Work halted for 10 days when loose bolt is found in San Onofre radioactive waste canister

Posted by in category: nuclear energy

Works crews transferring spent fuel at the San Onofre nuclear plant from cooling pools into dry storage discovered a loose bolt inside one of the canisters, prompting Southern California Edison to temporarily halt the relocation effort. The job resumed earlier this week.

Russian Scientists Are Devising a Plan to Nuke Asteroids

Posted by in categories: nuclear energy, physics, space

You may have thought, “Hey, if we’re threatened by an incoming asteroid, we should just nuke it!” You’re not alone: a team of Russian scientists are working on a plot to do so, by detonating miniature asteroids in a lab.

In fact, several groups of researchers are now toying with the idea of asteroid nuking for the sake of planetary defense. The Russian team has even calculated about how much firepower they’d need to perform such a feat.

According to the translated paper published in the Journal of Experimental and Theoretical Physics: “Given the scale factor and the results of laboratory experiments, the undeniable destruction of a chondritic asteroid 200 m in diameter by a nuclear explosion with an energy above 3 Mt was shown to be possible.”

Scientists zap tiny wires with lasers to create mini-nuclear fusion

Posted by in categories: nanotechnology, nuclear energy

A step towards limitless energy? reactions at record efficiency…


Researchers from Colorado State University’s (CSU) Advanced Beam Laboratory used a compact but powerful laser they built from scratch to heat tiny, invisible wires, known as nanowires.

These contained a source of deuterium, one of two stable isotopes of hydrogen and a common source of fuel for nuclear fusion reactions.

Nanowire-zapping lasers unlock micro-scale nuclear fusion efficiency record

Posted by in categories: nanotechnology, nuclear energy, particle physics

Researchers at Colorado State University (CSU) have broken the efficiency record for nuclear fusion on the micro-scale. Using an ultra-fast, high-powered tabletop laser, the team’s results were about 500 times more efficient than previous experiments. The key to that success is the target material: instead of a flat piece of polymer, the researchers blasted arrays of nanowires to create incredibly hot, dense plasmas.

We have nuclear fusion to thank for our very existence – without it, the Sun wouldn’t have fired up in the first place. Inside that inferno, hydrogen atoms are crushed and through a series of chain reactions, eventually form helium. In the process, tremendous amounts of energy are released. Theoretically, if we can harness that phenomenon we could produce an essentially unlimited supply of clean energy, and although breakthroughs have been made in recent years, nuclear fusion energy remains tantalizingly out of reach.

View on Nuclear Fusion: a Moment of Truth

Posted by in categories: nuclear energy, physics

Fusion technology promises an inexhaustible supply of clean, safe power. If it all sounds too good to be true, that’s because it is. For decades scientists struggled to recreate a working sun in their laboratories – little surprise perhaps as they were attempting to fuse atomic nuclei in a superheated soup. Commercial fusion remains a dream. Yet in recent years the impossible became merely improbable and then, it felt almost overnight, technically feasible. For the last decade there has been a flurry of interest –and not a little incredulity –about claims, often made by companies backed by billionaires and run by bold physicists, that market-ready fusion reactors were just around the corner.


Until recently the attractions and drawbacks of nuclear fusion reactors were largely theoretical. Within a decade this will not be the case.

This Strange Species That Lives Off Nuclear Energy Is Like Alien Life on Earth

Posted by in categories: alien life, nuclear energy

When you’re trying to figure out what alien life might look like, it makes sense to be looking in the most extreme environments Earth has available.

One such place where life has been found to thrive is three kilometres (1.86 miles) beneath the ground, the home of one of the strangest lifeforms we know: the bacterium Desulforudis audaxviator.

It lives in complete dark, in groundwater up to 60 degrees Celsius (140 Fahrenheit) — an environment devoid of sunlight, oxygen or organic compounds.

Scientists observe a new quantum particle with properties of ball lightning

Posted by in categories: climatology, nuclear energy, particle physics, quantum physics

Scientists at Amherst College and Aalto University have created, for the first time a three-dimensional skyrmion in a quantum gas. The skyrmion was predicted theoretically over 40 years ago, but only now has it been observed experimentally.

In an extremely sparse and cold , the physicists have created knots made of the magnetic moments, or spins, of the constituent atoms. The knots exhibit many of the characteristics of , which some scientists believe to consist of tangled streams of . The persistence of such knots could be the reason why ball lightning, a ball of plasma, lives for a surprisingly long time in comparison to a lightning strike. The new results could inspire new ways of keeping plasma intact in a stable ball in fusion reactors.

‘It is remarkable that we could create the synthetic electromagnetic knot, that is, quantum ball lightning, essentially with just two counter-circulating electric currents. Thus, it may be possible that a natural ball lighting could arise in a normal ,’ says Dr Mikko Möttönen, leader of the theoretical effort at Aalto University.
