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

  - 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
* Requesting NRC approval to revise WF3 UFSAR 15.4.3.1 Fuel Misload Event
* Submittal in March 2018
* Requesting approval early March 2019 in support of WF3 restart following Refuel 22
