th 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 is designed in compliance with General Design Criteria 60 and the guidance of Regulatory Guide 1.143 and 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. As required by Regulatory Guide 1.143, high liquid level conditions actuate alarms both locally and in the control room.56 f. The essentialsafety-related portions of the facility are protected from the effects 57 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 essentialsafety-related portions of the CSF, or that protection from the effects of 58 DRAFT Rev. 3 - April 1996 9.2.6-10 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 corresponding SRP sections. g. Functions of the essentialsafety-related components and subsystems of the CSF 59 (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. h. 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 mitigation, then the changeover feature (automatic) should meet all
