Procurement Sharing

Procurement for JT-60SA is shared by two "implementing Agencies", the National Institutes for Quantum and Radiological Science and Technology (QST) for Japan, and Fusion for Energy (F4E) for Europe. Procurement arrangements for each major item of procurement are concluded between these two bodies and the Project Team, with the involvement of the EU and JA Home Teams. In practice European procurement for JT-60SA is carried out through voluntary contributions from a number of countries within Euratom, as well as by Euratom itself directly through F4E.
