s 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. ACCEPTANCE CRITERIA a. Reordered and clarified the links to applicable regulations and their subparts as a function of application type. b. Reorganized the description of the pre-operational monitoring program under subheadings of instrument siting, meteorological sensors, recording of meteorological sensor output, instrument surveillance, and data acquisition and reduction. Also clarified the information to be provided. c. Added a data recovery rate goal of 90 percent consistent with RG 1.23, Revision 1, and clarified its applicability. d. Eliminated the need to review evidence of how well the onsite meteorological data represent long-term conditions (this will be moved to SRP Section 2.3.2). 2.3.3-21 Draft Revision 4 – September 2018 e. Clarified the amount of meteorological data to be provided as a function of the type of application (to be consistent with RG 1.23). f. Clarified the SAR sections which should be updated resulting from a submittal of additional onsite meteorological data. III. REVIEW PROCEDURES a. Added that the Generic Technical Specifications typically require written procedures for the operational meteorological monitoring program. b. Expanded the basic meteorological parameters to include any parameters used by the applicant to determine atmospheric stability (turbulence) for the purposes of atmospheric dispersion and deposition modeling. c. Specified when atmospheric moisture measurements should be taken. d. Recommended a site visit to review the applicant’s onsite meteorological measurements program. e. Clarified the criteria for siting wind sensors in the vicinity of natural draft cooling towers. f. Added the use of wind deflector shields and heater devices for precipitation gauges. g. Discussed the need for sensors to withstand harsh
