2 Agenda

• Scope of Request

• PRA Model Technical Adequacy

• Seismic Approach & Precedent

• Current Schedule

• Summary & Closing Remarks

3 Scope

Submit a LAR to revise the existing 10 CFR 50.69 License Condition:

• Allows use of the alternate seismic approach, as described in the LAR, for 50.69 categorization (underlined blue text)

4 Scope

Submit a LAR to revise the existing 10 CFR 50.69 License Condition:

• Removes requirements to complete implementation items; all provisions have been met (stricken through red text)

5 PRA Technical Adequacy

• Point Beach Nuclear Plant (PBNP) internal events, including internal flooding, and fire PRA models were assessed as part of the original 10 CFR 50.69 LAR:

o 10 CFR 50.69 LAR - ML17243A201 (August 2017) o NRC Amendments 262 & 265 - ML18289A378 (November 2018)

• PRA models were also assessed as part of requesting approval for the risk-informed completion time (RICT) program:

o RICT LAR - ML22140A131 (May 2022) o Enclosure 2 of the LAR provided peer review history - M L22140A142 o NRC Amendments 271 & 273 - ML23103A133 (June 2023)

6 Alternative Seismic Approach during Categorization

• PBNP will follow the same approach as that which was approved for LaSalle (except for site-specific information).

• Brunswick LAR used as a model to revise the 50.69 license condition to add the alternate seismic approach while retaining SMA approach (ML23229A456 / ML24108A070).

• The alternate seismic approach is described in EPRI 3002017583 and in the LAR.

• LAR incorporates relevant RAIs (e.g., LaSalle RAIs, Calvert Cliffs RAIs).

7 Point Beach is a Tier 2 Site

• The GMRS exceeds the SSE in a portion of the response spectrum between 1.0 Hz and 10 Hz.

• PBNP did not develop an SPRA in response to the NRCs review of insights from the Fukushima Dai-ichi accident.

• PBNP meets Tier 2 criteria per EPRI 3002017583

88 Current Schedule

• Plan is to submit LAR on the docket in September 2024

• Approval requested within one year after acceptance

• Plan to implement the amendment within 60 days

9 Summary and Closing Remarks

• PRA models are technically adequate and have been reviewed by the NRC in previous applications.

• LAR requests approval to adopt an alternative seismic approach during 10 CFR 50.69 risk-informed categorization, in addition to the currently licensed SMA approach.

• LAR is consistent with precedent (Brunswick LAR, LaSalle process).

• PBNP is considered a Tier 2 site per EPRI 3002017583.

• LAR i mplements learnings from other submittals (e.g., St. Lucie RAIs).
