Content:
ural phenomena like the safe shutdown earthquake (SSE), the probable maximum flood (PMF), and tornado missiles is reviewed under SRP Sections 3.3.1, 3.3.2, 3.5.3, 3.7.1 through 3.7.4, 3.8.4 and 3.8.5. 3. Review of the protection of essential systems and components from the effects of flooding that may result from the PMF, failure of non-seismically supported piping, or actuation of the fire protection system to verify that essential portions of the system are adequately protected from postulated flooding is performed under SRP Section 3.4.1. 4. Review of the protection of essential systems and components from the effects of internal and external missiles to verify that sufficient physical separation or shielding has been provided to protect the essential portions of the system from missiles is performed under to SRP Section 3.5.1.1 for internally generated missiles and Sections 3.5.1.3, 3.5.1.4 and 3.5.2 for externally generated missiles. 5. Review of the protection of essential systems and components from the effects of pipe whip and jet impingement that may result from high or moderate energy piping breaks or cracks to verify that sufficient physical separation or shielding has been provided to protect the essential portions of the system from postulated high and moderate energy pipe breaks is performed under SRP Section 3.6.1. 6. Review to determine whether piping, mechanical components, and support structures are designed in accordance with applicable codes and standards is performed under SRP Sections 3.9.1 through 3.9.3. 7. Review of the inservice testing program for pumps and valves is performed under SRP Section 3.9.6. 8. Review of the seismic qualification of Category I equipment, instrumentation and electrical equipment is performed under SRP Section 3.10. 9. Review of the environmental qualification of mechanical and electrical equipment is performed under SRP Section 3.11. 10. Review to verify whether system components meet inservice inspection
