to meet these objectives, ensure package integrity, and minimize the distribution of contamination to the environment. This RG endorses the methods and procedures developed by the Accredited Standards Committee on Packaging and Transportation of Radioactive and Non-Nuclear Hazardous Materials, N14, Subcommittee of the American National Standards Institute (ANSI) in ANSI N14.5-1997, “Radioactive Materials - Leakage Tests on Packages for Shipment,” issued in 1997 and reaffirmed in 2008, as a process that the NRC staff considers acceptable for meeting the regulatory requirements. Since the last review of RG 7.4, ANSI N14.5-1997 was revised in 2014 and issued as ANSI N14.5-2014. The ANSI N14.5-2014 standard contains new information and clarifications. Holders of, or applicants for, a Type B transportation package certificate of compliance (CoC), a spent fuel storage cask CoC, or a general or site-specific Independent Spent Fuel Storage Installation (ISFSI) licensee using ANSI N14.5-1997, should be aware of the Information Notice (IN) 2016-04, “ANSI N14.5-2014 Revision and Leakage Rate Testing Considerations,” which discussed ANSI N14.5-2014. In addition, two international references in RG 7.4 have been updated. These references are: 1) International Atomic Energy Agency (IAEA) Regulation TS-R-1 (ST-1) revised in 1996, “Regulations for the Safe Transport of Radioactive Material,” dated June 2000, and 2) IAEA Safety Guide TS-G-1.1 (ST-2), “Advisory Material for the IAEA Regulations for the Safe Transport of Radioactive Material,” dated June 2002) will need to be updated to: IAEA TS-R-1, “Regulations for the Safe Transport of Radioactive Material,” dated May 2009 and IAEA SSG-26, “Advisory Material for the IAEA Regulations for the Safe Transport of Radioactive Material,” dated October 2012. 11 2. What is the impact on internal and external stakeholders of not updating the RG for the known issues, in terms of anticipated numbers of licensing and
