General Atomics (GA) of the USA and Tokamak Energy of the UK have agreed to collaborate in the area of high temperature superconducting (HTS) technology for fusion energy and other industry applications. Meanwhile, Germany's Max Planck Institute for Plasma Physics will work with Proxima Fusion to further develop the stellarator concept.

Scientists at Germany’s Max Planck Institute for Plasma Physics (IPP) on 25 June reported a new record performance at the Wendelstein 7-X stellerator, which began operation in 2015. Earlier experiments saw the plasma in the reactor achieve higher temperatures and densities than ever before, and now the records have been broken again in a new test with upgraded components. Like the tokamak, the stellarator uses large superconducting magnets to suspend hydrogen plasma and heat it to the temperatures and pressures needed to fuse hydrogen into helium. The Wendelstein 7-X has 50 superconducting magnet coils some 3.5 metres high. However, while the tokamak confines plasma in a doughnut shaped torus, the stellarator traps the plasma in a twisting spiral shape, which is designed to cancel out instabilities in the suspended plasma.

The third and largest consignment of Russian equipment for the international thermonuclear experimental reactor (Iter) was deliovered to the seaport of St Petersburg on 7 September for further transportation to the site of the reactor in Cadarache (France) via Hamburg, Germany. The equipment, weighing 85 tonnes, includes: aluminium water-cooled direct-current buses for the poloidal field, the central solenoid and correcting winding power systems; thermal expansion joints and other parts of the DC bus systems that connect the superconducting windings of the tokamak electromagnetic system with their power supply sources; as well as sections of operational resistors for plasma discharge initiation systems.

The Korean Superconducting Tokamak Advanced Research (KSTAR), a tokamak nuclear fusion reactor, achieved a world record of 70 seconds in high-performance plasma operation, South Korea's National Fusion Research Institute (NFRI) said in a statement on 14 December. NFRI said a fully non-inductive operation mode - a "high poloidal beta scenario" - had been used to achieve this long and steady state of operation using a high-power neutron beam. It said various techniques, including a rotating 3D field, had been applied to alleviate the accumulated heat fluxes on the plasma-facing components.
