el oil level, temperature, and pressure as required for uninterrupted operation. 2. The reviewer verifies whether the system is designed to withstand the effects of seismic events, other design bases, natural phenomena, and internally- and externally-generated missiles. Review of internally-generated missiles considers the relative locations and orientations of components in the facility. 3. Piping and interconnections between systems are reviewed to verify whether single active failures will cause unacceptable results. Drawings are examined to ascertain whether sufficient space around the components permits inspection, cleaning, maintenance, and repair. 4. The seismic design bases and the seismic and quality group classifications are reviewed by interfacing reviewers as indicated in subsection I of this SRP section. The primary reviewer verifies whether essential EDEFSS portions including the isolation valves separating essential and nonessential portions are classified Quality Group C and seismic Category I. SAR component and system descriptions of mechanical and performance characteristics are reviewed to verify whether the seismic and quality group classifications are included and whether the piping and instrumentation drawings indicate any points of change at the system or system component interfaces. 9.5.4-8 Revision 3 - March 2007 5. The reviewer verifies whether the design minimizes turbulence of the sediment at the bottom of the fuel oil storage tank or any chance of deleterious material entering the system during recharging, by operator error, or due to natural phenomena. 6. The SAR descriptive information and drawings are reviewed to verify whether: A. Each storage tank is equipped with an outside fill and vent line located and protected to minimize any chance of damage from vehicles, tornado, tornado missiles, and floods. The fill and vent point should be located higher than the probable maximum flood level. Each tank also has a stick gauge connection
