Small modular reactors: concept and status

Nuclear engineer & former Miss America, Grace Vanderhei joins Chuck Todd to break down the realities of nuclear energy—what’s safer than most people think, what genuinely needs fixing, and why public perception has lagged so far behind the science. From how she got into nuclear engineering to how disasters like Fukushima reshaped the industry’s momentum, Grace explains why rare accidents dominate the narrative, even as nuclear power remains one of the safest jobs in the country. The conversation explores America’s aging nuclear infrastructure, the challenges of upgrading decades-old plants, and why rising grid demand from AI is pushing utilities to restart and refurbish reactors instead of building new ones. Chuck and Grace also dig into the promise and limits of small modular reactors, the unresolved problem of nuclear waste storage, and how pop culture—from Homer Simpson to Hollywood—has warped the way we think about nuclear energy, all while pointing listeners to where they can follow Grace’s work and research.
