ditions with the effects of environmental loadings such as earthquakes and other natural phenomena. 3. The applicant has met the requirements of GDC 4 by assuring that the design of seismic Category I foundations are capable of withstanding the dynamic effects associated with missiles, pipe whipping and discharging fluids. 4. The applicant has met the requirements of GOC 5 by demonstrating that structure systems and components either are not shared between units or that if shared they have demonstrated that sharing will not impair their ability to perform their intended safety function. The Criteria used in the analysis, design, and construction of all the plant seismic Category I foundations to account for anticipated loadings and postulated conditions that may be imposed upon each foundation during its service lifetime are in conformance with 3.8.5-9 Rev. 1 - July 1981 established criteria, codes, standards, and specifications acceptable to the Regulatory staff. These include meeting the positions of Regulatory Guide 1.142 and industry standards ACI-349 and AISC, *"Specification for Design, Fabrication and Erection of Structural Steel for Building. The use of these criteria as defined by applicable codes, standards, and specifications; the loads and loading combinations; the design and analysis procedures; the structural acceptance criteria; the .materials, quality control, and special construction techniques; and the testing and in-service surveillance requirements provide reasonable assurance that, in the event of winds, tornadoes, earth- quakes, and various postulated events, seismic Category I foundations will withstand the specified design conditions without impairment of structural integrity and stability or the performance of required safety functions. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an
