(9) Electronic copies of Updated Final Safety Analysis Report, Technical Specifications, Technical Specifications Bases, Technical Requirements Manual, and Individual Plant Examination of External Events (IPEEE) if available.

(10) Site-specific responses and/or evaluations for NRC generic communications associated with license renewal that were issued after entering the PEO.

(11) Risk-ranking of top 250 basic events from your internal and external (if available) events site specific probabilistic safety analysis (PSA) sorted by Birnbaum Importance, Risk-Reduction Worth, Risk-Achievement Worth, and Fussell-Veseley (as applicable) (Provide in Excel format). Include basic event names/description.

(12) Provide a list of the top 10 risk important systems for the internal events model (and external, if available).

B. Information Requested for each AMP Selected for Review (As Applicable)
