SUPPLEMENTARY INFORMATION:

I. Introduction

The Nuclear Regulatory Commission (NRC or Commission) is issuing a new guide in the agency=s “Regulatory Guide” series. This series was developed to describe and make available to the public information such as methods that are acceptable to the NRC staff for implementing specific parts of the agency's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.

This guide endorses the methodologies described in the industry guidance document, Nuclear Energy Institute (NEI) 07-13, “Methodology for Performing Aircraft Impact Assessments for New Plant Designs,” Revision 8, issued April 2011. The public version of NEI 07-13 can be found in the NRC's Agencywide Documents Access and Management System (ADAMS), Accession No. ML091490723.
