Sustainable Clean Energy

Truly innovative reactor technology like the IMSR® will play a critical role in achieving a clean, sustainable and prosperous world

To meet the world’s energy demands while avoiding greenhouse gas emissions, a clean energy alternative is needed that is cost-competitive with fossil fuels and easily deployable. IMSR® technology fulfills that goal and is poised to play a key role in the clean energy future.

Fossil fuels represent 85 percent of global primary energy supply, but they are not clean. Clean-energy technologies we use today cannot displace them because of limitations:

  • Fossil fuels: Capture and sequestration technologies are not cost-competitive.
  • Variable renewables (Wind and Solar): These are intermittent, requiring a storage breakthrough or fossil fuel back up, a large expansion in grid infrastructure, and their further expansion implies improbable scenarios for the mining of critical elements and minerals.
  • Conventional reactor power plants: These are scalable and clean, but new-build power plants using conventional reactor technology are difficult to finance, take too long to construct, and are often not cost-competitive with fossil fuels, particularly natural gas.

To meet our climate goals, we need to produce more energy while decreasing greenhouse gas emissions.Advanced reactor technologies, such as those used in the IMSR®, have no such limitations and will play a key role in our clean energy future.

“The next energy miracle is nuclear energy.”Bill Gates

Many countries aim to reduce emissions by 80 percent by 2050, and many forecast that this is not possible without nuclear energy. Experts agree nuclear energy must play a critical role in our energy future, but conventional nuclear technology is insufficient to meet that promise.

Advanced reactors such as the IMSR® represent a step-change improvement. They avoid the many drawbacks of conventional reactor power plants.

Nuclear Is Clean Energy

The life cycle emissions of greenhouse gases from nuclear power plants are among the lowest of all energy sources – IMSR® nuclear plants are virtually emission-free on a life cycle basis.

IMSR® power plants use energy from uranium fission, which is 10 million times more energy dense than fossil fuels. IMSR® power plants have among the lowest environmental impacts of clean energy technologies today.

The IMSR® is a transformative energy technology. It is a cost-competitive clean energy alternative that can produce heat and power without greenhouse gases at great scale, and in the time necessary to achieve 2050 environmental targets.

Nuclear Is Sustainable

With current extraction methods and reactor uses, uranium resources will last centuries.

Future evolution of IMSR® technology could include use of spent nuclear fuel, “breeding” fuel cycles, and even thorium. With these iterations, IMSR® nuclear power becomes near-infinitely sustainable as an energy resource, one that can meet the majority of global energy needs for many centuries.
