he environment,” of Appendix A, “General Design Criteria for Nuclear Power Plants,” to Title 10, Part 50, of the Code of Federal Regulations (10 CFR Part 50), “Domestic Licensing of Production and Utilization Facilities.” 7. General Design Criterion 64, “Monitoring radioactivity releases,” of Appendix A, “General Design Criteria for Nuclear Power Plants,” to Title 10, Part 50, of the Code of Federal Regulations (10 CFR Part 50), “Domestic Licensing of Production and Utilization Facilities.” 10 CFR 20.1501 requires surveys that may be necessary and are reasonable to evaluate the magnitude and extent of potential radiological hazards. In 10 CFR Part 20, “Standards for Protection against Radiation,” “survey” is defined as an evaluation of the radiological conditions and potential hazards related to radioactive material or other sources of radiation, including (1) a physical survey of the location of radioactive material and (2) measurements or calculations of levels of radiation or concentrations or quantities of radioactive material present. The design objectives set out in 10 CFR Part 50, Appendix I, provide numerical guidance on limiting conditions for operation for light- water cooled nuclear power reactors to meet the requirement that radioactive materials in effluents discharged to unrestricted areas be kept as low as is reasonably achievable (ALARA). 10 CFR 50.36a requires establishing technical specifications with procedures and controls over effluents, including reporting (1) the quantity of each of the principal radionuclides discharged to unrestricted areas in liquid and gaseous effluents and (2) other information used to estimate the maximum potential annual radiation doses to the public from radioactive effluents. In 10 CFR 20.1302, the NRC establishes requirements for surveys in the unrestricted and controlled areas and for radioactive materials in effluents discharged to unrestricted and controlled areas.
