In 2019, the International Energy Agency (IEA) released Nuclear Power in a Clean Energy System, which highlights the importance of nuclear power in decarbonizing the world’s energy sector. The paper notes: “For advanced economies, nuclear has been the biggest low-carbon source of electricity for more than 30 years, and it has played an important role in the security of energy supplies in several countries. But it now faces an uncertain future as ageing plants begin to shut down in advanced economies, partly because of policies to phase them out but also under pressure from market conditions and regulatory barriers.”
Despite the importance of nuclear power as a low-carbon source of electricity, some countries have been phasing it out, citing risks such as the 1986 Chernobyl disaster and the 2011 Fukushima disaster.

To be clear, nuclear power will face headwinds as long as the public perceives that such risks still exist. That’s why it is important to highlight technology developments that can eliminate fears of the major nuclear disasters we have seen in the past.
The first generation of nuclear power plants were built in the 1950s and 1960s and were based on light water reactor technology. These reactors use water as a coolant and neutron moderator, and require enriched uranium as fuel.
Second-generation reactors, which were developed in the 1970s and 1980s, improved on the design of first-generation reactors but still use water as a coolant and require enriched uranium fuel.
Third-generation reactors, which began to be deployed in the 1990s and 2000s, incorporate passive safety features and other design improvements, but still use water as a coolant.
Fourth-generation nuclear power refers to a new class of advanced nuclear reactors that are designed to be safer, more efficient, and more sustainable than previous generations of nuclear power plants. These reactors incorporate advanced materials, designs, and cooling systems, and are intended to be more economical, flexible, and scalable than current nuclear technology.

Compared to earlier generations of nuclear power plants, fourth-generation reactors have several advantages.
First, they are much safer, with inherent safety features that prevent the release of radioactive materials in the event of an accident or malfunction. Second, they are more efficient, with higher conversion rates of nuclear fuel to electricity. Third, they are more sustainable, with lower waste production and the ability to use nuclear waste as fuel. Finally, they are more flexible and scalable, with the potential to be used in a variety of applications and settings, including remote locations and microgrids.
Terrestrial Energy is a Canadian-based company working on fourth-generation nuclear technology. The company’s Integral Molten Salt Reactor (IMSR) is a Generation IV nuclear reactor that uses molten salt as a coolant and fuel carrier.
