REVIEW RESPONSIBILITIES Primary - Structural Engineering Branch (SEB) Secondary - None I. AREAS OF REVIEW The following areas relating to the design of seismic Category I structures to with- stand the effects of the flood or highest ground water specified for the plant are reviewed. 1. The design parameters of the flood or highest groundwater are reviewed from the standpoint of use in defining the input parameters for the structural design criteria appropriate to account for flood and groundwater loadings. Further, for plants where the flood level is higher than the proposed grade around the plant structures, the dynamic phenomena associated with such a flooding such as currents, wind waves, and their hydrodynamic effects, are similarly reviewed. The bases for these parameters are within the review responsibility of the Hydrologic & Geotechnical Engineering Branch (HGEB) as stated in Standard Review Plan Section 2.4.2. 2. The procedures that are utilized to transform the static and dynamic effects of the flood and highest groundwater into effective loads applied to seismic Category I structures are reviewed. II. ACCEPTANCE CRITERIA SEB accepts the design of structures that must withstand the effects of the flood or highest groundwater level if the relevant requirements of General Design Criterion 2 concerning natural phenomena are.complied with. The criteria neces- sary to meet the relevant requirements of GDC 2 are as follows: 1. The flood or highest groundwater and the associated dynamic effects, if any, used in the design shall be the most severe ones that have been historically Rev. 2 - 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.
