LOSS OF MORE THAN 20% OF OFFSITE EMERGENCY SIRENS
The following was received via fax from the licensee:
"As of 2:33 PM EDT, more than 20% of the offsite emergency sirens were inoperable for greater than one hour due to loss of power caused by Hurricane Isabel. Currently 27 of 81 sirens are out of service. The State of North Carolina and all four counties within the 10-mile emergency planning zone were notified and are in stand-by to implement mobile route alerting if needed. At this time, Harris cannot estimate the time of siren recovery. This requires an 8-hour non-emergency notification per 10CFR 50.72(b)(3)(xiii) due to the loss of a significant portion of the offsite notification system. The NRC Senior Resident Inspector was informed."
* * * UPDATE 0910 EDT ON 9/19/03 FROM JOHN CAVES TO S. SANDIN * * *
The licensee is updating this report to include that less than 20% of the emergency sirens are inoperable as of 2000 hours 9/18/03.
The licensee informed the NRC Resident Inspector. Notified R2DO(Boland).

LOSS OF EMERGENCY SIREN CAPABILITY DUE TO ADVERSE WEATHER CONDITIONS
"Due to the effects of severe weather related to Hurricane Isabel, local power outages have resulted in an excessive number of sirens within the Salem/Hope Creek 10-mile Emergency Protection Zone (EPZ) being unavailable. At 21:11 on September 18, 2003, 29 offsite sirens were unavailable (22 in Delaware and 7 located in New Jersey). As of 22:11, some sirens have been restored, but there are still 14 unavailable in Delaware and 7 unavailable in New Jersey. It is likely that the functionality of the EPZ sirens will continue to change due to the ongoing severe weather. Sirens will be recovered when power is restored.
"This notification is being for both Salem Generating Station and Hope Creek Generating Station pursuant to 10CFR50.72(b)(3)(xiii) as a major loss of emergency assessment, offsite response, or communication capability. Salem Units 1 and 2 are operating at 100% power with all safety related equipment operable.
"Hope Creek is operating at 94% power with all safety related equipment operable. Power is reduced due to the degraded performance of the non-safety related ventilation system that cools the Reactor Recirculation Pump Motor-Generator Sets."
The licensee informed the NRC Resident Inspector.
* * * UPDATEON 09/20/03 @ 1000 BY KOPCHICK TO GOULD * * *
"There are currently 11 unavailable sirens within the Salem/Hope Creek 10-mile Emergency Preparedness Zone (EPZ) (6 in New Jersey and 5 in Delaware). The current availability of sirens no longer constitutes a major loss of emergency assessment capability, offsite response capability, or offsite communication capability pursuant to 10C'FR50.72(b)(3)(xiii). It is anticipated that all sirens will be rendered available as power is restored and storm recovery actions are completed. No further updates to this event report will be provided."
The NRC Resident Inspector was informed.

UNUSUAL EVENT DECLARED DUE TO EXPECTED SEVERE WEATHER
At 0900 EDT the licensee declared an Unusual Event as a precautionary measure due to expected severe weather from hurricane Isabel. Current wind speed and direction is 10-15 mph sustained with gusting to 20 mph from the NNE direction. No additional staff other than those for the planned outage have been brought onsite.
The licensee informed state/local agencies and the NRC Resident Inspector.
* * * * UPDATE 1608 ET FROM T. HUFF TO M. RIPLEY * * * *
As of 1600 ET, Surry Unit 1 commenced a power reduction of 200 mwe (100% to approximately 75% power) in anticipation of grid instabilities due to heavy weather. One of eight circ water screens is degraded due to river debris and its associated circulating water pump has been secured. On-site meteorological panels are out of service. Additionally, the Emergency Operating Facility (EOF) is out of service due to a loss of power.
Notified R2DO (A. Boland).
* * * UPDATE 2101 EDT FROM DUANE SHEPHEARD TO NATHAN SANFILIPPO * * *
The following was received via fax from the licensee:
"With Surry Power Station Unit 1 at approximately 75% reactor power and Unit 2 at 100% reactor power, a manual reactor trip was initiated on Unit 1 at 1728 and on Unit 2 at 1732, due to the loss of the '1G' and `2G' buses which supply power to all eight circulating water pumps for both units. The loss of the buses occurred during high winds and rain associated with Hurricane Isabel, although no hurricane force winds were onsite prior to or at the time of the event. A discretionary Notification of Unusual Event had been declared earlier at 0900 due to the severe weather.
"On Unit 1, the 'B' inadequate core cooling monitor (ICCM) failed. The 'A' ICCM remained operable throughout. All control rods fully inserted and the shutdown margin for Unit 1 was determined to be satisfactory. On Unit 2, eight rod position indicators showed greater than 10 steps but less than 20 steps following the reactor trip. Emergency boration was initiated. All Unit 2 IRPIs [Individual Rod Position Indications] are currently indicating less than five steps and the shutdown margin was satisfactory.
"Auxiliary feedwater automatically initiated as designed for both units on low low steam generator level following the trip. Primary RCS temperature decreased to approximately 543 and 538 degrees on Unit 1 and 2 respectively and was stabilized at 547 degrees.
"No primary safety or relief valves were actuated during the event on either unit. As a result of the loss of the circulating water pumps, the emergency service water pumps were started to conserve intake canal level. After start, 2 out of the 3 emergency service water pumps tripped on high water temperature. The pumps were checked and restarted 14 minutes later. Also due to the need to conserve intake canal level, the main steam trip valves on both units were closed and primary temperature is being maintained by use of the secondary power operated relief valves. No indication of primary to secondary leakage exists on either unit, therefore no adverse radiological consequences resulted from this event.
"Both units are currently stable at hot shutdown. At 1845, the 2G bus was energized and circulating water pumps were started. The emergency service water pumps were secured and are in standby.
"This 4 hour and 8 hour report is being made for Surry Units 1 and 2 in accordance with 10 CFR 50.72(b)(2)(iv)(B) and 10 CFR 50.72(b)(3)(iv)(A)."
Notified R2DO (A. Boland), NRR EO (J. Calvo), DIRO (R. Wessman), FEMA (Chuck Bagwell), DHS (Colleen Wilson).
* * *UPDATE AT 1948 EDT ON 9/19/03 FROM BILL SUMMERS TO E. THOMAS* * *
The licensee terminated their unusual event due to the following conditions:
- severe weather has left the area
- both units are stable at hot shutdown on offsite power
- 2 of 3 ESW pumps are operable, and the third ESW pump is being prepared for an operational test
- 45 of 67 sirens remain inoperable, but the sirens will be restored when power to the grid is restored
The licensee will notify the NRC Senior Resident Inspector, as well as state and local officials

LOSS OF EMERGENCY SIREN CAPABILITY DUE TO ADVERSE WEATHER CONDITIONS
A significant portion of emergency sirens (43 of 72) located in Calvert, St. Mary's and Dorchester county are unavailable due to a loss of power. Restoration is not expected until dayshift when the effects of Tropical Storm Isabel have abated.
The licensee informed the NRC Resident Inspector.
