effects of missiles, pipe whipping, and discharging fluids provides a level of assurance that equipment important to safety will be capable of performing its intended safety function.27 3.5.3-5 DRAFT Rev. 2 - April 1996 III. REVIEW PROCEDURES The reviewer selects and emphasizes material from the review procedures described below as may be appropriate for a particular case. 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 made a commitment to utilize empirical formulas such as the modified NDRC formula (Ref. 3) or valid test results. The reviewer also verifies that the 28 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. 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 Ballistics Research Laboratory formula (Ref. 5) or the Stanford equations (Ref. 4). If 29 30 other equations are selected, the applicability and validity of such equations are reviewed to assure ensure that the results are comparable to those obtained from 31 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 subsection II.1.c of this plan. If other criteria are proposed, the justification provided is reviewed to assure ensure that such equations give results which are 32 comparable to those referenced above. 2. For the prediction of overall damage and response of
