1.7 billion years ago, Earth had a natural nuclear reactor

Posted by in categories: nuclear energy, space

Planets can create nuclear power on their own, naturally, without any intelligence or technology. Earth already did: 1.7 billion years ago.

Posted by in categories: education, Elon Musk, nuclear energy, satellites

Power is life, whether in the void or on another planet far from Earth.
Therefore, the use of nuclear energy and a constant, powerful supply of.
electricity has the potential to speed up, improve, and lower the cost of.
interplanetary travel.
The NASA-supported SpaceX nuclear rocket technology may be the way of.
the future for space travel. It might significantly shorten journey times to far
off locations, improve launch flexibility, and make astronaut safety.
throughout spaceflight. Additionally, it might reduce the likelihood of hostile.
attacks against satellites.
What is this space technology, and how does it work?

Kazakhstan’s first NPP to be an international project

Posted by in categories: economics, nuclear energy, security

“In June, our delegation was in South Korea, in July we went to France. Negotiations are ongoing with Chinese suppliers. Based on the results of an in-depth study of international experience, nuclear technology suppliers will be involved. I repeat, this will be an international project,” he reaffirmed, adding that the results of this experience is under study.

“In principle, the construction of a nuclear power plant is a long process, it takes about eight years. Without nuclear power, we will not be able to ensure energy security for ourselves… We will need such generation — the whole world is moving towards decarbonisation. We must move to clean technologies, and nuclear generation is the answer to the challenge of the times,” he stressed.

He stressed that the safety of NPP operation is of paramount importance. “We will choose the technology that is the safest, and those suppliers who can complete all the work in a timely manner. Related areas of our economy will also develop around this industry. There will be a big positive effect on the development of our country as a whole.”

Nuclear Fusion Is No Longer Science Fiction

Posted by in categories: futurism, nuclear energy

This could modernize the entire power grid with near-limitless energy.

Since scientists first demonstrated nuclear power 70 years ago, the second stage of nuclear power has remained just beyond our fingertips: nuclear fusion power. While promising, the ETA on the technology required to develop and build viable nuclear fusion has remained decades away.

Until now. Probably.

New Magnet is Powerful Enough to Lift an Aircraft Carrier

Posted by in categories: military, nuclear energy

Less than a week after a Bill Gates-backed MIT startup announced it had successfully tested a massive magnet that could allow them to achieve “net energy” with their nuclear fusion reactor, scientists at France’s International Thermonuclear Experimental Reactor (ITER) received the first part of another huge magnet, an AP report explains.

That magnet is so strong that its American manufacturer claims it can lift an aircraft carrier. When it is fully assembled it will be almost 60 feet (20 meters) tall and 14 feet (over four meters) in diameter, and it could be the key to providing practically limitless energy via nuclear fusion.

Want a Good Reason to Capture Carbon Dioxide? — Use It to Power the Electrical Grid

Posted by in category: nuclear energy

Steam turbines could be replaced by pressurized carbon dioxide (CO2) closed-loop systems to spin turbines.

Steam turbines in thermal power generation are today’s standard. But pressurized carbon dioxide (CO2) in a closed-loop system could do the job. Supercritical CO2 acting as both a liquid and a gas under extreme pressure would provide the impetus to spin a turbine. Using supercritical CO2 may prove to be far more efficient than steam to provide emissions-free power to the electrical grid. Energy input coming from renewable sources such as wind, solar, geothermal, as well as nuclear power, or even gas or coal-fired thermal energy power plants with accompanying carbon capture technology could be combined with this technology to be an effective addition to energy utilities.

Recently researchers at the Sandia National Laboratory Kirtland Air Force Base in the United States demonstrated a closed-loop Brayton Cycle engine technology as it delivered power to the electrical grid continuously. Sandia has been working with the Brayton Cycle technology for power generation for some time now because it is seen as having significant energy conversion advantages over conventional steam turbines by as much as 50%.

Ultra Safe Nuclear opens pilot-scale TRISO fuel facility in Oak Ridge

Posted by in category: nuclear energy

Ultra Safe Nuclear Corporation (USNC) celebrated the opening of its Pilot Fuel Manufacturing (PFM) facility in Oak Ridge, Tenn., on August 18 with a ribbon-cutting ceremony and tour attended by assistant secretary for nuclear energy Kathryn Huff, Tennessee lieutenant governor Randy McNally, U.S. Rep. Chuck Fleischmann (R.), representatives from the offices of Sens. Marsha Blackburn (R.) and Bill Hagerty (R.), and other distinguished guests. The next day, radiological operations began at the privately funded facility, which was designed and built in less than twelve months within an existing industrial building purchased by USNC in 2021.

Forecast: Nuclear power in Poland should account for close to 40% of energy mix

Posted by in categories: business, economics, employment, nuclear energy

Nuclear power will be capable of generating 38.4 percent of Poland’s electric power needs by 2043, and should raise the country’s GDP by over 1 percent, a report by the Polish Institute of Economics (PIE) has forecast.

The report, titled “Economic aspects of nuclear investment in Poland — influence on business, the labor market and local communities,” also says that the nuclear energy program will generate 40,000 jobs over the next five decades.

According to the most optimistic scenario, 70 percent of the value of the investments in nuclear energy should be realized by Polish companies, and the total investment realized by them could reach close to $40 billion.

Surprising attractiveness of hurdle to developing safe, clean and carbon-free energy

Posted by in categories: nuclear energy, space

Scientists have discovered the remarkable impact of reversing a standard method for combatting a key obstacle to producing fusion energy on Earth. Theorists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have proposed doing precisely the opposite of the prescribed procedure to sharply improve future results.

Tearing holes in plasma

The problem, called “locked tearing modes,” occurs in all today’s tokamaks, doughnut-shaped magnetic facilities designed to create and control the virtually unlimited fusion power that drives the sun and stars. The instability-caused modes rotate with the hot, charged — the fourth state of matter composed of free electrons and that fuels —and tear holes called islands in the magnetic field that confines the gas, allowing the leakage of key heat.
