PLANT HAD AUTO REACTOR SCRAM FROM 100% POWER DUE TO LOW REACTOR WATER LEVEL AS RESULT OF A PARTIAL LOSS OF OFFSITE POWER

"At 2041 hrs on 09/19/03, an electrical fault on 500 KV Bus Section 2 caused a Group A Transformer lockout. The Alpha and Charlie 4.16 KV vital busses did not transfer to their respective alternate infeeds from Group B Transformers, the associated Emergency Diesel Generators auto-started to supply their respective busses, and the associated Loss of Power sequencers initiated. This automatic electrical transfer caused a loss of the Alpha and Charlie Reactor Feedpumps due to a low hydraulic oil pressure signal, and Reactor level decreased to the low level RPS scram setpoint of 12.5 inches. All rods fully inserted in response to the RPS scram signal. Reactor water level dropped to approx. minus 25 inches and was subsequently returned to a normal level of 34 inches post-scram by the Bravo Reactor Feedpump. In addition, 7.2 KV Bus 10A110 failed to transfer to its alternate infeed breaker, and de-energized causing a loss of the Alpha and Delta Turbine Building Chillers, 00K107 Station Air Compressor, Alpha Primary Condensate Pump, Alpha Secondary Condensate Pump, and the Alpha Reactor Recirc Pump. The Alpha Fuel Pool Cooling and Cleanup Pump tripped during the electrical transient, and was subsequently restarted. The Alpha and Bravo Reactor Water Cleanup Pumps tripped during the electrical transient, and preparations are being made to restart the system. Core circulation is being supplied by the Bravo Reactor Recirc Pump. Reactor Pressure is being controlled by Turbine Bypass valves to the Main Condenser, and Reactor Pressure is 762 PSIG. Electrical Distribution personnel are inspecting Switchyard electrical components and relaying to determine the exact location and nature of the fault. Hope Creek-Salem 500 KV 5037 500 KV line has been isolated as a result of visual reports of arcing/tracking, and is considered a potential cause of the electrical transient. Forced outage team personnel have been assembled to review the event and develop a recovery plan. This event is being reported IAW 10CFR50.72(b)(2)(iv)(B) for the actuation of RPS on a low reactor water level signal and 10CFR50.72(b)(3)(iv)(A) due to the Emergency Diesel Generators start and sequencer initiation,"

Two (A&C) of four Emergency Diesels started and loaded to their busses. The B&D Emergency Diesels are available. The plant has two offsite power sources available, but only one is feeding the B&D vital busses.


The NRC Resident Inspector was notified.

"Salem Unit 1, Unit 2, and Hope Creek Shut Down.

"After riding out Hurricane Isabel and supplying power to the PJM grid, Salem Units 1 and 2, and Hope Creek were shut down over the weekend due to salting in the switchyard.

"High winds and rough surf in the Delaware River resulted in salt deposits in the 500 KV switchyards at Salem and Hope Creek. These deposits caused electrical faults and arcing in both switchyards. Hope Creek automatically shut down on Friday at 8:41 p.m. due to problems initiated by the switchyard. Salem Unit 1 and Unit 2 were manually taken off line Saturday morning at 3:44 a.m. and 4:37 a.m. respectively.

"A team has been assembled to investigate the cause of the events. All three units will remain shutdown while the switchyards are cleaned and any necessary repairs are made. The cleaning of the salt from the switchyards has already begun."

BOTH HOPE CREEK AND SALEM LOST ALL METEOROLOGICAL CAPABILITY

This notification is for both Hope Creek and Salem stations pursuant to 10CFR50.72(b)(3)(xiii) as a major loss of emergency assessment capability, offsite response capability, or offsite communication capability; specifically, the loss of all meteorological data for Hope Creek and Salem stations. Meteorological data is supplied to both stations via a common communications lank. Data is transmitted to Hope Creek then relayed to Salem. The problem in the communication link has been isolated to a faulty computer, which supplies Hope Creek with data. Troubleshooting and repairs are in progress; a projected availability time is not yet available.

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.
Hi all
Currently, all 3 nukes are shutdown due to problems resulting from Hurricane Isabel.
Here's what was reported on the NRC website for Monday:


"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.
