ves, dampers, or diversion valves. The bases for establishing instrumentation alarm or system activation setpoints should be provided, taking into consideration the following: i. For liquid effluents, in-plant effluent dilution factors and dilution factors beyond the point of discharge to the site boundary and nearest offsite dose receptors ii. For gaseous and particulate effluents from plant stacks and building vents, atmospheric dispersion (χ/Q) and deposition (D/Q) factors to the site boundary and offsite dose receptors E. Non-ESF instrumentation provisions for automatic termination or diversion of releases should conform to the design guidance contained in Appendix 11.5-A. SRP Sections 7.6 and 13.3 address the review the ESF instrumentation provisions for automatic termination or diversion of releases. F. The process used to develop, review, verify, validate, and audit digital computer software used in radiation monitoring and sampling equipment, including software used to terminate or divert process and effluent streams. This aspect addresses software developed by the applicant, purchased through a vendor, or included with the instrumentation. 11.5-9 Revision 4 - March 2007 4. Provisions should be made for monitoring instrumentation, sampling, and sample analyses for all identified gaseous effluent release paths in the event of a postulated accident. For GDC 64, as it relates to potential gaseous effluent release paths, the design of systems should meet the provisions of NUREG-0718 and NUREG-0737 (item II.F.1 and Attachments 1 and 2), 10 CFR 50.34(f)(2)(vxii) and 10 CFR 50.34(f)(2)(vxxii), Appendix 11.5-A, and Regulatory Guide 1.97 (Position C). SRP BTP 7-10 (see SRP Section 7.5) provides additional guidance on the application of Regulatory Guide 1.97. In addition, the design of the gaseous waste collection and processing system should meet the guidelines referenced in SRP Sections 9.3.2, 11.3, and 13.3, as well as the following conditions: A.
