2、onal Standards Institute, Inc. December 3, 2012 AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by the American National Standards Institute (ANSI) to determine whether the requirements for due process, consensus, and other criteria for approval have been met by

3、the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. “Substantial agreement” means much more than a simple majority, but not necessarily unanimity. Consensu

4、s requires that all views and objections be considered and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he or she has approved the standards or not, from manuf

5、acturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. ANSI does not develop standards and will in no circumstances give interpretation on any American National Standard. Moreover, no person shall have the right or authority to issue an interpre

29、 N14.12012.) The accredited Standards Committee on Packaging and Transportation of Radioactive and Non-Nuclear Hazardous Materials, N14, under whose jurisdiction this standard was developed, has the following scope. Standards for the packaging and transportation of fissile and radioactive materials,

30、 non-nuclear hazardous materials, including waste and mixed materials, but not including movement or handling during processing and manufacturing operations. This standard supersedes American National Standard for Nuclear Materials Uranium Hexafluoride Packaging for Transport, ANSI N14.12001, Addend

31、um 1-2002, Addendum 2-2004, and Addendum 3-2005. Packaging of uranium hexafluoride (UF6) for transport is an essential part of a safe and economical nuclear industry. This standard presents information on UF6 cylinders, valves, outer protection, and shipping. The packaging and transport of UF6is sub

32、ject to regulation by government agencies having jurisdiction over packaging and transport. This standard does not take precedence over applicable U.S. Nuclear Regulatory Commission, U.S. Department of Energy, U.S. Department of Transportation, or other governmental regulations. The Committee recogn

33、izes that this standard is also used for international transportation of UF6, where international transport regulations, based on IAEA TS-R-1 (Regulations for the Safe Transport of Radioactive Material), apply. TS-R-1 uses ISO 7195 as reference for packaging of UF6for transport. ISO 7195 has been de

34、veloped from and is based on previous issues of this standard and covers the same standard cylinders. The Committee has participated and will continue to participate in the development and maintenance of ISO 7195. This standard includes references to regulatory material. For more detailed informatio

35、n, the user of this standard is encouraged to use the appropriate regulatory document. Suggestions for improvement of this standard are welcome. They should be sent to the Institute of Nuclear Materials Management, 60 Revere Drive, Suite 500, Northbrook, IL 60062. ANSI N14.1-2012 xiv This standard w

42、NAL STANDARD ANSI N14.1-2012 American National Standard for Nuclear Materials Uranium Hexafluoride Packaging for Transport 1. Scope and Purpose 1.1 Scope This standard provides criteria for packaging used for transport of uranium hexafluoride (UF6). It includes specific information on design and fab

43、rication requirements for the procurement of new UF6packaging for transportation of 0.2205 lb (0.1 kg) or more of UF6. This standard also defines the requirements for in-service inspections, cleanliness, and maintenance for packaging in service. Packaging currently in service and not specifically de

44、fined in this standard are acceptable for use, provided that they are used within their original design limitations and are inspected, tested, and maintained so as to comply with the intent of this standard. Also included are cylinder loadings, shipping requirements, and requirements for valves, plu

45、gs, and valve protectors. Imperial units shown in this standard may be converted to metric units and rounded when not in conflict with the functional specification. 1.2 Purpose This standard is intended to provide for compatibility of UF6packaging among different users within the nuclear industry. I

46、t will assist in providing guidance and criteria for shipment of UF6. 2. Normative References The following standards and references contain provisions, which, through reference in this text, constitute provisions of this American National Standard.
