Manufacturing of Prototypes for ITER First Wall Panels (FWP):

ITER will be the first fusion device to maintain fusion for long periods of time. LEADING has been involved the last 9 years in the manufacturing of different mock-ups and a full-scale prototype for the ITER FWP. The FWP are the detachable, front-facing elements of the blanket that are designed to withstand the heat flux from the plasma.

These highly technological components are made of beryllium tiles bonded with a copper alloy and 316L (N) stainless steel. Europe will manufacture 215 of the first wall panels-roughly half of the total. Technical experience in bonding, treating and machining of exotic materials have been deployed to deliver a cutting-edge prototype which is an important step in order to produce a full series of first wall panels in the near future.



Project Beryllium Reflector Assembly

Manufacturing and assembly of a beryllium reflector for the ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ISIS Neutron and Muon Source, a world-leading center for research at the STFC Rutherford Appleton Laboratory near Oxford (UK).



The Be grade designated was S-200-F from Materion Corp.  The project developed and upgraded key elements of the Target Station 1 in its ISIS neutron facility, to supply a modular solid Be reflector assembly. Indicative dimensions: Height – 700 mm; Width – 700 m; Length – 780 mm.

Leading received from the raw material supplier 13 parts with a total bulk mass of 690 kg. With all the machining sequences, the beryllium mass decreased to approx. 460 kg.

Not only the manufacturing of the beryllium, but the definition of procedures and the stages for the construction sequence were fundamental steps to meet the milestones.
