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

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
