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. 9.2.6-5 Rev. 2 - July 1981 d. The condensate storage tang 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 supply. e. The condensate storage tank overflow piping is connected to the radwaste system. The outdoor storage tank has a dike or retention basin capable of preventing runoff in the event of a tank overflow or tank failure; for a nonsafety-related storage facility, the need for a seismic Category I dike or retention basin is reviewed. f. The essential portions of the facility are protected from the effects of high- and moderate-energy line breaks or cracks. Layout drawings are reviewed to assure that no high- or moderate-energy piping systems are close to essential portions of the CSF, or that protection from the effects of failure will be provided. The means of providing such protection will be given in Section 3.6 of the SAR, and the procedures for reviewing this information are given in the corres- ponding SRP sections. g. Functions of the essential components and subsystems of the CSF (i.e., those necessary for 'plant safe shutdown) will not be precluded by a loss of offsite power. The CSF design will be acceptable in this regard if minimum system requirements are met with onsite power. b. The condensate storage tank has design provisions that automatically transfer, as required, from a normal nonsafety-related source to a seismic Category I source. i. If a changeover from a nonsafety-related condensate storage source to a safety-related water source is required for safe shutdown or accident
