od of complying with the relevant NRC requirements identified in Subsection II. 1. For the prediction of local damage, the equations proposed by the applicant for estimation of missile penetration are reviewed in the following manner: A. For missile penetration in concrete, the reviewer verifies that the applicant has used the empirical formulas such as the modified NDRC formula or valid test results. The reviewer also verifies that the applicant has provided sufficient barrier thickness to prevent perforation and to prevent spalling or scabbing when protection from spalling or scabbing is considered necessary. B. For missile penetration in steel, the reviewer verifies that the applicant has used the SRI equations as referred to in Subsection II. 1(B) of this SRP. If other equations are selected, adequate justification with the applicability and validity of such equations are reviewed to ensure that the results are comparable to those obtained from the aforementioned SRI equations. C. For missile penetration in composite or multi-element barriers, the reviewer verifies that the applicant has used the criteria delineated in Section II Acceptance Criteria, “SRP Acceptance Criteria” subsection 1.C of this SRP. If other criteria are proposed, the justification provided is reviewed to ensure that such equations give results which are comparable to those in “SRP Acceptance Criteria” subsection 1.C. 2. For the prediction of overall damage and response of the barrier, the reviewer verifies that the applicant has used the criteria delineated in subsection II.2 of this SRP. If other criteria are selected, the applicant's justification is reviewed to ensure that the 3.5.3-8 Revision 3 - March 2007 results obtained are at least equivalent to those obtained by using method delineated in subsection II.2. 3. Refer to SRP Section 3.5.1.3, “Turbine Missiles,” for additional information regarding the protection of SSCs from the effects of turbine missiles. 4. For review
