systems not designed to seismic Category I standards and located close to essentialsafety-related portions of the 52 facility, or nonseismic Category I structures that house, support, or are close to essentialsafety-related portions of the CSF, does not preclude essentialsafety- 53 related functions. Reference to SAR Chapter 2, describing site features and the 54 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 essentialsafety-related portions of the CSF are protected from the effects of 55 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 independent calculation verifying the applicant's conclusion regarding pump NPSH may be necessary. d. The condensate storage tank is equipped with instrumentation to monitor the water level in the tank and alarm when the water level reaches the low-level setpoint which indicates the minimum reserve condensate storage for safety-related system
