Deep Fission Releases Nuclear Safety Design Agreement for Gravity Reactor

Deep Fission announced the public release of its Nuclear Safety Design Agreement for the Gravity Nuclear Reactor. The U.S. Department of Energy approved the NSDA as part of the Company's Reactor Pilot Program taking place in Parsons, Kansas. The NSDA establishes the safety framework that will guide continued development of the reactor. It reflects the agreement reached between DOE and Deep Fission on applicable design requirements, the planned safety analysis approach, and the regulatory engagement process that will govern the project. Public release of the document isn't required; Deep Fission is choosing to publish it to give the public direct visibility into the safety framework behind its approach as development evolves. DOE's approval of the NSDA is the initial step in the safety review process for the Reactor Pilot Program. Addition documentation and reviews are required before potential DOE authorization for operations. The Gravity Reactor uses standard, low-enriched uranium fuel and pressurized water reactor technology with a 70-year operating history. Rather than relying on a large above-ground containment structure, the design places the reactor approximately one mile underground, where a hydrostatic column of water and the surrounding geology are designed to provide passive pressure control, cooling, and shielding. The NSDA was developed and approved under the DOE Reactor Pilot Program, established by Executive Order 14301, which authorizes DOE to approve the design, construction, and initial testing of pilot advanced reactors outside DOE national laboratories, with the NRC observing the process. Unlike a standalone criticality test, the Parsons pilot is designed with the intent that the same reactor unit Deep Fission installs and brings to criticality under DOE authorization could, subject to NRC licensing, transition to commercial power operation rather than being decommissioned once initial testing concludes.

Deep Fission Successfully Installs Prototype Reactor Canister

Deep Fission announced that it has successfully installed and retrieved a full-size prototype reactor canister from a borehole using standard commercial drilling equipment operated by a commercial drilling and rigging crew. Nothing about the demonstration required equipment that had to be invented, custom-built, or adapted for nuclear service. "The most important thing about this demonstration is what we did not have to do," said Liz Muller, CEO and Co-Founder of Deep Fission. "We did not have to develop new technology. We used a rig and rigging that is commercially available in the field today, and our reactor uses pressurized water technology that has been operating in the nuclear industry for decades. Our innovation is in how we put proven pieces together, not in inventing something that has never been built. That is the difference between a science project and something you can deploy."
