| Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text HPCI INOPERABLE DUE TO LEVEL SWITCH FAILURE
"On 11/28/2007 at 0230 CST, Browns Ferry Unit 1 received a 'HPCI PUMP SUCT HDR LEVEL LOW' alarm and HPCI automatically transferred its suction from the Condensate Storage Tank (CST) to the Suppression Pool. With the HPCI suction not aligned to its normal source, the HPCI system was declared inoperable. At 0710 CST, trouble shooting identified a level switch malfunction. This switch was removed from service allowing HPCl to be returned to the normal Standby Readiness configuration. The System was declared Operable at 0710 when the system was aligned back to normal suction source.
"This event is reportable under 10CFR 50.72(b)(3)(v)(B) '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: Remove Residual Heat' and 10CFR 50.72(b)(3)(v)(D) '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: mitigate the consequences of an accident.'
"This event also requires a 60 day written report in accordance with 10CFR 50.73(a)(2)(v)(B) and 10CFR 50.73(a)(2)(v)(D)."
The licensee notified the NRC Resident Inspector.

"ENS Event Number 43809, made on 11/28/2007, is being retracted.
"NRC Notification 43809 was conservatively made to ensure that the eight-hour non-emergency reporting requirements of 10 CFR 50.72 were met pending the evaluation of an atypical system alignment with the High Pressure Coolant Injection (HPCI) [system].
"An evaluation has been performed in response to this event. The evaluation concluded that the HPCI system was capable of performing its intended safety function in this atypical configuration. As such, the circumstances discussed in the report did not result in any condition that could have prevented the fulfillment of the safety function of structures or systems needed to mitigate the consequences of an accident. Thus there would have no impact on nuclear safety. Therefore, this event is not reportable under 10 CFR 50.72(b)(3)(v)(B) or 10 CFR 50.72(b)(3)(v)(D).
"TVA's evaluation of this event is documented in the corrective action program.
"The licensee has notified the NRC Resident Inspector."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE
The State provided the following information via email:
"At approximately 11:30 AM January 23, 2008, the Agency was informed that the Licensee had a Instro Tek Model 3500, SN 599, portable moisture/density gauge stolen from the back of a truck. The theft occurred at approximately 6:00 AM . The gauge was locked with a chain in the bed of the truck which was parked unattended at an employee's residence. The gauge contains 11 mCi (408 MBq) of Cesium-137 and 44 mCi (1.63 GBq) Am:Be-241. The Licensee is offering a $500.00 reward for the recovery of the source. A press release will be made.
"Glendale PD is investigating and has issued report number 08-8332.
"The Agency [State] continues to investigate the circumstances regarding this theft for the source. The states of CA, NV, CO, UT, and NM and Mexico and U.S. NRC and FBI are being notified of this event."
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. |

"On January 25, 2008, at about 0902 PST, SCE notified the City of Dana Point Emergency and Support Services of a spurious actuation of a SONGS [San Onofre Nuclear Generating Station] emergency response siren located in the City of Dana Point.
"The actuation occurred on January 25, 2008 at about 0900 PST with a duration of approximately ten seconds. The cause of the actuation appears to be due to SCE [Southern California Edison] maintenance being performed at the time.
"SCE personnel notified Orange County and the State of California Office of Emergency Services regarding the inadvertent actuation of part of the public notification system.
"In compliance with 10CFR50.72(b)(2)(xi), requiring licensees to report any event that results in notification to other government agencies, SCE is providing this notification to the NRC.
"At the time of this occurrence, Unit 2 was operating at about 96 percent power and Unit 3 was operating at about 100 percent power. SCE has notified the NRC resident inspectors about this occurrence and will provide them with a copy of this report." |

"At approximately 1300 hours Eastern Standard Time on Friday, January 25, 2008, the Cook Nuclear Plant (CNP) determined that under certain accident conditions, the Technical Support Center (TSC) may become uninhabitable due to the inability to switch to the emergency ventilation mode.
"Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room if necessary based upon results of procedurally required monitoring of TSC radiological conditions.
"Parts are available and repairs are expected to be completed during the current shift.
"This event is reportable as specified in NUREG 1022 as a loss of an emergency response facility in accordance with 10 CFR 50.72 (b)(3)(xiii)."
