- 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.
- 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.
