Ce séminaire est organisé par l'association des Thésard de Cadarache (ASTHEC), néanmoins il est ouvert aux salariés de l'IRFM. Les nouveaux arrivants de l'IRFM devraient être particulièrement intéressés par cette présentation générale sur ITER qui fera le point sur les avancées du chantier et les problématiques de physique qui seront abordées sur ITER.
La présentation sera en français.
The goal of ITER is to demonstrate the scientific and technical feasibility of fusion energy, building on several decades of worldwide research on the physics and technology of magnetic confinement. ITER is the world’s largest and most complex energy research project undertaken with the prospect of an inexhaustible energy respectful of the environment. To meet this challenge an international collaboration of seven partners (EU, China, India, Japan, South Korea, Russia and the United States) has been established in order to build, operate ITER and share the scientific results. The presentation will summarise the motivation, the objectives, and the status of the project. The ITER project benefitted recently from bold organizational changes. These changes, aimed at creating a focused Project Team, helped greatly to accelerate the pace of the construction. The presentation will give examples of major achievements obtained recently. Among these, an outstanding result obtained collectively is the progress in the manufacture of the superconducting cables: Nearly all of the needed cable-in-conduit has been produced complying with the technical requirements.
The presentation will also address the novel physics issues which will arise in the hot magnetically confined plasmas produced in devices such as ITER. Several of these issues are related to fully developed small scale turbulence which imply physics phenomena also prevailing in the convective layers of the sun, in gas planets or in even in our atmosphere. The study of these aspects is included in the experimental programs of existing (or about to start) experiments in the world physics community. The importance for ITER of collecting data in a number of innovative physics subjects will be stressed.
