Abstract: A system for transporting radioactive materials which may include a containment vessel, a thermal shield, and an
impact limiter. The containment vessel may include a vessel body having a storage cavity for receiving radioactive
materials, a lid coupled to an upper portion of the vessel body to enclose a top end of the storage cavity, and a lid seal
such as a gasket positioned between the lid and the upper portion of the vessel body. The thermal shield may be positioned over the lid. The first impact limiter may be positioned over the thermal shield. The thermal shield may be resistant to high temperatures and may help to protect the integrity of the lid seal when the system is subjected to high temperatures, such as during a fire condition.
