Department of Energy Approves Nuclear Safety Design Agreement for Deep Fission's Gravity™ Reactor, Designed to Convert to Commercial Operation

BERKELEY, Calif.--(BUSINESS WIRE)--Aug 6, 2026--

Deep Fission, Inc. (Nasdaq: FISN) (“Deep Fission” or the “Company”), an advanced nuclear energy company developing small modular pressurized water reactors installed one mile underground, today announced that the U.S. Department of Energy (DOE), has approved the company's Nuclear Safety Design Agreement (NSDA) for its Gravity™ Nuclear Reactor. This marks a major regulatory milestone, confirming that Deep Fission's reactor design warrants advancement under the Department of Energy’s Reactor Pilot Program.

The NSDA approval establishes the safety framework that will guide the reactor's continued development. With this milestone in place, Deep Fission moves forward to the next phase of the DOE authorization pathway, advancing toward demonstration and eventual deployment of its underground nuclear reactor technology.

“This approval is a major step forward for Deep Fission,” said Liz Muller, co-founder and CEO of Deep Fission. “We believe our mile-deep design gives us the ability to move faster in the stages ahead.”

This regulatory progress comes as Deep Fission continues to advance its commercial pilot project at the Great Plains Industrial Park in Parsons, Kansas. Since breaking ground in December 2025, the company has drilled its first data acquisition well to 6,000 feet and recently delivered a prototype reactor canister to the site. Deep Fission is now progressing its proof-of-concept program, which includes large-diameter well drilling and prototype installation milestones, preceding full-scale demonstration at the site.

Deep Fission's Parsons project is not designed as a one-time criticality test. Consistent with the intent of Executive Order 14301 and the Reactor Pilot Program, the Company intends for its demonstration reactor to become a fully Nuclear Regulatory Commission-licensed, commercially operating unit, delivering power after initial testing and receiving DOE authorization. This reflects the Company's commitment to building a direct, credible path from demonstration to commercial deployment.

Deep Fission will continue working closely with the DOE as its design progresses through subsequent stages of review and authorization under the Reactor Pilot Program.

TORONTO--(BUSINESS WIRE)--Aug 6, 2026--

Borderless AI, the AI-native global employment platform, today announced the launch of Alberni, the AI-powered legal operating system for global employment. Alberni combines legal expertise with custom AI agents, allowing companies to hire and operate internationally without building a legal department in every country.

Managing a global team requires not only best-in-class payroll but also best-in-class employment law and compliance. Every new market brings different localized legal and workplace compliance requirements. Until now, companies have managed it all with a patchwork of local law firms, consultants, and spreadsheets, at a cost that scales with every hire and every border crossed.

Alberni was designed to eliminate the need for patchwork solutions. Borderless AI created Alberni as a single platform that pairs legal expertise with in-house AI, enabling companies to maintain a compliant global workforce footprint. This allows companies to handle everything from local entity formation and maintenance to worker classification, statutory deadlines, regulatory change, and workforce disputes. Deep legal expertise sets the foundation; AI makes it fast, consistent, and always on. This means companies no longer have to choose between moving quickly and staying compliant.

The launch comes as AI is rapidly transforming how law firms and in-house legal teams operate. Reports show a clear increase in the use of generative AI by firms and legal departments, with nearly half reporting use of AI in 2026 compared to just one quarter last year. There is a growing wave of new generation AI-native law firms, built without billable hours and staffed by lawyers working alongside AI.

However, legal AI is largely focused on law firms and litigators. Alberni brings the same legal expertise directly to companies. The companies for whom global compliance is a daily operational reality, not a matter for outside counsel. Global employment requires more than legal knowledge. It requires infrastructure, operational experience, and systems that scale. By combining Borderless AI’s global operations know-how with legal expertise, Alberni makes a company's global operations compliant by default in every jurisdiction in which it operates.

“Companies have always faced a barrier to hiring globally; every new market means more law firms, more retainers, and more risk,” says Willson Cross, CEO and Co-founder of Borderless AI. "We built Alberni so legal and regulatory compliance works like infrastructure: always on, always current, and smarter with every case. The companies that define the next decade will hire everywhere. We’re giving teams an easier and safer way to make that happen.”

With Alberni, companies get:

The launch of Alberni marks an additional step in Borderless AI’s mission to help companies onboard, pay, and manage talent in 170+ countries without hassle.
