Deep Fission Publishes DOE-Approved Safety Design for Underground Reactor
Event summary
- Deep Fission published its DOE-approved Nuclear Safety Design Agreement (NSDA) for the Gravity™ pilot reactor, a voluntary transparency move.
- The NSDA outlines safety frameworks, design requirements, and regulatory engagement for the Parsons, Kansas pilot project.
- The Gravity Reactor uses standard pressurized water reactor technology installed one mile underground for passive safety features.
- DOE approval of the NSDA is the first step in the safety review process for the Reactor Pilot Program.
- The pilot reactor could transition to commercial operation if NRC licensing is secured post-testing.
The big picture
Deep Fission's public release of its NSDA reflects a strategic push for transparency in advanced nuclear development, aligning with broader industry efforts to build public trust. The underground deployment model challenges conventional reactor designs, potentially offering simplified safety and construction advantages. Success could position Deep Fission as a leader in next-generation nuclear power solutions for utilities and industrial customers.
