the limits and design objectives specified in the regulations. The review conducted in this SRP section, with supporting information drawn from SRP Sections 11.2, 11.3, and 11.4, evaluates the method used to demonstrate compliance with these requirements. 6. Compliance with GDCs 63 and 64 requires installation of systems to (1) monitor radioactive waste facilities for excessive radiation levels and (2) survey radioactive effluent discharge paths and the plant environs for radioactivity released during normal operation, AOOs, and postulated accidents. GDC 63 and 64 relate directly to SRP Section 11.5 because they focus on monitoring radiation levels within the plant, as well as radioactivity levels in effluent streams and the plant environs, during normal operation, AOOs, and postulated accidents. The 11.5-15 Revision 5 - May 2010 requirements specified in 10 CFR 50.34(f)(2)(xvii) and 10 CFR 50.34(f)(2)(xxvii) are consistent with the requirements of GDC 64. RGs 1.21, 1.33, and 4.15 provide guidance on radiological monitoring programs for normal operation and AOOs, while ANSI N42.18- 2004 and ANSI/HPS N13.1-1999 provide guidance on the selection and use of continuous radiation monitoring equipment and methods in sampling airborne radioactive materials in nuclear facilities. The RGs cited above also provide guidance on the requirements of quality assurance programs. In addition to RG 4.15, the review addresses 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. Meeting the requirements of GDCs 63 and 64 provides reasonable assurance that the levels of radioactivity in effluents from nuclear power plants will not exceed specified limits and design objectives.
