2 Public Meeting July 12 th 2018 1
AGENDA *Introductions
- Purpose *Changes made since Nov 2017 audit
- Summary *Questions NextEra Personnel *Steve Catron Corporate Licensing
- Eric Schulz Point Beach Licensing
- Rich LaPlante Point Beach Engineering
- Ted Kulczycky Corporate PRA
PURPOSE *Provide overview of changes made to seismic and thermal hazard analysis.
- Summarize results of independent review.
Changes Made Since the Audit In Nov 2017 CAFTA based event trees and fault trees used to assess seismic and thermal hazards. Integrated Internal Events Model into seismic and thermal hazard models.
-Open findings addressed in Attachment A of PRA analysis.
Most dispositioned as no impact, conservative impact, or addressed with sensitivity analysis.
Seismic fragilities from IPEEE.
-Some IPEEE fragilities updated. Addressed modifications made to the plant post IPEEE based on IPEEE insights.
Commitment to modification that will fully protect U2 PORV control cables from missile hazards
- spring 2020.
HEPs based on latest EPRI methodology.
Quantified LERF based on bounding or conservative qualitative and quantitative assumptions related to containment integrity post construction truss failure.
Comprehensive sensitivity studies address key uncertainties. Followed guidance in RG 1.174 and NUREG 1855.
Summary of third party review Review Scope Overall methodology and results Bounding Analysis Demonstrably Conservative Analysis HRA Conformance to RG 1.174; defense in depth, safety margin, and risk acceptance guidelines.
Conformance to RG 1.200
- high level review. Reasonableness of assumptions and inputs.
Appropriate integration of structural inputs.
Appropriate integration of internal events model and Seismic IPEEE.
Uncertainty Conformance to NUREG 1855 guidance Confirm sensitivity studies address key uncertainties.
Key Comments Innovative approach supported with good arguments that justify methodology.
Confirmed key issues addressed appropriately.
Editorial comments helped clarify methodology for reviewers.
Validated assumptions were reasonable and well supported.
Recommended additional sensitivity analyses to address key uncertainties associated with quantitative and qualitative inputs and assumptions.
Supporting HRA documentation enhanced in conjunction with limited quantification revision No changes required to model structure Clarifications made on seismic/structural inputs ALL COMMENTS INCORPORATED OR RESOLVED.

Supporting evaluations based on bounding and conservative assumptions Meets RG 1.174 requirements
-PRA quality meets RG 1.200
-Open F&O impacts will be addressed Independent reviews from industry experts confirmed validity of methodology and assumptions.
