Content:
ations 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 made a commitment to utilize empirical formulas such as the modified NDRC formula or valid test results. The reviewer also verifies that the applicant has made a commitment to provide sufficient barrier thickness to prevent perforation and to prevent spalling or scabbing when protection from spalling or scabbing is considered necessary. 3.5.3-3 Rev. 1 - July 1981 b. For missile penetration in steel, the reviewer verifies that the applicant has made a commitment to utilize the more conservative of the BRL formula or the Stanford equations. If other equations are selected, the applicability and validity of such equations are reviewed to assure that the results are comparable to those obtained from the Stanford equations. If sufficient justification for the use of alternate equations is not provided, additional information is requested from the applicant at the first stage of the review. c. For missile penetration in composite or multi-element barriers, the reviewer verifies that the applicant has made a commitment to utilize the criteria delineated in Section.II.l.c of this plan. If other criteria are proposed, the justification provided is reviewed to assure that such equations give results which are comparable to those referenced above. 2. For the prediction of overall damage and response of the barrier, the reviewer verifies that the applicant has made a commitment to utilize the criteria delineated in subsection II.2. of this SRP section. If other criteria are selected, the applicant's justification is reviewed to assure that the results obtained are at least as.conservative as those delineated in subsection II.2. If sufficient justification is not provided, additional information is requested from the applicant at the first stage of the review. IV. EVALUATION FINDINGS The
