ies that the system has been designed so that facility functions are maintained, as required, in the event of adverse natural phenomena such as tornadoes, hurricanes, and floods, and a loss of offsite power. The reviewer evaluates the facility, using engineering judgment and the results of failure modes and effects analyses, to determine the following: a. The failure of portions of the facility or of other systems not designed to seismic Category I standards and located close to essential portions of the facility, or nonseismic Category I structures that house, support, or are close to essential portions of the CSF, does not preclude essential functions. Reference to SAR Chapter 2, describing site features and the general arrangement and layout drawings, as well as to the SAR tabulation of seismic design classifications for structures and facilities, will be necessary. Statements in the SAR to the effect that the above conditions are met are acceptable. (CP) b. The essential portions of the CSF are protected from the effects of floods, cold weather conditions, hurricanes, tornadoes, and internally or externally generated missiles. 'Flood protection and missile protection criteria are discussed and evaluated in detail under the SRP sections for Chapter 3 of the SAR. The location and design of the facility and structures are reviewed to determine that the degree of protection provided is adequate. A statement to the effect that the facility is located in a seismic Category I structure that is tornado, missile, and flood protected, or that components of the facility will be located in individual structures that will withstand the effects of freezing, flooding, and missiles is acceptable. c. The CSF provides sufficient net positive suction head (NPSH) at safety-related pump suction locations considering low condensate storage tank water levels. The SAR should indicate the minimum water level of the condensate storage tank and the elevation of the pump impellers. An
