Background===

• Callaway LFA / VQP Program for Framatome Fuel

- Lead Fuel Assemblies (LFA) - 4 Fuel Assemblies

• 3 cycles (Cycles 25, 27, 28)

• Non-Limiting Operation (Cycle 25 only)

- Vendor Qualification Program (VQP)

• Fuel Transition Licensing Submittal

- VQP Lead Fuel Assemblies - 4 Additional Fuel Assemblies

• 3 cycles (Cycles 27, 28, 29)

• Fully Licensed Operation

• GAIA Fuel Design

• Based on currently approved methods (with some changes)

• Technical Specification changes to add Framatome methods 5

Fuel Assembly Design Description (ANP-10342P-A Revision 0, GAIA Fuel Assembly Mechanical Design)

• Standard Reconstitutable Top Nozzle

• M5 Fuel Rods

• M5 GAIA Mixing Grid (6x)

• M5 Intermediate GAIA Mixer (IGM) Grids (3x)

• Alloy 718 HMP Top (Relaxed) and Bottom Spacer Grids

• Q12 MONOBLOC Guide Tubes (24x)

• Q12 Instrument Tube

• GRIP Bottom Nozzle 6

Operating Experience (GAIA 12 ft. Design)

• LTAs have successfully completed failure-free performance in US and European reactors.

Plant (Year) Cycle Length US Plant (2015-2019) 3x 18-month cycles Europe Plant (2012-2017) 5x 12-month cycles

• In the US, GAIA fuel assemblies in batch quantity will be in operation in 2021, as will GAIA LFAs at Callaway. GAIA LFAs with EATF features are in operation at another US Plant since 2019.

- Callaway LFAs (4) - Begin operation in Cycle 25, 3 cycles

- Callaway VQP LFAs (4) - Begin operation in Cycle 27, 3 cycles

• In Europe, GAIA fuel assemblies in batch quantity are in their first cycle of operation at two plants.

Technical Specification Changes

• Tech Spec 2.1.1 - Reactor Core Safety Limits

- Revise to add Framatome DNBR and FCM limits

• Tech Spec 3.2.1 - Heat Flux Hot Channel Factor (FQ(Z))

- Revise to reflect ARCADIA based power distribution control

• Tech Spec 3.2.3 - Axial Flux Difference (AFD) (Relaxed Axial Offset Control Methodology, RAOC)

- Revise to reflect ARCADIA based power distribution control

• Tech Spec 4.2.1- Reactor Core

- Revise to refer to Zirconium clad

• Tech Spec 5.6.5 - Core Operating Limits Report (COLR)

- Revise to add Framatome methods to list of methods used to support COLR

• Tech Spec 3.7.16 - Fuel Storage Pool Boron Concentration; Tech Spec 3.7.17 - Spent Fuel Assembly Storage; Tech Spec 4.3 - Fuel Storage
