Jeff Bezos Is Backing an Ancient Kind of Nuclear Fusion

Posted by in categories: finance, nuclear energy

This tech could be more practical than tokamaks.

Two competing nuclear fusion companies, each with venture capital superstars as major investors, say we’re approaching the “Kitty Hawk moment” for their technology as early as 2025.

Shoot for the Moon: Its Surface Contains a Pot of Gold

Posted by in categories: biotech/medical, military, nuclear energy, terrorism

Here’s a riddle: What do the Moon, nuclear weapons, clean energy of the future, terrorism, and lung disease all have in common?

The answer is helium-3, a gas that’s extremely rare on Earth but 100 million times more abundant on the Moon.

The capability to show anatomic details of the lungs and airways, and the ability to display functional imaging as a patient breathes, makes helium-3 MRI far better than the standard method of testing lung function. Called spirometry, this method tells physicians how the lungs function overall, but does not home in on particular areas that may be causing a problem. Plus, spirometry requires patients to follow instructions and hold their breath, so it is not great for testing young children with pulmonary disease.

Scientists gain an unprecedented view of irradiated nuclear fuel

Posted by in categories: materials, nuclear energy

In a feat requiring perseverance, world-leading technology, and no small amount of caution, scientists have used intense X-rays to inspect irradiated nuclear fuel. The imaging, led by researchers at Purdue University and conducted at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, revealed a 3D view of the fuel’s interior structure, laying the groundwork for better nuclear fuel designs and models.

Until now, examinations of uranium fuel have been limited to mostly surface microscopy or to various characterization techniques using mock versions that possess little radioactivity. But scientists want to know at a deeper level how the material changes as it undergoes fission inside a . The resulting insights from this study, which the Journal of Nuclear Materials published in August 2020, can lead to that function more efficiently and cost less to develop.

Storm in a cosmic teacup: A new paradigm for understanding plasma turbulence

Posted by in categories: nuclear energy, physics, space

On the path to writing his Ph.D. dissertation, Lucio Milanese made a discovery—one that refocused his research, and will now likely dominate his thesis.

Milanese studies , a gas-like flow of ions and electrons that comprises 99 percent of the visible universe, including the Earth’s ionosphere, interstellar space, the , and the environment of stars. Plasmas, like other fluids, are often found in a turbulent state characterized by chaotic, unpredictable motion, providing multiple challenges to researchers who seek to understand the cosmic universe or hope to harness burning plasmas for fusion energy.

Milanese is interested in what physicist Richard Feynman called “the most important unsolved problem of classical physics”—turbulence. In this case, the focus is plasma turbulence, its nature and structure.

Meet the father of the hydrogen-boron laser fusion reactor

Posted by in category: nuclear energy

Circa 2020 radiationless laser.

One of the world’s leading specialists in laser fusion, the Australian physicist Prof. Heinrich Hora, has proposed a new type of nuclear reactor which promises to provide highly-efficient, radioactivity-free generation of electric power, with virtually unlimited reserves of fuel. The design uses ultra-high-power, ultra-short-pulsed lasers to trigger fusion reactions between nuclei of hydrogen and boron. Hora believes that a prototype of his reactor could be running within the decade.

In the previous installments of this series, Jonathan Tennenbaum introduced readers to the new reactor concept and its fascinating scientific and technological background.
