REVIEW RESPONSIBILITIES Primary Structural Engineering Branch (SEB) Secondary None I. AREAS OF REVIEW The following areas relating to procedures utilized in the design of seismic Category I structures, shields, and barriers to withstand the effects of missile impact are reviewed. 1. Procedures utilized for the prediction of local damage in the impacted area. This includes estimation of the depth of penetration and, in case of concrete barriers, the potential for generation of secondary missiles by spalling or scabbing effects. 2. Procedures utilized for the prediction of the overall response of the barrier or portions thereof due to the missile impact. This includes assump- tions on acceptable ductility ratios where elasto-plastic behavior.is relied upon, and procedures for estimation of forces, moments, and shears induced in the barrier by the impact force of the missile. 3. Accident Evaluation Branch (AEB) reviews the adequacy of missiles' parameters cited in support of the applicant's conclusions concerning their suitability for the plant as part of its primary review responsibility for SRP Sec- tion 3.5.1. Structural Engineering Branch reviews the parameters reviewed by the (AEB) for consideration as an integral part of structural analysis. II. ACCEPTANCE CRITERIA SEB accepts the design of structures, shields, and barriers that must withstand the effects of environmental and natural phenomena if the relevant requirements of General Design Criteria 2 (Ref. 1) and 4 (Ref. 2) are met. The relevant requirements of General Design Criteria 2 and 4 are as follows: Rev. 1 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants. These documents are made available to the public as part of the Commission's policy to Inform the nuclear industry and the general public of regulatory procedures end
