Terrestrial Energy to Sponsor Sustainable Investment Forum in NYC

TerrestrialForumSocialmediaImageThe first UN general assembly following the COP21 Climate Change Summit in Paris, France last December will be held in New York City this September as part of Climate Week.

Climate week runs September 19th-26th, and one of the marquee events will be the Sustainable Investment Forum, sponsored in part by CNA Member, Terrestrial Energy.

This is a global opportunity for the nuclear community to come together and show the world how we can help contribute to a cleaner environment.

Terrestrial Energy Says Molten Salt is the Future of SMR Technology

Terrestrial Energy is on the path to commercializing its Integral Molten Salt Reactor (IMSR), which it says holds the greatest promise as an alternative to conventional energy sources.

“We believe we have a technology that is ideal for the small modular reactor market,” said Simon Irish, chief executive of Terrestrial Energy, based in Toronto. “We believe our technology will provide industry with a small modular reactor that provides power which is simply more convenient and more cost competitive than using coal.”

Global energy demand will grow substantially over the next generation, driven primarily by population growth and industrialization in Asia. Many countries seek secure, cost-competitive energy sources that avoid the climate-changing greenhouse gases generated by coal, natural gas and oil.

“The need for game-changing innovation is far, far stronger this decade than decades before,” said Irish. “We face many problems identifying secure, safe and economically competitive energy supplies over the next two decades. Solving that problem with existing approaches is probably not practical.”

The molten-salt reactor system differs fundamentally from today’s water-cooled commercial reactors. Instead of using solid uranium as fuel, it dissolves the uranium in liquid salt mix. Irish said the technique gives the molten-salt reactor a unique safety profile.

“You can’t lose primary coolant because your fuel and your coolant are one and the same,” Irish explained, “and they are not under pressure as they are in traditional solid-fuel reactors.  The IMSR system is passively safe – meaning safety is assured even in the absence of backup power.”

Although the molten-salt reactor is not yet commercially available, it uses a recognized, proven nuclear technology demonstrated in the late 1950s to the 1970s by the illustrious Oak Ridge National Laboratory in Tennessee.

The trick is to change a working laboratory reactor into a reactor suitable for industry – and that’s where Innovation comes in.

Building on the Oak Ridge demonstrations, Terrestrial Energy has developed a reactor system that appears simple, safe to operate, convenient and highly cost effective for industry.  It could enter service early next decade.

“The first step on our path to commercialization involves the manufacturing and construction of our first commercial reactor at a site in Canada, and obtaining a license to operate it from the CNSC,” explains Irish. “We intend to have it up and running and connected to the grid by early next decade.”

Technologies Take a While to Turn the World Around

By John Stewart
Director, Policy and Research
Canadian Nuclear Association

Asked in the 1970s about the influence of the French Revolution on western civilization, Chou En Lai is said to have paused and replied: It’s too soon to tell.

You might say the same thing about nuclear technology’s impact on the world.  Sure, we’ve had it for about 70 years. But is that long enough for a fair test?

Newcomen

Practical steam engines were in use for a century before they really changed most people’s worlds.

Steam engines were first commercialized around the year 1700 to pump water out of mineshafts (which they did better than humans), and shortly thereafter to drive textile mills (which they did better than waterwheels).

They weren’t successfully applied to transportation (steamboats and locomotives) until just after 1800. Before they could operate on these mobile platforms, steam engines had to get smaller, lighter, safer, more applicable, and far more efficient.

When they did this, steam engines dramatically reduced transport costs. That made the world a very different place in the nineteenth century – and in many ways, and for many people, a much better one.

Coalbrookdale
The Trevithick locomotive, circa 1803.

A recent announcement by Mississauga-based Terrestrial Energy Inc. (TEI) reminds us again that we’ve probably not even glimpsed where revolutionary reactor designs might take society in a carbon-constrained world.

Remember, we’ve come less than six decades from the opening of the first utility-scale nuclear generating station – which operated successfully in Pennsylvania from 1957 until 1982.

Reactor technology has spent those decades generating cleaner and cheaper electricity than nearly any other source, and probably doing it more safely than any other source. But that’s not the end of the story.

Because reactor technology has also spent those decades getting better and better.

A number of CNA member companies have designs that reflect this progress, and that could change our children’s and grandchildren’s world in very positive ways. Terrestrial’s is just one example of this.

On January 7, Terrestrial Energy announced a collaboration with the U.S. Department of Energy’s Oak Ridge National Laboratory to advance the design of its concept for an integral molten salt reactor (IMSR). Oak Ridge is where early molten salt reactors were proven, decades ago.

More recent Molten Salt Reactor technology could represent a revolution in nuclear safety, waste and proliferation resistance, and in energy cost-competitiveness. Terrestrial’s is a small modular design, with models ranging from as small as 80 MWth – about one-tenth of the typical utility-scale reactor installed today.

The company wants to start commercial deployment of IMSRs by early next decade. Edge-of-grid and off-grid locations in Canada, many of them currently using dirty, expensive diesel generators, could benefit dramatically from these or other advanced and smaller reactor designs.

Think nuclear had its heyday in the 1960s? Sure. And the piston engine was just a better way to get water out of coal mines.
