ed isolation dampers in series separate nonessential portions and components from the essential portions. The review for seismic design is performed by SEB and the review for quality group and seismic classification is performed by MEB as indicated in subsection I of this SRP section.55 b. Essential portions of the SFPAVS, including the isolation dampers separating essential from nonessential portions, are classified seismic Category I. Component and system descriptions in the SAR that identify mechanical and performance characteristics are reviewed to verify that the above classifications have been included, and that the P&IDs indicate any points of change in design classification. c. Design provisions have been made that permit appropriate inservice inspection and functional testing of system components important to safety. Conformance with the industry standard ASTM D3803-89, "Standard Test Methods for Radiological Testing of Nuclear-Grade Gas-Phase Adsorbers," should be demonstrated. It is acceptable if the SAR information delineates a testing and 56 inspection program and if the system drawings show the necessary test recirculation loops around fans or isolation dampers that would be required by this program. 3. The reviewer verifies that the system has been designed so that system function will be maintained as required in the event of adverse environmental phenomena or loss of offsite power. The reviewer evaluates the system, using engineering judgment and failure modes and effects analyses, to determine that: a. The failure of nonessential portions of the systems or of other systems not designed to seismic Category I standards and located close to essential portions of the system, or of nonseismic Category I structures that house, support, or are close to essential portions of the SFPAVS, will not preclude operation of the essential portions of the SFPAVS. Reference to SAR sections describing site features and the general arrangement and layout drawings will
