DOE Metals Moratorium § In CY 2000 the Secretary of Energy issued a moratorium on the Department’s release of contaminated metals pending a decision by the Nuclear Regulatory Commission (NRC) whether to establish national standards. The moratorium applies to the unrestricted release for recycling of metals from radiological areas within DOE facilities. 2
Questions About DOE Metals Moratorium § Q: How long will the suspension remain in effect? § A: The suspension will remain in effect until improvements in DOE release criteria and information management have been developed and implemented. § Q: What does unrestricted release mean? § A: An item that meets the criteria for unrestricted release has no residual DOE-added radioactive material above background in it. 3
Questions About DOE Metals Moratorium § Q What does recycle mean? § A: Recycle means the material can be reintroduced into commerce (i. e. , metals can be melted and new products made from them). § Q: What is the scope of the suspension? § A: The suspension applies to the recycle of all metal types. The suspension applies to the release of metal from “radiological areas” as defined by 10 CFR 835. 4
Questions About DOE Metals Moratorium § Q: What material is not covered by the suspension? § A: Non-metal materials; the recycle and reuse of excess property for use within the DOE complex; scrap metal outside of posted radiological areas; property released prior to the suspension; and the release of property/equipment for reuse for their intended purpose. § Q: Can scrap metal from a radiological area be released for reuse offsite? § A: Yes, in some cases. Metal items may be surveyed and released as long as they are used in their present form (i. e. , for their intended purpose). The key factor in determining what is permissible is whether the metal will be melted and refabricated into new products. 5

Questions About DOE Metals Moratorium § Q: What are we doing with metals from areas that were posted radiological areas and then get de-posted? § Q: What are we doing with metals from areas that were posted radiological areas and were de-posted prior to CY 2000? § Q: What about metals released from a former radiological area, reused for its intended purpose in a non-radiological area? 7
