Package Type

The 3948A SAFTAINER is designed as an Industrial Package in accordance with the IAEA Regulations for the Safe Transport of Radioactive Material. The SAFTAINER is specifically designed as a transport container, but can also be used as a disposal (at LLWR) container.


The 3948A SAFTAINER is designed and tested to ISO standards, approved in accordance with CSC requirements and is certified as an Industrial Package Type 2 (IP-2) Transport Package.


The 3948A SAFTAINER is a large volume reusable container for the transport of bulk quantities of radioactive materials.

The 3948A SAFTAINER is constructed from mild steel and has a large single door at one end, fitted with a double seal system. The door is closed by a hydraulic closure system, and secured with a mechanical locking mechanism. The hydraulic closing system is operated by an air driven pump and is also provided with a manual hand operated backup system. The container is finished inside and out with a durable paint finish for corrosion protection.

The 3948A SAFTAINER floor incorporates anchorage points to suit a range of standard handling/tie-down equipment to suit customer needs.


The 3948A SAFTAINER is a resealable containment vessel leak tested on manufacture. The door has a double seal with an interspace between the seals; the interspace facilitates leakage testing, after closure, to ensure that the seals achieve the prescribed level of leak tightness.
