icate the physical division between each portion. System drawings are also reviewed to verify that they show the means for accomplishing isolation, and the facility description is reviewed to identify minimum performance requirements for the isolation valves. B. Safety-related portions of the CSF, including the isolation valves separating seismic Category I portions from the nonseismic portions, are classified as Quality Group C and seismic Category I. C. Design provisions have been incorporated that permit appropriate inservice inspection and functional testing of system components important to safety. It will be acceptable if the SAR delineates a testing and inspection program and if 9.2.6-9 Revision 3 - March 2007 the system drawings show the necessary test recirculation loops around pumps or isolation valves that this program would require. 3. The reviewer verifies 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/or a loss of offsite power or an SBO. 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 safety-related portions of the facility—or nonseismic Category I structures that house, support, or are close to safety-related portions of the CSF—does not preclude safety-related functions. References will be necessary to SAR Chapter 2, which describes site features and the general arrangement and layout drawings, and to the SAR tabulation of seismic design classifications for structures and facilities. Statements in the SAR that the above conditions are met are acceptable. (CP) B. The safety-related portions of the CSF are protected from the effects of floods, cold weather conditions, hurricanes, tornadoes, and
