50-milliwatt Water Boiler reactor went critical at Los Alamos National Laboratory. It held about 20 ounces of uranium dissolved in a water-filled, 12-inch sphere. It was the first nuclear reactor to use enriched uranium, and the first critical assembly built at the lab.
A new system could generate usable oxygen and fuel from lunar soil
Performed by Moxie — the Mars Oxygen In-Situ Resource Utilization Experiment — the strategy definitely incited hope for extraterrestrial survival. Future human missions could take versions of Moxie to Mars instead of carrying oxygen from Earth to sustain them.
But, Moxie is powered by a nuclear battery onboard.
“In the near future, we will see the crewed spaceflight industry developing rapidly,” said Yingfang Yao, a material scientist at Nanjing University.
Long-awaited accelerator ready to explore origins of elements
The Facility for Rare Isotope Beams (FRIB) at Michigan State University (MSU) in East Lansing had a budget of $730 million, most of it funded by the US Department of Energy, with a $94.5 million contribution from the state of Michigan. MSU contributed an additional $212 million in various ways, including the land. It replaces an earlier National Science Foundation accelerator, called the National Superconducting Cyclotron Laboratory (NSCL), at the same site. Construction of FRIB started in 2014 and was completed late last year, “five months early and on budget”, says nuclear physicist Bradley Sherrill, who is FRIB’s science director.
For decades, nuclear physicists had been pushing for a facility of its power — one that could produce rare isotopes orders of magnitude faster than is possible with the NSCL and similar accelerators worldwide. The first proposals for such a machine came in the late 1980s, and consensus was reached in the 1990s. “The community was adamant that we need to get a tool like this,” says Witold Nazarewicz, a theoretical nuclear physicist and FRIB’s chief scientist.
Russia’s Attack on Ukraine is Making Everything on this Planet Worse
James McCall SpringerHmmm… So quantum computing systems aren’t close to being perfected BUT they’re being used for ransomware attacks?
Is “bleepingcomouter” a bs sensationalist media producer like Futurism?
Len Rosen shared a link.
The “special operation” as Russia calls it has come with a threat of nuclear war, and consequences for food and energy security for many.
Nuclear expert cautions against unfamiliar new nuclear age
High-tech advances in weapons technologies and a return of ‘great power nuclear politics’, risk the world ‘sleepwalking’ into a nuclear age vastly different from the established order of the Cold War, according to new research undertaken at the University of Leicester.
Andrew Futter, Professor of International Politics at the University of Leicester, makes the warning in a research paper for the Hiroshima Organization for Global Peace (HOPe), published today (Friday).
While stockpiles are much reduced from the peak of up to 70,000 nuclear weapons seen in the 1980s, progress in a number of new or ‘disruptive’ technologies threatens to fundamentally change the central pillars on which nuclear order, stability and risk reduction are based.
Scientists Turn Nuclear Waste Into Diamond Batteries That Could Last For Thousands Of Years
Crossrail, or the Elizabeth Line, is set to revolutionize London transport, with high-speed trains running from east to west underneath the UK capital.
Thermophotovoltaic “Heat Engine” Design Could Change the Future of Power Grids
There are so many paths we humans are running down in our chase for a greener future it’s extremely hard to keep track of everything. The auto industry is trying to go electric, either by means of batteries or hydrogen, the aviation industry is going for biofuels, while energy production and storage, well, this one is all over the place, betting on anything from the sun to the wind and nuclear.
