REVIEW RESPONSIBILITIES Primary—Appendix B Secondary—Appendix B I. AREAS OF REVIEW This environmental standard review plan (ESRP) directs the staff’s evaluation and input to the environmental impact statement (EIS) of the environmental risks of accidents involving radioactive material that can be postulated for the plant under review. The scope of this review is a comparison of the offsite dose consequences and resulting health effects for design basis accidents (DBAs) as calculated by the applicant and those contained in Section 15 of the safety evaluation report (SER). Review Interfaces The reviewer for this ESRP should obtain input from or provide input to the reviewers for the following ESRPs, as indicated: ` ESRP 2.7. Obtain the dispersion data for the site. ` SER Chapter 15. Obtain input from the responsible reviewer(s) of SAR Chapter 15 to ensure consistency of the review of DBAs and offsite releases. NUREG-1555 7.1-2 October 1999 Data and Information Needs The type of data and information needed will be affected by site- and station-specific factors, and the degree of detail should be modified according to the anticipated magnitude of the potential impacts. The following data or information should be obtained. ` the list of DBAs identified by the applicant as having a potential for releases to the environment and the applicant’s analysis of the dose consequences from these accidents (from the ER or from the reviewer of SAR Chapter 15 as appropriate) ` the list of DBAs considered in the staff’s safety evaluation and the analysis of the magnitude of the source-term for offsite releases (from Chapter 15 of the safety evaluation or from the reviewer for SAR Chapter 15) ` the 50th percentile normalized concentrations (χ/Q) at appropriate distances from the effluent release points (from ESRP 2.7). II. ACCEPTANCE CRITERIA Acceptance criteria for the review of environmental impacts of postulated accidents involving radioactive material and related to the
