Dispatchable energy
Unlike wind and solar, nuclear power plants and hydropower offer dispatchable energy, meaning they are able to adjust their output to meet electricity demand. Additionally, the expanded use of nuclear power for non-electric applications, including district heating, hydrogen production, desalination and heat for industrial processes, offers further options to reduce emissions.
To support this increasing nuclear energy demand, the IAEA is actively assisting countries by providing technical expertise and capacity building to help them establish or expand nuclear power plants.
Integrated Nuclear Infrastructure Reviews (INIR) are an example where the IAEA assists countries to assess the status of their national infrastructure as they embark on establishing nuclear power plants. INIR missions enable countries to engage in discussions and receive guidance from experts about recommendations and best practices in nuclear power infrastructure development.
These missions ensure that the infrastructure necessary for the safe, secure and sustainable use of nuclear power is developed and implemented in a responsible and orderly manner.
In 2009, the IAEA conducted the first INIR Mission to a country initiating the use of nuclear power. Since then, INIR missions have been hosted by various states including the United Arab Emirates, that has successfully established the Barakah Nuclear Energy Plant. This year, it is expected to supply around 25 per cent of the UAE’s electricity, up from its current contribution of 20 per cent, reducing the country’s carbon emissions by 22 million tonnes annually.
Similarly, countries like Sweden, France and Finland have utilized nuclear energy combined with hydro and renewables to largely decarbonize their electricity production. France has an extremely low level of CO2 emissions from electricity generation, since over 90 per cent of its electricity is from low-carbon sources, 70 per cent of that from nuclear power. And 94 percent of Sweden’s electricity comes from low carbon sources in Sweden with more than a third coming from nuclear, according to the IEA.
