REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of meteorology Secondary - None I. AREAS OF REVIEW Chapter 2 of the SRP discusses the site characteristics that could affect the safe design and siting of the plant. The staff reviews information presented by the applicant for a construction permit (CP), operating license (OL), design certification (DC), early site permit (ESP), or combined license (COL) concerning atmospheric dispersion and dry deposition estimates for routine releases of radiological effluents to the atmosphere. This SRP section applies to reviews performed for each of these types of applications. The review covers the following specific areas: 1. Atmospheric dispersion and deposition models used to calculate concentrations in air and amount of material deposited as a result of routine releases of radioactive material to the atmosphere. 2. Meteorological data and other assumptions used as input to the atmospheric dispersion models. 3. Derivation of diffusion parameters (e.g., σz). 4. Atmospheric dispersion factors (χ/Q values) and deposition factors (D/Q values) used for assessment of consequences of routine airborne radioactive releases. 1Additional supporting information of prior DC rules may be found in DCD Tier 2 Section 14.3. 2.3.5-2 Revision 3 - March 2007 5. Points of routine release of radioactive material to the atmosphere, the characteristics of each release mode, and the location of potential receptors for dose computations. 6. Additional Information for 10 CFR Part 52 Applications: Additional information will be presented dependent on the type of application. For a COL application, the additional information is dependent on whether the application references an ESP, a DC, both or neither. Information requirements are prescribed within the “Contents of Application” sections of the applicable Subparts to 10 CFR Part 52. Review Interfaces Other SRP sections interface with this section as follows: 1. A review
