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)

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
