- Compensatory Measures
- Resolution Strategy
- Conclusion 3INTRODUCTIONS
- NRC*NextEra Point Beach Team-Steve Catron, Fleet Licensing Manager-Anil Julka, Reliability & Risk Manager
-Eric Schultz, PB Licensing Manager

- 3 4CURRENT STATUS
- Background
- Initial Nonconformance Declaration (U1 & U2)-Turbine Driven Auxiliary Feedwater Pumps (TDAFPs) for unprotected steam supply piping
- Extent of Condition (U1 & U2)-TDAFPs for unprotected turbine exhaust stacks-Main Steam Isolation Valves, Main Steam Safety Valves, Atmospheric Dump Valves-Emergency Diesel Generator (EDG) Fuel Oil Storage Tank T-175B*4Station implemented enforcement discretion guidance documentsEGM 15-002 and DSS-ISG-2016-01 5COMPENSATORY MEASURES
- Immediate Compensatory Measures-Per DSS-ISG-2016-01 guidance
- Comprehensive Compensatory Measures-Procedurally controlled measures-FLEX equipment sharing
- Other Discernable Changes from Original Station Design-FLEX implementation-Station modifications (design basis and beyond design basis)
- 5Compensatory measures in place; original station design improved over time and enhanced ability to mitigate a tornado missile event 6RESOLUTION STRATEGY
- The resolution strategy is to validate that Tornado Missile is not a significant hazard for the site-LAR submittal and approval will clear nonconformances
- Options Considered for LAR Development-TMRE (Point Beach was a pilot plant)-Site-specific High Winds PRA (RG 1.200, Rev. 2)
- Selected Option -Site-specific High Winds PRA (RG 1.200, Rev. 2)
- 6License Amendment Request will screen out tornado missile as a significant hazard for the site 7RESOLUTION STRATEGY
- Site-specific High Winds PRA-Industry leader-Developed in 2013Updated to reflect as-built/as-operated plant
- 7Site-specific High Winds PRA is peer-reviewed to ASME Standard and Regulatory Guide 1.200, Revision 2 8CONCLUSION
- Entered Enforcement Discretion Process per EGM 2015-002
- License Amendment Request submittal based on Site-Specific High Winds PRA-Site PRA concludes Tornado Missile is below the regulatory threshold in the Standard Review Plan and screens out as a significant hazard
- Plan to submit LAR in second half of 2018
- 8License Amendment Request will screen out tornado missile as a significant hazard for the site
