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.
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.
The invasion that Russia has wrongfully started in Ukraine has led to more people talking about the threat of Nuclear war and World War 3. How does the Doomsday Clock relate to all this?
Script: Since 2020, the Doomsday Clock has been set to 100 seconds to midnight. Which is the closest its ever been to midnight in its 75 years of existence. As the scientists who set the clock put it: we’re “at doom’s doorstep.”
The Doomsday Clock is a metaphor to remind humans how close we are to destroying our planet through the technology we develop, with midnight representing the apocalypse. It’s a symbol to remind us to address these dangers so that we can survive on our planet. It was created by the Bulletin of the Atomic Scientists, an organization founded by scientists at the University of Chicago who worked on the Manhattan Project, which was America’s effort to develop atomic weapons during the Cold War.
When the Doomsday Clock debuted in 1947, its creator, artist Martyl Langsdorf, set it to 7 minutes to midnight. She was married to a physicist who worked on the Manhattan Project. When she heard him and other scientists talk about the consequences of developing this dangerous technology, she created the clock to show that we didn’t have much time left to get atomic weapons under control.
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 plasma — the fourth state of matter composed of free electrons and atomic nuclei that fuels fusion reactions —and tear holes called islands in the magnetic field that confines the gas, allowing the leakage of key heat.
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.
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.”
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.
Scientists achieved the first case of nuclear fusion ignition in a lab. The milestone would help them improve the source of generating electricity and energy. Continue reading to know more.
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.
NuScale, which has been anticipating approval of this design since the last technology review in 2020, says its small modular reactor (SMR) addresses these concerns. It’s based on a “Multi-Application Small Light Water Reactor” developed at Oregon State University in the early 2000s. It has a compact uranium nuclear core along with helical coil steam generators inside the same steel reactor vessel. So, it generates power through the same mechanism as a traditional reactor (no fancy uranium or thorium salts here), but each SMR only produces about 50 MWe (megawatts electrical) compared with 1,000 or more in existing reactor designs.
