Company mission

To bring one of the world's first factory-constructed microreactors to market.

Our take

To support the clean energy revolution, Radiant Nuclear is developing a portable, containerised nuclear microreactor. Once launched, it will have the potential to provide power to remote parts of the world or act as a backup supply to vital infrastructure such as hospitals and data centres.

Typically, these backup systems are powered by diesel generators - making them extremely bad for the environment. Radiant's microreactors could allow the replacement of these generators whilst supplying the same critical asset support, enabling a substantial reduction in carbon footprint.

Having completed the design phase of the project, Radiant has taken a step closer towards realising its portable microreactor (known as Kaleidos). On the back of impressive Series D funding, the company intends to test a prototype as early as mid-2026 and has secured considerable funding to support its work towards that goal.
