21.21(a)(2) - INTERIM EVAL OF DEVIATION
| Person (Organization):
GEORGE HOPPER (R2DO)
NRR PART 21 GROUP (EMAI)
| Event Text INTERIM REPORT CONCERNING BATTERY CELLS WITH POTENTIALLY REDUCED DISCHARGE CAPACITY
"This letter will serve as the interim report to the Commission as pursuant to 10CFR21.21 (a) (2). The notification is in regards to a 2GN-23 battery manufactured by EnerSys and installed as part of Station Battery 2-2 at the Dominion Virginia Power, North Anna Station. Battery verification testing performed at North Anna indicated that although the battery was able to meet North Anna's 2 hour discharge requirements, cell #59 appeared to show reduced capacity. As a result, Dominion returned cells #59 and #60 to EnerSys. The cells were received at the EnerSys Corporate Laboratory under Return for Analysis (RFA) ENS-11204.
"During our analysis, which consisted of float charging, discharge testing at the 3 hour rate and an internal inspection it was determined that the cell was unable to meet the defined technical requirements for discharge capacity. Following the determination a series of analytical tests were ordered to perform more in depth analyses of the internal components. Testing on the component samples is currently underway. At this time we have not yet been able to determine if a "defect" as defined in Part 21 exists and therefore this interim report has been prepared. It is expected that the current tests will be completed by May 11, 2012. However, it should be noted that further analysis including the return of additional cells may be required to determine the cause and the reportability under Part 21 reporting."
"Throughout the return and analysis processes EnerSys has been in contact with representatives of the North Anna Station. They have been made aware of the electrical test results and recently of the internal inspection results. They are also aware that there has been no cause determination at this time. Station personnel have also been notified that this interim report has been issued."
* * * RETRACTION FROM WILLIAM ROSS TO HOWIE CROUCH AT 0953 EDT ON 5/11/12 * * *
The following information was received from EnerSys via fax:
"Subsequent to the March 12th letter, analytical testing on the components of the returned cells was completed. The results indicated there were no material composition discrepancies or assembly process anomalies. The only issue seen in cell #59 was that a portion of the positive active material physically separated from the positive grid structure. Additionally, data recorded during the manufacturing process was reviewed with no issues or nonconformities noted.
"A visit to the North Anna site was undertaken by EnerSys Engineering to review information from both Station 1 and Station 2. Battery verification testing at both stations showed all station batteries to have acceptable performance. A comparison of the testing performed by North Anna and the testing performed by EnerSys indicated that there was no further capacity degradation in cell #59. It is expected that the cells in the two station batteries will perform similarly.
"Based upon our further investigation we have concluded that no deviation per 10CFR21.21 exists. The positive active material separation was determined to be to a unique inconsistency in that plate curing lot."

| Event Text AGREEMENT STATE REPORT - MOISTURE DENSITY GAUGE DAMAGED AT JOBSITE
The State of Texas supplied the following information via email:
"The RSO for Rone Engineering contacted the Texas Radiation Program by phone on 4 May 2012 at approximately 10:15 AM CDT. The RSO reported a gauge had been damaged when run over by a water truck on a highway construction site in San Antonio. The RSO requested a radiation program inspector to conduct a radiation survey of the device because there was no radiation detection equipment immediately available.
"An inspector was dispatched to the site and reported that the device was severely damaged, but the radioactive sources were still shielded. However, the source rod was broken and radiation levels at the point where it broke were measured to be 86 millirem per hour. The licensee contacted a company licensed to recover and ship radioactive sources. The recovery company packaged the gauge and will return it to the manufacturer.
"The gauge was a Troxler 3430 plus, Serial number 60001. The gauge contained two sources; one 0.696 GBq Cs-137 and one 1.48 GBq Am-241 The Cs-137 source serial number was 77-7272 and the Am-241 source serial number was 78-4445."

"On May 11, 2012, a failure of the High Power Feed Regulating Valve FCV-9011 resulted in '2A' S/G water level lowering. Manual operator control of the Main Feed Regulating system was unsuccessful in stabilizing S/G water level. '2A' S/G level lowered to the procedurally required manual reactor trip criteria. The crew inserted a manual trip. All CEAs fully inserted into the core. Following the trip, Auxiliary Feedwater actuated as designed and decay heat removal was via Auxiliary Feedwater and Steam Bypass to the Main Condenser. All equipment operated as expected. Currently, Unit 2 is maintaining pressurizer pressure at 2250 psia, temperature at 532 degrees F on Main Feedwater (using Low Power Feed Regulating Valves LCV-9005/9006) and Steam Bypass Control.
'Unit 1 was unaffected and remains in Mode 1 at 29% power.
"This event is reportable pursuant to 10CFR50.72(b)(2)(iv)(B) for the Reactor Trip, as well as 10CFR50.72(b)(3)(iv)(A) for specified system actuation (Auxiliary Feedwater)."

"At approximately 0515 EDT today, Seabrook experienced a brief loss of the Emergency Notification System (ENS). The ENS was inoperable for approximately four minutes due to an unknown cause. During this time, commercial telephone lines were available as a means of communication with the NRC. A subsequent communications check using the ENS phone was satisfactory.
"This event is being reported as an eight-hour notification in accordance with 10CFR50.72(b)(3)(xiii) for a loss of offsite ENS communications capability. Investigation into the cause continues and will be documented via the corrective action process."

"At 16:03 hours on 5/11/12, Susquehanna Steam Electric Station Unit 2 entered LCO 3.0.3 due to two control room floor cooling systems being inoperable.
"A discharge damper for the 'A' train of control room floor cooling had failed earlier during the same day at 05:23 hours, rendering the associated 'A' fan inoperable. The redundant 'B' train fans and associated Control Structure Chiller automatically started as a result of a fan low flow interlock. The 'A' train logic was left in 'Start' and the 'B' train logic was left in 'Auto' as directed by an alarm response procedure.
"During application of a clearance order for repair of the failed 'A' fan damper, the 'A' control room cooling fan switch was placed in 'Stop' position. This resulted in an automatic start of the 'A' Control Structure Chiller and all the associated 'A' fans except for the control room cooling fan, and a trip of the 'B' train fans and chiller. This condition caused a loss of both control room cooling fans.
"The control room operators immediately recognized the loss of cooling and took manual action to restart the 'B' train.
"LCO 3.0.3 was exited at 16:18 hours without a reactor power reduction. This condition is reportable as loss of entire safety function under 10CFR50.72(b)(3)(v) & (vi)."
