| Title | Tsc Power Outage |
| Event Description | At 0647 hours0.00749 days <br />0.18 hours <br />0.00107 weeks <br />2.461835e-4 months <br />, a fault at the Conowingo Hydroelectric station resulted in the loss of the 191-00 line to Peach Bottom Atomic Power Station (PBAPS). This condition resulted in a loss of the Station Blackout (SBO) power supply for PBAPS. The Technical Support Center (TSC) facility for PBAPS is powered from the SBO power supply. Therefore, power was lost to the TSC resulting in a degradation of the emergency assessment capability at PBAPS.
Efforts were promptly initiated to restore power to the TSC. Power was restored to the TSC at 0959 hours0.0111 days <br />0.266 hours <br />0.00159 weeks <br />3.648995e-4 months <br />. The TSC Ventilation system restoration is in progress at this time. The NRC resident has been informed of this notification. |
