function, but these heads would not affect the system operability. The conclusion of the tests is that the C-333 sprinkler system C-14 would have performed its intended safety function if called upon.
"The NRC Senior Resident Inspector has been notified of this retraction."

| Event Text MEDICAL EVENT - WRONG RADIOPHARMACEUTICAL ADMINISTERED TO PATIENT
On 5/13/2011, a patient at the Lantheus Medical Imaging center was administered Indium 111 (Oxine - for labeling white blood cells) instead of Indium 111 (DTPA - for brain study), which was the prescribed radiopharmaceutical. Less than 1 milliCurie of Indium 111 (Oxine) was injected into the patient. The dose received by the patient was less than 5 Rem, and no injury was caused to the patient.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
* * * RETRACTION ON 5/17/11 AT 0939 FROM EDWARDO DIAZ TO MARK ABRAMOVITZ * * *
This event has been determined by the licensee not to be a medical event because the total dose is less than 0.05 Sv (5 Rem) required in 10CFR35.3045.

"A patient having a thyroid scan was administered 4 mCi of I-131 while in a pregnant condition. The circumstances under which the dose was administered are under investigation. The dose to the developing fetus is also under investigation. The whole body dose to the fetus is estimated to be 1 rad at this time.
"The discovery date [of 4/15/11] is an estimate. The real dose of discovery will be reported during the investigation. Also, the licensee was allowed 15 working days to issue a report to [the Massachusetts Radiation Control Program]. [The Massachusetts Radiation Control Program] received that report on May 12, 2011." |

"On 05/20/2011 at approximately 0728, an unidentified man was reported to be floating on a raft in the James River offshore of the Hog Island Wildlife Management Area. The individual had chains wrapped around his body and a suitcase and duffel bag in the raft. Station Security responded to facilitate local law enforcement actions. The individual in the raft was pulled to the shore and taken into custody. At no time was the operation of Surry Power Station threatened by the man's actions.
"The site NRC Resident Inspector has been notified.
"This notification is being transmitted in accordance with 10CFR50.72(b)(2)(xi) to ensure that the NRC is made aware of issues that may cause heightened public concern for the safety of the station."
The man was approximately a mile offshore during this incident. |

"The past operability of the 2A train of Auxiliary Feedwater has been called into question based on finding clam shells in the safety related water source piping. During performance of valve strokes on 5/9/2011 per an Operations Department surveillance, clam shells were found while draining a section of the safety related water source piping. System Engineering collected the shells as part of troubleshooting. Based on analysis performed by System Engineering, the 2A Train of Auxiliary Feedwater was not operable with clam shells in the pipe. The amount of shells present would have caused an unacceptable differential pressure across the 2A train Auxiliary Feedwater System flow control valves. The extent of condition has been evaluated for the other Auxiliary Feedwater trains for both units and it has been determined that the only affected train is 2A. The 2B Auxiliary Feedwater train has also been inoperable at various times over the past 3 years for maintenance.
"The clams were flushed out of the 2A Train Auxiliary Feedwater suction piping during a recent refueling outage and both trains of Auxiliary Feedwater on Unit 2 are operable. "
The licensee has not implemented any compensatory measures nor are they in any LCO's as a result this event.
The NRC Resident Inspector has been notified. |

"On 5/20/2011 at 2217 [CDT], while performing 1-SR-3.5.1.1(HPCI) MAINTENANCE OF FILLED HPCI DISCHARGE PIPING, operators opened 1-FCV-73-44, HPCI Injection Valve, to fill and vent portions of the system. Once open, the HPCI discharge piping rapidly pressurized to 1000 psig. Operators immediately shut the 1-FCV-73-44 valve. A flood level alarm was received in the control room and water was confirmed to have been leaking from the Gland Seal Condenser. All leakage has stopped.
"It is suspected that leakage past 1-CKV-73-45, HPCI TESTABLE CHECK VALVE, caused the rise in discharge piping pressure. An investigation into this event is ongoing.
"In accordance with TS LCO 3.6.1.3 Condition A, the affected line has been isolated by one closed and deactivated valve.
"This incident is reportable as an 8-hour ENS notification under 10CFR 50.72 (b)(3)(v) as 'any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to: d. Mitigate the consequences of an accident.'
"It also requires a 60 day written report in accordance with 10CFR 50.73(a)(2)(vii). The NRC Resident Inspector has been notified."
The volume of leakage was not specifically known but the leakage resulted in approximately 2 inches of water on the HPCI pump room floor before it was isolated. |

"At 1737 CDT on 05/22/2011, with BFN U3 [Browns Ferry Unit 3] in Mode 4, a valid RPS actuation signal was received by both channels of the RPS due to Scram Discharge Volume (SDV) High Water Level.
"At 1735, while performing IRM range 6 to 7 correlation, Instrument Maintenance technicians were measuring high voltage on IRM 'G' while reconnecting a high voltage cable. A spike occurred on IRM's 'C' and 'D' causing a full Reactor Scram. This IRM [Intermediate Range Monitor] Scram was not a valid actuation, the safety function had already been completed, and is not reportable. At 1737, after diagnosing the cause of the IRM Scram, operators reset the Scram signal and received a valid RPS Scram signal due to SDV High Water Level. Investigation is ongoing.
"This condition is reportable under 10CFR50.72(b)(3)(iv)(A) - A valid actuation of any of the systems named in 50.72(b)(3)(iv)(B).
"This is also reportable as 60 day written report IAW 10CFR 50.73(a)(2)(iv)(A).
"This event was entered into the licensee's Corrective Action Program as SR# 373366."
There are no compensatory measures or LCO's in effect for this event, and all EDG's and offsite power lines are operable. There was no increase in plant risk as a result of this event.
