While performing followup inspection activities associated with
URI 05000305/2006003-03, Potentially Inappropriate Safety/Nonsafety-Related Interface for Bearing Cooling and Flushing Water to the Safety-Related Services Water Pumps, the inspectors noted that there were other systems in the plant where the interface between nonsafety-related and safety-related systems were potentially inappropriate. Specifically, the inspectors noted that the condensate storage tank was a nonsafety-related system which interfaced directly with the safety-related
AFW System and questioned various design aspects related to the interface. At the end of the inspection period the licensee had not responded to the inspectors questions about the safety/nonsafety-related interface for the condensate storage tank system and the safety-related
AFW pumps. Therefore this issue was consider unresolved pending the review of the licensees investigation and resolution of the inspectors design interface questions (
