Harris Nuclear Plant Technical Presentation Service Water Systems CP&L January 11, 1996 ENCLOSURE 2
Service Water Systems Pur ose Discuss assessments and ongoing actions for the Harris Nuclear Plant Service Water systems.
Service Water Systems Agenda
~ Assessments Conducted
~ Results and Actions
~ Summary
Service Water Systems Assessments Conducted e Conducted two assessments (Fall 1994)
~ Assessed implementation of GL 89-13 program including a knowledgeable industry consultant
~ Performed Service Water System Operational Performance Inspection (SWSQPI) utilizing utilitylindustryteam of nine individuals in accordance with NRC Tl 2515/118
Service Water Systems o Programmatic Issues
+ Program documentation
+ Test/inspection procedures
+ Program implementation
~ Technical Issues
+ Single failure reviews
+ ESW flow
Service Water Systems Programmatic Issues Issue:
~ Program Documentation Actions:
~ Created living program document to identify scope, responsibility, and controls activities
~ Defined
> esponsibilities for site staff, including program manager CPS.L
Service Water Systems Programmatic Issues Issue
~ Test/Inspection Procedures Actions
~ Revised test/inspection procedures
+ Improved inspection guidance
+ Strengthened acceptance criteria
+ Added guidance for actions ifacceptance criteria not met
~ Training
Issue Service Water Systems Programmatic Issues e Program Implementation Actions
~ Reviewed committed program scope e Completed heat exchanger inspections e Initiated pipe inspections o Reassessed chlorination commitment
Service Water Systems Technical Issues Issue
