At approximately 1100 CST on Friday Novemb … At approximately 1100 CST on Friday November 16, 2007, Monticello Nuclear Generating Plant determined that there had been a degradation of the Emergency Preparedness response capabilities when the Emergency Response Data System, Offsite Dose Projection (MIDAS), Safety Data Parameter System, selected telephones, and site computer terminals became inoperable in the Technical Support Center (TSC). The loss of these systems is associated with a partial loss of power to the TSC. As a result of these conditions, the TSC was declared non-functional. Emergency Communications remain available with the Emergency Telecommunication System, and Health Physics Network being operable.</br>Monticello 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 systems. Plant page and radio systems remain operable. Adequate communications capabilities are operable at this time to implement the emergency plan. </br>The site's Emergency Operations Facility (EOF), which is the back-up facility for the TSC, is fully operational and measures are being implemented to direct TSC personnel to the near site EOF in the event of an actual emergency condition.</br>The station has informed Wright and Sherburne counties and the Minnesota State Duty Officer of this condition.</br>Troubleshooting efforts are in progress. A return to service time for all systems is to be determined. Monticello 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 licensee notified the NRC Resident Inspector.</br> * * * UPDATE FROM K. HAUGEN TO P. SNYDER AT 1253 ON 11/17/07 * * *</br>The TSC has been restored to an operable configuration.</br>The licensee notified the NRC Resident Inspector.</br>Notified R3DO (Passehl).sident Inspector.
