World’s top supercomputer to simulate nuclear reactors

Posted by in categories: military, nuclear energy, supercomputing

The supercomputer which is under construction is 50 times more powerful that existing supercomputer at the facility.

The world’s most powerful supercomputer, Aurora, is being set up in the US to help scientists at the Argonne National Laboratory (ANL) simulate new nuclear reactors that are more efficient and safer than their predecessors, a press release said.

The US is already home to some of the world’s fastest supercomputers, as measured by TOP500. These supercomputers can be tasked with a variety of computational roles. Last month, Interesting Engineering reported how the Los Alamos National Laboratory (LANL) planned to use a supercomputer to check nuclear stockpiles for the US military.

Alfvén waves: unlocking unlimited clean energy for the Earth

Posted by in categories: nuclear energy, particle physics

Researchers of the Princeton Plasma Physics Laboratory (PPPL) announced the discovery of a promising approach to mitigate the damaging effects of runaway electrons in tokamak fusion devices in a statement.

The key to this discovery lies in harnessing a unique type of plasma wave known as Alfvén waves, named after the renowned astrophysicist Hannes Alfvén, a Nobel laureate in 1970.

Alfvén waves have long been recognized for their ability to loosen the confinement of high-energy particles within tokamak reactors— a type of fusion reactor that confines plasma in the shape of a donut using a magnetic field.

Coming Soon: Portable Poop-Powered Nuclear Reactors?

Posted by in categories: military, nuclear energy


DARPA is our favorite source for off-the-wall yet compelling technology. We’ve seen proposals for flying cars, handheld nuclear fusion devices, and now poop-powered nuclear reactors. It’s not as crazy at seems.

Wired explains that there would be multiple benefits to sticking portable, poop-powered reactors at military bases. The reactors could eliminate human waste (and the need to dispose of it) at the same time as they reduce the need to scrounge up pricey fuel sources. And since people never stop pooping, potential fuel is virtually limitless.

The Ghostly Glow of a Nuclear Power Station Was Detected in Pure Water 150 Miles Away

Posted by in categories: nuclear energy, particle physics, space

Back in 2018, a tank of the purest water, buried under kilometers of rock in Ontario, Canada, flashed as barely detectable particle slammed through its molecules.

It was the first time that water has been used to detect a particle known as an antineutrino, which originated from a nuclear reactor more than 240 kilometers (150 miles) away. This incredible breakthrough promises neutrino experiments and monitoring technology that use inexpensive, easily acquirable and safe materials.

As some of the most abundant particles in the Universe, neutrinos are odd little things with a lot of potential for revealing deeper insights into the Universe. Unfortunately they are almost massless, carry no charge, and barely interact with other particles at all. They mostly stream through space and rock alike, as though all matter was incorporeal. There’s a reason they’re known as ghost particles.

Microsoft wants small nuclear reactors to power its AI and cloud computing services

Posted by in categories: business, climatology, nuclear energy, robotics/AI

Bill Gates is a staunch advocate for nuclear energy, and although he no longer oversees day-to-day operations at Microsoft, its business strategy still mirrors the sentiment. According to a new job listing first spotted on Tuesday by The Verge, the tech company is currently seeking a “principal program manager” for nuclear technology tasked with “maturing and implementing a global Small Modular Reactor (SMR) and microreactor energy strategy.” Once established, the nuclear energy infrastructure overseen by the new hire will help power Microsoft’s expansive plans for both cloud computing and artificial intelligence.

Among the many, many, (many) concerns behind AI technology’s rapid proliferation is the amount of energy required to power such costly endeavors—a worry exacerbated by ongoing fears pertaining to climate collapse. Microsoft believes nuclear power is key to curtailing the massive amounts of greenhouse emissions generated by fossil fuel industries, and has made that belief extremely known in recent months.

[Related: Microsoft thinks this startup can deliver on nuclear fusion by 2028.].

Chi-Nu experiment ends, bolsters nuclear security and energy reactors

Posted by in categories: nuclear energy, physics, security

The results of the Chi-Nu physics experiment at Los Alamos National Laboratory have contributed essential, never-before-observed data for enhancing nuclear security applications, understanding criticality safety and designing fast-neutron energy reactors. The Chi-Nu project, a years-long experiment measuring the energy spectrum of neutrons emitted from neutron-induced fission, recently concluded the most detailed and extensive uncertainty analysis of the three major actinide elements—uranium-238, uranium-235 and plutonium-239.

“Nuclear and related nuclear chain reactions were only discovered a little more than 80 years ago, and experimenters are still working to provide the full picture of fission processes for the major actinides,” said Keegan Kelly, a physicist at Los Alamos National Laboratory. “Throughout the course of this project, we have observed clear signatures of fission processes that in many cases were never observed in any previous experiment.”

The Los Alamos team’s final Chi-Nu study, on the isotope uranium-238, was recently published in Physical Review C. The experiment measured uranium-238’s prompt fission spectrum: the energy of the neutron inducing the fission—the neutron that crashes into a nucleus and splits it—and the potentially wide-ranging energy distribution (the spectrum) of the neutrons released as a result. Chi-Nu focuses on “fast-neutron-induced” fission, with incident neutron energies in millions of electron volts, where there have typically been very few measurements.
