Supplemented Communications Assessment Attachment to GNRO-2016/00010 Page 1 of 211.Executive Summary: The purposeofthisreportisto document performanceofan NRC-requested assessment of the current communications systems and equipmentusedattheGrandGulf Nuclear Station(GGNS)site(Unit1)duringan emergencyeventas defined by NuclearEnergyInstitute(NEI)12-01,"Guideline for AssessingBeyondDesignBasis Accident Response Staffing and Communications Capabilities.
II Power suppliesfortheexisting communications equipmenttobe creditedhavebeen assessed to determine power availabilityduringa prolonged Station Blackout(SBO)event.Thebeyonddesignbasisevents assumedinthis assessment introduce conditions that could render a significantportionof existing communications capabilities inoperable.
The assessment identified enhancements for maintaining communication capabilities for responding to emergency events.These enhancements include:*Sizingofexisting Uninterruptible PowerSource(UPS) batteries in Emergency Planning (EP)facilitiestoensurethat adequate power capacity exists.*Correction of various seismic-relatedissuesrelatedto Anchorages and Spatial Interactions.
