On 1/14/04 a problem with emergency notifi … On 1/14/04 a problem with emergency notification sirens was identified and traced to a manufacturing defect in components supplied by Federal Signal Corporation.</br>Investigations were initiated to determine if this situation was applicable to Callaway. At 1230, 1/21/04, Federal Signal Corporation notified Callaway Plant that there was a potential for siren inoperability due to a temperature sensitive piece of equipment. It was determined that 19 out of 29 emergency sirens were subject to this potential failure if ambient temperatures fall below approximately 20 degrees F. The model number of the questionable sirens is EOWS612. Callaway conducted a "quiet test" of the questionable sirens and 4 of the sirens indicated a problem. At present the ambient temperature is above 32 degree F and it is believed that the four questionable sirens are not experiencing the temperature related failure. A field test of the four sirens is being conducted this evening to determine their operability. Alternate methods of public notification have been established.</br>The failure mechanism has been identified by the vendor and temporary repairs will begin by 1/22/04.</br>The licensee notified State and local agencies, FEMA, and the NRC Resident Inspector.</br>****Update on 01/23/04 at 1455 EST by E. Henson taken by MacKinnon****</br>This event is an update to EN# 40462 in which Callaway reported that 19 of 29 emergency sirens were potentially susceptible to temperature sensitivity. A field test of four suspect sirens was completed by 1900, 01/21/04, and it was established that all four sirens were operable. All 19 of the emergency sirens using electronic circuits that were potentially susceptible to temperature sensitivity, had temporary heating elements installed on 01/23/04, thus eliminating the temperature sensitivity problem. Federal Signal Corporation expects to have a permanent solution identified and permanent repairs completed within 3 weeks."
