How close is nuclear fusion to break-even? If you trust the headlines we’re getting close and the international project ITER is going to be the first to produce energy from fusion power. But not so fast. Scientists have, accidentally or deliberately, come to use a very misleading quantity to measure their progress. Unfortunately we’re much farther away from generating fusion power than the headlines suggest.

Gates’ Startup Replaces Coal Plant With New Kind of Nuclear Reactor

Posted by in categories: climatology, nuclear energy

Editor’s note, 6/28/21, 3:35 PM: The article was updated to clarify that Natrium features a sodium‐cooled fast reactor and not a type of molten salt reactor, as previously reported.

A nuclear power startup founded by Bill Gates has announced plans to build a new kind of nuclear reactor at a retiring coal plant in Wyoming.

This reactor will be the first real-world demonstration of the startup’s technology, which could help power the world — without warming the climate.

Harnessing the Power of the Sun on Earth: Major Advance in Stellarator Performance for Fusion Energy

Posted by in categories: nuclear energy, physics

Stellarators, twisty magnetic devices that aim to harness on Earth the fusion energy that powers the sun and stars, have long played second fiddle to more widely used doughnut-shaped facilities known as tokamaks. The complex twisted stellarator magnets have been difficult to design and have previously allowed greater leakage of the superhigh heat from fusion reactions.

Now scientists at the Max Planck Institute for Plasma Physics (IPP), working in collaboration with researchers that include the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL

The U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) is a collaborative national laboratory for plasma physics and nuclear fusion science. Its primary mission is research into and development of fusion as an energy source for the world.

Nuclear waste interaction in the environment may be more complicated than once thought

Posted by in categories: chemistry, nuclear energy

Past and present nuclear activities (energy, research, weapon tests) have increased the urgency to understand the behavior of radioactive materials in the environment. Nuclear wastes containing actinides (e.g. plutonium, americium, curium, neptunium…) are particularly problematic as they remain radioactive and toxic for thousands of years.


Lawrence Livermore National Laboratory (LLNL) scientists and collaborators proposed a new mechanism by which nuclear waste could spread in the environment.

The new findings, that involve researchers at Penn State and Harvard Medical School, have implications for nuclear waste management and environmental chemistry. The research is published in the Journal of the American Chemical Society.

Rolls-Royce Is Developing a Nuclear Reactor for Mining the Moon and Mars

Posted by in categories: Elon Musk, nuclear energy, space travel

The firm is looking into how a micro-nuclear reactor could be used to propel rockets while in space at huge speeds and how that technology could then be redeployed to provide energy for drilling, processing, and storage for “Moon mining” and possibly “Mars mining.”

Dave Gordon, head of the company’s defense division, said this work is possible thanks to Jeff Bezos and Elon Musk and their respective space companies.

He added that’s Rolls-Royce is the only company on the planet that does mechanical, electrical, and nuclear and a full end-to-end lifecycle of nuclear capability. He also noted that the firm could use its experience in developing nuclear-powered submarines for the Royal Navy for 60 years to apply what it learned to spacecraft since submarines and spacecraft are somewhat similar.

The Race for Fusion Power Heats Up as Multiple Projects Hit New Milestones

Posted by in category: nuclear energy

Fusion power could be a silver bullet for the world’s energy and environmental woes, but it’s famously always 30 years away. A recent flurry of announcements is raising hopes that maybe the timeline has started to tighten.

The technology has huge potential because it promises to generate enormous amounts of energy from abundant fuel that can be cheaply extracted from seawater. On top of that, the process doesn’t create any long-lived radioactive waste, unlike conventional nuclear power plants.

The catch is that finding a way to contain the same reaction that powers the sun here on Earth is no easy feat. Now, though, MIT spinout Commonwealth Fusion Systems (CFS) has taken a significant step in that direction after carrying out the first tests of a magnet that can reach a field strength of 20 teslas, the highest ever achieved on Earth.

Fukushima plant failed to probe cause of faulty filters

Posted by in categories: law, nuclear energy

TEPCO has been repeatedly criticized for coverups and delayed disclosures of problems at the plant. In February, it said two seismometers at one reactor had remained broken since last year and failed to collect data during a powerful earthquake.


TOKYO (AP) — Officials at Japan’s wrecked Fukushima nuclear power plant have acknowledged they neglected to investigate the cause of faulty exhaust filters that are key to preventing radioactive pollution, after being forced to replace them twice.

Representatives of the operator, Tokyo Electric Power Company Holdings, made the revelation Monday during a regular review of the Fukushima Daiichi plant at a meeting with Japanese regulatory authorities. Three reactors at the plant melted following a massive earthquake and tsunami in 2011.

U.S. Regulators Approve Texas Nuclear Dump Despite Opposition

Posted by in category: nuclear energy

A similar nuclear waste storage project, proposed in New Mexico by Holtec International Corp., is also awaiting approval by the Nuclear Regulatory Commission. The agency said it expects to make a decision on that proposal in January 2022.


Texas officials vowed to fight a federal regulator’s decision to approve plans to allow thousands of tons of highly radioactive nuclear waste to be stored in oil fields in the state.
