de that permit appropriate inservice inspection and functional testing of system components important to safety. Compliance with the industry standard American Society for testing and Materials (ASTM) D3803-89, “Standard Test Methods for Radiological Testing of Nuclear-Grade Gas-Phase Adsorbers,” should be demonstrated. The design is acceptable if the SAR information delineates a testing and 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 and the SAR tabulation of seismic design classifications for structures and systems will be necessary. Statements in the SAR that verify that the above conditions are met are acceptable. B. The essential portions of the SFPAVS are protected from the effects of floods, hurricanes, tornadoes, and internally and externally generated missiles. Flood and missile protection criteria are discussed and evaluated in detail in SRP Chapter 3. The location and the design of the system, structures, and fan rooms (cubicles) are reviewed to determine that the degree of protection is adequate. A statement to the effect that the system is located in a tornado-, missile-, and
