Nucleating the carbon-managed economy, where our abundant clean energy, anchored by a diverse menu of types of 24/7 nuclear energy suitable for every need, begins to draw down excess CO2 and restore the energy balance of our climate.
Even better, if you subscribe to Nucleation Fund I this quarter, you'll get a your pro rata in all 3 of our Q3 investments & a special bonus, which just may be the incredible @Isodope nuclear survival kit, with a copy of Rad Future. What could be better? venture.angellist.com/v/l/V2OOO
5. On the fuel supply side: @RadiantNuclear signed an advanced fuels deal with Urenco to get HALEU (high-assay low-enriched uranium), and TerraPower + KBR are studying sites in the U.K. for their Natrium reactor + energy storage system.
4. @LastEnergy is exploring deployment of microreactor PWR-20 units at London Gateway port (in collaboration with DP World), coinciding with £1B expansion there.
3. @holtecintl & EDF UK (and partner Tritax) plan to deploy SMR-300 reactors at the former Cottam coal power station to power new data centers, using existing infrastructure.
2. @xenergynuclear and Centrica are partnering to deploy up to 75 Xe-100 small modular reactors (SMRs) across the U.K., with an estimated economic value around $54 billion. The first deployment is planned beside the Hartlepool site.
1. A new UK-government press release states the pact aims to speed up construction of nuclear projects by shortening licensing timelines (from ~3-4 years down to ~2 years).
The U.S. and U.K. are escalating nuclear cooperation with multiple new deals, especially timed around President Trump’s upcoming state visit. Here is a summary of key points 🧵 around these collaborations.
This shows how quickly the narrative is changing—local communities— even in America’s farm belt, are starting to value the nuclear they have as the lowest-cost path to energy security and climate resilience. 🌽⚛️
Not a done deal but a step in the right direction, for sure!
🚨 Big news out of Iowa: State regulators just approved a new nuclear zoning district that could pave the way for restarting the Duane Arnold nuclear plant, shuttered in 2020.

By 2030, NASA & industry partners could land a nuclear reactor on the moon. Space exploration powered by the atom—it’s closer than we think. www.npr.org/2025/08/08/...🌙⚛️

She's figured out how forests make rain and wind and regulate climate. Many more variables and much more complex than nuclear reactor physics. Definitely worth reading her amazing substack: bioticregulation.substack.com
Next up, in our Women in Nuclear profiles, atmospheric physicist, Anatassia Makarieva, working in the Theoretical Physics Division of Petersburg Nuclear Physics Institute. nucleationcapital.com/anastassia-m...
Recommend reading Dr. Anatassia Makarieva's Biotic Pump substack to get a really good understanding of why the atmospheric physics of those hurricanes is so fierce: bioticregulation.substack.com
The gulf has now reached the hottest it has ever been, in recorded history at least. This is a measure of OHC or ocean heat content.
Remember, we are smack dab in the middle of hurricane season. A hurricane that enters these waters will intensify rapidly due to all the energy.
Nuclear operates pretty much 24/7 generating clean energy—with improving Capacity Factors. 🌍⚡ The only problem is, many people have no idea if that's fission or fusion! Startling number think it's #fusion.

#NuclearNow #CleanEnergyFuture #ClimateAction
☀️ It’s a big change to see @ENERGY putting out beautifully-done graphics, such as this one on Energy #CapacityFactors. We're finally seeing promotion of #NuclearPower!
And yes, nuclear doesn’t depend on weather, pollute or cause #climatechange.
Big news for #clean, reliable energy in the U.S. @TVANews & @ENTRAone are planning 6 GW of new nuclear—enough to power millions of homes—with an expected budget > $40B. A huge step forward! ⚛️🏡

Fossil fuel supporters want people worries about #nuclearwaste to prevent nuclear energy from growing and as a distraction from the serious lethality of fossil fuel waste that kills millions every year and is actively causing our climate crisis.
#NuclearInnovation #WasteToFuel
And @CurioLV announced the completion of a laboratory-scale demonstration of its NuCycle voloxidation processing technology. If we reprocessed all existing nuclear waste, it could power the US for a century.
Rather than store or dispose it, there are ways to reuse and get enormous value from this resource. Oklo is planning to reprocess its used fuel at a new nuclear waste center in Tennessee; @SHINEfusion will separate out valuable isotopes and U using neutron flux capabilities.
If you are concerned about #nuclearenergy because of its waste, you should know that nuclear's waste is really one of its best features! Unlike #fossilfuel waste—which is allowed to pollute the air, cause disease and #climatechange—nuclear's miniscule waste is fully contained.
There is a race to build the future of energy . . . there just not the hot "contest" that some think there is between fission and fusion. One type has worked beautifully for almost 70 years: the other has never worked.

It's fascinating that many investors are willing place a bet on fusion—despite the fact that fusion has yet to put a single electron on the grid—and yet they find fission innovation's prospects unenticing, though it's been commercial for almost 70 years—and now getting a 40-year belated upgrade.
