s to construct and operate nuclear power plants. These documents are made avallable to the public as part of the Commission's policy to Inform the nuclear Industry and the general public of regulatory procedures and policies. Standard review plans are not substitutes for regulatory guides or the Commission's regulations and compliance with them Is not required. The standard review plan sections are keyed to the Standard Format and Content of Safety Analysis Report. for Nuclear Power Plant. Not a.1 sections of the Standard Format have a corresponding review plan. Published standard review plans will be revised periodically, as appropriate, to accommodate comments and to reflect new Informa- tion and experience. Comments and suggestions for Improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission. Office of Nuclear Reactor Regulation, Washington. D.C. reported for the site and surrounding area, with sufficient margin for the limited accuracy, quantity, and period of time in which the historical data have been accumulated. 2. The acceptance criteria for the flood or highest ground water level, for establishing the dynamic effects of the flood where it is above the plant grade, and for the bases for determining these site-related and hydrody- namic parameters, are established by the Hydrologic'& Geotechnical Engineering Branch (HGEB) as stated in Standard Review Plan Section 2.4.2. 3. In most situations, the flood level is below the proposed plant grade and only its hydrostatic effects need be considered. Unless the hydrostatic head associated with the flood or with the highest groundwater level is relieved by utilizing a drainage and pumping system around the foundations of structures, it has to be considered as a structural load on the base- ment walls and foundation slab of the building. Another consideration in such a situation is to prevent any uplift or floating of the structure. The total buoyancy force may be based on the flood
