The expected duration of PPC inoperability is approximately 16 to 24 hours. The PPC provides monitoring and communications capability for plant data systems including the Emergency Response Data System (ERDS) and Safety Parameter Display System (SPDS). The loss of PPC requires alternate methods, as described in plant procedures, to be used for the above described functions. Therefore, appropriate assessment of plant conditions, notifications and communications can still be made, if required, during the time that the PPC is inoperable. This report is being made in accordance with 10 CFR 50.72(b)(3)(xiii) which is any event that results in a major loss of emergency assessment capability, offsite response capability or offsite communications capability. As previously stated, alternate means remain available to assess plant conditions, make notifications and accomplish required communications, as necessary. An additional notification will be provided when the PPC operability is restored.</br>The licensee notified the NRC Resident inspector.</br>* * * UPDATE AT 2309 ON 9/28/2009 FROM JOSHUA SISAK TO MARK ABRAMOVITZ * * *</br>At 2255 hours EDT on Sept 28, 2009, the Plant Process Computer was restored to service.
