cidents in accordance with 10 CFR Part 100, 100.11(a) and (2) onsite and offsite releases of hazardous materials in accordance with General Design Criterion 19. In the determination of the atmospheric dispersion estimates, the applicant has followed the guidelines of Regulatory Guides 1.5, 1.23, 1.24, 1.25, 1.77, 1.78, 1.95, and 1.145 (as appropriate). For an application referencing a certified design, the reviewer's evaluation must also support a concluding statement similar to the following: Measured meteorological parameters for the proposed site are consistent with those identified in the envelope of site-related meteorological parameters provided in standard plant design documents.32 DRAFT Rev. 2 - April 1996 2.3.4-8 The input to the safety evaluation report will also include a brief summary of the relative concentrations (X/Q) calculated by the staff, reference to dispersion models used, and a comparison between the values computed by the staff and the applicant. For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff’s evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site interface requirements, and combined license action items that are relevant to this SRP section.33 V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. This SRP section will be used by the staff when performing safety evaluations of license applications submitted by applicants pursuant to 10 CFR 50 or 10 CFR 52. Except in those 34 cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations.
