Description

Package Type

Designed as a Type B(U) Package to the IAEA Regulations for the Safe Transport of Radioactive Material.

Certification

Certified as a Type B(U) package by the UK Competent Authority.

Description

The Outer Container Drum Casket (Design No 2773) is a double-shell, welded cylindrical casket manufactured in low carbon steel with a circular bolted closure at the base.  The space between the shells is filled with phenolic resin foam as a thermal insulation.

The Inner Container Flask (Design No 2774) is a robust and compact shielded flask.  The flask is of a welded stainless steel construction incorporating lead shielding.  Access to the cavity is gained by removing a bolted flange and lead filled plug.

The assembly is carried within a carbon steel pallet which is used for both lifting by fork-lift truck and for tie-down of the package.

Containment

The bolted flange of the Inner Container Flask is in the form of a separate flange with double O-ring seals.  The interspace between the O-ring seals facilitates leakage testing to ensure that the seals achieve the prescribed levels of leak tightness.  As the flange is separate from the shielded plug, the final closure and subsequent leakage testing can be carried out in a low radiation exposure area.
