aluation of site atmospheric dispersion characteristics and the establishment of dispersion parameters such that (1) radiological effluent release limits associated with normal operation from the type of facility proposed to be located at the site can be met for any individual located off site, and (2) radiological dose consequences of postulated accidents meet the prescribed dose limits at the EAB and LPZ distances set forth in 10 CFR 50.34(a)(1). The maximum annual average atmospheric dispersion factor (χ/Q value) at or beyond the site boundary and the annual average atmospheric dispersion and deposition factors (χ/Q and D/Q values) at specific locations of potential receptors of interest are a significant input to the assessment performed to demonstrate that radiological effluent release limits associated with normal operation from the type of facility proposed to be located at the site can be met for any individual located off site. Likewise, site atmospheric dispersion characteristics are a necessary input to the assessment demonstrating that the safety features that are to be engineering into the facility, including the plant design features intended to mitigate the radiological consequences of accidents, are adequate to ensure that the offsite radiological consequences of accidents meet specified radiation dose guidelines for the EAB and LPZ. 4. The GDC set forth in Appendix A to 10 CFR Part 50 establish minimum requirements for the principal design criteria for water-cooled nuclear power plants. Specifically, GDC 19 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. Atmospheric dispersion estimates are significant inputs in assessments performed to demonstrate
