This particular welding is performed using a gun inserted in thetubesheet hole with a rotating head. With special tools is possibleto re-build the seat when is necessary to cut the tube alreadywelded.
Internal Bore WeldingElectro Beam Welding with PRO-BEAM partnership
For the construction of the Vacuum Vessel,Walter Tosto, with the cooperation of PRO-BEAM, has developed and qualifiedprocedures for the execution of EB welding.EB welding, thanks to the law heat inputduring the activities, allows a better controlof the related deformation.

Borexino Project
Istituto Nazionale di Fisica Nucleare & PricetonUniversity – LNGS Assergi (AQ)WT has supplied Sphere, Water Tank and ServiceEquipment for the Borexino Project.The main challenging of the project was theinstallation of a large steel structure in a very limitedaccess facility.
Part Dimensions Material
Water Tank Ø 18.000 mm SS304L
Sphere Ø 13.700 mm SS304L
Waterlock Sliding Port ☐ 4.200 mm SS304L

Nuclear Fusion
26
ITER, from Latin, means “way”. It’s themain international experiment with thepurpose of demonstrate scientific andtechnical feasibility of the “fusion” as thenew source of energy .
The ITER Project
In 2010 the Italian Consortium composed byAnsaldo Nucleare, Mangiarotti Spa, WalterTosto Spa and relevant sub‐supplier partnerswon the tender to provide 7 sectors of the IterVacuum Vessel.
27
At this moment Walter Tosto has in his portfolio 4 contracts for manufacturing equipment for nuclear fusion projects:
1. ITER Vacuum Vessel
28
2-ITER Divertor Cassette prototype
3-ITER Inner Vertical Target
29
4-JT60-SA (broader approach to ITER) Casings for Toroidal Coils

MANUFACTURING OFITER VACUUM VESSEL EU SECTORS
The activity described in the presentation of the vacuum vessel are developed by AMW
consortium in the frame of the contract with F4E
The sentences reported in the presentation not
represent necessarily the opinion of ITER
31
What is the Vacuum Vessel of ITER project ?The vacuum vessel is a hermetically‐sealed steel containerinside the cryostat that houses the fusion reaction andacts as a a first safety nuclear containment barrier. In itsdoughnut‐shaped chamber, or torus, the plasma particlesspiral around continuously without touching the walls.
The ITER vacuum vessel will be twice as large andsixteen times as heavy as any previous tokamak, withan internal diameter of 6 meters. It will measure alittle over 19 meters across by 11 meters high, andweigh in excess of 5,000 tons.
