egulatory guides or the Commission's regulations and compliance with them Is not required. The standard review plan sections are keyed to the Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants. Not all sections of the Standard Format have a corresponding review plan. Published standard review plans will be revised periodically, as appropriate, to accommodate comments and to reflect new informa- tion and experience. Comments and suggestions for Improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission. Office of Nuclear Reactor Regulation. Washington. D.C. 2 B. 10 CFR Part 100, §100.11(a) (Ref. 4) as related to meteorological data used in the evaluation to determine an exclusion area and a low population zone. C. 10 CFR Part 50, Appendix I (Ref. 5) as related to meteorological data used in determining the compliance with the numerical guides for doses to meet the criterion of "as low as is reasonably achievable." Specific criteria necessary to meet Part 100 and Appendix I are as follows: 1. The onsite meteorological measurements programs should produce data which can be summarized to provide a description of the meteorological character- istics of the site and its vicinity for the purpose of making atmospheric dispersion estimates for both postulated accidental and expected routine airborne releases of effluents and for comparison with offsite sources to determine the appropriateness of climatological data used for design considerations. The criteria for an acceptable onsite meteorological measurements program are documented in the Regulatory Position, Section C, of Regulatory Guide 1.23 (Ref. 6). 2. The following additional criteria are used to judge the acceptability of meteorological data summaries for atmospheric dispersion estimates (Ref. 7). a: For.the Preliminary Safety Analysis Report (PSAR), at least one annual cycle of onsite meteorological data should be provided at docketing. * I b.
