INTEGRATED SAFETY ANALYSIS (ISA) - UNANALYZED CONDITION

"As part of the ongoing GNF-A review of the Fuel Manufacturing Operation (FMO) Integrated Safety Analysis, accident sequences associated with hydrogen piping are being evaluated. As part of this evaluation, facility walk downs of the piping were performed that identified a configuration that had not previously been analyzed. Based on a review of this as found condition, it was determined at approximately 12 p.m. on August 12, 2011 that the system was improperly analyzed in the ISA and resulted in a failure to meet performance requirements.

"Hydrogen supply to the affected piping system inside the building has been isolated. Additional corrective actions and extent of condition are being evaluated.

"This event is being reported pursuant to the reporting requirements of 10 CFR 70 Appendix A (b)(1) within 24 hours of discovery."

The licensee will notify NRC Region 2 and appropriate state and local authorities.

* * * UPDATE FROM PHILLIP OLLIS TO ERIC SIMPSON AT 1228 EDT ON 8/24/11 * * *

"Unnecessary piping branches have been removed and caps welded in place. The new piping configuration has been analyzed for ISA accident sequences.

"Based upon this, hydrogen supplies to affected equipment will resume and normal operations will commence."

The licensee will notify NRC Region 2.

Notified R2DO (Widmann) and NMSS EO (Campbell).

AGREEMENT STATE REPORT INVOLVING A DAMAGED MOISTURE DENSITY GAUGE

The following information was obtained from the State of Texas via email:

"On August 18, 2011, the Agency [Texas Department of State Health Services] was notified that a Humboldt model 5001 EZ, serial number 4220, containing a 44 milliCurie Americium-241/Beryllium source and an 11 milliCurie Cesium-137 source was run over by a dirt compactor. The user placed the device on the ground 12 feet from his truck to perform prior to use checks on the gauge. The sources were in the fully shielded position. When the technician went to the cab of their truck to record readings, a dirt compactor came up out of a pit near the truck. The technician could not get the attention of the compactor driver in time to prevent them from driving over the gauge. The technician contacted the fire department and [informed] his manager of the event. The licensee's Radiation Safety Officer (RSO) and fire department both responded to the scene. The RSO conducted a radiation survey of the device and determined that the sources were fully shielded. A service company was contacted and they took the device to their facility. The service company performed leak tests on both sources. The results were below the regulatory limit. Additional information will be provided as it is received."

GEORGIA AGREEMENT STATE REPORT - LOST INDUSTRIAL NUCLEAR GAUGE

On 8/17/11, the licensee discovered that a nuclear process gauge was missing. The gauge was suspected to have been placed in the trash and transported to a local landfill. The landfill operators have been notified. Workers at the facility were interviewed but the licensee could not determine the disposition of the gauge.

The gauge, a BSI Instruments model NW201, serial number 1041, was last seen on or about August 4, 2011. The missing gauge, plus two others, were verified to be in temporary storage awaiting transfer to an outside organization. The gauge contained 0.5 mCi of Cs-137. The two other gauges are accounted for and stored properly.

Georgia Report #: GA2011-40I

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

CALIFORNIA AGREEMENT STATE REPORT - LEAKING IODINE-125 BRACHYTHERAPY SEEDS

The following information was obtained from the State of California via email:

"UCLA contacted the Brea office of RHB [Radiologic Health Branch] to report a leaking source of I-125 brachytherapy seeds. Initial survey of the packaging, upon receipt, did not show any contamination. Subsequent testing showed 1.8 microCuries of contamination. The order was for 19 seeds, 16 for treatment, one for calibration and 2 for spares. A physician was preparing an eye plaque using the 16 seeds. A dish of acetone was used to remove glue from the seeds. A radiation survey discovered that the dish had become contaminated with I-125. The patient's procedure was cancelled and EH&S [Environmental Health and Safety] personnel were notified about the issue. EH&S collected all 19 seeds and performed a leak test on the 16 treatment seeds by soaking them in isopropyl alcohol. The fluid was analyzed on a liquid scintillation counter which found 1.8 microCuries of removable contamination.

"Per 10 CFR 35.3067, a licensee shall file a report within 5 days if a leak test required by 35.67 reveals the presence of 185 Bq (0.005 uCi) or more of removable contamination.

"RHB is requesting UCLA to obtain copies of the leak tests performed by the manufacturer to determine if the seeds were leaking prior to being shipped to UCLA. These copies will be in the final report. If the seeds were discovered to be shipped in a compromised condition, the Virginia Division of Radiological Health will be notified since the manufacturer (Best Medical International, Inc. of Springfield, Virginia) is located within their jurisdiction."

ALERT DECLARED DUE TO AN EARTHQUAKE IN THE AREA AND A LOSS OF OFFSITE POWER

At 1403 hrs. EDT, North Anna Power Station declared an Alert due to significant seismic activity onsite. The Alert was declared under EAL HA6.1. Both units experienced automatic reactor trips from 100% power and are currently stable in Mode 3. All offsite electrical power to the site was lost. All four emergency diesel generators (EDG) automatically started and loaded and provided power to the emergency buses.

While operating, the 2H EDG developed a coolant leak and was shutdown. As a result, the licensee added EAL SA1.1 to their declaration.

All control rods inserted into the core. Decay heat is being removed via the steam dumps to atmosphere. No personnel injuries were reported.

* * * UPDATE FROM ROBERT RINK TO HOWIE CROUCH AT 1116 EDT ON 8/23/11 * * *

The licensee has downgraded the Alert to a Notification of Unusual Event based on equipment alignments and inspection results.

The licensee notified R2 IRC. Notified IRD (Marshall), NRR (Thorp), FEMA (Hollis), DHS (Inzer), USDA (Ferezan), HHS (Willis) and DOE (Parsons).

* * * UPDATE FROM ROBERT RINK TO HOWIE CROUCH AT 1317 EDT ON 8/23/11 * * *

The licensee has exited the Notification of Unusual Event at 1315 EDT. The exit criteria was that all inspections and walkdowns were completed and plant conditions no longer meet the criteria for a NOUE.

Notified R2DO (Widmann), IRD (Marshall), NRR (Thorp), FEMA (Hollis), DHS (Inzer), USDA (Ferezan), HHS (Willis) and DOE (Jackson).

CREFS WAS DECLARED INOPERABLE

"This telephone report is being made in accordance with 10 CFR 50.72(b)(3)(v) as a loss of safety function for a single train safety system. On August 23, 2011 at 15:30 CDT, the clevis pin that connects the valve with the air operator was found not fully inserted on the Control Room HVAC Emergency Bypass System Inlet Valve, HV-AO-271 AV. This valve is normally closed and opens in response to a Group 6 isolation signal to align the Control Room Emergency Filtration System) (CREFS) to outside air. A retaining clip at one end of the pin was found to be missing, allowing the pin to partially back out of the clevis. The pin was found engaged with half of the clevis. This condition resulted in declaring CREFS inoperable at 15:30 CDT, and CNS entered LCO 3.7.4 Condition A which requires the CREF system to be restored to OPERABLE status in 7 days. The cause of the displaced clevis pin is under investigation."

The licensee has notified the NRC Resident Inspector.
