Over the past year, firms focused on small modular nuclear reactors (SMRs) have secured upwards of $1.5 billion in funding, driven by technology companies’ demand for energy to support AI model training and increasing governmental backing for the sector.
For instance, X-energy recently obtained $700 million in funding this month, and the Paris-based company Newcleo raised $151 million last year. Additionally, significant investments have flowed into U.S. projects like Oklo, NuScale, and Nano Nuclear, each receiving $700 million for similar initiatives.
Although nuclear fusion may still seem distant, SMRs are currently at the forefront of nuclear innovation. Thus, it is noteworthy that the SMR startup Valar Atomics has acquired $19 million in seed funding to initiate its first test reactor project. This round of funding was primarily backed by Riot Ventures, with participation from AlleyCorp, Initialized Capital, Day One Ventures, and Steel Atlas.
Valar’s SMR technology employs a helium-cooled, high-temperature gas reactor design. These reactors are intended to be constructed in what Valar refers to as ‘gigasites,’ serving as the nuclear counterpart to battery ‘gigafactories.’ By establishing a streamlined production process for SMRs, Valar aims to significantly lower the expenses typically associated with the unique and tailored construction of nuclear reactors.
Isaiah Taylor, Valar’s co-founder and CEO, told TechCrunch that the hurdles in reactor construction stem more from deployment issues than from technological limitations. He envisions that Valar’s ‘gigafactory’ model could address these challenges through a more “industrial” rather than “artisanal” approach.
The company is set to construct numerous SMRs mainly at off-grid locations to supply energy for data centers and industrial facilities. They have secured an initial agreement with the Philippines Nuclear Research Institute to build a reactor there. This contract includes plans for a pilot test-scale reactor and the construction of two full-scale reactors prior to the activation of the first integrated reactor.
“Our plan is to create the first, the second, and the third reactors, which will eventually evolve into a factory,” he stated.
Valar’s foundational technology can achieve temperatures of up to 900°C using helium gas—three times hotter than standard nuclear reactors. This capability enables Valar to efficiently create hydrogen and combine it with captured CO2, resulting in low-carbon synthetic fuels for various applications.
“If a nuclear reactor can reach such high temperatures, it can produce hydrogen at a low cost, unlocking numerous possibilities, including synthetic fuel production. We aim to make both the reactors and the hydrogen generation process economically viable,” Taylor explained.
“We designed, engineered, and built our thermal test unit within approximately ten months. This is certainly achievable; after all, the first-ever nuclear reactor was constructed in just eight months in 1943,” he added.
Taylor, whose grandfather coincidentally worked as a nuclear physicist on the Manhattan Project, left high school at the age of 16. He later pursued studies in software systems and founded multiple startups. The technical direction of the company is spearheaded by Chief Nuclear Officer Mark Mitchell, the former president of Ultra Safe Nuclear Corporation (USNC), who also led the first small modular reactor initiative at South Africa’s Pebble Bed Modular Reactor. Valar’s team includes several members from USNC, including Willem van Rooyen, its head of mechanical engineering.
While Valar’s aspirations are notably ambitious, the environment appears favorable for such nuclear ventures. The U.S. Inflation Reduction Act has catalyzed private investments in clean energy infrastructure, while China is also allocating $440 billion towards the establishment of new nuclear facilities. Furthermore, 14 of the leading global banks have shown their backing for the expansion of nuclear energy, aiming to triple its usage by the year 2050.
