At 1505 hrs. on Friday August 29, 2003, TM … At 1505 hrs. on Friday August 29, 2003, TMI Unit 1 determined that there had been a degradation of the emergency preparedness response capabilities when there was a loss of the Emergency Notification System (ENS), the Health Physics Network (HPN) and the Emergency Response Data System (ERDS). In addition most site telephone lines were inoperable. The loss of these communications systems was most probably caused by a lightning strike. Limited telephonic communications remains with the TMI 1 control room, i.e., one commercial phone exchange, a satellite phone and the emergency management phone circuit remain operable.</br>TMI 1 has verified operability of the ERO notification system (pagers), and the communication circuit used to notify the state and local counties. The siren system for local counties was unaffected by loss of site telephone systems. Plant page and radio systems remain operable. Adequate communications capabilities are operable at this time to implement the emergency plan. </br>Repairs to restore the inoperable telephone systems are in progress at this time. A return to service time for all systems is to be determined. However, at the time of this report, the ENS line has been restored to an operable </br>status.</br>TMI 1 has determined that this event is reportable to the NRC as an 8-hour non-emergency report in accordance with 10 CFR 50.72 (b)(3)(xiii).</br>The NRC Resident Inspector, the State of Pennsylvania, and local authorities have been notified by the licensee.</br>* * * UPDATE ON 8/30/03 AT 0448 BY DAVID WILSON TO GERRY WAIG * * *</br>The licensee reported that the Emergency Notification System (ENS) was restored to service on 8/29/03 at approximately 2100 hours EDT and the Emergency Response Data System (ERDS) was returned to service on 8/29/03 at 2212 hours EDT.</br>Notified R1DO (James Trapp).12 hours EDT.
