n. In some cases, the scope of the standard design requires that the DCD contain information that was supplied by a utility in the past. However, simply because design information may be traditionally "licensee-supplied" does not mean that it is "out-of-scope" of the standard design. Although the top-level interface requirements are specified in Tier 1, more detailed interface requirements may be specified in Tier 2 (generally in Chapter 1), but they should be consistent with the Tier 1 information. The evolutionary designs defined the interface between the systems of the design and the site-specific systems to be physically at the walls of the major buildings of the design, such as the turbine building, reactor building, and control building. All SSCs within those buildings were considered within the scope of the design, and the SSCs outside of those buildings were considered out of scope and site-specific. Alternative definitions of interfaces may also be acceptable, such as those based on the locations of transfers of various process flows into and out of the design scope (radioactive or contaminated flows, electrical flows, heat flows, water and air flows, etc.). 9. Site Parameters Site parameters are specified in this section of Tier 1 for establishing the bounding parameters to be used in the selection of a suitable site for a facility referencing the standard design. The design is evaluated in terms of these parameters during the reviews for design certification. Therefore, to ensure that a facility built on the site remains in conformance with the design certification, a suitable site should be demonstrated to be within the bounding parameters and characteristics, and a facility should be constructed at the site in accordance with their use in the approved design. 14.3-24 March 2007 APPENDIX C DETAILED REVIEW GUIDANCE FLUID SYSTEMS REVIEW CHECKLIST The following provides guidance and rationale of what should be included in the Tier 1 Design Descriptions
