plication, 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. The evaluation of the dispersion of airborne radioactive and hazardous materials to the control room is evaluated at the COL stage. Control room habitability is a design issue and is not evaluated at the ESP stage because the evaluation of control room habitability satisfies a general design criterion and general design criteria are not addressed at the ESP stage. Control room habitability is a design issue but is not evaluated at the DC stage because site information such as meteorological conditions and the locations of hazardous materials onsite and offsite is not available at the DC stage. For a design certification review, bounding χ/Q values for design basis radiological releases to the EAB, LPZ, and control room should be in the site parameter envelope specified for the standardized design. Review Interfaces Other SRP sections interface with this section as follows: 1. A review of the definitions of the EAB and LPZ that may be used as input to this SRP section is performed under SRP Section 2.1.1. 2. A review of the identification of onsite and offsite hazardous materials that could threaten control room habitability that may be used as input to this SRP section is performed under SRP Sections 2.2.1-2.2.2 and 2.2.3. 3. A review of local meteorological conditions that could affect the atmospheric dispersion estimates that are reviewed in this SRP section is performed under SRP Section 2.3.2. 4. A review of the onsite meteorological monitoring program and the resulting meteorological database that may be used in this SRP section as input to the atmospheric dispersion estimates is performed under SPR Section 2.3.3. 5. The control room χ/Q values reviewed in this SRP section are provided as input to the review
