Group Classification,” using RG 1.143 design criteria and industry codes and standards. RG 1.143 provides guidance in assigning safety classifications to RWMS with PERMISS interfaces against natural phenomena and man-induced hazards is determining compliance with GDC 2, “Design Bases for Protection against Natural Phenomena.” 13. The review of design features and instrumentation used for the protection of potable and sanitary water systems is conducted under SRP Section 9.2 using the guidance in RG 4.21. Other systems may include demineralized water makeup system, condensate storage facilities, safety-chilled water systems, component cooling water system, an essential service water system, turbine cooling water system, and the seal water supply system. 14. The review of design features and instrumentation used for the leakage detection systems, including appropriate radiation monitoring systems, is conducted under SRP Section 12.3-12.4; and SRP Section 5.2.5, “Reactor Coolant Pressure Boundary Leakage Detection”; and BTP 5-1, “Monitoring of Secondary Side Water Chemistry in PWR Steam Generators,” as they relate to detection sensitivities and types of detectors specified for radiation monitors used in complying with NEI 97-06, “Steam Generator Program Guidelines,” Revision 3, issued January 2011; underlying Electric Power Research Institute (EPRI) Guidelines, and guidance of RG 1.29 and RG 1.45, “Guidance of Monitoring and Responding to Reactor Coolant System Leakage”; and Regulatory Issue Summary (RIS) 2009-02, “Use of Containment Atmosphere Gaseous Radioactivity Monitors as Reactor Coolant System Leakage Detection Equipment at Nuclear Power Reactors,” Revision 1, issued, May 8, 2009; and Information Notice (IN) 2005-24, “Nonconservatism in Leakage Detection Sensitivity,” dated August 3, 2005. (Revision 1). 11.5-12 Revision 6 – January 2016 15. The review of design features of steam and power conversion systems and interfaces with
