“…A Sodium-Cooled Fast Reactor (SFR) concept is investigated as a representative of advanced reactors with an intermediate (between VHTR and PWR) operating temperature range. The analysis for the SFR is based on the AFR-100 reactor design [72]. A concept of the AFR-100 steam cycle has been developed by Argonne in previous work [73].…”

The feasibility and performance of nuclear energy coupled with Negative Emission Technology (NET) processes were investigated in this report. Three overarching questions from nuclear NET systems guided this research: which NET would be able to use heat and/or electricity from nuclear power plants (NPPs); what is the performance and cost of a nuclear NET system; and what would be the market outlook for this system? Among the various NETs that are actively being developed, several were found to potentially benefit from coupling with an NPP via (1) large amounts of decarbonized and constant-output electricity; (2) free waste heat or cheap low-temperature heat; or (3) high-temperature heat. NPPs were found to be compatible with Direct Air Capture (DAC) systems, and a detailed techno-economic analysis of coupled NPP&DAC systems was performed. Preliminary analysis also indicated that biomass and water-based NETs are potentially compatible with NPPs, but further work is needed to quantify the performance of these nuclear NET systems.Design and performance analyses were completed for both liquid solvent DAC (L-DAC) and solid sorbent DAC (S-DAC) technologies. A 1.0-GWth NPP coupled with L-DAC and S-DAC was found to be able to capture 12-15 Mt CO2/yr and 1.0-1.5 Mt CO2/yr, respectively. While the L-DAC process enables much greater CO2 capture than the S-DAC process when both are sized with a 1 GWth NPP, the NPP&L-DAC system considered also requires >2 GWth natural gas oxy-combustion to reach adequate temperature in the calciner. CO2 generated from natural gas combustion is also captured as part of the calcination process, in addition to the CO2 captured from air, resulting in overall CO2 sequestration of close to 30% more than what is captured from air. The cost of carbon capture calculated with the
