erformed under SRP Sections 5.4.6, 5.4.7, 6.3, and applicable sections of Chapter 15, respectively. 3. Review of the adequacy of the design, installation, inspection, and testing of I&C, including the functional design and qualification of digital I&C equipment located in a mild environment and the post-accident monitoring (PAM) equipment identified in 10 CFR 50.49(b)(3), is performed under SRP Chapter 7. Qualification guidance of digital I&C equipment located in a mild environment is also addressed in Regulatory Guide 1.209. 4. Review of the adequacy of the design, installation, inspection, and testing of electric power systems is performed under SRP Chapter 8. 5. Review of the adequacy of the design, installation, inspection, and testing of the containment spray system is performed under SRP Section 6.5.2. 6. Review of the adequacy of the design of all ventilation systems utilized to maintain a controlled environment in areas containing safety-related equipment is performed under SRP Section 9.4.5. 7. Review of the applicant’s quality assurance (QA) program to verify that it satisfies the requirements of 10 CFR Part 50, Appendix B, Criteria III, XI, and XVII is performed under SRP Chapter 17. 8. Review of design basis radiological consequence analyses associated with design basis accidents is performed under SRP Section 15.0.3. 9. Review of the adequacy of chemical conditions for qualification to accident and post- accident environments, as well as anticipated operational occurrences is performed under SRP Section 6.5.2. 3.11-5 Revision 3 - March 2007 10. The functional design and qualification of mechanical, electrical, and I&C equipment are addressed in several sections of SRP Chapter 3. For example: A. SRP 3.9.5 includes evaluation of potential adverse flow effects on mechanical and electrical equipment (such as electromatic relief valves in BWR steam systems) from pressure fluctuations and vibration caused by acoustic resonances and hydrodynamic forces.
