d. Therefore, the staff finds that the RTS satisfies the requirements of GDC 23. Based on the review of the interfaces between the RTS and plant operating control systems, the staff concludes that the system satisfies the requirements of (IEEE Std 279-1971 or IEEE Std 603-1991) with regard to control and protection system interactions. Therefore the staff finds the RTS satisfies the requirements of GDC 24. Based on the review of the RTS, the staff concludes that the system satisfies the protection system requirements for malfunctions of the reactivity control system such as accidental withdrawal of control rods. Chapter 15 of the SAR and SER address the capability of the system to ensure that fuel design limits are not exceeded for such events. Therefore, the staff finds that the RTS satisfies the requirements of GDC 25. Based on the review of all the above General Design Criteria, the staff concludes that the RTS satisfies the requirements of GDC 29. The staff’s conclusions noted above are based upon the requirements of (IEEE Std 279-1971 or IEEE Std 603-1991) with respect to the design of the RTS. Therefore, the staff finds that the RTS satisfies the requirement of 10 CFR 50.55a(h). 7.2-9 Revision 6 – August 2016 The applicant or licensee has also incorporated in the system design the recommendations of task action plan items (identify item number and how implemented) that the staff has reviewed and found acceptable. In the review of the RTS, the staff examined the dependence of the RTS on the availability of essential auxiliary systems. Based on this review and coordination with those having primary review responsibility of auxiliary supporting features and other auxiliary features, the staff concludes that the design of the RTS is compatible with the functional requirements of auxiliary supporting features and auxiliary features. 2. Note: The following finding applies to systems involving computer-based components. Based on the review of software development
