According to the United States Energy Information Administration, the amount of energy supplied by all fuel sources across the world is tremendous: 155,481 teraWatt-hours as of 2014, the latest year on record.

In order to meet this enormous energy demand in a given year, we need to burn 24 billions tonnes of coal, or 12 billion tonnes of oil, or a bit less of natural gas (10.4 billion tonnes).That's for fossil fuels.

If we were to use only conventional nuclear energy to power the world, we would need to consume approximately 7,000 tonnes of nuclear fuel (enriched uranium or mixed oxyde).

However with nuclear fusion, only 867 tonnes of hydrogen would suffice...

The WEST project is based on an upgrade of the Tore Supra tokamak, in operation since 1988 in France (CEA- IRFM).

With its new tungsten divertor WEST has become a test bed for ITER, capable of testing ITER high heat flux component technologies in relevant plasma conditions. 

Following the commissioning of its sub-systems, WEST has had a short shutdown period during which the ICRH antenna was installed and other machine optimization activities carried out. Plasma experiments should resume in October.

The European Domestic Agency has successfully tested prototypes of a specific type of magnetic diagnostic sensor at the Belgian SCK-CEN and the Czech REZ laboratories.

The diagnostic sensor prototypes, based on Low-Temperature Co-fired Ceramic (LTCC) technology, responded well to neutron exposure. Data collected throughout the experimentation will help engineers optimize the sensors' final design.

The diagnostic LTCC sensors measure the magnetic field around the plasma core and yield vital information regarding its position and shape. Of the more than 1,500 magnetic field sensors of various different types required on ITER, the LTCC-based sensors will be most exposed to neutrons.

The prototypes were manufactured by EPFL (Switzerland), Via Electronic (Germany) and VTT (Finland).
