Should an emergency be declared during this period, the Control Room will continue to have the capability to retrieve plant data inputs to assess plant conditions and perform core damage assessment at all times. Control Room Emergency Response personnel will use emergency response procedures to disseminate plant parameter data points to the effected Emergency Response Facilities until the U-2 PPC is restored. MIDAS (Meteorological Data) transmission will remain functional during the maintenance window. The Unit 2 ERDS data will not be available during the power outage from 02/27/2013 to 03/04/2013. | Should an emergency be declared during this period, the Control Room will continue to have the capability to retrieve plant data inputs to assess plant conditions and perform core damage assessment at all times.
