Annual report 2009 - Siempelkamp

Sealing of the drums
For the safe and precise handling of radioactive waste material not only adequate drums are necessary but also the corresponding
sealing lids. Radioactive waste is often packed in drums with different capacities. Not only the fi lling of the drums must be handled
absolutely safely, but also the sealing of the drums by means of lid and screws must be carried out precisely and with full automation.
We provide the equipment that will seal off the drums, no matter how complex the requirements are.
2009: For the fi rst time a complex automatic lid screwdown
device was manufactured for the nuclear industry
For the fi rst time in 2009 we manufactured a complex automatic
lid screw-down device which Gesellschaft für Nuklear-Service mbH
(GNS) ordered from us in 2008. The scope of the order included
the construction of the machine and control technology, the
manufacturing and the factory acceptance test. The device will be
used in the new building of the central decontamination and
water treatment plant in the nuclear power plant Lubmin.
Special challenges for the implementation of this device included:
fi rst, the use of two different drum types with a correspondingly
different number of lid screws and second, the complete replacement
of all lids with different lid types.
The ingenuity of our design engineers was in high demand for
this project. Next to the pneumatic drum-lid gripper and the
positioning sensors (supplier: SPS Steuerungstechnik), 20 single
electric screw drivers had to be placed in an extremely confi ned
space. Such a complex automatic lid screw-down device in compact
design is beyond compare on the market. During the factory
acceptance test, our customer was visibly satisfi ed with the technical
solution as well as our adherence to schedules and costs.
