The LLNL Packaging and Transportation Program's mission is to assist the United States Government in assuring the safety of radioactive material transportation and storage.


The scope of the mission is to provide support to the DOT, NRC, DOE & NNSA packaging certification processes.

This is accomplished by:

  • Direct support to the packaging certification processes is provided by performing independent, thorough and defensible technical reviews on safety-related documentation, which includes confirmatory analysis and evaluation, as needed.
  • Assuring that the packaging safety basis for design, testing and operation are compliant with regulatory requirements, to assure public safety, to provide uniformity of the evaluation process, to provide a quality assurance review, and to achieve efficiency in the certification process. SARP applications are reviewed against the requirements in Title 49 of the Code of Federal Regulations, Parts 173 through 178 (i.e., 49CFR173–178) and Title 10 of the Code of Federal Regulations, Part 71 (i.e., 10CFR71).
