ºÚÁÏÉçapp

However ºÚÁÏÉçapp is completely unique, and a large number of its constituent parts will be first-of-a-kind. Although other large tokamaks have been built around the world, not one of them resembles the tokamak that will be assembled in Saint Paul-lez-Durance, France in terms of scale and complexity.

Adding to the complexity of ºÚÁÏÉçapp is a unique procurement program that divides the fabrication of the machine's components and systems among the seven ºÚÁÏÉçapp Members (China, the 28 members of the European Union plus Switzerland, India, Japan, Korea, Russia and the United States).
 

If the ºÚÁÏÉçapp Project was "only" about building and operating the largest tokamak in the world, things would be simpler. But ºÚÁÏÉçapp is more than that. From the beginning, the project was designed with the idea that the Members, through their participation, would each advance their own scientific, technological and industrial base in fusion, and in this way prepare for the next-step machine, a demonstration fusion reactor (see "ºÚÁÏÉçapp ... and then what?" in ºÚÁÏÉçapp Mag #3).

As a result, the ºÚÁÏÉçapp Members are involved broadly in procuring components and systems (referred to as "in-kind" procurement). A few examples? The fabrication of the ºÚÁÏÉçapp vacuum vessel sectors has been divided between Europe (7 sectors) and Korea (2 sectors); the central solenoid is a collaboration between the United States and Japan; divertor manufacturing and testing is divided between Europe, Russia and Japan; India and the United States are sharing responsibility for ºÚÁÏÉçapp's cooling water systems; the blanket system will be produced by China, Europe, Korea, Russia and the United States; and finally, six ºÚÁÏÉçapp Members (all except India) are involved with the production of ºÚÁÏÉçapp magnets.

Finalized in early 2006, the distribution of in-kind fabrication tasks was based both on the interests and the technical and industrial capacities of each of the Members.

China, India, Japan, Korea, Russia and the United States have each agreed to cover 9.1% of ºÚÁÏÉçapp construction (nine-tenths of this contribution will be supplied in kind to ºÚÁÏÉçapp, and only one-tenth in cash). Europe, host to the ºÚÁÏÉçapp Project, participates at the level of 45%, including a share of ºÚÁÏÉçapp components and systems as well as nearly all the buildings of the scientific facility. For its greater investment, Europe also reaps the lion's share of economic benefits (EUR 4 billion in contracts have been awarded for ºÚÁÏÉçapp on European territory since 2007).

To manage all of these in-kind contributions, the ºÚÁÏÉçapp—which coordinates the project—has already signed nearly 100 Procurements Arrangements with the ºÚÁÏÉçapp Domestic Agencies (one Domestic Agency has been established in each ºÚÁÏÉçapp Member). These agencies, in turn, contract out to industry for the fabrication of the component according to the very specific conditions laid out in the Procurement Arrangement documents. Since the beginning of the process, more than 1,800 contracts for design or fabrication have been awarded by the ºÚÁÏÉçapp Domestic Agencies.

In factories on three continents, the components and systems of the ºÚÁÏÉçapp plant are now taking shape. Putting it all together will be like working on the largest Erector Set in the world, with at least one million components and more than 10 million individual parts.

Managing such a unique international procurement system may often be unwieldy and complex, but without it ºÚÁÏÉçapp simply would not exist.

To conceive of the largest tokamak in the world ... to garner the support of international partners around a common project ... it was absolutely essential to go beyond traditional client-supplier relationship. A whole new form of partnership had to be invented: one that preserved the interests of both the Members and the project as a whole.

That's the challenge of ºÚÁÏÉçapp, but also its appeal: a project founded on the idea of large-scale scientific collaboration for the good of all.
