The layout design of the power supplies and switch network units includes the installation of new PS and the
re-use of the existing equipment and buildings.
Procurement of 4 switching network units for JT–60SA. In the frame of the BA agreement, Europe provides
for the procurement of the central solenoid SNU of JT–60SA. The technical specifications for the call for
tenders have been reviewed and modified to include the project progress; the system simulation model has
been integrated with thermal components in order to consider the heating/cooling behaviour of the static
components.
International Fusion Materials Irradiation Facility
The activities carried out in 2010 in the frame of the International Fusion Materials Irradiation Facility
(IFMIF) project are related to the following procurement arrangements.
Participation to the experimental activity of the ELITE loop
(Oarai, Japan) (LF 01 EU). The main components to be delivered
to Japan have been designed and the order for the procurement
of the instrumentation (Nano–ohmmeter, thermo–resistances,
datalogger for thermo–resistances, and NIs items) for the
R–meter, the E–Cubicle and the data acquistion systems (DACs)
have been issued. The order for the modification of the R–Meter
instrument itself, capable of fulfilling the Japanese safety rules,
was emitted as well.
During the second half of 2010 the procedure to issue the
contract for the final design and realization of the R–Meter box,
support structure and the assembly of the electrical cabinet for
the DACs of R–Meter and CASBA sensors was completed. In
figure 3.47 two views of the final assembly of the R–Meter, of the
magnet and of the heating system into the box are reported.
Moreover, the new design of the removable backplate (BP) as well
as the design of the frame were completed and their
thermo–mechanical analysis started. As the design of the BP had
been frozen, ENEA started the procedure for the procurement of
EUROFER.

In the figure 3.48 the 3D model of the removable BP is reported.
Lithium erosion corrosion activity (LF03 EU). During the
reporting period ENEA continued the commissioning of the
lithium loop LiFus3. A new test section was also prepared as
advised by the reviewer of the preliminary design review meeting.
The charging and draining procedures were implemented and
the performance of liquid level meters, thermocouples and
pressure transmitters checked.

blackplate prototype
During the month of November 2010 tests, the necessity to improve the control of the loop was underlined.
Thus, several thermocouples were added both in the air cooler and in the gas lines and a new pressure
transmitter was installed in the gas line over the test section. New Conax lithium level gauges have been
ordered and the procurement of a new mass flow–meter has been decided.
At the end of 2010 lithium circulation tests were performed and in December the lithium circulation by using
a procedure different from the standard one was obtained. Consequently, commissioning and testing of the
loop was stopped due to different technical and safety problems arisen during the lithium circulation tests. The
outcomes of this test suggested that the loop should be updated and a number of interventions planned.
Due to the limited time at the completion of the IFMIF project, a new test matrix was proposed and accepted
by F4E and Project Team.
