regulations require licensees to include the results of this evaluation in required decommissioning cost and financial assurance updates. The DPR also requires licensees, other than power reactors, to arrange for adequate decommissioning funds by the time of license termination to remediate significant residual radioactivity to the criteria of 10 CFR 20.1402, “Radiological Criteria for Unrestricted Use.” Harmonization with International Standards The following IAEA Safety Standards and Guides provide useful information on nuclear facility safety and their principles have been incorporated into this guide: SSG-5, “Safety of Conversion Facilities and Uranium Enrichment Facilities,” SSG-6, “Safety of Uranium Fuel Fabrication Facilities,” NS-G-4.6, “Radiation Protection and Radioactive Waste Management in the Design and Operation of Research Reactors,” NS-R-5, “Safety of Nuclear Fuel Cycle Facilities,” and WS-G-3.1, “Remediation Process For Areas Affected By Past Activities And Accidents.” The difference between this guide and the IAEA Safety Standards and Guides is that the latter are generic in nature whereas this guide provides direct linkage to NRC regulations. Scope Organization of Agreement States and NRC licenses cover many different kinds of activities that reflect widely varying potential for contamination of a facility and the environment and for the generation of radioactive waste. Therefore, although this guide applies to all types of facilities, it recognizes that there is a wide range of potential contamination sources and facility conditions and so provides a risk- DG-4014, Page 4 informed approach to implementing the DPR. The risk-informed approach to implement the DPR recognizes the need for minimizing contamination to the extent practical while at the same time not requiring definitive identification and quantification of all residual radioactivity. Existing 10 CFR 20.1401(a) specifically excludes uranium recovery facilities
