ese requirements using NRC and industry guidance in developing operational programs. Meeting the guidance of SRP Section 11.5 and RG 1.143 provides reasonable assurance that the requirements of GDC 60 will be met and that releases of radioactive materials during normal operations and AOOs will not result in offsite radiation doses that exceed the limits and design objectives specified in the regulations. 6. Compliance with GDC 63 and 64 requires installation of systems to monitor radioactive waste facilities for excessive radiation levels, and evaluate radioactive effluent discharge paths and the plant’s environs for radioactivity released during normal operation, AOOs, and postulated accidents. This SRP section relates to GDC 63 and 64 because it focuses on monitoring radiation levels within the plant, as well as radioactivity levels in effluent streams and plant environs, expected during normal operations, AOOs, and postulated accidents. In addition, the requirements of GDC 64 support the implementation of requirements specified in 10 CFR 50.34(f)(2)(viii), 10 CFR 50.34(f)(2)(xiv)(E), 10 CFR 50.34(f)(2)(xvii), 10 CFR 50.34(f)(2)(xxvi), and 10 CFR 50.34(f)(2)(xxvii). RG 1.21, RG 1.33, RG 1.151, and RG 4.15 provide guidance on radiological monitoring programs for normal operation and AOOs. ANSI N42.18-2004 and ANSI/HPS N13.1-2011 provide guidance on the selection and use of continuous radiation monitoring equipment and methods in sampling airborne radioactive materials in nuclear facilities. This version of the ANSI/HPS N13.1 standard differs significantly from the 1969 version in that it is now a performance based standard, rather than one based on prescriptive rules relying on isokinetic sampling. As noted in the Foreword to ANSI/HPS N13.1-2011, the approach to achieving representative effluent sampling presented in the revised standard represents a departure from the methodology recommended by the previous version of this standard. The standard notes that by
