Norway-based marine group Ulstein has introduced Thor, its concept design for a 149-m (489-ft) replenishment, research and rescue (3R) ship powered by a thorium Molten Salt Reactor (MSR) that can be used to recharge battery-driven cruise ships at sea.
-
While stellarator fusion reactors have conventionally featured irregularly shaped magnetic coils, scientists have now developed simpler and straighter versions they say can offer some important benefits.
-
The US Department of Defense has announced that its Strategic Capabilities Office will go ahead with its plan to build and test a small nuclear reactor capable of being moved, and delivering between 1 - 5 MW of power for a minimum of three years.
-
Although nuclear power remains controversial, new reactors are being built in surprising numbers and these will provide the second largest share of the world’s carbon-free energy. It's also an industry undergoing rapid change as new technology comes on line. So, what will nuclear power look like in the decades to come?
-
A UK company says it's demonstrated fusion in record time, on a shoestring US$59 million budget, using an innovative new approach that embeds fuel pellets in tiny, falling cube targets, then shoots projectiles at them at 19 times the speed of sound.
-
A new technology representing a "revolutionary change" in how magnets are made for tokamak reactors could form a key piece of the nuclear fusion power puzzle, by facilitating the type of sustained streams of plasma needed for it to become a reality.
-
DeepMind has lent its AI know-how to the quest for nuclear fusion. Through a partnership with scientists at EPFL, the company has developed an AI algorithm that can generate control strategies to create and maintain different plasma configurations.
-
Scientists at the Joint European Torus (JET) tokamak reactor have smashed the world record for fusion plasma energy output, using the experimental device to generate 59 megajoules of energy in a landmark moment in the quest for nuclear fusion.
-
For the prospect of limitless, clean energy produced through nuclear fusion to become a reality, scientists need the reactions at the heart of the technology to become self-sustaining, and newly published research has edged them closer to that goal.
-
Unless you're really into trivia about gas lanterns and the mantles that make their light so bright, you've probably never heard of thorium, but you may hear a lot more about it in the future. This unassuming metal could one day rival uranium as the nuclear fuel of choice.
-
A UK company with lofty aspirations around sustainable space travel has test-fired a rocket engine powered in part by plastic waste. Pulsar Fusion's ambitious plans also involve the development of nuclear fusion technology for high-speed propulsion.
-
A popular design in the pursuit of fusion power is the tokamak and an exciting example of these donut-shaped reactors can be found at the Korea Institute of Fusion Energy, where a new record for maintaining super-hot plasma has reportedly been set.
