The leading event worldwide for the exchange information on the design, construction and operation of fusion experiments—and on the technology for present fusion machines and future power plants—got off to a start on Monday 29 September in San Sebastián, Spain.

In front of the 800 scientists, engineers, developers, manufacturers and students taking part in the week-long event, ITER Director-General Osamu Motojima presented the "Progress and planning of ITER" in one of the first introductory sessions.

The symposium, organized by the Spanish Research Centre for Energy, Environment and Technology (CIEMAT), continues through Friday 3 October with oral and poster presentations, industrial and R&D exhibitions, and an ITER Industrial Infoday on Tuesday 30 September.
