Nucleation Capital is pleased to congratulate Radiant Nuclear and share their December 17th announcement of its close of a $300+ Million Series D financing, led by Draper Associates and Boost VC for a combined $100 million check. Many prior Radiant investors are also re-investing including DCVC, Andreessen Horowitz, Founders Fund, Nucleation Capital and others.
Nucleation Capital is participating in this Series D financing, so all current subscribers will gain access to this investment, which marks Nucleation's third investment into Radiant since the company raised its Series A in 2021. Additionally, this will be the first time that Nucleation has invested three times into a venture, which is a reflection of the company's impressive success knocking down milestones towards the design, development, construction, testing and licensing of Kaleidos, the company's 1 MW transportable power generator.
Radiant is among a small handful of advanced nuclear developers that are making rapid strides towards initial builds and testing of novel reactor designs through a combined DOE/NRC licensing approach. As one of just three companies selected for DOME testing of its reactor in the DOE FEED Program back in 2023, Radiant managed to win the #1 testing slot, beating Westinghouse's eVinci for the right to commence testing in 2026, securing what we think could be an early-mover advantage in the race towards full commercial NRC licensing.
This new capital raise, which came together quickly less than a year after the company's Series C, will support the company's DOME testing and scaling of its commercialization efforts, particularly the design and build-out of Radiant's production factory, R-50, being sited in Oak Ridge, Tennessee on an 85-acre parcel of former Manhattan Project land.
Nucleation Capital, whose Fund I is a long-term investor in Radiant, builds boutique portfolios of top ventures innovating within the advanced nuclear and nuclear-adjacent sectors. There is so much demand across every sector for better sources of clean, reliable energy, we believe that there is a huge opportunity for those ventures like Radiant delivering reliable clean power systems that meet the energy needs in specific niches like data centers, remote villages, industrial centers, universities, hospital campuses, marine transport fleets, forward military bases, vehicle charging stations, large towns and urban district heating systems.
Fund I is designed primarily to provide curated and affordablce access for accredited and other high networth investors. Nucleation's Fund II is designed to provide institutional LPs with boutique access to these rarified clean energy sectors, though skewed slightly later stage.
Nucleation's Fund I operates on a quarterly subscription model and accepts new investors (as limited partners or "LPs") on a rolling basis. Investors select the level and term that works for them—from as low as $10,000 to as high as $1 milion per year—and fund on a quarterly basis to receive a pro rata allocation in each of the investments Nucleation makes each quarter.
