Background===
- The NRC staff has issued RAIs to some licensees related to Generic Letter (GL) 2016-01, Monitoring Of Neutron-Absorbing Materials in Spent Fuel Pools.
- It was agreed that RAIs could be addressed generically to yield notable regulatory efficiencies through the use of a template that could be used by all plants responding to the generic RAIs.

RAI #1 Summary
- Licensee programs are already in place and are being expanded as noted in EPRI presentation
- Current Operating Experience and EPRI research supports the current licensing basis for plants that do not have coupons There is a wide range of material variability in coupon manufacture that is represented in the coupon data Consistent water chemistry through use of EPRI SFP water chemistry guidelines
- The new EPRI work is a more coordinated method for sharing operational experience.
- Forward-looking industry-wide Learning Aging Management Program (i-LAMP)

RAI #2 Summary
- Blisters and Pits have been shown to have an insignificant impact on SFP criticality
- Results will be shown in EPRI Report 3002013119

Conclusion
- Results to-date indicate there is no loss of function of Boral in Spent Fuel Pools (SFP)
- If future findings contradict the current findings, licensees will inform the NRC and take action through the licensees Corrective Action Program
- EPRI program, built on continuous learning, will proactively review future operating experience
