a probability exceeding the acceptance criteria stated herein. The objective of this special review should be to ensure that the aggregate probability of an outcome that may lead to unacceptable plant damage meets the acceptance criteria of Subsection II of this SRP section. 2.2.3-6 Revision 3 - March 2007 (A hypothetical example is a situation in which (1) the probability of shock wave overpressure greater than design overpressure is about 10-7 per reactor year from accidents at a nearby industrial facility and (2) approximately equal probabilities exist of exceeding design pressure from railway accidents, highway accidents, and shipping accidents. Individually, each probability may be judged acceptably low. However, the aggregate probability may be assessed as sufficiently great that additional design features are warranted.) 10. Review Procedures Specific to 10 CFR Part 52 Application Type A. Early Site Permit Reviews Subpart A to 10 CFR Part 52 specifies the requirements and procedures applicable to the Commission’s review of an ESP application for approval of a proposed site. Information required in an ESP application includes a description of the site characteristics and design parameters of the proposed site. The scope and level of detail of review parallel that used for a CP review. In the absence of certain circumstances, such as a compliance or adequate protection issue, 10 CFR 52.39 precludes the staff from imposing new site characteristics, design parameters, or terms and conditions on the early site permit at the COL stage. Accordingly, the reviewer should ensure that all physical attributes of the site that could affect the design basis of SSCs important to safety are reflected in the site characteristics, design parameters, or terms and conditions of the early site permit. B. Standard Design Certification Reviews DC applications do not contain general descriptions of site characteristics because this information is site-specific and will be
