  • Great show

    Love this pod, very interesting. One presenter, John, talks in too halting a manner, but the show is always intelligent & stimulating.

  • Content far better than audio

    Excellent content, but the audio in the April 28, 2002 episode with Chris keefer was terrible. Keefer’s sounded like an intercom and the host’s like he was at the bottom of mineshaft. Still, I’ve learned a ton from this show.

Talking Points

Recent interactions between the hosts and their guests.

Powering the Moonbase ft. Tyler Bernstein (Zeno Power)
Q: How do government partnerships influence private investment and timelines for your roadmap?
DOE and NRC are increasingly collaborative partners, helping to secure fuel supply, streamline licensing, and de-risk the supply chain. This bipartisan support reduces regulatory delays, encouraging private capital to commit at scale and accelerates the path to large deployments in space and on the seabed.
Powering the Moonbase ft. Tyler Bernstein (Zeno Power)
Q: What can you tell us about the Vallecitos hot-cell facility and how it will impact your production timeline?
Vallecitos provides full-scale production infrastructure with large, shielded hot cells that allow automated processing, encapsulation, and assembly of heat sources into nuclear batteries. This facility accelerates scale from R&D to mass production, enabling delivery to Moonbase and maritime customers as early as 2027 and scale in 2028.
Powering the Moonbase ft. Tyler Bernstein (Zeno Power)
Q: Can you give us a rundown of what Zeno Power does and how your technology differs from traditional fission-based systems?
Zeno builds nuclear batteries using radioisotopes like strontium-90 and tantalizingly, isotopes such as americium-241 for space applications. The key is long-lived heat that is converted into electricity in compact, transportable power sources, enabling persistent energy in deep sea, space, and remote environments without relying on traditional fission or solar in challenging conditions.
Perpetuating the Nuclear Lifecycle Ft. Ken Rueter (UCOR)
Q: What does UCOR actually do on a day-to-day basis in Oak Ridge?
UCOR conducts decommissioning, characterization, decontamination, demolition, and remediation of former Manhattan Project and Cold War facilities, employing a mix of remote robotic systems and human teams, with a focus on reducing environmental liability and enabling land reuse.
Perpetuating the Nuclear Lifecycle Ft. Ken Rueter (UCOR)
Q: Tell me how you ended up as president and CEO of UCOR.
Ken Rueter describes a long-form career starting as a laborer and moving through chemical engineering and environmental remediation, culminating in leading UCOR after a series of mergers and acquisitions, with the Oak Ridge cleanup contract and brownfield redevelopment at the center of his trajectory.
