Doug Bernauer is the CEO and Co-founder of Radiant. Radiant is developing a portable nuclear micro-reactor to replace diesel generators. They raised a $40 million Series B in 2023 led by a16z, after previously raising capital from investors including USV, Founders Fund, and DCVC. They're targeting the development of a portable, mostly self-contained, one-megawatt nuclear reactor that is roughly the size of a shipping container.

We've been focusing more on nuclear energy lately, exploring whether the US could reclaim its position as a global leader. With bipartisan support reflected in recent legislation like the ADVANCE Act signed into law by President Biden, there are signs of progress, but significant challenges remain.

In this episode, Doug discusses these challenges and delves into Radiant’s technology, use cases, fuel, and more.
