DataFor:Conceptual design and optimization of cogeneration system based on small modular lead-cooled fast reactor

Cogeneration system based on Small Modular Lead-cooled Fast Reactor (SMLFR)becomes attractive due to its good characteristics of flexible location, safety, thermal efficiency, and economy. The conventional cogeneration systems using coal,gas, or renewable energy as the thermal resource have lower thermal performanceas compared to LFR based cogeneration systems due to lack of sustainable energyresources. A modified concept design of cogeneration system based on a 35-MWthSMLFR has been proposed to improve the thermal performance. A new concept ofDistrict Heating (DH) structure layout along with optimization based on the exhauststeam/water drainage position. The thermodynamic model based on energy and exergy methods has been used to design and calculate the energy losses of the cogeneration system components. The energy utilization rate can be increased significantlyby optimizing the DH. The thermal efficiency of the proposed system reaches up to73.64% with an increase of 3.51% and the exergy efficiency reaches up to 59.31%with an increase of 5.01%. The increase of thermal performance under the differentheating demands will lead to better energy conservation and environmental safety.This study can be further used as the reference for the design and optimization ofSMLFR cogeneration system based on thermodynamic and exergy analysis.
