This report constitutes a summary of the manufacturing test of the
disposal canister copper shells T54 and T55.
The copper billets were manufactured at Luvata Pori Oy, Finland. The
hot-forming and machining of the copper shells were made at Vallourec &
Mannesmann Tubes, Reisholz mill, Germany. The pipes were manufactured with the
pierce and draw method. After the manufacture and non-destructive inspections
the shells were cut in pieces and three parts of each shell were taken for
destructive testing. The parts were the bottom plate, a ring from the middle
of the cylinder and a ring from the top of the cylinder. The destructive
testing was made by Luvata Pori Oy.
The results of the examinations showed that both of the test produced copper
shells fulfilled all the specified requirements as for soundness (integrity),
mechanical properties, chemical composition, dimensions, hardness and grain
