Certification of SAFESHIELD 2999A

Based on the U.S. Department of Transportation regulations in 49 CFR 173.7(d), the U.S. Department of Energy (DOE) Order 460.1B codifies the authority of certification of Type-B and fissile material transportation packaging to the Office of Environmental Management (EM), except for materials of interest to national security, naval propulsion systems, and civilian radioactive waste management. DOE Order 460.1B also stipulates that the EM certification of Type B and fissile materials transportation packaging shall be in accordance with the U.S. Nuclear Regulatory Commission safety standards in 10 CFR Part 71. The Office of Licensing (EM-24) is supported by technical review teams at Argonne National Laboratory, Lawrence Livermore National Laboratory, and Savannah River National Laboratory. SAFESHIELD 2999A is a Type-B radioactive material transportation packaging designed for use by the DOE’s Isotope Program. The contents of the packaging consist of source capsules of Co-60, Cs-137, or Ir-192; solid and liquid-metal accelerator targets; ion exchange resins; and target processing wastes. No fissile materials are included. Protection against radiation and confinement of radioactivity are, therefore, the two major requirements for the safety performance of the SAFESHIELD 2999A packaging under both normal conditions of transport and hypothetical accidents. The Safety Analysis Report for Packaging (SARP) of SAFESHIELD 2999A underwent four revisions by the applicant during the entire certification review. This paper will highlight some of the technical issues in areas such as contents, shielding, and quality assurance, and will discuss how these issues interact and affect other areas such as structural, thermal, containment, operating procedures, and acceptance tests and maintenance. Also discussed in the paper is the use of an independent third party to facilitate resolution of the technical issues and move the process forward for certification of SAFESHIELD 2999A.
