F4E’s vacuum pumping specialists have celebrated an important
milestone together with their counterparts from ITER International
Organization: the first cryopump has been successfully manufactured following
the specifications of the cryopumps to be used in the torus of the machine and
cryostat. The component has been delivered on-site and will go through a series
of tests. F4E has been responsible for
the procurement of this component, which took roughly four years to be
manufactured and reached a cost of approximately 3 M EUR.
Research Instruments, Alsyom and SDMS are some of the companies that
have contributed to this technical achievement with the support of their subcontractors.
The equipment which measures 3.4 x 1.8 m and weighs close to 8 T, has been
developed in different stages and has been progressively assembled.
After the performance testing of this cryopump is successfully
completed, eight more will be manufactured under the supervision of F4E. Six of
them will be installed in the torus of the ITER device and two in the cryostat.
When ITER is operational, the gases resulting from the fusion reaction will be
pumped with the help of the six cryopumps from the lower part of the torus to
the roughing system, where they will be processed and treated in a closed loop
as part of the fuel cycle. Europe is the only party responsible for the
production of the cryopumps. The successful completion of the first one will
help towards the finalisation of the design of the reaming eight, which are
expected to be delivered in 2022.
