Fuel Misload Event LAR Pre-Submittal Meeting Agenda
- Problem Statement
- WF3 Current Licensing Basis
- Submittal Request
- Justification for Change
- Conclusion 3
Fuel Misload Event Problem Statement
- Integrated Fuel Burnable Absorber (IFBA) implemented at WF3 in 2006
- Fuel Misload Analysis, given in UFSAR 15.4.3.1, was no longer bounding due to the IFBA
- This condition was entered into the WF3 Corrective Action Program
- Current operability is being maintained by cycle specific analysis and compensatory measures 4
Fuel Misload Event Current Licensing Basis
Background
- Waterford 3 UFSAR 15.4.3.1 describes the fuel misload event
- The current analysis concludes no fuel failure 5
Fuel Misload Event Submittal Request Request
- Revise UFSAR 15.4.3.1 (Fuel Misload Event) for fuel failure
- Methodology is consistent with that currently given in UFSAR 15.4.3.1 with the exception that the neutronics code ANC is used instead of ROCS
- Accounts for Departure from Nucleate Boiling propagation (all rods treated as failed if a single rod in the assembly fails)
- Prior NRC approval is required for this change 6
Fuel Misload Event Justification for Change
- Complies with NUREG-0800 (Standard Review Plan) 15.4.7
- The fuel failure is bounded by the excess load with loss of AC event
- Dose consequences are within the 10CFR50.67 limits approved in Waterford 3 License Amendment 198 7
Justification for Change Precedence
- The approach is the same as the Waterford 3 UFSAR with the exception of using ANC
- The use of ANC is within the applications approved in License Amendment 200
- The NRC recently approved a similar analysis for PVNGS (ML17319A107) 8
Fuel Misload Event Conclusion
- Submittal in March 2018
- Requesting approval early March 2019 in support of WF3 restart following Refuel 22
