Record neutron numbers at Sandia Labs’ Z machine fusion experiments

Posted by in category: nuclear energy

A relatively new method to control nuclear fusion that combines a massive jolt of electricity with strong magnetic fields and a powerful laser beam has achieved its own record output of neutrons—a key standard by which fusion efforts are judged—at Sandia National Laboratories’ Z pulsed power facility, the most powerful producer of X-rays on Earth.

The achievement, from a project called MagLIF, for magnetized liner inertial fusion, was reported in a paper published Oct. 9 in the journal Physical Review Letters.

“The output in neutrons in the past two years increased by more than an order of magnitude,” said Sandia physicist and lead investigator Matt Gomez. “We’re not only pleased that the improvements we implemented led to this increase in output, but that the increase was accurately predicted by theory.”

New nuclear engine concept could help realize 3-month trips to Mars

Posted by in categories: chemistry, nuclear energy, space travel

Seattle-based Ultra Safe Nuclear Technologies (USNC-Tech) has developed a concept for a new Nuclear Thermal Propulsion (NTP) engine and delivered it to NASA. Claimed to be safer and more reliable than previous NTP designs and with far greater efficiency than a chemical rocket, the concept could help realize the goal of using nuclear propulsion to revolutionize deep space travel, reducing Earth-Mars travel time to just three months.

Because chemical rockets are already near their theoretical limits and electric space propulsion systems have such low thrust, rocket engineers continue to seek ways to build more efficient, more powerful engines using some variant of nuclear energy. If properly designed, such nuclear rockets could have several times the efficiency of the chemical variety. The problem is to produce a nuclear reactor that is light enough and safe enough for use outside the Earth’s atmosphere – especially if the spacecraft is carrying a crew.

According to Dr. Michael Eades, principal engineer at USNC-Tech, the new concept engine is more reliable than previous NTP designs and can produce twice the specific impulse of a chemical rocket. Specific impulse is a measure of a rocket’s efficiency.

Chernobyl fungus could shield astronauts from cosmic radiation

Posted by in categories: chemistry, nuclear energy, space

Will astronauts have fungi shields as protection against radiation in the future? 😃


When astronauts return to the moon or travel to Mars, how will they shield themselves against high levels of cosmic radiation? A recent experiment aboard the International Space Station suggests a surprising solution: a radiation-eating fungus, which could be used as a self-replicating shield against gamma radiation in space.

AL_A reveals plans for world’s first magnetised fusion power plant

Posted by in category: nuclear energy

Amanda Levete’s firm AL_A is partnering with Canadian energy company General Fusion to design a pioneering power plant that will use nuclear fusion.

The prototype plant will act as a demonstration facility for the technology, which uses hydrogen as fuel, with onsite facilities for experts and the general public to visit.

General Fusion wants to transform how the world is energised by replicating the process that powers the sun and the stars,” said AL_A.

‘Quark Fusion’ Could Outperform Nuclear Fusion

Posted by in categories: nuclear energy, particle physics

Circa 2017


In a few decades, we might get all our power from nuclear fusion. Researchers have been working to build functional nuclear fusion reactors, which mimic the fusion reactions that occur in the sun to generate power. Once we figure out fusion power, we could use these generators to power our lives for decades.

This Molten Salt Reactor Is the Next Big Thing in Nuclear

Posted by in category: nuclear energy

It’s fast, cheap, safe, and eats up waste. What’s not to like?


A new molten salt reactor design can scale from just 50 Megawatts electric (MWe) to 1,200 MWe, its creators say, while burning up nuclear waste in the process.

☢️ You like nuclear. So do we. Let’s nerd out over nuclear together.

Impatient? A Spacecraft Could Get to Titan in Only 2 Years Using a Direct Fusion Drive

Posted by in categories: military, nuclear energy, space

Fusion power is the technology that is thirty years away, and always will be – according to skeptics at least. Despite its difficult transition into a reliable power source, the nuclear reactions that power the sun have a wide variety of uses in other fields. The most obvious is in weapons, where hydrogen bombs are to this day the most powerful weapons we have ever produced. But there’s another use case that is much less destructive and could prove much more interesting – space drives.

The concept fusion drive, called a direct fusion drive (or DFD) is in development at the Princeton Plasma Physics Laboratory (PPPL). Scientists and Engineers there, led by Dr. Samuel Cohen, are currently working on the second iteration of it, known as the Princeton field reversed configuration-2 (PFRC-2). Eventually the system’s developers hope to launch it into space to test, and eventually become the primary drive system of spacecraft traveling throughout our solar system. There’s already one particularly interesting target in the outer solar system that is similar to Earth in many ways – Titan. Its liquid cycles and potential to harbor life have fascinated scientists since they first started collecting data on it.

We’ve Long Waited for Fusion. This Reactor May Finally Deliver It—Fast

Posted by in category: nuclear energy

I don’t know how long we’ll continue to have to wait.


Researchers at the Massachusetts Institute of Technology (MIT) are collaborating on a new “compact” fusion reactor that could feasibly be built and go online much faster than existing fusion reactor concepts. Does that mean fusion’s Lucy will finally let an industry Charlie Brown kick the football? Maybe.
