24 HOUR REPORT - VALID ACTIVATION OF A TSR REQUIRED SAFETY SYSTEM
"At 1807 CST, on 1-11-02 the Plant Shift Superintendent (PSS) was notified of an activation of the Water Inventory Control System (WICS) on #4 autoclave In the C-360 building. Approximately seven minutes into the heat cycle the Hi Primary and HI Secondary Condensate alarms were received, and the autoclave went into containment as designed. The operators investigated the alarm with assistance from the Shift Engineer. Due to the alarm being received on the redundant Primary and Secondary probes at a point in the heat cycle when there is a high steam demand. Engineering determined this to be a valid activation of the system. The autoclave was removed from service and the WICS was declared inoperable. Further investigation will be performed by the System Engineer and Instrument Maintenance to determine the exact cause of the alarm. The purpose of the WICS is to limit the amount of water In the autoclave and is a safety system required by TSR 2.1.4.3.
"The PSS determined that this event is a 24 Hour Event Report due to the valid activation of a TSR required safety system.
"The NRC Senior Resident Inspector has been notified of this event."
* * * UPDATE ON 1/30/02 @ 1357 BY BEASLEY TO GOULD * * * RETRACTION
UPDATE 1-30-02: THIS EVENT HAS BEEN RETRACTED. Subsequent troubleshooting and analysis, led by the system engineer concluded that the WICS activation was initiated by an invalid signal (electrical short), and therefore the reporting criteria is not met. During troubleshooting It was discovered that the shielding on the primary probe's wire connector was worn. This allowed the wire to come into contact with the side of the connector causing it to short and actuate the WICS alarm.
The NRC Senior Resident Inspector has been notified of this event.

TECHNICAL SPECIFICATION SHUTDOWN DUE TO # 2A EMERGENCY DIESEL GENERATOR NOT OPERATING PROPERLY.
"A unit shutdown was initiated at 0400 on 01/11/02 as required by Technical Specifications. Technical Specification Action Statement 3.8.1.1.b action b was entered at 0303 on 01/08/02 for scheduled maintenance on the 2A emergency diesel generator. During post maintenance testing, oscillations associated with the generator voltage control system were observed. The cause of the voltage oscillations has not been identified or corrected. Troubleshooting activities are on-going in an attempt to identify the cause.
"The 2B and 2C emergency diesel generator surveillance tests were performed within 24 hours to evaluate for common cause failures. A Common Cause Failure was not identified and the 2B and 2C surveillance tests were performed satisfactorily.
"Salem Unit Two will be in Mode 3 by 0930 on 01/11/02 and in Mode 5 by 1503 on 01/12/02 as required by Technical Specifications.
"Salem Unit one is not affected by this event and remains in Mode 1 at 100%"

OFF-SITE SIRENS INOPERABLE IN YORK COUNTY
"TMI is notifying the NRC Operations Center in accordance with 10 CFR 50.72(b)(3)(xiii) that a major loss of emergency preparedness capabilities for TMI has occurred. At 9:15 AM on Friday, January 11, 2001 during a test of all of the emergency sirens for the five (5) risk counties around TMI, it was determined that the public emergency sirens for York County did not activate. Attempts to return the sirens to an operable status within 1 hour were unsuccessful. The sirens are currently inoperable.
"The apparent cause of the siren failure was a serial port failure on the computer that activates the York County signal transmitter. Therefore, no signal was transmitted to the 34 sirens for York County. Troubleshooting is in process to determine the exact cause of the failure.
"The siren test covered all of the five (5) risk counties around TMI. All of the public emergency sirens for the other four risk counties for TMI (Cumberland, Dauphin, Lancaster and Lebanon) activated with the exception of a single siren in Lancaster County. The inoperability of sirens for one-(1) of the five (5) risk counties around TMI impacts a large segment of the population. (continued on next page)
"This event meets the criteria set forth in NUREG 1022 for a major loss of emergency offsite communications capability. The site Sr. Resident Inspector has been informed of the event and the 8-hour report. The Pennsylvania Emergency Management Agency (PEMA) has been notified of the event. York County Emergency Management is aware of the event and has contacted the siren vendor. The siren failure event is being entered into the TMI-1 corrective action program."
The licensee notified the NRC Resident Inspector as well as state and local authorities.
