5 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)

6 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 - ML22140A142 o NRC Amendments 271 & 273 - ML23103A133 (June 2023)

7 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).

8 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 8

9 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

10 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 implements learnings from other submittals (e.g., St. Lucie RAIs).
