  1. Release of Materials from Accelerators Accelerator Safety Workshop E. Lessard Collider-Accelerator Department August 12-14, 2008

  2. DOE Metals Moratorium • In CY2000 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.

  3. 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.

  4. 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 10CFR835.

  5. 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 re-fabricated into new products.

  7. 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 CY2000? • Q: What about metals released from a former radiological area, reused for its intended purpose in a non-radiological area?
