and (2) radiological dose consequences of postulated accidents meet the prescribed dose limits at the exclusion area and low- population zone distances set forth in 10 CFR 50.34(a)(1). 1 The ERDS is a direct, near-real-time electronic data link between the licensee’s onsite computer system and the NRC Operations Center that provides for the automated transmission of a limited data set of selected plant parameters in the event of a radiological emergency. DG-1164, Page 2 The “General Design Criteria [GDC] for Nuclear Power Plants” set forth in Appendix A to 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities,” establish minimum requirements for the principal design criteria for water-cooled nuclear power plants. Specifically, GDC 19, “Control Room,” of Appendix A requires that a control room be provided from which actions can be taken to operate the nuclear power unit safely under normal conditions and to maintain it in a safe condition under accident conditions. Adequate radiation protection must be provided to permit access to and occupancy of the control room for the duration of accident conditions. For plants that use alternate source terms, 10 CFR 50.67(b)(2)(iii) provides similar criteria. Atmospheric dispersion estimates are significant inputs in assessments performed to demonstrate compliance with this requirement. In 10 CFR Part 50, Paragraphs 50.47(b)(4), 50.47(b)(8), and 50.47(b)(9), as well as Section IV.E.2 of Appendix E, “Emergency Planning and Preparedness for Production and Utilization Facilities,” require each applicant for an operating license or combined license to describe its plans for coping with radiological emergencies. These plans must include provisions for equipment for determining the magnitude and continuously assessing the impact of the release of radioactive materials to the environment. These plans must also include a standard emergency classification and action level scheme for determining
