MODIFICATION TO PROCESS COMPUTER THAT WILL IMPACT ERDS
"The Unit 3 Plant Process Computer System (Emergency Response and Data Acquisition System, ERDADS) ERDS link will be out of service to install phone cables for the unit 4 ERDS link and cyber security equipment cabling. Additionally we are performing several software upgrades on the unit 3 ERDADS system. These upgrades will require several computer backup operations and several interruptions to the unit 3 ERDS link capability.
"These activities will render the Unit 3 ERDS link out of service for several hours per day over the course of 3 to 5 days. In case of a plant emergency that would necessitate the activation of the unit 3 ERDS link, it can be placed in service within one (1) hour. The unit 3 SPDS functions are unaffected by this work.
"This is an 8-hour reportable event per 10 CFR 50.72(b)(3)(xiii) Major Loss of Assessment Capability. The operation of plant systems will not be affected due to this planned action.
"The licensee has informed the NRC Resident Inspector."
