The best fuel for deploying #nuclear power at scale? The fuel that’s ready today. ⚛️
@DeepFission designed around the Low Enriched Uranium (LEU) fuel already supported by an established global supply chain and used in commercial reactors today.

Thank you for having me this morning, @BNNBloomberg.
This safety approval marks an exciting step forward on our journey to commercialization, and I’m excited of what’s ahead for @DeepFission.
Our CEO and co-founder Liz Muller joined @BNNBloomberg this morning to discuss our recently approved Nuclear Safety Design Agreement (NSDA) as part of the @ENERGY's Reactor Pilot Program.
This approval confirms that the foundational safety basis of our Gravity™ #Nuclear Reactor design warrants advancement to the next stage of development. She also provides a look at our technology and our pathway to commercialization.

Reaching this approval milestone with our full-power reactor design tells us something important: the fastest path to commercial #nuclear deployment runs exactly where we've been building it. ⚛️

JUST IN ➡️ @ENERGY has approved @DeepFission's Nuclear Safety Design Agreement (NSDA) for our Gravity™ Nuclear Reactor.
This marks an important regulatory milestone under the DOE's Reactor Pilot Program, confirming that the foundational safety basis of our reactor design warrants advancement to the next stage of development.
Our Parsons, Kansas, project is not designed as a one-time criticality demonstration. Our intent is for the demonstration reactor to transition to a fully Nuclear Regulatory Commission-licensed commercial operating unit, delivering electricity after initial testing and DOE authorization.
This reflects our commitment to building a direct, credible path from demonstration to commercial deployment.

I'm looking forward to joining the @CG_Driven Conference next week in Boston.
It's an exciting time for @DeepFission as we continue advancing our #nuclear commercialization efforts.
If you'll be attending, I'd love to connect. Looking forward to the conversations ahead.
Deep Fission $FISN CEO and Co-founder Liz Muller will present at @CG_Driven's 46th Annual Growth Conference in Boston on Tuesday, Aug. 11, at 1:30 p.m. ET, sharing our technology and commercialization approach.

Great to be back in Washington, DC this week with members of the @DeepFission team for several days of productive conversations about the future of #NuclearEnergy. ⚛️
We kicked things off with a valuable meeting @NRCgov to discuss commercialization and licensing.

It's our birthday! 🎉
Three years ago, we set out on a mission to power humanity from a mile underground. Today, that goal feels more tangible than ever.
Over the past year, we've reached several exciting milestones, including:
• Being selected for @ENERGY's Reactor Pilot Program
• Successfully drilling our data acquisition well to 6,000 feet deep
• Becoming a publicly traded company
• Delivering our prototype non-nuclear reactor canister to our site in Parsons, Kansas
Most importantly, we've continued advancing the engineering, testing, and validation that support our path toward commercial deployment, building on proven pressurized water reactor #nuclear technology.
Three years down, and we're just getting started.

The @DeepFission team has successfully fabricated and tested our first prototype reactor canister, achieving an important milestone on our path toward deployment.
The testing confirmed that the canister meets key industry requirements for structural integrity and leak tightness.
This canister will support testing of the integrated assembly, installation, and retrieval of a full-scale #nuclear reactor system within a borehole.
As we continue advancing these demonstrations, we're building the capabilities needed to validate our deployment approach to deliver reliable, affordable energy from one mile underground.

“These are all companies that they have different ideas, but they all have an intelligence, drive and a boldness about them…..My bet is 100% success.👏
Everyone that got chosen and is in this program… I can see it the eyes, and see it in the hearts…we are going to see success across the board.” -@SecretaryWright
We are honored to be among the 10 companies in the @ENERGY's Reactor Pilot Program, and feel energized from being personally recognized by Secretary Chris Wright today.
Our path to commercialization is feeling more important than ever.

Today marks an important milestone for @DeepFission as we begin trading on the @Nasdaq Global Market. ✨
This moment reflects the dedication of our employees, partners, supporters, and investors who have helped us on our path to advance the deployment of proven #nuclear technology in a new way.
We're excited for the opportunities ahead and focused on the work still to come.

Hello! I’m at #CleantechForumNA 2023 today and tomorrow. See me on a @TerrestrialMSR panel tomorrow talking about coal-to-nuclear repowering. & just come say “Hi!” if you see me

ENS HSC warned that if #Europe is not to be left behind in the #development of #nuclearpower systems for space it must find “sustained #commitment & substantial #investment over at least 20yrs”. Europe must develop its own nuclear resilient, and affordable long-term #capabilities

Reaching UK #netzero targets won't just be great for the #environment, but for health too - highlighted in this study shared by @CarbonBrief.
😷 Less air pollution
🥶 Well-insulated homes = better health
🚴 More physical activity & healthier diets

A 2023 goal: I want to share more of my personal journey. I’m a proud pro-nuclear environmentalist. There are many of us, but we aren’t always as vocal as we could be. Let’s speak up, together. 1/6 🧵
After I returned to Berkeley my dad and I co-founded the climate science nonprofit @BerkeleyEarth. I wanted to do something about global warming, and I learned more about nuclear energy, and why my friends opposed it. (Hint: It's about the waste.). 5/6 🧵
