A team of engineers at the University of Wisconsin–Madison has discovered a method to significantly reduce the size of thermonuclear reaction chambers.
The special coating improves heat dissipation and also manages to capture neutral hydrogen atoms in the plasma – a key factor in increasing efficiency and preventing premature termination of the reaction. This technological advancement marks the beginning of a new era in fusion reactor design that will see them more compact, efficient and easier to operate.

Coating innovation: a breakthrough for nuclear fusion
In a world in constant search for sustainable and powerful energy sources, the nuclear fusion it has long been considered the Holy Grail of energy. The work of American engineers opens new frontiers in this field, promising smaller but surprisingly more powerful reactors. Their innovative method includes a coating in tantalum, a metal with an exceptionally high melting point, which improves not only heat dissipation, but also the capture of neutral hydrogen atoms.
Tantalum, with its melting point of 3017 ° C, has proven to be essential in this new technology. It was applied to the internal walls of the reactor chamber through a cold metallization process, and on its own it showed very interesting advantages.
Our technology shows notable improvements over current approaches. With this research, we are the first to demonstrate the benefits of using cold spray coating technology for casting applications

“Facilitated” thermonuclear power
The new coating does not simply increase the efficiency of the reactor, but also offers important elements. For example, the ease of application of the tantalum coating makes it particularly useful for in-situ maintenance and repairs, eliminating the need to completely disassemble the chamber. Furthermore, the process of releasing captured hydrogen during heating does not damage the coating, allowing for effective reuse.
The excitement over this discovery is palpable, and further testing is planned in a new experimental reactor under construction in Wisconsin. Confirmation of the results will demonstrate its applicability on a large scale.
This technology could accelerate the adoption of nuclear fusion as a reliable, clean energy source, paving the way for a future where clean energy is within everyone's reach.
