ay be used as a guide(see ASTM references in the Reference section). In the performance of detailed model simulations, the review should determine if the applicant has followed a strategy such as that outlined in NUREG/CR-6805 and NUREG/CR-5621. 2.4.13-7 Revision 3 - March 2007 3. Characteristics that Affect Transport: Characteristics of both the surface and subsurface environments affect the mobility of contaminants. For instance, retardation of a subsurface contaminant is determined in part by the site-specific properties of the soil; the mixing of a contaminant in a lake can be limited by stratification. The properties used by the applicant to define the mobility and dilution of a contaminant need detailed consideration of site-specific properties unless the uncertainty in these properties is conservatively offset in the applicant’s assessment. For instance, if the applicant finds any retardation of the contaminant relative to the velocity of water to be negligible, then detailed site-specific adsorption studies may not be necessary. 4. Consideration of Other Site-Related Evaluation Criteria: 10 CFR Part 100 describes site-proximity hazards, seismic, and non-seismic evaluation criteria for power reactor applications. Subpart A to 10 CFR Part 100 addresses the requirements for applications before January 10, 1997, and Subpart B is for applications on or after January 10, 1997. The staff’s review should include evaluation of pertinent information to determine if these criteria are appropriately used in postulation of the release of radionuclides from a single tank for accidental releases of radioactive liquid effluent (see SRP Section 11.2 and BTP 11-6) in ground and surface waters at the proposed plant site. 5. 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
