Content:
or use in assessing the habitability of the control room during and after a postulated external release of hazardous chemicals. It also describes criteria acceptable to the staff for the protection of control room operators. An otherwise unacceptable site may be shown to be acceptable if the cognizant organization agrees to change the installation or mode of operation to reduce to an acceptable level the likelihood or severity of potential accidents involving the nuclear station. 2. Environmental Protection Considerations for Assessing Site Suitability for Commercial Nuclear Power Stations 2.1.1 Atmospheric Dispersion The atmospheric characteristics at a site are an important consideration in evaluating the dispersion of radioactive effluents from both postulated accidents and routine releases in gaseous effluents. 2.1.2 Dispersion of Airborne Radioactive Material Radiation doses associated with airborne radioactive materials from routine releases and anticipated operational occurrences must be ALARA and must comply with effluent concentration limits, DG-4034, Page 28 dose limits for members of the public, the EPA’s environmental radiation standards, and Clean Air Act requirements. 2.1.2.1 Relevant Statutes and Regulations • Clean Air Act; • 10 CFR Part 20, Appendix B, “Radiation Protection Programs;” • 10 CFR 20.1101, “Radiation protection programs” o 10 CFR 20.1101(b); • 10 CFR 20.1301, “Dose limits for individual members of the public” o 10 CFR 20.1301(e); • 10 CFR 20.1302, “Compliance with dose limits for individual members of the public;” • 10 CFR 50.34a, “Design objectives for equipment to control releases of radioactive material in effluents— nuclear power reactors;” • 10 CFR 50.36a, “Design objectives for equipment to control releases of radioactive material in effluents— nuclear power reactors;” o 10 CFR 50.36a(a); and • 40 CFR Part 190, “Environmental Radiation Protection Standards for Nuclear Power Plant
