‘Diamond-age’ of power generation as nuclear batteries developed

Posted by in categories: nuclear energy, physics

New technology has been developed that uses nuclear waste to generate electricity in a nuclear-powered battery. A team of physicists and chemists from the University of Bristol have grown a man-made diamond that, when placed in a radioactive field, is able to generate a small electrical current.

Canadian design review for StarCore HTGR

Posted by in categories: nuclear energy, particle physics

Canadian reactor designer StarCore Nuclear has applied to the Canadian Nuclear Safety Commission (CNSC) to begin the vendor design review process for its Generation IV high temperature gas reactor (HTGR).

Montréal-based StarCore, founded in 2008, is focused on developing small modular reactors (SMRs) to provide power and potable water to remote communities in Canada. Its standard HTGR unit would produce 20 MWe (36 MWth), expandable to 100 MWe, from a unit small enough to be delivered by truck. The helium-cooled reactor uses Triso fuel — spherical particles of uranium fuel coated by carbon which effectively gives each tiny particle its own primary containment system — manufactured by BWXT Technologies. Each reactor would require refuelling at five-yearly intervals.

StarCore describes its reactor as “inherently safe”, with a steep negative thermal coefficient which eliminates the possibility of a core meltdown. The use of helium — which does not become radioactive — as a coolant means that any loss of coolant would be “inconsequential”, the company says. The reactors would be embedded 50 metres underground in concrete silos sealed with ten-tonne caps.

Engineering Fusion Energy By 2025

The world needs abundant, clean energy. Nuclear fusion — with no CO2 emissions, no risk of meltdown and no long-lived radioactive waste — is the obvious solution, but it is very hard to achieve.

The challenge is that fusion only happens in stars, where the huge gravitational force creates pressures and temperatures so intense that usually repulsive particles will collide and fuse; hence “fusion”. On Earth we need to create similar conditions, holding a hot, electrically-charged plasma at high enough pressure for long enough for fusion reactions to occur. The scientific and engineering challenges behind putting a star in a box are large, to say the least. Without proper confinement of the plasma, the reaction would stop. The plasma must be isolated from the walls of the reactor — a feat that can be performed most effectively by magnets. The most advanced machine for this purpose is the ‘tokamak’.

I-Team: Nuclear reactor test in Nevada could make a Mars trip reality

Posted by in categories: nuclear energy, space

This story may sound like the plot of a science-fiction movie.

Next year, a team of top scientists will hunker down inside a classified facility in the Nevada desert so they can experiment with a piece of advanced technology.

The test will focus on a small nuclear reactor and if it works as planned, it could be a huge step toward putting humans on Mars.

Limitless Energy: MIT Set a New Record for Nuclear Fusion

Posted by in category: nuclear energy

In Brief:

  • MIT researchers using the Alcator C-Mod reactor have achieved a new nuclear fusion pressure record of more than 2 atmospheres of pressure.
  • The Alcator C-Mod is set to retire after over 23 years of use but its nuclear fusion experiments have brought us closer to nearly unlimited clean energy.

For the first time, scientists have measured sun’s real-time energy

Posted by in categories: nuclear energy, physics

Physicists on the Borexino neutrino experiment at Italian physics laboratory INFN in Gran Sasso announced in Nature that they have detected neutrinos produced deep inside the sun.

Neutrinos, which constantly stream through us, interact very rarely with other matter. When created in nuclear reactions inside the sun, they fly through dense solar matter in seconds and can reach the Earth in eight minutes.

Physicists Propose A Way to Make Magnetic Fields That Are Stronger Than Any on Earth

Posted by in categories: nuclear energy, physics

In Brief:

Researchers have proposed an alternative way to generate super-strong magnetic fields that would solve the hindrances keeping us from harnessing the Faraday effect to its full use. More research and experimentation are needed to test the method.
