ts to members of the public in unrestricted areas, is conducted using the guidance in SRP Section 2.3.5, “Long-Term Atmospheric Dispersion Estimates for Routine Releases.” The review addresses the design of the plant stack and building ventilation exhaust vents, as they relate to their site locations, release heights, exhaust flow and velocity rates, and flow temperatures in assigning types of releases (e.g., as ground, mixed mode, or elevated releases). 10. The review of the basis of expected radiological source terms, as they relate to process and effluent streams monitored by the PERMISS, is conducted using the guidance in SRP Sections 11.2, 11.3, and 11.4, with the basis of the source terms provided in SRP Section 11.1, “Source Terms.” 11. The review of the acceptability of the design analyses, procedures, and criteria used to establish the ability of seismic Category I structures housing the system and supporting systems to withstand the effects of natural phenomena, such as the safe-shutdown earthquake, the probable maximum flood, and tornadoes and tornado missiles, is performed using the guidance in SRP Section 3.3.1, “Wind Loadings”; SRP Section 3.3.2, “Tornado Loadings”; SRP Section 3.4.2, “Analysis procedures”; SRP Section 3.5.3, “Barrier Design Procedures”; SRP Section 3.7.1, “Seismic System Analysis” through 11.5-10 Draft Revision 6 – August 2014 SRP Section 3.7.4, “Seismic Instrumentation”; SRP Section 3.8.4, “Other Seismic Category I Structures”; and SRP Section 3.8.5, “Foundations.” 12. The review of the acceptability of the seismic and quality group and safety classifications for structures and system components is performed under SRP Section 3.2.1, “Seismic Classification,” and SRP Section 3.2.2, “System Quality 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
