LOSS OF COMMUNICATIONS WITH THE INTEGRATED PLANT COMPUTER
"This is a report of a loss of emergency assessment capability as required by 10CFR50.72(b)(3)(xiii).
"At 1039 CDT on June 5, 2013, Farley Unit 2 experienced a communication failure of the Integrated Plant Computer (IPC). This represents a loss of Unit 2 automated SPDS and ERDS capability. This also rendered the Technical Support Center (TSC) non-functional for Unit 2 since the TSC relies on IPC data displays for event assessment.
"The Unit 2 IPC was returned to service at 1115 CDT, restoring all affected emergency response capability. Investigation to determine the cause of the failure is ongoing.
"With the exception of the Unit 2 IPC all systems functioned as required.
"The NRC Resident Inspector has been informed."
