PIPING LEAK ISOLATED ON HIGH PRESSURE COOLANT INJECTION

"On 06/26/11, at 0030 [hrs. EDT], Peach Bottom Atomic Power Station Unit 3 declared the High Pressure Coolant Injection [HPCI] system inoperable for an ASME class 2 exempt piping leak found during operator rounds. Piping on the steam line pressure indication sensing line downstream of a sensing line root valve had an approximate 5 drop per minute leak. The leak has been isolated and the Unit 3 HPCI system was restored to an operable condition as of 0347 on 06/26/11.

"This report is being submitted pursuant to 10CFR 50.72(b)(3)(v)(D)."

The licensee notified the NRC Resident Inspector.

* * * RETRACTION ON 08/08/2011 AT 1432 EDT FROM DAVE FOSS TO RYAN ALEXANDER * * *

"The purpose of this notification is to retract a previous report made on 06/26/11 at 0525 [EDT] (EN# 46987). Notification of this event to the NRC was initially made as a result of declaring the Unit 3 High Pressure Coolant Injection (HPCI) system inoperable on 06/26/11 at 0030 [EDT] when a small leak on an instrument sensing line was found during performance of routine operator rounds. Specifically, it was observed that the 1/2 inch instrument piping for the non-safety related HPCI steam supply pressure indicator was leaking at approximately 5 drops per minute. The location of the leak was downstream of the instrument line root valve. The leak was isolated and the Unit 3 HPCI system was considered operable at approximately 0347 [EDT] on 06/26/11. The ENS report on 06/26/11 was originally submitted to report a potential loss of safety function involving the Unit 3 HPCI system due to this leak.

"Since the initial report, engineering has determined that HPCI was capable of performing its safety function at the time the instrument sensing line was leaking. The evaluation determined that the small sensing line leak would not have resulted in any significant equipment qualification, internal flooding or other equipment concerns that could have affected the HPCI system capability during any postulated design basis events. The pressure indicating instrument supplied by the sensing line is not safety related and is not required for any HPCI function or HPCI operability. Therefore, HPCI was determined to have maintained its operability during the time period that the HPCI sensing line was leaking.

"The NRC resident has been informed of the retraction."

Notified R1DO (Powell).

AGREEMENT STATE REPORT INVOLVING AN UNDER-DOSE

The following report was received from the State of Virginia via fax:

On June 8, 2011, a prostate implant procedure was performed utilizing 57 seeds of 0.406 mCi/seed to a gland size of 33.7 cc. The intended dose was 145 Gy. On August 2nd during a post-plan evaluation, a CT was performed where it was discovered the base of the prostate was under-dosed. It is estimated that all 57 seeds are 1 cm short of the far superior position. The prescribed minimum D-90 dose was 80 Gy, a calculation was performed estimating that the actual dose delivered was 51 Gy. The physician and patient have been notified. A follow-up visit has been scheduled.

Virginia Event Report ID No.: VA-11-06

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.
