Several Considerations on Construction Site of Fusion DEMO

抄録

A fusion reactor is a human dream aiming to realize a terrestrial sun. The ITER project has been running for over ten years to create D-T burning plasma. Since a fusion DEMO design started within a framework of all-Japan system newly established in Japan, the construction site of the fusion DEMO must be investigated based on the discussions which have been performed for a long time in wide engineering fields. Some of the requirements to the site selection are discussed and summarized. The discussions are mainly focused on infrastructure which will be required to the construction site and very long timespan has been imaged from the construction to the site close after the D-T burning plasma operations. The plasma parameters and the in-vessel systems like the blanket and the diverter will not be discussed and the reactor type, such as Tokamak or Helical, is not concerned severely.
