°ÄÃÅÁùºÏ²Ê¸ßÊÖ

"The proponents of fusion power have for years been promising us a plentiful and relatively safe form of new energy. Well here, at °ÄÃÅÁùºÏ²Ê¸ßÊÖ in France, they are starting to make good on that promise."

So begins the 30-minute documentary film on °ÄÃÅÁùºÏ²Ê¸ßÊÖ and fusion that aired this past weekend on BBC Horizons.

Presenter Adam Shaw visits °ÄÃÅÁùºÏ²Ê¸ßÊÖ in the south of France as well as labs around the world (Germany, US and Canada) to learn more about the "tantalizing possibility" of fusion and its chance at transforming the world's relationship with energy.

Three additional °ÄÃÅÁùºÏ²Ê¸ßÊÖ cryostat segments have arrived in the port of Fos-sur-Mer after a one-month voyage from India.

The 60° segments make up half of Tier 2 of the cryostat base (three other Tier 2 segments are due at a later date). The 120-tonne components have been unloaded in Fos in preparation for their delivery to the °ÄÃÅÁùºÏ²Ê¸ßÊÖ site this week (weather permitting) along the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Itinerary.

Each 96-wheel transport trailer will carry a protected load that is just over 14 metres long and six metres wide.

In a tokamak fusion reactor, the plasma causes intense heating of the divertor, similar to that encountered by a space shuttle when it re-enters the Earth's atmosphere. The belly of the shuttle must be protected by special heat tiles. In the same way, the divertor surface is made of small tungsten tiles that are tilted at a grazing angle with respect to the plasma stream. The edges of the tiles, like the nose and wings of the shuttle, are subject to very intense heat flux...

At Cadarache (south of France), the Institute for Magnetic Fusion Research (CEA/DSM/IRFM) is modifying the Tore Supra plasma facility to become a test platform open to all °ÄÃÅÁùºÏ²Ê¸ßÊÖ partners. WEST stands for W (tungsten) Environment in Steady-state Tokamak.
