The Future Belongs to Builders ft. Jonathan Webb (The Nuclear Company)
In the final installment of my follow up series with nuclear companies, I spoke with Jonathan Webb, the co-founder and CEO of The Nuclear Company.
For those who don’t know, TNC is pursuing a fleet-scale build of big reactors (and perhaps small ones too!) with cutting edge tech to turn blue collar workers into the Iron Men of megaprojects. Jonathan broke down his vision for nuclear, why workers are the key to everything, what’s going on with TNC’s VC Summer build, and so much more. His big-hearted passion for nuclear really struck a chord with me.
Check out last year’s episode with TNC’s Chief Nuclear Officer, Joe Klecha, here.
And, if you’re in DC, check out TNC’s operating system demo at Deep Tech Week on September 8th!

Can I Be Fusionpilled? ft. Andrew Holland (Fusion Industry Association)
I'll admit, I'm a bit of a fusion skeptic. But! There are exciting things happening in the fusion industry these days. So, I brought Andrew Holland, CEO of the Fusion Industry Association, to talk to me about why things are looking up for fission's avant-garde cousin. Andrew's candor, insight, and enthusiasm made him a great guest. I had questions about everything from break-even hurdles to robotics and he handled it all with aplomb. I came away from this episode convinced that regardless of how near or far away commercial fusion may be, America should invest in R&D to try and crack it: the tech is too cool and the lessons we'll learn along the way too valuable.

Waste Not, Want Not ft. Carl Perez (Exodys)
In today’s episode, I got to talk about something near and dear to my heart (nuclear waste reprocessing) with Carl Perez of Exodys Energy, a nuclear waste reprocessing company. Carl is a wealth of knowledge, as you’ll hear in the episode. We discuss the basics of waste reprocessing, the history of the industry, what makes Exodys stand out, and why getting waste reprocessing right will change the world.

Texatomica ft. Reed Clay (Texas Nuclear Alliance)
Reed Clay, President of the Texas Nuclear Alliance, joined me today to talk about how Texas is gearing up for the nuclear renaissance. We discussed how he came to support nuclear by learning about waste, what has set Texas’s nuclear strategy apart from other states, how TNA’s annual summit is shaping the national nuclear landscape, and Reed’s advice for other states that want to become nuclear hubs.Reed is a humble, hard-working guy and it was a pleasure to speak with him.
