on 2.3.3 “Onsite Meteorological Measurements Program” This SRP revision affirms the technical accuracy and adequacy of the guidance previously provided in Revision 3, March 2007 of this SRP (ADAMS Accession No. ML063600394). This revision captures lessons learned from the staff’s review of DC, ESP, and COL applications received during the previous decade. Changes were made to update the text with editorial and clarifying statements, including utilizing consistent terminology within this SRP section and planned updates within the other SRP 2.3 sections. For example, the term “atmospheric diffusion” was replaced with “atmospheric dispersion” because atmospheric dispersion is generally recognized as having two components: transport and diffusion. The term “atmospheric stability class” was also replaced with “atmospheric stability” due to the recognition that newer atmospheric dispersion models may be using direct measurements of atmospheric turbulence instead of classifying atmospheric stability into seven distinct classes as is currently discussed in RG 1.23, Revision 1 and associated atmospheric dispersion models. Previous SRP standard boiler-plate statements that are not applicable to this SRP section were also eliminated. Other changes incorporated in this revision include the following: I. AREAS OF REVIEW a. Clarified the description of the instrumentation review to include the siting of meteorological towers and special considerations for sites located in remote harsh environmental regions. b. Clarified the description of the resulting onsite meteorological database to include consideration of data recovery and the representativeness of the data for use in characterizing atmospheric dispersion conditions. c. Added the review of COL action items and requirements and restrictions for DC applications. Also added that COL applicants referencing a DC should address action items and requirements and restrictions included in the reference DC. II.
