Can SMRs supply both power and heat?

Question

Accepted Answer

Small Modular Reactors Can Supply Both Electricity and Heat

Small Modular Reactors (SMRs) are designed to provide both electricity and heat, catering to a diverse range of energy needs across power and non-power sectors. Their capacity output, defined as 300 MW or less, allows for flexibility in deployment, and they can generate temperatures ranging from 285°C to over 850°C. This broad temperature spectrum enables SMRs to be utilized for various industrial processes beyond simple electricity generation, including direct heating applications.
Diverse Temperature Outputs for Specific Applications

The temperature range achievable by SMRs is a key differentiator for their application. Generation III+ SMR designs, for instance, can typically deliver process heat at approximately 320°C. In contrast, advanced Generation IV SMR designs are engineered to achieve much higher temperatures, targeting up to 950°C. This capability makes them suitable for industries that require significant thermal energy for their operations.
Suitability for High-Temperature Industrial Processes

Higher temperature reactors, encompassing technologies like liquid metal, molten salt, and gas-cooled reactors, are particularly well-suited for energy-intensive industries. These include sectors such as petroleum refining, steelmaking, and the production of synthetic fuels. Furthermore, these advanced reactors are also designed to facilitate the high-temperature electrolysis required for green hydrogen production, a critical component for decarbonizing heavy transport and chemical manufacturing.
Applications for Lower-Temperature Needs

Conversely, SMRs based on light water reactor (LWR) technology, which operate at lower temperatures, are ideal for different applications. These include providing heat for district heating systems, which supply warmth to residential and commercial buildings, and for desalination processes, converting seawater into fresh water. This demonstrates the versatility of SMR technology in addressing both industrial and community-based energy demands.
