e audit has the following objectives: A. To investigate the manner in which the applicant has implemented the structural design criteria that it committed to use for the facility B. To verify that the key structural design calculations have been conducted in an acceptable way C. To identify and assess the safety significance of those areas where the plant structures were designed and analyzed using methods other than those recommended by the SRP section 3. Preliminary Arrangements The Licensing Project Manager (LPM) arranges for the audit. The reviewer prepares the audit agenda, including specific areas of interest, and forwards it to the applicant at least 30 days before the date of the audit. The LPM should notify the appropriate Inspection & Enforcement Regional Office personnel, as well as any intervening parties, about the forthcoming audit. 4. Conduct of the Audit A. Overview of the Plant Design The applicant should present an overview of each of the key structures including a brief description, assumptions, modeling techniques, and technique features of design, as well as any deviations from those committed to in the SARs. B. Audit of Design Calculations The auditing personnel review the design calculations for the structures identified during the review of the applicant's design report. The participants in the audit should discuss and resolve any questions such as those regarding the structural modeling, analysis, proportioning of the members, and computer runs. If resolution of the questions requires additional engineering data from and further analysis by the applicant, the specific follow-up action items should be identified and noted in the meeting minutes for subsequent resolution. 3.8.4-26 Draft Revision 4 – December 2012 5.
