Nanotechnology and Fusion Energy: Unlocking the Power of the Sun with Japan’s JT-60SA
12 min readThe world is in search of a sustainable and clean energy source to replace the traditional fossil fuels that have been the backbone of industrialization and economic growth for centuries. Two promising technologies, nanotechnology and fusion energy, are at the forefront of this quest. In this article, we will explore how these technologies intersect and the role Japan’s JT-60SA plays in unlocking the power of the Sun.
To the untrained eye, the JT-60SA, located in Naka, northeast of Tokyo, looks like a contraption from a 1970s sci-fi movie. With its tangle of pipes and pumps leading to a metal pot the size of a five-storey building, it is a far cry from the sleek and modern designs we have come to expect from cutting-edge technology. But beneath its unassuming exterior lies a doughnut-shaped vessel where experiments are conducted at millions of degrees, with the potential to unlock a carbon-free, inexhaustible, and safe power source for the future: nuclear fusion.
Fusion energy, the power behind the Sun and the stars, has been a great prize for energy research for decades. Not only is it free from greenhouse gases and free from long-lived nuclear waste, but it is compact, doesn’t cover the whole landscape, and can generate industrially useful quantities of power. Unlike fission, the technique currently used in nuclear power plants, fusion involves combining two atomic nuclei instead of splitting one, generating vast amounts of energy. The process is safe and there are no nasty by-products like fissile material for a nuclear weapon or hazardous radioactive waste that takes thousands of years to degrade.
The JT-60SA, which took 15 years to build, is 15.5 meters tall and 13.7 meters wide, comprising a so-called tokamak vessel able to contain swirling plasma heated to millions of degrees. Inside the facility, the aim is to get nuclei of hydrogen isotopes to fuse into an atom of helium, releasing energy, and mimicking the process that takes place inside the Sun and stars. With only one gram of a mixed fuel, we can obtain an energy equivalent to eight tonnes of oil.
Despite decades of efforts, the technology remains in its infancy and is very expensive. The JT-60SA is the little brother and guinea pig of the International Thermonuclear Experimental Reactor (ITER) being built in France. The holy grail of both projects, as well as others around the world, is to develop technology that releases more energy than is needed to fuel it—and at a large scale and for a sustained period. The feat of “net energy gain” was managed in December 2022 at the National Ignition Facility at Lawrence Livermore National Laboratory in the United States, home to the world’s largest laser.
Magnetic confinement, and in particular, tokamaks, of the kind that JT-60SA is, are much more applicable to running a steady state power plant, to steady energy production as we would need. This is not just a flash in a can. Nanotechnology plays a crucial role in this endeavor by providing materials and structures that can withstand the extreme conditions inside the tokamak and improve the efficiency of the fusion reaction.
Nanotechnology is the engineering of materials, devices, and systems at the nanoscale, which is between 1 and 100 nanometers. The unique properties of materials at the nanoscale can be harnessed to create advanced materials and devices with enhanced performance. In the context of fusion energy, nanotechnology is used to create materials that can withstand the high temperatures and pressures inside the tokamak, as well as improve the efficiency of the fusion reaction.
One such material is carbon nanotubes, which have exceptional thermal and electrical conductivity, making them ideal for use in the heating and current drive systems inside the tokamak. Carbon nanotubes can also be used to create membranes that can separate the plasma from the walls of the tokamak, reducing the amount of energy lost due to the interaction between the plasma and the walls.
Another application of nanotechnology in fusion energy is in the area of tritium breeding, which is the production of tritium, a hydrogen isotope, inside the tokamak. Tritium is a crucial component of the fusion reaction and is currently sourced from natural reserves, which are limited and expensive. By using nanotechnology to create materials that can efficiently breed tritium inside the tokamak, we can reduce our reliance on natural reserves and make fusion energy more economically viable.
The intersection of nanotechnology and fusion energy is a promising area of research that holds the key to unlocking a clean and sustainable energy source for the future. Japan’s JT-60SA, with its doughnut-shaped vessel and experiments conducted at millions of degrees, is a crucial step in this direction. By harnessing the unique properties of materials at the nanoscale, we can create advanced materials and structures that can withstand the extreme conditions inside the tokamak and improve the efficiency of the fusion reaction. The future of energy production lies in the intersection of these two technologies, and Japan’s JT-60SA is leading the way.
In conclusion, the quest for a sustainable and clean energy source to replace fossil fuels has led us to the promising technologies of nanotechnology and fusion energy. Japan’s JT-60SA, with its doughnut-shaped vessel and experiments conducted at millions of degrees, is a crucial step in unlocking the power of the Sun through nuclear fusion.
