Type One energy has announced its intention to use a retired TVA coal plant site, the Bull Run Fossil Plant in Oak Ridge, Tennessee, as the site for a prototype fusion reactor with the hope to eventually commercialize fusion power – and maybe even find a neat way to use old EV batteries to help power the process. The Bull Run Fossil Plant was a coal-powered generation facility first opened in 1967 and shut down on December 1, 2023 – just over two months ago. It was run by the Tennessee Valley Authority (TVA), the largest public utility in the...

Looking down the barrel of the First Light Fusion’s “Big Friendly Gun” – a two-stage gas gun that's used to generate fusion reactions by the impact of a high-velocity projectile on a specially-designed target. Photo: First Light Fusion In my discussion (published starting here) with Paul Methven, head of Britain’s STEP program to build a first electricity-producing fusion power plant, Methven stressed that the program is open to more than one technological option. While STEP is betting mainly on the spherical tokamak, it is supporting the formation of a “fusion cluster” that will include private fusion companies pursuing entirely different...

Scientists have been chasing the dream of harnessing the reactions that power the Sun since the dawn of the atomic era. Interest, and investment, in the carbon-free energy source is heating up. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For the better part of a century now, astronomers and physicists have known that a process called thermonuclear fusion has kept the Sun and the stars shining for millions or even billions of years. And ever since that discovery, they’ve dreamed of bringing that energy source down to Earth and using it to power the modern world. It’s a dream that’s only become more compelling today, in...

A group of U.S. scientists say they have repeated their landmark energy feat - a nuclear fusion reaction that produces more energy than is put into it. But this time, they say the experiment produced an even higher energy yield than one in December...the lab "won't be discussing further details" of the July experiment until after more analysis.

Canada’s plans to make nuclear power a central part of its decarbonization strategy are taking shape with major announcements around large nuclear builds, small modular reactors and medical isotopes.. Nuclear power accounts for around 15% of Canada’s electricity generation with most capacity in Ontario where some 40% of the population resides. A total of 19 reactors provide around 13.6 gigawatts (GW) across the country, though most are in the provinces of Ontario and New Brunswick, which are 60% and 36% powered by nuclear respectively. ... increasingly vocal support for urgent greenhouse-gas-emission reduction have helped bring the government back to nuclear...

Nuclear power has its pros and cons. Right now, the U.S. seems to be embracing its advantages. Last month, Georgia Power announced that its Vogtle Unit 3 reactor has safely reached 'initial criticality.' “A reactor achieves criticality when the nuclear fission reaction becomes self-sustaining,” the company said in a statement. “Achieving initial criticality is necessary to continue the startup of the Unit in order to generate sufficient heat for the production of electricity.” Nuclear Regulatory Commission spokesperson Scott Burnell told CNBC that this marked the first nuclear reactor to achieve initial criticality since May 2016. Georgia Power expects Vogtle Unit...

Molten Salt Reactors enjoy 15 minutes of fame 11 June 2014   Print Email   A next-generation fast breeder reactor design is gaining popularity in research circles.On 6 June, UK researchers Jasper Tomlinson and Trevor Griffiths won £75,000 in Technology Strategy Board funding (including £20,000 of contributions-in-kind) to carry out an eight-month feasibility study.The project, which will be managed by mechanical engineer Rory O'Sullivan, aims to develop a ranking of alternatives and configurations of a liquid-fuelled molten-salt reactor, including costs, regulatory, public acceptance and site issues for building and licensing a pilot-scale demonstration reactor in the UK. It would...

It’s a good thing that the Biden administration corruptly shut down the Trump administration’s attempt to stop Communist China from spying on us, manipulating us and robbing us blind to avoid offending anyone… like Beijing. “We have heard concerns from the civil rights community that the “China Initiative” fueled a narrative of intolerance and bias. To many, that narrative suggests that the Justice Department treats people from China or of Chinese descent differently. The rise in anti-Asian hate crime and hate incidents only heightens these concerns.” Goodbye China Initiative and U.S. National Security. At least 154 Chinese scientists who worked...

A new round of nuclear fusion experiments for an advanced superconducting tokamak (EAST), or “Chinese artificial sun,” kicked off at the Hefei Institutes of Physical Science this month, Xinhua News Agency reported on Tuesday. According to the institute’s vice director, Song Yuntao, the experiment is aimed at upgrading the EAST auxiliary heating system to make the artificial sun “hotter” and more “durable.” The testing is expected to last for a half year.

This cut-away rendering of the MIT nuclear battery concept shows important components such as the instrumentation and control module, the reactor, and the power module. Credit: Massachusetts Institute of Technology ===================================================================================== We may be on the brink of a new paradigm for nuclear power, a group of nuclear specialists suggested recently in The Bridge, the journal of the National Academy of Engineering. Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery,...

Plutonium is generally thought of as an artificial element created by humans, primarily to make the pits of nuclear weapons, but naturally occurring plutonium can be found in ancient rocks. Plutonium 244 is the longest lived isotope of Plutonium, but it's not easy to make, and finding this specific isotope in interstellar dust grains laid down on the ocean floors tells us important things about the formation of the elements that make up the Earth.Based on this paper:60Fe and 244Pu deposited on Earth constrain the r-process yields of recent nearby supernovae A.

SPARC could be the first fusion reactor to produce net energy—10 years before ITER and in a machine 10 times smaller. A startup chasing the dream of plentiful, safe, carbon-free electricity from fusion, the energy source of the Sun, has settled on a site, timetable, and key technology for building its compact reactor. Flush with more than $200 million from investors, including Bill Gates’s Breakthrough Energy, 3-year-old Commonwealth Fusion Systems announced today that later this year it will start to build its first test reactor, dubbed SPARC, in a new facility in Devens, Massachusetts, not far from its current...

"We are sidestepping all of the scientific challenges that have held fusion energy back for more than half a century," says the director of an Australian company that claims its hydrogen-boron fusion technology is already working a billion times better than expected.

Mini nuclear stations can be mass manufactured and delivered in chunks on the back of a lorry, which makes costs more predictable. Rolls-Royce is leading a consortium to build small modular reactors (SMRs) and install them in former nuclear sites in Cumbria or in Wales. Ultimately, the company thinks it will build between 10 and 15 of the stations in the UK. They are about 1.5 acres in size - sitting in a 10-acre space. That is a 16th of the size of a major power station such as Hinkley Point. SMRs are so small that theoretically every town could...

The War Zone has been reporting on a set of bizarre patents assigned to the U.S. Navy that describe radical new technologies that could absolutely revolutionize the aerospace field, and frankly, the very way we live our lives. These include high-energy electromagnetic fields used to create force fields and outlandish new methods of aerospace propulsion and vehicle design that basically read as UFO-like technology. You can learn all about these patents, their viability, and the issues surrounding them in these exclusive features of ours. Now, the same mysterious Naval Air Warfare Center Aircraft Division engineer behind those patents has produced...

Typically when referring to electrical current, an image of electrons moving through a metallic wire is conjured. Using the spin Seebeck effect (SSE), it is possible to create a current of pure spin (a quantum property of electrons related to its magnetic moment) in magnetic insulators. However, this work demonstrates that the SSE is not limited to magnetic insulators but also occurs in a class of materials known as paramagnets. Since magnetic moments within paramagnets do not interact with each other like in conventional ferromagnets, and thus do not hold their magnetization when an external magnetic field is removed, this...

NASA just tested the tiny nuclear reactor it could use for a Martian colony By Mark Austin — Posted on January 20, 2018 5:41 pm NASA and the Department of Energy have just tested a small fission nuclear reactor named KRUSTY (Kilowatt Reactor Using Stirling Technology) in the Nevada desert — a possible power source for future space exploration or even a manned mission to Mars. Reuters reports that initial testing of the system components in a vacuum environment, part of NASA’s Kilopower project, have led to plans for a full-power test in March. “The Kilopower test program will give...

The finding that fission releases huge amounts of energy launched a scientific and military race to understand and use this new atomic source of power Over Christmas vacation in 1938, physicists Lise Meitner and Otto Frisch received puzzling scientific news in a private letter from nuclear chemist Otto Hahn. When bombarding uranium with neutrons, Hahn had made some surprising observations that went against everything known at the time about the dense cores of atoms—their nuclei. Meitner and Frisch were able to provide an explanation for what he saw that would revolutionize the field of nuclear physics: A uranium nucleus could...

Sweden said on Friday it would phase out some taxes on nuclear power and build new reactors to replace aging plants and secure energy supplies for decades to come. Nuclear power providers in Sweden have said they would be forced to shut the country's loss-making nuclear reactors unless a tax on nuclear capacity is abolished, risking a spike in electricity prices and energy shortages for industry. "The aim is ... to make sure we can always guarantee electricity at competitive prices, in a stable and sustainable way, both in the short and long term," Energy Minister Ibrahim Baylan told reporters....
