Nucleation's Fund I Portfolio

Aalo Atomics  – Leveraging their experience designing the DOE’s Gen IV microreactor, MARVEL, an advanced nuclear reactor developed at the INL, to expedite the design, review, approval and scaled deployment of a fleet of highly stable and safe commercial sodium-cooled microreactors optimized for use by data centers and others.

Blue Energy – An innovative, early-stage, Massachusetts-based nuclear plant designer and integrator, working to develop a novel, off-shore methodology to deploy licensed small modular light water reactors (SMRs) at scale using monopiles and other mature, off-the-shelf wind turbine deployment techniques. 

Blykalla (formerly LeadCold) – The Swedish developer of the high-temperature, low-cost, lead-cooled reactor called the Swedish Advanced Lead Reactor (SEALER) and currently the only Swedish advanced nuclear developer in a country looking to add more nuclear power.

Copenhagen Atomics – A Danish developer of a thorium molten salt thermal breeder reactor—which turns nuclear waste into fuel—is looking to mass manufacture thorium-powered reactors at an exceptionally low price.

Core Power – the United Kingdom-based partner in the Molten Chloride Fast Reactor (MCFR) development consortium, together with TerraPower, Southern Co. and Orano, with exclusive rights to market and license this reactor into the marine market.

Deep Isolation – A Berkeley, California and Austin, Texas-based developer of deep geologic borehole technology for the temporary or permanent storage of nuclear waste, in boreholes drilled in closer proximity to nuclear power plants.

Focused Energy – A Redwood City, California-based developer of a laser Inertial Fusion Energy (IFE) approach to fusion energy production, leap-frogging from the related progress achieved at the National Ignition Facility, with improved fuel capsules and more powerful lasers.

NuclearN – A Phoenix, Arizona-based developer of nuclear AI support modules and services, which are already in use by a majority of North American nuclear power plant operators, working to enable maximum efficiency and efficacy of operational budgets.

Path Power – An innovative, early-stage California-based developer of a robotic and AI-enabled system for drilling and laying transmissions lines underground, without the need for trenching. 

Planetary Technologies – A Canadian-based developer of an Ocean Alkaline Enhancement (OAE) approach to marine carbon dioxide removal (mCDR) which leverages the water cooling systems of existing nuclear power plants or waste treatment plant effluents to effect distribution of their "antacide" and maximize decarbonization of seawater and climate restoration.

Radiant Nuclear – An El Segundo, California-based developer of Kaleidos, a mobile high-temperature gas nuclear microreactor that replaces diesel generators.

SHINE Technologies – A Wisconsin-based developer of fusion energy, commercializing in the interim their high flux neutrons from DT fusion for radiation effects testing, isotope production and waste separation enroute to development of cost-effective fusion energy, producing Ilumira, a potent cancer therapy, made from Lutetium-177.

Syntholene  – A former UK, now US-based integrater of low-carbon energy for synthetic fuel production, for drop-in substitution for diesel, gasoline and kerosene.

Twelve (Q1-24) – A  Berkeley, California-based developer and producer of sustainable aviation fuel (SAF) and naphtha using a “power-to-liquid” approach to reducing carbon by 90%.

Ultra Safe Nuclear Corporation – A Seattle, Washington-based developer of the Micro Modular Reactor, a TRISO-fueled, high-temperature gas reactor, designed to be built underground for maximum safety, as well as micro-space reactor.

Zeno Power – A venture harnessing the radioisotope decay from nuclear waste such as Strontium-90 to generate electron flow for years of reliable energy for frontier applications from deep sea to deep space.
