. 3.9.4-10 Revision 3 - March 2007 For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. 1. The applicant has met the requirement of GDC 1 and 10 CFR 50.55a, with respect to designing components important to safety to quality standards commensurate with the importance of the safety functions to be performed. The design procedures and criteria used for the control rod drive system are in conformance with the requirements of appropriate ANSI and ASME Codes. 2. The applicant has met the requirements of GDC 2, 14, and 26 with respect to designing the control rod drive system to withstand effects of earthquakes and conditions of normal operation, including anticipated operational occurrences, with adequate margins to assure the system’s reactivity control function and with extremely low probability of leakage or gross rupture of the reactor coolant pressure boundary. The specified design transients, design and service loadings, combination of loads, and resulting stresses and deformations under such loading combinations are reviewed within SRP Section 3.9.3. 3. The applicant has met the requirements of GDC 27 and 29 with respect to designing the CRDS to assure its capability of controlling reactivity and cooling the reactor core with appropriate margin in conjunction with either the emergency core
