s), layout drawings, and component descriptions are then reviewed for the following points: a. Essential portions of the system are correctly identified and are isolable from the nonessential portions of the system. The P&IDs are reviewed to verify that they clearly indicate the physical division between each portion and indicate required classification changes. System drawings are also reviewed to see that they show the means for accomplishing isolation and the system description is reviewed to identify minimum performance requirements for the isolation valves. For the typical system, the drawings and description are reviewed to verify that adequate isolation valves separate non-essential portions and components from the essential portions. 9.1.3-11 DRAFT Rev. 2 - April 1996 b. Heat exchangers, pumps, valves and piping for the cooling portion of the system are constructed to Quality Group C and designed to seismic Category I requirements in accordance with the guidance provided in Regulatory Guides 1.26 and 1.29. As an acceptable alternative, the cooling loop may be constructed to Quality Group C and nonseismic Category I requirements provided the spent fuel pool water makeup system, and the building ventilation and filtration system are designed to seismic Category I requirements, are protected from the effects of tornadoes and meet the single failure requirements. The ventilation and filtration system must also meet the guidelines of Regulatory Guide 1.52. The review for seismic design is performed by SEBthe ECGB and 90 the review for seismic and quality group classification is performed by MEB is the EMEB, as indicated in subsection I of this SRP section. 91 c. The stated quantity of fuel to be cooled by the spent fuel cooling system is consistent with the quantity of fuel stored, as stated in Section 9.1.2 of the SAR. d. For the maximum normal heat load with normal cooling systems in operation, and assuming a single active failure, the temperature of the pool
