1 Pre-Application Meeting License Amendment for TSTF-425 Relocation of Specific Surveillance Frequency Requirements to a Licensee Controlled Program Xcel Energy (XE)Prairie Island Nuclear Generating Plant 02-20-2018 1

2 Agenda*Background & Schedule

• Discuss-Variations from TSTF-425

-Site-specific TSSR 3.0.2

-Probabilistic Risk Assessment (PRA)

• Fire Model

• Questions and Feedback 2

3Background & Schedule

• TSTF-425-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 NEI04-10

-Planned submittal first quarter 2018

-Requesting approval by April 2019

-Implement prior to Fall 2019 Refueling Outage (RFO) 3 4Variations

• Variations for the application include

-Revised (clean) TSpages not included

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

-Cross-reference list for TSTF-425 (NUREG-1431) markups to PINGPsite specific TSSRs provided

-Administrative changes

• An expired one-time frequency extension is deleted

• Two minor formatting changes 4

5PINGP'sTSSR 3.0.2

• PINGPSR 3.0.2 contains a restriction not in NUREG-1431:

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

-PINGPSR 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 to50TSSR

• One exception -TSSR 3.8.1.8 amended in 2010 to allow the application of the 25% extension to its 24 month surveillance

requirement 5

6PINGP'sTSSR 3.0.2

• PINGPTSSR 3.0.2 does not affect application of TSTF-425 nor does it affect implementation of the

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

• SFCPAdministrative Controls maintained (TS5.5.17)

• Current Licensing Basis (CLB) maintained (TSSR 3.0.2)

-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

7PRA Technical Adequacy

• Internal Events including internal flooding

-RG1.200 peer reviewed with Appendix X to NEI05-04 finding closure review complete

• Seismic-IPEEESeismic Margins Analysis (SMA)

• Other External Hazards

-PINGPIPEEEconcluded other exter nal hazards to be negligible contributors to overall plant risk

• Shutdown Events

-Shutdown risk management program consistent with NUMARC 91-06 7 8PRA Technical Adequacy

• Fire -Fire PRA developed for NFPA-805

• NFPA-805 LAR approved August 8, 2017

• 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 RG1.200 peer reviewed with an Appendix X closure review*Fire PRA Open F&Osprovided in the Technical Adequacy Section of the SFCPLAR

-During transition, the SFCPevaluations use IPEEEFIVE results supplemented by sensitivities from Fire PRA in accordance with NEI04-10-Following implementation of NFPA-805, evaluations use the Fire PRA in accordance with NEI04-10 8

9PRA Technical Adequacy

• Conclusion

-PINGPPRA models sufficiently robust and suitable for SFCP 9 10 Questions and Feedback 10?
