nnual radiation dose to the public resulting from the routine release of radioactive materials in gaseous effluents to assist in demonstrating that operations will be or are being conducted within the limits of 10 CFR Part 20 and Appendix I to 10 CFR Part 50, and to ensure that effluent control equipment design objectives and proposed operating procedures meet the Commission’s requirements for keeping levels of radioactive material in effluents to unrestricted areas as low as practicable3 • a conservative assessment by both the applicant and the regulatory staff of the habitability of the control room during postulated design-basis radiological accidents and hazardous chemical releases to demonstrate that the control room can remain occupied under accident conditions in accordance with GDC 194 • a near-real-time ongoing assessment by the licensee of atmospheric transport and diffusion immediately following an accidental release of airborne radioactive materials to provide input to the evaluation of the consequences of radioactive releases to the atmosphere and to aid in the implementation of emergency response decisions in accordance with the requirements in Appendix E to 10 CFR Part 50 • an assessment by the licensee of natural phenomena being experienced or projected beyond usual levels (e.g., high winds) for the purposes of emergency classification in accordance with 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50 DG-1164, Page 5 • a realistic assessment by both the applicant and the regulatory staff of the potential dispersion of radioactive materials from, and the radiological consequences of, a spectrum of accidents to aid in evaluating the environmental risk posed by a nuclear power plant in accordance with Subpart A to 10 CFR Part 51 • a realistic assessment by both the applicant and the regulatory staff of nonradiological environmental effects, such as fogging, icing, and salt drift from cooling towers or ponds, to aid in
