Holtec International has completed the fabrication and delivery of the Centre Stack Casing for the Princeton Plasma Physics Laboratory's National Spherical Torus Experiment-Upgrade, a precursor to commercial nuclear power based on nuclear fusion.

A poloidal field coil - the largest component being produced in Russia for the multinational fusion project - has completed its journey to the International Thermonuclear Experimental Reactor construction site in France.

Tokamak Energy is to build a prototype compact spherical tokamak, the ST80-HTS, at the UK Atomic Energy Authority's Culham Campus, near Oxford, England. The fusion device - with power plant-relevant magnet technology - will demonstrate multiple technologies required for the delivery of clean, sustainable fusion energy.

Materials with better resilience to the extreme conditions in fusion energy power plants are to be developed in a new partnership between the UK Atomic Energy Authority and the University of Birmingham. UKAEA will also sponsor a Chair in Fusion Materials at the University.

Tokamak Energy of the UK announced it has built a world-first set of new generation high temperature superconducting magnets to be assembled and tested in fusion power plant-relevant scenarios.

The UK Atomic Energy Authority and First Light Fusion have signed an agreement for the design and construction of a facility to house the company's new net energy gain demonstrator, Machine 4, at the authority's Culham Campus in Oxfordshire.

Construction of General Fusion's Fusion Demonstration Plant at the UK Atomic Energy Authority's Culham Campus near Oxford, England, is expected to start later this year following the granting of planning permission by the South Oxfordshire District Council Planning Committee.

The International Thermonuclear Experimental Reactor fusion project has given a progress update on tackling the defects discovered last year in the thermal shields and vacuum vessel sector. It hopes to tender for the thermal shield work, and have a contractor in place, by the end of March.

Tokamak Energy has signed an agreement with Japan's Furukawa Electric to supply "several hundred kilometres" of specialist high temperature superconducting tape for its ST80-HTS prototype fusion device.

A new mode of improved plasma confinement has been demonstrated at the Experimental Advanced Superconducting Tokamak, the Hefei Institutes of Physical Science, Chinese Academy of Sciences announced. It said the new high-confinement and self-organising Super I-mode "represents the reliability and advancement of the machine itself but also offers insights into how to better maintain the plasma operating stably and for long duration".

The first ever controlled fusion experiment to produce more energy from fusion than the laser energy used to drive it was conducted at the National Ignition Facility at the Lawrence Livermore National Laboratory on 5 December - a breakthrough that has been decades in the making.

The UK Atomic Energy Authority and the UK Satellite Applications Catapult have partnered to demonstrate how advanced remote handling and robotics technology developed for fusion energy research can be used to provide maintenance for in-orbit satellites.
