- Apollo Atomics has obtained $31 million in seed funding, with FCVC main, to develop nuclear reactors that may be inbuilt factories.
- Its new steam generator design makes the reactor roughly 40 instances smaller.
- The corporate’s benefit would possibly stem from the regulatory experience of considered one of its co-founders, moderately than merely from technical innovation.
Apollo Atomics, a nuclear startup based in 2025 by Assil Halimi and Drew Walker, raised $31 million on the idea that coverage experience is simply as necessary as scientific potential with regards to acquiring reactor licences.
FCVC led the seed financing spherical for the Cambridge, Massachusetts-based firm, elevating $26 million in fairness and $5 million in debt.
Different buyers within the spherical had been Y Combinator, Telesoft Companions, Alumni Ventures, Robinhood Ventures, Nucleation Capital, Pelion VC, Duke Capital Companions, in addition to Paul Graham, Philip Johnston, Matteo Franceschetti, and Ray Rothrock.
Similar physics, smaller design
Apollo makes use of the usual pressurised-water design widespread to most nuclear energy vegetation, nevertheless it has redesigned the steam generator, usually the biggest and most complicated half.
The brand new steam generator has about ten instances the facility density, a characteristic which the corporate states makes the reactor about 40 instances smaller. This diminished measurement permits it to be inbuilt a manufacturing unit, transported to the positioning, and introduced into operation inside two years.
By securing provide chains for pressurised water reactors, the corporate can keep away from the technological dangers its opponents encounter when creating new reactor chemistries. The corporate intends to distinguish itself by dashing up manufacturing and regulatory approval, not by altering the reactor physics.
Apollo has constructed and run a reactor-system demonstrator at MIT’s Division of Nuclear Science and Engineering. The corporate states that the gasoline configuration of its business reactor has achieved full-power criticality. It has entered into letters of intent for greater than twenty gigawatts for its supposed merchandise, comprising the 10-megawatt A-10, the 50-megawatt A-50, and the 300-megawatt A-300.
A crowded discipline, the place paperwork issues as a lot as physics
This yr, funding for nuclear tasks has elevated, and Apollo is now getting into a extremely energetic sector.
Valar Atomics just lately completed a $1 billion Series B round, bringing its valuation to $6 billion. Antares has raised $470 million with the intention to meet a deadline set by the Pentagon.
Radiant Nuclear obtained $300 million simply at some point after Final Vitality closed its $100 million funding spherical. Blue Vitality additionally raised $380 million for a similar factory-built methodology, though its strategy entails financing total vegetation moderately than redesigning the reactor core.
Oklo, chaired by Sam Altman, has secured a 12-gigawatt provide settlement with Change however continues to be awaiting full design approval from the Nuclear Regulatory Fee. Kairos Energy has obtained the primary development allow from the NRC for a non-water-cooled reactor in additional than fifty years and in addition has a 500-megawatt cope with Google.
These firms don’t at the moment maintain a full business licence, and Apollo intends to handle this. Christopher Hanson, who was beforehand chairman of the NRC, serves on Apollo’s advisory board, and the corporate has submitted a plan aiming to acquire NRC approval of its gasoline design by the top of 2026.
Apollo is counting on Walker’s experience in logistics and manufacturing to speed up the regulatory course of, moderately than on reactor physics. Nevertheless, it’s not clear that this benefit will likely be adequate, because the NRC has delayed firms with extra sources and higher progress than Apollo.
What comes subsequent
The funds obtained will help Apollo in establishing its subsequent demonstrator, the one-megawatt A-1, and also will allow long-term reliability testing, the scaling of producing, and additional work with the NRC. Testing the brand new steam generator design ought to be easy.
The marketplace for small modular reactors is projected to increase from $6.54 billion in 2025 to $10.69 billion by 2033, representing an annual progress charge of 6.8%. Funding in nuclear power is being pushed by the rising demand for energy in information centres, which is outpacing {the electrical} grids’ potential to fulfill it.
The important thing concern is whether or not a former White Home operator can navigate regulatory obstacles extra successfully than the groups at Oklo and Kairos, who’re led by physicists.
