2 Site Characteristics

This chapter discusses the envelope of site-related design parameters that the economic simplified boiling-water reactor (ESBWR) standard plant is designed to accommodate, focusing on potential nearby hazards, meteorology, hydrology, geology, seismology, and geotechnical parameters. An applicant for a combined license (COL) referencing the ESBWR design control document (DCD) will establish the actual site characteristics with respect to these areas when it applies for a COL, or it will reference an early site permit (ESP) that reflects such characteristics. In either case, the COL applicant must show that the site parameters postulated for and considered in the ESBWR design bound the actual site characteristics. Should the postulated ESBWR site design parameters not encompass the actual site characteristics, the COL applicant will need to demonstrate by some other means that the proposed facility is acceptable at the proposed site. This might be done by reanalyzing or redesigning the proposed facility. The U.S. Nuclear Regulatory Commission (NRC) staff based its evaluation of the ESBWR envelope of site-related design parameters on a review of the EBSWR DCD Tier 2, Chapter 2, " Site Characteristics, " along with the applicant's responses to the staff's requests for additional information (RAIs). The applicant stated that it meets the requirements of Title 10, Section 52.47(a)(1)(iii), of the Code of Federal Regulations (10 CFR 52.47(a)(1)(iii)) by providing postulated site parameters for the ESBWR design and demonstrating that the standard design meets the required design criteria. The applicant presented in DCD Tier 2, Chapter 2, the envelope of site-related parameters that the ESBWR standard plant is designed to accommodate. DCD Tier 2, Table 2.0-2 lists the site design parameters. DCD Tier 2, Table 2.0-2, defines the limits imposed on the acceptance criteria in Section II of the various sections in NUREG-0800, " Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants " (hereafter referred to as the SRP), by (1) the envelope of site-related parameters that the ESBWR plant is designed to accommodate, and (2) the site-related assumptions, both implicit and explicit, used in the evaluation of the ESBWR design. The applicant stated that a COL applicant referencing the ESBWR DCD must demonstrate that site characteristics for a given site are in conformance with the ESBWR DCD site design parameter values. The COL applicant should follow the applicable NRC guidance for preparing the COL application depending upon whether the COL applicant references an ESP or …
