Iter transformer in place as materials tests continue

​

As the first of three Chinese-supplied electrical transformers is installed at the Iter fusion project in France, researchers in the Netherlands are testing the resistance to neutron radiation of materials that will shield the fusion reactor's core.

​

Dutch radioisotope producer NRG announced that material to be used in Iter's "first wall" will be irradiated in its High Flux Reactor (HFR) at Petten over the coming months. The plasma in which Iter's nuclear fusion reaction will take place at a temperature of 150 million degrees Kelvin is itself contained by a magnetic field. The first wall provides the first shielding of the reactor's core and will be exposed to the high-energy neutrons produced in the fusion process, which are not contained by the magnetic field.
