Underground Nuclear Reactors? Inside Deep Fission’s Energy Solution

Liz Muller is the CEO and Co-founder of Deep Fission, a company pioneering a new approach to the traditional light-water nuclear reactor. Rather than using concrete and constructed containment, Deep Fission places the reactor one mile underground, fundamentally changing the design paradigm. Liz was on the show over five years ago when she was building a company focused on storing nuclear waste deep underground—a related concept. Now, she’s back with a fresh vision and a new venture. Deep Fission recently raised a pre-seed round led by Eight VC, and we wanted to catch up with her to hear how the idea came together and how she’s approaching the challenge this time around.
