Over the last decade(s) there have been many new Type A and Type B shipping packages designs and new allowed fissile contents. Both ANSI/ANS Standards and the Code of Federal Regulations require an evaluation of criticality safety for each combination of shipping package configuration and content. The purpose of this session is to provide a discussion of the unique challenges and requirements for criticality safety during both transport and storage of shipping packages.
