1. INTRODUCTION
1.1. INTRODUCTION TO FUSION FOR ENERGY
The European Joint Undertaking for ITER and the Development of Fusion Energy or 'Fusion for Energy' is a European
organisation created under the Euratom Treaty by a decision of the Council of the European Union.
'Fusion for Energy' has three main objectives:
•
Providing the European contributions to the ITER international fusion energy research project being built in
Cadarache, France;
•
Providing the European contributions to a number of joint projects with Japan that aim to accelerate the
development of fusion - the "Broader Approach";
•
Coordinating a programme of activities to prepare for the first demonstration fusion reactors that can generate
electricity (DEMO).

1.2. THE ITER DIVERTOR
One of the most technical y chal enging components of the ITER machine is the divertor, the main function of which is to
extract the power conducted in the scrape-off layer whilst maintaining the plasma purity. It includes the cassette body
(CB) and three Plasma-Facing Components (PFCs), namely the inner and outer vertical target (VT), and the dome liner
(DL).
The PFCs are actively cooled thermal shields devoted to sustain the heat and particle fluxes during normal and transient
operations as wel as during disruption and Edge Localized Modes events. The CB is aimed at supporting the PFCs,
routing the water coolant into the PFCs and providing neutron shielding.
The divertor targets and dome consist of a steel support structure on which the so-cal ed Plasma Facing Units (PFUs)
are mounted.
The PFUs consist of a plasma-facing part, the armour, which is made of either carbon fibre reinforced carbon composite
(CFC) or tungsten (W). The armour has the so-cal ed monoblock geometry which consists of a number of blocks with a
dril ed hole. Into this hole is inserted a precipitation hardened copper al oy (CuCrZr) cooling tube, the heat sink, which is
intimately joined to the blocks.
The armour material of the upper region of the VTs and the DL is W because of its low sputter yield, low tritium retention,
high melting temperature and good thermal conductivity.
During normal operation a heat flux of 5-10 MW/m2 is deposited onto the bottom segment of the VT. However the
capability to remove up to 20 MW/m2 during the transient events (“slow transient” phase) of 10 seconds has also to be
provided.
CFC is the reference design solution for the lower part of the VTs due to its absence of melting, high thermal shock and
thermal fatigue resistance (low crack propagation) and high thermal conductivity.

However, the critical issue of CFC is the high tritium retention in carbon deposited layer; that makes the CFC use during
DT operations questionable from Safety point of view. Therefore, F4E has decided to launch a R&D program aiming at
the development of a ful W divertor.
This Annex specifies the technical requirements for the supply of components to be used within the ful W divertor R&D
program and for the prequalification of EU Domestic Agency.

3.2. PROTOTYPES AND MOCK-UPS
3.2.1. DESIGN DESCRIPTION
•
W Vertical Target Qualification Prototype (W-VTQP)
The VT QP consists of three HHF units, separated by a 0.5 mm gap, mounted onto an actively cooled fabricated
supporting structure. The HHF units are made of W monoblocks (see Figure 1 and Figure 2).
- The lower part is straight and consists of 19 W blocks, separated by a 0.5 mm gap. Each of them has an axial length of
12 mm and a width of 28 mm. To reduce the joint interface stress, a pure copper interlayer is applied between the W
armour and the CuCrZr heat sink. The thickness of this interlayer is 0.5 mm.
- The upper part of the W-VTQP has a curved shape with a radius of curvature of 512 mm along the tube axis. It consists
of 14 W blocks with an axial length of 12 mm and a width of 28 mm, which shal be separated by a gap. The surfaces of
the opposite sides of the W blocks can be paral el; therefore, due to the curved shape of the component, the gap
between two adjacent blocks may not be constant but can vary between ~0.4 and ~1.2 mm at the bottom and at the top
of the blocks, respectively. The gap between W monoblocks is mandatory to decrease the thermal stress under HHF
loading. This gap can also be obtained by machining after the joining of the W monoblocks according to a procedure
mutual y agreed between the Supplier and F4E.

The cooling tube (12/15 mm ID/OD) is made of CuCrZr. A steel/CuCrZr tube-to-tube transition joint shal be foreseen
prior to welding the tube onto the steel supporting structure.
A twisted tape, with a twist ratio of 2, is inserted into the straight part of the cooling tube. It is made of pure Cu and has a
rectangular cross-section of 0.8 x12 mm2 (see Figure 3).

Figure 3 – Twisted tape and sleeve

Its aim is to increase the critical heat flux limit of the water coolant and, to a lesser extent, to increase the heat transfer
coefficient. It is fixed inside the tube via a T-shaped mechanical attachment.
This T-shaped end is engaged into a slot obtained in the CuCrZr tube. The tape is then kept in position by the 316L tube,
which is joined to the cooling tube of the W-VTQP via a sleeve (15/18 mm ID/OD), typical y made of nickel, or nickel al oy,
which is welded onto the facing ends of the CuCrZr and 316L tubes (see Figure 3).
The demonstration that the twisted tape meets the stated geometrical shape and tolerances represents a Hold Point.
Different solutions for tube-to-tube transition and swirl tape fixing may be proposed by the Supplier. These are subject to
the F4E’s approval before their implementation.
The insertion of the twisted tape into each PFC represents a Notification Point.
The box supporting structure is a welded fabricated component made of austenitic stainless steel 316L plates with a
thickness of 15 mm. It is straight in the lower part and curved in the upper part (see Figure 6).

The water coolant enters into the supporting structure via an inlet tube made of austenitic stainless steel 316L. It is routed
into the cooling tubes of the HHF units via a paral el flow. Then, it runs inside the units until it reaches the opposite end of
the supporting structure. From there, it flows into the outlet tube. The inlet and outlet tubes have an inner diameter of 25
mm and are connected to the cooling circuit via ASME 16.5 WN flanges (class 600 Lbs, DN 1”). A different hydraulic
connection, including the type of flanges, may be requested by F4E.

The HHF units are mounted onto the front steel plate via a number of 316L pieces fixed onto the supporting structure by
welding (see Figure 6).

The head of the pieces has a pad with an elongated hole. The high heat flux unit has a rear slot which is engaged onto
this pad and mechanical y attached via a nickel-aluminium-bronze (grade C63200) pin (see Figure 4).


Figure 4 – Pin attachment for the high-heat flux units
This pin, which has a diameter of 4 mm and a length of 25 mm, is inserted into the elongated hole of the piece and into
the corresponding 4 mm diameter blind hole obtained in the monoblock support. The possible sliding out of the pin is
prevented by a smal cover plug, which is spot welded onto the entrance of the blind hole of the monoblock support (see
Figure 5).

With this scheme, the pin is fixed with respect to the HHF unit but can slide inside the elongated hole of the piece head
thus enabling the thermal expansion of the unit during operation.
The monoblock support consists of a 316L block (28x20x13 mm3), which is joined onto the rear surface of the armour via
a ~1 mm thick pure copper interlayer (see Figure 7). In this way, the machining of the armour is minimised and avoids the
W having any structural function.

•
W Monoblock Mock-Ups (W-MMU )
A total of 15 W monoblocks mock-ups shal be supplied (Figure 8).

Figure 8 – W-MMU

F4E wil require the procurement of W grades from 3 possible suppliers. F4E wil decide on the material al ocation for
mock-up fabrication based on the materials characteristics and documentation that wil be made available.
The W monoblocks have a total height of 25 mm. Each mock-up has 7 W blocks, separated by a gap, with a width of 28
mm and an axial length of 12 mm.
This gap can also be obtained by machining after the joining of the W monoblocks according to a procedure mutual y
agreed between the Supplier and F4E.
The cooling tube (12/15 mm ID/OD) is made of CuCrZr. It extends by 50 mm on each side of the component to enable
the connection with the cooling circuit of the high heat flux testing facility.
To reduce the joint interface stress, a pure copper interlayer is applied between the W armour and the CuCrZr heat sink.
The thickness of this interlayer is about 0.4 -1.2 mm.

A twisted tape, with a twist ratio of 2, is inserted into the straight part of the cooling tube. It is made of pure Cu and has a
rectangular cross-section of 0.8 x12 mm2 (see Figure 9).

Figure 9 – W-MMU: Twisted tape
Its aim is to increase the critical heat flux limit of the water coolant and, to a lesser extent, to increase the heat transfer
coefficient. It is fixed inside the tube via a T-shaped mechanical attachment.
This T-shaped end is engaged into a slot obtained in the CuCrZr tube.
