review, the staff also reviews the dose analysis performed to demonstrate technical support center (TSC) habitability. The application must contain sufficient nuclear plant design information for the staff to review in making a determination regarding the acceptability of the proposed site using the radiological consequence evaluation factors identified in 10 CFR 50.34(a)(1) and General Design Criterion (GDC) 19. 2. ESP Applications that Reference Standard Reactor Designs Certified by NRC. Standard reactor designs are certified with a postulated set of short-term atmospheric relative concentration (χ/Q) values at an EAB and LPZ in lieu of site-specific meteorological data and actual distances to the EAB and LPZ. The NRC has determined, for purposes of the ESP review, that the certified standard reactor designs meet the radiological consequence evaluation factors identified in 10 CFR 50.34(a)(1), provided that the site parameters fall within those postulated in the design certification. 3. ESP Applications that Use the Plant Parameter Envelope (PPE) Approach. A PPE is a set of plant design parameters that are expected to bound the characteristics of a reactor or reactors that may be constructed at a site, and it serves as a surrogate for actual reactor design information. The PPE values are selected by the applicant to bound a range of possible current and future reactor designs. The PPE values and associated information in the ESP application must contain sufficient information for the staff to make a determination regarding the acceptability of the proposed site using the radiological consequence evaluation factors identified in 10 CFR 50.34(a)(1). 4. ESP Applications that Neither Reference the Standard Reactor Designs Certified by NRC Nor Use the PPE Approach. Applications may be received that neither reference a certified design nor use the PPE approach. For example, an application may reference a “standard” design that is not yet certified, or a custom
