Researchers at the International Thermonuclear Experimental Reactor debuted the first part of a massive magnet they’ll use to build a fusion reactor.
Our partners at UK Atomic Energy Authority and Createc brought Spot to Sellafield Ltd to demonstrate how Spot can automate nuclear inspections, support decommissioning, and reduce risk for people in hazardous environments. Watch the full video: https://bit.ly/3ttOgcr
What we need now is an expansion of public and private investment that does justice to the opportunity at hand. Such investments may have a longer time horizon, but their eventual impact is without parallel. I believe that net-energy gain is within reach in the next decade; commercialization, based on early prototypes, will follow in very short order.
But such timelines are heavily dependent on funding and the availability of resources. Considerable investment is being allocated to alternative energy sources — wind, solar, etc. — but fusion must have a place in the global energy equation. This is especially true as we approach the critical breakthrough moment.
If laser-driven nuclear fusion is perfected and commercialized, it has the potential to become the energy source of choice, displacing the many existing, less ideal energy sources. This is because fusion, if done correctly, offers energy that is in equal parts clean, safe and affordable. I am convinced that fusion power plants will eventually replace most conventional power plants and related large-scale energy infrastructure that are still so dominant today. There will be no need for coal or gas.
Circa 2014
Scientists researching nuclear energy have made a breakthrough in nuclear fusion with an experiment that generated more fuel than was put in.
It was a moment three years in the making, based on intensive research and design work: On Sept. 5 for the first time, a large high-temperature superconducting electromagnet was ramped up to a field strength of 20 tesla, the most powerful magnetic field of its kind ever created on Earth. That successful demonstration helps resolve the greatest uncertainty in the quest to build the world’s first fusion power plant that can produce more power than it consumes, according to the project’s leaders at MIT and startup company Commonwealth Fusion Systems (CFS).
That advance paves the way, they say, for the long-sought creation of practical, inexpensive, carbon-free power plants that could make a major contribution to limiting the effects of global climate change.
Fusion reactors will use abundant sources of fuel, will not leak radiation above normal background levels, and will produce less radioactive waste than current fission reactors. Learn about this promising power source.
The chernobyl special industrial zone — ecosystem restoration, remediation, and the development of energy and chemical byproducts — mykola tolmachov, chernobyl-51 industrial cluster.
The Chernobyl disaster / nuclear accident, occurred on April 26th, 1,986 at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of Ukraine.
NuScale Power, the startup specializing in the design of small modular nuclear reactors, has published new data concerning the production capacities of its NuScale Power Module (NPM). Thanks to the 25% increase in power output of an NPM, each NuScale module is now capable of producing 2,053 kg/hour of hydrogen, or nearly 50 metric tons per day.
Just one NuScale Power Module can produce 77 MWe of carbon-free electricity to power 60,000 homes in the U.S. NuScale’s flagship power plant design can house up to 12 modules for a total gross output of 924 MWe. The 924 MWe that a 12-module NuScale plant produces is enough to power nearly 700,000 homes with clean, reliable energy.

Housed at Lawrence Livermore National Laboratory, the US$3.5-billion facility wasn’t designed to serve as a power-plant prototype, however, but rather to probe fusion reactions at the heart of thermonuclear weapons. After the United States banned underground nuclear testing at the end of the cold war in 1,992 the energy department proposed the NIF as part of a larger science-based Stockpile Stewardship Program, designed to verify the reliability of the country’s nuclear weapons without detonating any of them.
With this month’s laser-fusion breakthrough, scientists are cautiously optimistic that the NIF might live up to its promise, helping physicists to better understand the initiation of nuclear fusion — and thus the detonation of nuclear weapons. “That’s really the scientific question for us at the moment,” says Mark Herrmann, Livermore’s deputy director for fundamental weapons physics. “Where can we go? How much further can we go?”
Here Nature looks at the NIF’s long journey, what the advance means for the energy department’s stewardship programme and what lies ahead.
