under SRP Section. The review procedures for pressure vessel irradiation include determinations that: A. The calculations were performed by suitable radiation transport methods, that are fundamentally more correct and accurate than diffusion methods. 4.3-17 Revision 3 - March 2007 B. The geometric modeling and source distribution is detailed enough to properly estimate the relative flux spectra at various positions from the reactor core boundary to the pressure vessel wall. C. The peak vessel wall fluence for the design life of the plant is less than 10 neutrons per square centimeter (n/cm2) for neutrons of energy greater than 1 MeV. If the peak fluence is found to be greater than this value, the reviewers of SRP Sections 5.3.2 and 5.3.3 are notified. 9. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). 10. For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following
