Integration of Heat-only Small Modular Reactor with Thermally Driven Systems

Popis výsledku v původním jazyce

The nuclear small modular reactor (SMR) technologies represent potential competitive carbon-free solutions for replacing fossil fuel-based energy generation. In addition to several SMR technologies designed for electricity generation, some others, like Teplator, are under development for district heating applications. As the heating demand fluctuates over time, using the excess heat during the low demand periods could enhance the load following flexibility, capacity factor, and the economics of the integrated system. Depending on the output temperature of the nuclear plant, the excess heat could be used for different secondary applications. This study aims to investigate the options as secondary thermally driven applications to be integrated with heat-only reactors such as the solar chimney concept, thermoelectric tubes, Kalina cycle and organic Rankine cycle technologies for low-temperature electricity generation and other heat-driven systems like water desalination and hydrogen production. The calculations are based on a typical heat-demand profile, where the overall efficiency and secondary products are roughly estimated for different candidate integrations. This study concludes that the hot water temperature generated by SMRs plays an essential role in the performance of the secondary heat-driven outputs. Therefore, further studies seem required to model the tradeoff between costs, SMR’s output temperature, and overall system performance in order to achieve an optimized integrated system.
