hout scram (ATWS), along with the examination of boron mixing issues associated with the advanced BWR (ABWR), ESBWR and its ATWS response, performed under SRP Section 15.8. 22. The review of technical specifications is performed under SRP Section 16.0. 23. The review of quality assurance is performed under SRP Chapter 17. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. 9.3.5-4 Revision 3 - March 2007 II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. GDC 2, as it relates to the ability of structures housing the system and the system itself to withstand the effects of earthquakes. 2. GDC 4, as it relates to the dynamic effects associated with flow instabilities and loads, such as water hammer. 3. GDC 5, as it relates to structures, systems, and components important to safety not being shared among nuclear power units unless it can be demonstrated that sharing will not impair their ability to perform their safety function. 4. GDC 26, as it relates to the requirement that two independent reactivity control systems of different design principles be provided and the requirement that one of the systems be capable of holding the reactor subcritical in the cold condition. 5. GDC 27, as it relates to the requirement that the reactivity control systems have a combined capability, in conjunction with poison addition by the ECCS, to reliably control reactivity changes under postulated accident conditions. 6. 10 CFR 50.62(c)(4), as it relates to the SLCS being capable of reliably injecting a borated water solution into the reactor pressure vessel (RPV) at a boron concentration, boron enrichment, and flow rate that provides sufficient reactivity control and the need for the system to have automatic initiation, where required under the rule, to satisfy ATWS risk reduction requirements. 7. 10 CFR 52.47(b)(1), which requires that a DC
