Content:
ed operational occurrences, are kept as low as practicable. Appendix I provides numerical guidance for this requirement. Meeting the requirements of these regulations provides assurance that radiation doses from normal operation and from anticipated operational occurrences will not result in exposures that could cause measurable damage. Atmospheric dispersion estimates are significant inputs in assessments performed to demonstrate compliance with these requirements. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. The procedures outlined below are used to review CP applications, ESP applications, and COL applications that do not reference an ESP to determine whether data and analyses for the proposed site meet the acceptance criteria given in Subsection II of this SRP section. For reviews of OL applications, these procedures are used to verify that the data and analyses remain valid and that the facility’s design specifications are consistent with these data. As applicable, reviews of OLs and COLs include a determination on whether the content of technical specifications related to the onsite meteorological monitoring program is acceptable and whether the technical specifications reflect consideration of any identified unique conditions. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant's evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. Meteorological Instrumentation The basic meteorological parameters measured by instrumentation should include wind direction and wind speed at two levels, ambient air temperature difference between two levels, temperature, precipitation, and atmospheric moisture (at sites where water vapor is emitted, as from cooling towers or
