Big Science projects are characterized by high funding, long periods of time, coordinated groups of scientists and technicians as well as big laboratories equipped with tools and machines specifically manufactured for the project.

Walter Tosto SpA took part in important projects in this field:


Dark Side Project

The dark side project is a program of experiments based on innovative detectors, aiming to bring dark-matter detection to a new level of sensitivity. Walter Tosto has been collaborating with Princeton University and INFN (National Institute of Nuclear Phisics) in the co-engineering and manufacturing of all the mechanical components including Cryostat, Scintillator, Screen W-Tank and Service vessels.


In 1997 Walter Tosto took part in the Borexino project for the supply of a sphere and a cylinder in Pure 316 LN Stainless Steel. Borexino is an international experiment, in the Gran Sasso National Laboratory of Italy located underground and dedicated to the observation of low-energy solar neutrinos.


The company, as part of the AMW (Ansaldo Nucleare S.p.A -Mangiarotti S.p.A - Walter Tosto S.p.A) consortium is currently involved in one of the most important projects in the fusion field: ITER (International Thermonuclear Experimental Reactor). This worldwide project represents the latest innovation in the development of the fusion energy and it is supported by the European Union, Japan, Russian Federation, United States of America, China, South Korea and India. Fusion for Energy (F4E), the UE organization that manages the European contribution to ITER has signed an agreement with the AMW consortium for the supply of seven sectors of the vacuum vessel. Such component will be placed inside the ITER cryostat and will serve as chamber to host the fusion reaction. The six years validity contract has a monetary value of over 300 million euros. The vacuum vessel complexity, its dimensions, the quantity of necessary welding and the precision degree requested for the manufacturing of the component make this supply one of the most important, both in economic and technological terms, of the entire project.



JT-60-SA is a fusion experimental project designed to support the operation of ITER and to investigate how to optimize the operation of fusion power plants that are built after ITER. It is a joint international research and development project involving Japan and Europe, and it is being built in Naka, Japan using infrastructure of the existing JT-60 Upgrade experiment. SA stands for "Super Advanced", since the experiment will have superconducting coils and will study advanced modes of plasma operation. Walter Tosto SpA has been designated by ENEA (National Agency for new technologies, energy and economic sustainable development) for supplying 18 components (casings) containing the toroidal coils of the magnetic system.
