International product details for - 2773A - SAFESHIELD
Package Type
Designed as a B(U) Package to the IAEA Regulations for the Safe Transport of Radioactive Materials
1996 Edition TS-R-1 (ST-1, Revised).

Description
The outer container, 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 insulant.
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 Design No. 2774 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 leaktightness. 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.
