In 2009 Siempelkamp tensioning Systems GmbH and its French
subsidiary Siempelkamp MSDG SARL received the order for the
modernization of eight stud tensioners (MSt) as well as one new
delivery for the nuclear power plant Gravelines. the operator for
all nuclear power plants in France is the association Électricité de
France (EDF).
the modernization package for the eight stud tensioners operating
in different French nuclear power plants includes an effective update
consisting of new controls and hydraulics, double turning
units and elongation measuring systems.
At the same time Siempelkamp signed a contract for a ten-year
service package that includes all stud tensioners that were
supplied, upgraded or are serviced by StS/MSDG. this is currently
the largest order in the history of StS and MSDG and, at the

same time, both companies will be the first in the Siempelkamp
Group in France that have received such a long-term
service order. Siempelkamp has an established name in France.
From 19 French nuclear power plants with a total of 58 reactors
75 % have been serviced by StS and MSDG during the last 20
years.
The status quo:
three stud tensioners (MSt) are already upgraded. three more
tensioners will be upgraded starting in 2012. next to the six stud
tensioners made by StS, the large order also includes the upgrading
of two tensioners of a different make. the installation of
the new stud tensioners including many new detailed solutions for
the nuclear power plant Gravelines is expected to be completed in
mid 2013.
