Agenda

  • Background & Schedule
  • Discuss

- Variations from TSTF-425

- Site-specific TS SR 3.0.2

- Probabilistic Risk Assessment (PRA)

  • Fire Model
  • Questions and Feedback 2

Background & Schedule

- Risk-Informed Justification for the Relocation of Specific Surveillance Frequency Requirements to a Licensee Controlled Program (Initiative 5b)

- Licensee controlled program called the Surveillance Frequency Control Program (SFCP) and is in accordance with NEI 04-10

- Planned submittal first quarter 2018

- Requesting approval by April 2019

- Implement prior to Fall 2019 Refueling Outage (RFO) 3

Variations

  • Variations for the application include:

- Revised (clean) TS pages not included

- TS Bases insert consistent with the April 14, 2010 NRC letter removing the frequency basis

- Cross-reference list for TSTF-425 (NUREG-1431) markups to PINGP site specific TS SRs provided

- Administrative changes

  • An expired one-time frequency extension is deleted
  • Two minor formatting changes 4

PINGPs TS SR 3.0.2

- NUREG-1431 SR 3.0.2 permits a 25% extension of the interval specified in the Frequency

- PINGP SR 3.0.2 also permits a 25% extension of the specified interval, except for Frequencies specified as 24 months

  • Not a variation to the TSTF
  • Applies to 50 TS SR
  • One exception - TS SR 3.8.1.8 amended in 2010 to allow the application of the 25% extension to its 24 month surveillance requirement 5

PINGPs TS SR 3.0.2

- Site specific SR 3.0.2 is applied to the SFCP as described in TSTF-425

- No affect on TSTF-425

  • Model License Amendment Request (LAR) unchanged
  • Model No Significant Hazards Consideration determination unchanged
  • NRC Model Safety Evaluation (SE) unchanged
  • Not considered a variation to the TSTF 6

PRA Technical Adequacy

- RG 1.200 peer reviewed with Appendix X to NEI 05-04 finding closure review complete

  • Seismic

- IPEEE Seismic Margins Analysis (SMA)

  • Other External Hazards

- PINGP IPEEE concluded other external hazards to be negligible contributors to overall plant risk

  • Shutdown Events

- Shutdown risk management program consistent with NUMARC 91-06 7

PRA Technical Adequacy

  • Fire

- Fire PRA developed for NFPA-805

  • Fire PRA reflects future state of the as-built/as-operated plant following NFPA-805 modifications

- Unit 1 - Fall 2020 RFO, Unit 2 - Fall 2019 RFO

  • Fire PRA is RG 1.200 peer reviewed with an Appendix X closure review
  • Fire PRA Open F&Os provided in the Technical Adequacy Section of the SFCP LAR

- During transition, the SFCP evaluations use IPEEE FIVE results supplemented by sensitivities from Fire PRA in accordance with NEI 04-10

- Following implementation of NFPA-805, evaluations use the Fire PRA in accordance with NEI 04-10 8

PRA Technical Adequacy

  • Conclusion

- PINGP PRA models sufficiently robust and suitable for SFCP 9
