At 0135 EDT on 07/12 both Startup Transformers "SA" and "SB" were deenergized due to the loss of the 34.5kV power distribution lines (offsite power). The licensee declared an Unusual Event at 0148 EDT based on the loss of power to both transformers for greater than 15 minutes (EAL MU1).
As a result of the loss of offsite power, the Unit automatically scrammed with all control rods fully inserting. Both Emergency Diesel Generators EDG #1 and EDG #2 auto started and are carrying vital loads. The Unit is stable in Hot Shutdown with decay heat removal via the Isolation Condenser. The licensee reported that the transient may be due to a possible lightning strike caused by adverse weather.
The licensee informed the NJ State Police and the NRC Resident Inspector.

At 0405 EDT on 07/12 the licensee terminated the Unusual Event based on restoration of offsite power and reenergizing both Startup Transformers.
The licensee informed the NJ State Police and the NRC Resident Inspector. Notified R1 (Lew), EO (Holian), IRD (Gott), FEMA (Austin) and DHS (Inzer).

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text LOST AMERICIUM-241 SOURCES DUE TO AIRCRAFT CRASH
On June 22, 2009, an F-16 crashed in a remote area in the Great Salt Lake test range in the area of the Utah and Nevada borders near Hill AFB. The aircraft was carrying a Sniper Laser Targeting Pod with two Am-241 sources each with an activity of 4 microcuries (8 microcuries total). Following investigation of the crash site and aircraft remnants, the licensee has determined that the sources are lost. The licensee has previously notified NRC Region IV (Browder) of this occurrence.
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.
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

"On 07/13/2009 at 00:38 EDT a planned manual reactor trip was initiated on Unit 2 based on increased, unidentified RCS leakage. The RCS leakage had increased over a four day period. The downpower was initiated at 21:32 EDT from 100% power and proceeded in a controlled manner to 25% power. The reactor was manually tripped at 00:38 EDT, as planned. Following the reactor trip, EOP-1, Standard Post Trip Actions, and EOP-2, Reactor Trip Recovery procedures were completed and the unit was stabilized in Mode 3. Decay heat was removed by the Steam Bypass Control System (SBCS) to the condenser. The Main Feedwater Pump unexpectedly tripped on low suction pressure just prior to the reactor trip, but was recovered prior to levels reaching the Auxiliary Feedwater Actuation (AFAS) setpoint. There were no further major equipment failures identified post trip.
"On 7/13/2009 at 07:00 EDT a Containment walkdown confirmed the leak was caused by a J-joint weld defect on the 2B2 RCP Seal injection line. The leak is classified as reactor coolant pressure boundary leakage.
"The plant is in the process of cooling down to enter Mode 5 as required by Technical Specification 3.4.6.2.a.
"This non-emergency notification is being made pursuant to 10 CFR 50.72(b)(3)(ii)(A). Additional investigation is being performed to determine the cause of the leak."
The initial leak rate was less than 0.2 gpm. The repair will require taking the plant to a reduced inventory.
The licensee notified the NRC Resident Inspector |

"At 2200 CDT on 7/13/09 it was discovered the Emergency Notification System (ENS) phone lines in the Unit 1 and Unit 2 control rooms and the Technical Support Center were not functioning. Additionally, the Health Physics Network is not functioning. This discovery occurred during extent of condition troubleshooting when it was determined that local cellular phone and land-line phone service was unavailable in some local areas. A successful land-line phone call to the NRC Operations Center was completed following this discovery, All State and local authorities required to be contacted in the event of an Emergency Class declaration were contacted via land-lines and made aware of the situation.
"Also at this time, the Dedicated Emergency Fax/Voice System (DEF/VS) is unable to fax to the Arkansas Department of Health (ADH) Little Rock Operations Center. Land-line voice communications to Little Rock have been verified. The Russellville ADH office is able to receive fax notifications from ANO and can ensure that all state and local agencies can be notified. The Russellville ADH office will remain manned until the situation is resolved.
"At approximately 2345 CDT, it was determined that the NRC Operations Center was unable to directly contact either Unit 1 or Unit 2 control room.
"The cause of the loss of communications is suspected to be a major fiber-optic line being cut In Morrilton, Arkansas. No estimate of time for repairs Is available at this time."
The licensee has established that communication capability exists via either radio or phone with local emergency response and law enforcement organizations. The licensee can still contact the NRC via commercial circuits but cannot receive calls from the NRC. A dedicated cell phone line has been established by the licensee to facilitate communication from the NRC if necessary.
State and local authorities have been informed of the problem. The NRC Senior Resident Inspector has been notified and has responded to the site.
* * * UPDATE BY HUFFMAN AT 0500 EDT ON 7/14/09 * * *
The ENS lines and commercial phone service have been restored to ANO and verified operable. R4DO (Gaddy) notified. | |
