Technical Specification Change Implications AmOrOR
. Cycle 26 starts late May 2022
No Framatome fuel n core
. Cycle 27 starts late October 2023 8 Framatome GAlAAssemblies (4 LFAs and 4 VQP) unrestricted placement Balance of core continues to be Westinghouse-supplied fuel assemblies Presence of Framatome fuel assemblies dictates changes to:
. TS2.1.1 -ReactorCoreSafety Limits
. IS 4.2.1
- Fuel Assemblies
. IS 5.6.5 - Core Operating Limits Report (COLR)
Westinghouse methods continue to govern COLR development
. Framatome evaluations ensure compliance with limits
. New fuel supplier contract to be established late in Cycle 26 or early in Cycle 27
Tech Spec Implications (continued)
F&Jcefl
. Cycle 28 Batch load quantities of fresh fuel from selected supplier If Westinghouse is chosen:
. Westinghouse methods continue to govern CQLR development Framatome evaluations ensure compliance with limits
. No additional IS changes are needed (current Power Distribution Specs apply)
. Follow-up LAR after completion of Cycle 29 to remove changes needed for the Framatome assemblies (present in cycles 27, 28 and 29)
If Framatome is chosen:
. Framatome methods will govern CQLR development Westinghouse evaluations ensure compliance with limits
. New Power Distribution Limits Specs (TS 3.2.1 3.2.3 ) need to be in place reflecting Framatome methods
. Follow-up LAR to remove obsolete Westinghouse specifications
Tech Spec Implications (continued)
Ameren Callaway MISSOURI Energy Center
. Ameren Missouri will provide a commitment to have only one fuel vendor in order to eliminate concern regarding mixed fresh fuel batches.
. The requested License Amendment ensures the revised TS are fully in place to allow use of Framatome fuel at the time that the contracts are established
. Therefore, this LicenseAmendment Request (LAR) will:
Revise TS 2.1.1
- Reactor Core Safety Limits; TS 4.2.1
- Fuel Assemblies; TS 5.6.5 COLR as discussed earlier to accommodate Framatome fuel (needed by 9/30/2023)
Retain the current Westinghouse TS 3.2.x Power Distribution Limits TS and COLR methods
. Required for cycle 27 regardless of vendor; and thereafter, if Westinghouse is selected Add the Framatome TS 3.2.x Power Distribution Limits TS and COLR methods
. Required for cycle 28 if Framatome is selected
LCO Applicability will be mutually exclusive to ensure only one vendors methods govern COLR development
. Both vendors may perform evaluations to ensure compliance with limits
Technical Specification (TS) Changes Ameren TS 2.1.1 Reactor Core Safety Limits
Revise to add Framatome DNBR and fuel centerline temperature limits Designate Westinghouse Methods-Based as A Designate Framatome Methods-Based as B (Retains Westinghouse-based COLR Methods)
