REVIEW RESPONSIBILITIES Primary—Appendix B Secondary—Appendix B I. AREAS OF REVIEW This environmental standard review plan (ESRP) directs the staff’s identification and description of the environmental pathways by which radiation and radioactive effluents can be transmitted from the pro- posed plant to living organisms. The scope of the review directed by this plan should include considera- tion of (1) the pathways by which gaseous and liquid radioactive effluents can be transported to individual receptors and (2) the location of these receptors. The scope should also include quantitative information on the production of major types of foods within 80 km (50 miles) of the plant and the expected consumption of these foods by the population projected to be living in this area 5 years from the date of the licensing action under consideration. The review should be sufficiently detailed to provide input to other reviews relating to radiation dose estimates, radiological impacts, and environmental monitoring and to permit the determination of individual and population doses and their comparison with the requirements of 10 CFR 20, “Standards for Protection Against Radiation,” and 10 CFR 50. Review Interfaces The reviewer for this ESRP should obtain input from and provide input to reviewers for the following ESRPs, as indicated: ` ESRP 2.2. Obtain the present annual milk, meat, and vegetable production. NUREG-1555 5.4.1-2 October 1999 ` ESRPs 2.3.1 and 2.3.2. Obtain the transit times and dilution factors at each appropriate receptor location and transit times to unrestricted area boundaries and diluted stream flows at these boundaries. ` ESRP 2.5.1. Obtain the population distribution data for the year of interest. ` ESRP 2.7. Obtain the atmospheric transport and diffusion calculations at each receptor location. ` ESRP 3.5. Obtain the effluent release points for liquid and airborne releases. The reviewer should also verify the sources of direct radiation of onsite
