view 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 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 end Content of Safety Analysis Reports for Nuclear Power Plants. Not all 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. Waihington, D.C. 25 to assure that adverse environmental conditions including freezing will not preclude the safety function of the UHS. e. Sharing of cooling water sources in multiunit stations. f. Applicable design requirements such as the high- and low-water levels of the source to determine their compatibility with the service water system. 2. ASB reviews the station heat input provided in the SAR for the design of the UHS with respect to reactor system heat, sensible heat, and pump work, and station auxiliary system individual and total heat loads. 3. ASB also performs the following reviews under the SRP sections indicated: a. Review of flood protection is performed under SRP Section 3.4.1, b. Review of the protection against internally generated missiles is performed under SRP Section 3.5.1.1, c. Review of the structures, system, and components to be protected against externally generated missiles is performed under SRP Section 3.5.2, and d. Review of high- and
