The audit will be conducted over multiple sessions, as needed, and the NRC staff will develop an audit summary report to document its observations and conclusions within 90 days of the final audit session. The audit will provide the NRC staff with a better understanding of the Ginna FHRR, which was submitted March 11, 2015 (ADAMS Accession No. ML15072A009).

Specifically, the audit will provide the NRC with a better understanding of the analyses of the flooding hazards presented in the Ginna FHRR The audit is intended to support completion of the staff's review of the FHRR and the subsequent issuance of a Staff Assessment.

The enclosed audit plan outlines the process that will allow the NRC staff to identify additional information potentially necessary for licensees to supplement their FHRRs, and resolve any potential technical concerns.
