The Nuclear Company, a startup founded in 2023, has raised US$51.3 million in a series A funding round, bringing its total funding to US$70 million.

Eclipse led the round with participation from CIV, Goldcrest Capital, MCJ Collective, True Ventures, and Wonder Ventures.

The company plans to develop a fleet of nuclear reactors based on existing designs, focusing on sites that already have permits or licenses.

Each site is expected to support reactors with over 1 gigawatt capacity, targeting a total of 6 gigawatts in the initial fleet.

The Nuclear Company’s reactors are not expected to be operational until the early 2030s.

🧠 Food for thought

1️⃣ Nuclear’s historical funding challenges mirror today’s investment patterns

The Nuclear Company’s $51.3 million raise illustrates how nuclear startups continue to attract significant venture capital despite the sector’s complex funding history.

Nuclear R&D funding has experienced a dramatic shift over five decades, declining from 73% of total energy R&D in 1975 to just 20% by 2015, while renewables gained ground 1.

This funding evolution explains why the company is pursuing an approach that leverages existing designs and pre-permitted sites rather than developing entirely new reactor technology, a strategy that addresses the historical challenge of demonstration projects falling short despite billions in investment.

Despite over $1.3 billion in Department of Energy funding for nuclear reactor R&D in 2021, the industry has seen few successful demonstrations of new nuclear generation technologies over the past two decades 2.

The Nuclear Company’s focus on permitted sites is particularly strategic given that nuclear projects face extraordinary financing hurdles due to their high capital costs, which typically account for over 60% of a nuclear plant’s total costs 3.

2️⃣ Energy demand surge creating unprecedented renewable-nuclear coexistence

The projected 16% increase in U.S. electricity demand by 2029 is creating a unique market dynamic where both nuclear and renewables can expand simultaneously rather than competing for market share.

Data centers represent the primary driver of this demand growth, with their electricity consumption expected to quadruple by decade’s end, creating space for multiple generation technologies.
