Content:
Water-Cooled Nuclear Power Plants (NRC 1974), contains guidance on summarization of meteorological data for submission with reports of releases of radioactive materials in gaseous effluents. Technical Rationale NUREG-1555 6.4-4 October 1999 The technical rationale for evaluating the applicant’s meteorological monitoring program is discussed in the following paragraphs: 10 CFR 50, Appendix I, 10 CFR 51.45(c), 10 CFR 52.17(a)(1), and 10 CFR 100.10(c)(2) require staff analyses that use onsite meteorological data. The staff considered this need for onsite data and established guidance for data collection systems to ensure that onsite data are representative. This guidance is in Section C of Regulatory Guide 1.23 (NRC 1972). Staff evaluation of compliance with 10 CFR 50, Appendix I, and the independent evaluation of site meteorological characteristics under 10 CFR 100.10(c)(2), 10 CFR 100.20(c)(2), and 10 CFR 52.17(a)(1) is based on onsite meteorological data. The staff prepared a standard format for transferring meteorological data to the NRC. This format is defined in Appendix A of ESRP 2.7. Use of the standard format facilitates reliable data transfer. Staff evaluation of the environmental impacts of routine releases of radioactive effluents to the environment uses various meteorological models. The models are described in Regulatory Guide 1.111 (NRC 1977). Section C.4 of this Guide describes summarization of meteorological data for use in the models. Staff evaluation of the environmental impacts of releases of radioactive materials in gaseous effluents from nuclear power plants involves the use of onsite meteorological data. Regulatory Guide 1.21 (NRC 1974) describes acceptable formats for inclusion of meteorological data with reports of releases of radioactive materials in gaseous effluents. III. REVIEW PROCEDURES The reviewer should verify that sufficient information has been provided to adequately assess the onsite meteorological measurements program and other
