Description
Description | Deep Fission Inc. has selected its first three sites for co-development in Texas, Utah and Kansas. The company specializes in placing small modular pressurized water reactors in boreholes one mile underground using a proprietary reactor design. The surrounding geology provides natural shielding and passive containment. The company aims to streamline supply chains by relying on off-the-shelf components and low-enriched uranium, enhancing safety, security, minimizing surface footprint, and lowering costs. The cost model forecasts a 70% to 80% overnight installed cost advantage compared to conventional nuclear technologies, with an estimated levelized cost of electricity of $0.05 to $0.07 per kilowatt-hour. |
