Content:
reactivity control systems, including the CRDS and its design for protection against the effects of postulated piping and equipment failures, is reviewed under SRP Section 4.6, “Functional Design of Control Rod Drive System.” 5. The adequacy of programs for assuring the integrity of bolting and threaded fasteners is reviewed under SRP Section 3.13, “Threaded Fasteners - ASME Code Class 1, 2, and 3.” 6. The material aspects of CRDS are reviewed under SRP Section 4.5.1, “Control Rod Drive Structural Materials.” 7. The adequacy of specified seismic, environmental, and service conditions for equipment qualification and of the overall demonstration that components of the CRDS are qualified to perform their functions is reviewed under SRP Sections 3.10, “Seismic and Dynamic Qualification of Mechanical and Electrical Equipment,” and 3.11, “Environmental Qualification of Mechanical and Electrical Equipment.” 8. The structural integrity of Code Class 1, 2, and 3 components, component supports, and core support structures is reviewed under SRP Section 3.9.3, “ASME Code Class 1, 2, and 3 Components, and Component Supports,” and “Core Support Structures.” 9. Evaluation of the adequacy of (1) the dynamic analysis methods used for seismic Category I CRDS components and assemblies, and (2) the design transients and service lifetime transient cyclic loadings used in the design and fatigue analyses of CRDS components and assemblies is performed under SRP Section 3.9.1, “Special Topics for Mechanical Components.” 10. Evaluation of the seismic and dynamic qualification of the CRDS, which may have an active function during and after a faulted plant condition, against the requirements related to component functionality assurance and seismic qualification programs, is performed under SRP Section 3.10. 3.9.4-6 Revision 4 – March 2017 11. Evaluation of the adequacy of dynamic analyses under steady state and operational flow transient conditions and the
