District heat with Small Modular Reactors (SMR)

Research output: Book/ReportReport


Small Modular Reactors (SMR)a re small nuclear reactors with fast construction time. First have been already built and many other concepts will follow soon. SMRs can replace fossil fuels in district heat production and in industry steam production for both high and low temperature heat. One NuScale SMR unit could fit to the Espoo district heating system with high utilization ratio. The estimated payback time would be from 10 to 20 years depending on assumed costs and prices.
