On the other hand, nuclear power can offer a reliable source of carbon-free energy. However, the massive scale of building reactors means that projects get delayed, and cost overruns are common. These shortcomings are being addressed through innovations such as small modular reactors (SMR) that can be up to a tenth of the size of a conventional nuclear reactor and can be built in factories.
Each module of an SMR can produce up to 300 MWe (megawatt equivalent) of energy and has advanced safety features.
