from the site boundary to a distance of 50 miles 80 km (50 mi) from the plant, as well as for specific 25 receptor locations. RAB provides theThe locations of specific receptors (e.g., site boundary, residence, garden, cow) are identified. Adjustments of the X/Q and D/Q 26 output may be necessary to reflect consideration of unusual site and/or meteorological conditions. Annual average X/Q and D/Q values at the specified receptor locations and at standard distances in the 16 radial sectors from the site boundary to a distance of 50 miles 80 km (50 mi) from the plant are used provided to the RAB for the calculation of appropriate 27 28 doses. For standard design certification reviews, site-related parameters, including values of X/Q, should be identified in the site parameter envelope. The specified values should be representative of credible, bounding characteristics. The reviewer verifies that the values of X/Q in the site parameter envelope are consistent with the acceptance criteria given in subsection II of this SRP section. DRAFT Rev. 3 - April 1996 2.3.5-6 For an application referencing a certified standard design, the reviewer verifies that measured site-related meteorological parameters for the proposed site have been used to derive site-specific X/Q values and that these values are consistent with those identified in the site parameter envelope for the certified design.29 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface
