Schematic diagram of fusion power plant

JET and ITER are experiments which are not designed to produced large scale power output for the grid. Construction will probably commence on the first fusion power plants during the 2030s, hence we can only show a schematic here.

JET’s new divertor

Philippe Mertens from Forschungszentrum Jülich is checking the solid tungsten lamellae on four tile modules of the new divertor. This central part of the divertor on the bottom of the vessel will have to withstand the highest heat loads of any component in JET.

The snowflake divertor

The snowflake is not usually associated with extremely high temperatures – yet this image is from the hottest part of a tokamak, the divertor.
