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.

NASA — Saw Something Come Out Of A Black Hole For The First Time Ever… — Siamtoo

Posted by in categories: cosmology, nuclear energy

You don’t have to know a whole lot about science to know that black holes normally suck things in, not spew things out. But NASA detected something mighty bizarre at the supermassive black hole Markarian 335. Two of NASA’s space telescopes, including the Nuclear Spectroscopic Telescope Array (NuSTAR), amazingly observed a black hole’s corona “launched” away from the supermassive black hole.

Then an enormous pulse of X-ray energy spewed out. This kind of phenomena has never been observed before.

Three peer-reviewed papers highlight scientific results of National Ignition Facility record yield shot

Posted by in categories: nuclear energy, particle physics

After decades of inertial confinement fusion research, a yield of more than 1.3 megajoules (MJ) was achieved at Lawrence Livermore National Laboratory’s (LLNL’s) National Ignition Facility (NIF) for the first time on Aug. 8, 2021, putting researchers at the threshold of fusion gain and achieving scientific ignition.

On the one-year anniversary of this historic achievement, the scientific results of this record experiment have been published in three peer-reviewed papers: one in Physical Review Letters and two in Physical Review E (See papers one and two). More than 1,000 authors are included in the Physical Review Letters paper to recognize and acknowledge the many individuals who have worked over many decades to enable this significant advance.

“The record shot was a major scientific advance in fusion research, which establishes that fusion ignition in the lab is possible at NIF,” said Omar Hurricane, chief scientist for LLNL’s inertial confinement fusion program. “Achieving the conditions needed for ignition has been a long-standing goal for all inertial confinement fusion research and opens access to a new experimental regime where alpha-particle self-heating outstrips all the cooling mechanisms in the fusion plasma.”

Wind, solar provide 67% of new US electrical generating capacity in first half of 2022

Posted by in category: nuclear energy

Clean energy accounted for more than two-thirds of the new US electrical generating capacity added during the first six months of 2022, according to data recently released by the Federal Energy Regulatory Commission (FERC).

Wind (5,722 megawatts) and solar (3,895 MW) provided 67.01% of the 14,352 MW in utility-scale (that is, greater than 1 MW) capacity that came online during the first half of 2022.

Additional capacity was provided by geothermal (26 MW), hydropower (7 MW), and biomass (2 MW). The balance came from natural gas (4,695 MW) and oil (5 MW). No new capacity was reported for 2022 from either nuclear power or coal.

US Regulators to Certify First Small Modular Nuclear Reactor Design

Posted by in categories: climatology, engineering, nuclear energy, sustainability

View insights.

Since 2016, engineering firm NuScale has been working toward getting approval for a first-of-its-kind nuclear reactor, and late last week, the Nuclear Regulatory Commission (NRC) gave it the green light. The company’s pint-sized nuclear reactor has numerous safety benefits over larger reactors, and the small size makes it possible to build them at a centralized facility before shipping them to their final destination.

Nuclear power seems to flip between savior and boogeyman every few years. As climate change escalates due to the use of fossil fuels, nuclear is seen as a way to reduce carbon emissions while maintaining high electricity generation. However, all it takes is one accident like Fukushima or a reminder that Chernobyl is still incredibly dangerous decades later to make people second-guess the construction of new fission generators.

Meet ‘Copernicus’: TAE’s planned billion-degree, hydrogen-boron nuclear fusion reactor

Posted by in categories: climatology, engineering, nuclear energy, sustainability

TAE’s latest backers include the likes of Google and Chevron

TAE has earned the backing of forward-thinking investors and, so far, has raised a total of $1.2 billion for its commercial fusion development thanks to a track record of exceeding milestones and performance capability. TAE’s mission is to provide a long-term solution to the world’s rapidly increasing electricity demand while ensuring global energy independence and security.

To that end, the company recently closed its Series G-2 financing round, in which it secured $250 million from investors in the energy, technology, and engineering sectors. By avoiding carbon and particulate emissions, TAE’s safe, non-radioactive method minimizes any negative effects on the environment or the effects of climate change.
