Deep Fission (FISN) Company presentation summary

Technology and deployment model

• Gravity Nuclear Reactor uses established pressurized water reactor (PWR) technology deployed one mile underground, leveraging oil, gas, and geothermal drilling methods to enhance safety, reduce surface infrastructure, and lower costs.

• Hydrostatic pressure from a mile-deep water column provides 160 atm of natural pressure for reactor operation, supporting inherent safety and reliability.

• Modular, scalable design targets up to 15 MWe per reactor, with plans for clustered deployments at single sites.

• Utilizes standard low-enriched uranium (LEU) fuel, with interim spent fuel storage integrated into the deployment model.

• Surface infrastructure is minimized, enhancing physical security and resilience against attacks or sabotage.

Market opportunity and regulatory environment

• Growing demand from data centers, AI, and industrial sectors is driving a pipeline of up to 18.5 GWe in non-binding letters of intent.

• U.S. data center power demand is projected to outpace supply, with significant shortfalls expected through 2030.

• Policy tailwinds include accelerated reactor licensing, DOE pilot program participation, and alignment with national decarbonization goals.

• Regulatory pathway leverages DOE demonstration and NRC licensing, with proactive engagement to streamline approvals.

Commercialization and business model

• Revenue streams include reactor delivery, engineering services, technology licensing, operations and maintenance, and electricity sales.

• Build/Own/Operate (BOO) model supports recurring revenue and project-level equity participation.

• Strategic partnerships with Great Plains Development Authority, Blue Owl, and Endeavour enable accelerated deployment in data center and industrial markets.

• Supply chain relationships with Halliburton, Urenco, Day & Zimmermann, and RV Industries support drilling, fuel, construction, and manufacturing.
