This would forever change our world.

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.

Tokamak Energy.

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’.

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.

We are closer than ever to a world of unlimited energy.

Scientists create the highest plasma pressure ever recorded with the Alcator C-Mod reactor in a breakthrough for clean energy technology.

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.

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.

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.

That’s why researchers are hard at work on ways to make spacecraft power systems more efficient, resilient and long-lasting.

“NASA needs reliable long-term power systems to advance exploration of the solar system,” said Jean-Pierre Fleurial, supervisor for the thermal energy conversion research and advancement group at NASA’s Jet Propulsion Laboratory, Pasadena, California. “This is particularly important for the outer planets, where the intensity of sunlight is only a few percent as strong as it is in Earth orbit.”
