US-based fusion technology company Type One Energy Group plans to locate to the Tennessee Valley Authority’s (TVA) Bull Run Fossil Plant in Clinton, Tennessee to build a stellarator fusion prototype machine in collaboration with TVA and the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL). TVA's Bull Run Fossil Plant closed on 1 December 2023.Type One says construction of the prototype, Infinity One, could begin in 2025, following the completion of necessary environmental reviews, partnership agreements, required permits, and operating licences.

After successful recommissioning in autumn 2022, the Wendelstein 7-X stellarator fusion device at Germany's Max Planck Institute for Plasma Physics (IPP) has achieved some significant breakthroughs. In 2023, an energy turnover of 1 gigajoule was targeted, but researchers have now achieved 1.3 gigajoules. Moreover, a new record for discharge time was achieved, with the hot plasma maintained for eight minutes.

Two newly announced North American initiatives aim to accelerate the deployment of fusion technologies for power generation. In Canada, Bruce Power, General Fusion, and the Nuclear Innovation Institute (NII) will work together to evaluate potential deployment of a fusion power plant in Ontario. Meanwhile, scientists at the Princeton Plasma Physics Laboratory (PPPL) are teaming up with Renaissance Fusion America as part of a US programme to speed the development of fusion energy.

The US Department of Energy (DOE) on 8 June announced $6.4 million in funding for US scientists to carry out seven research projects at two major fusion energy facilities located in Germany and Japan. These collaborations enable US researchers to explore critical science and technology issues at the frontiers of magnetic fusion research using the unique capabilities of the most advanced overseas research facilities.

IPP said installation of new water-cooled inner cladding of the plasma vessel will make the Wendelstein 7-X facility suitable for higher heating power and longer plasma pulses.

The new cladding’s centrepiece, the so-called divertor, was manufactured by the institute’s Garching branch. It was delivered to Greifswald on 17 March and installation work will last until well into next year.

Fusion systems of the stellarator type promise high-performance plasmas in continuous operation. Accordingly, heat and particles from the hot plasma permanently stress the vessel walls. It is the task of the divertor – a system of specially equipped baffle plates to which the particles from the edge of the plasma are magnetically directed – to regulate the interaction between plasma and wall.

The upgrade of the world's largest stellarator-type fusion device - Germany's Wendelstein 7-X - is set to enter a new stage with the final delivery of components for the so-called divertor. Preparations for installation of the water-cooled inner cladding components have been completed, with installation work expected to continue well into next year.

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.
