Assembling tens of modular nuclear reactors per year is technically manageable in-house, but scaling to hundreds stresses external component suppliers. The principal manufacturing obstacle is convincing specialized vendors supplying pumps, sensors, and structural steel to co-invest capital and expand production at identical paces.

Radically departing from the traditional model of massive, on-site construction, Radiant is designing portable micro-reactors to be mass-produced in a factory. This "reactor as a product" approach aims to deliver power solutions that can be shipped and activated in 48 hours.

The primary flaw in nuclear energy economics is that every plant is a unique, bespoke construction project, leading to massive cost overruns. The solution is to treat nuclear power plants as standardized, factory-produced products, much like cars, to achieve predictability, speed, and cost reduction through scale.

The 40-year plateau in nuclear power wasn't driven by public fear after incidents like Chernobyl, but by the soaring costs of building massive, one-off reactors. The modern push for Small Modular Reactors (SMRs) aims to solve this fundamental economic problem through factory-based production.

While current nuclear projects take 10-15 years in the US, the country used to build reactors in just three years. The goal is not just creating new technology, but streamlining paperwork and supply chains to restore past efficiency. The bottleneck is bureaucracy, not technical capability.

The transformative potential for nuclear energy isn't merely building components in a factory. The real breakthrough is achieving assembly-line mass production, using robotics and standardization to reach a pace and cost structure similar to the automotive industry—a significant leap beyond current "factory-built" concepts.

Nuclear-grade components can be 3-10 times more expensive than their commercial equivalents. This massive markup isn't due to exotic materials but is almost entirely driven by the immense "compliance overhead" and documentation required, creating a major opportunity for software-driven cost reduction.

Most reactors marketed as SMRs are neither small enough for standard road transport nor truly modular. Their components, sourced from dozens of different factories, often fail to integrate on-site, leading to the same delays and cost overruns as large-scale projects. True modularity requires single-factory production.

To achieve a mass-production model akin to Henry Ford's, nuclear reactors and plant modules must conform to the existing global transportation network. The ideal size is not the largest possible for economy of scale, but one that fits on standard roads and ships, enabling rapid, parallel deployment of thousands of units.

A key innovation for modular nuclear power is the turbine technology. Supercritical CO2 turbines are much smaller and more efficient (up to 50%) than traditional steam turbines. This size reduction is crucial because it makes them suitable for mass manufacturing, aligning with the strategy of factory-building the entire power generation system.

Decades of chasing economies of scale through custom, progressively larger gigawatt-scale plants led to budget blowouts and unpredictability like the Vogtle project. Building the exact same smaller reactor hundreds of times creates manufacturing learning curves that reduce costs much faster than one-off plant construction.
