abstract = {This paper describes the main activities carried out in the
frame of EU-DA prequalification for the supply of Normal
Heat Flux (NHF) First Wall (FW) panels to ITER. A key part
of these activities is the manufacturing development, the
fabrication and the factory acceptance tests of a reduced
scale FW prototype (Semi-Prototype (SP)) of the NHF design.
The SP has a dimension of 221 mm × 665 mm, corresponding to
about 1/6 of a full-scale panel, with six full-scale
“fingers” and bearing a total of 84 beryllium tiles. It
has been manufactured by the AREVA Company in France. The
manufacturing process has made extensive use of Hot
Isostatic Pressing, which was developed over more than a
decade during the ITER Engineering Design Activity phase.
The main manufacturing steps for the Semi-Prototype are
recalled, with a summary of the lessons learned and the
implications with regard to the design and manufacturing of
the full-scale prototype and of the series fabrication of
the EU-DA share of the ITER first wall (215 NHF panels).The
fabricated SP is then tested under High Heat Flux (HHF) in
the dedicated test facility of JUDITH-II in
Forschungszentrum Jülich, Germany. The objective of the HHF
testing is the demonstration of achieving the requested
performance under thermal fatigue. The test protocol and
facility qualification are presented and the behaviour of
the fingers under the 7500 cycles at 2 MW/m2 is described in
detail.},
