Generation 4 IMSR Fission Technology, A Perfect Fit for Repowering Coal

By Simon Irish

Despite the world’s growing awareness of the scale of climate change and the immense challenge of mitigating it, coal is still a predominant source of power, comprising 27 percent of total global primary energy consumption in 2021, according to the BP Statistical Review of World Energy.

With its roughly 900 grams of CO2-equivalent per kilowatt-hour (gCO2/kWh) life cycle emissions, it is one of the most emissions-intensive forms of electricity generation.

Where Does Terrestrial Energy’s Technology Fit into the UK’s Energy Landscape?

By Mike Drury

“New nuclear” has enjoyed a good start to 2022.

Breakthrough legislation on the financing of new nuclear projects has been followed by warm rhetoric from the Business Secretary, Kwasi Kwarteng, who talked about the need for the UK to “double down on new nuclear power” as “the more clean, affordable power we generate in the UK, the less dependent we’ll be on imports.”

For Government, “Nuclear = energy security.”

This shouldn’t come as a surprise. Nuclear remains the only credible route for the UK to ensure secure, low-carbon, and affordable energy alongside a system based on renewables.

Without nuclear as a large slice of the energy mix, Net Zero looks impossible.

Interest in new technology and what it brings in terms of security of supply, jobs, growth, investment, and IP for UK Plc is therefore high.

Yet not all new nuclear technology is the same.

A missing piece of the Net Zero puzzle

The UK is in danger of missing several pieces of the Net Zero puzzle if it overlooks the immense potential of technologies like Generation IV molten salt reactors with their vast near-term potential to decarbonise industry.

With the cost of energy at record highs for British households, business, and industry we simply cannot rely on a single nuclear technology.

Molten salt has the potential to fill the gaps and support all energy vectors.

Terrestrial Energy’s Integral Molten Salt Reactor (IMSR®) offers flexible, low carbon technology that can deliver high-quality thermal power and electricity both at low cost.

A single IMSR® unit provides 195MW of on-demand, low-carbon electricity that can be ramped up from 50% to 100% in under ten minutes.

The high-quality heat produced by the IMSR® can be distributed over three miles to industry and the residual heat to households as well.

Generation IV Designs Improve the Economics of Nuclear Power

By Simon Irish

Amid rising concerns about how we can decarbonize our whole energy system to address climate challenges, we are seeing greater awareness of nuclear energy’s important role.
