| event text = This event is being reported pursuant to 10 CFR 50.72(b)(3)(xiii) for a loss of emergency assessment capability at the Harris Nuclear Plant. Between March 24, 2015, and April 28, 2015, the meteorological data transfer process from the sensors to the emergency response facilities stalled intermittently five times. The control room staff was unaware of this condition for a maximum of 6.6 hours at any given time. When the data transfer process was stalled and the control room staff was unaware of the issue, the staff may have used inappropriate information in implementing the emergency plan. There was no impact from this condition because there were no actual emergencies during this time.
