| 7/31/25 | ![]() A State’s Recipe for Nuclear Success With Illinois Senator Sue Rezin | When it comes to moving the needle on nuclear energy, support is needed at every level, and Illinois is at a turning point. In this episode of Fissionary, Mary and Jordan sit down with Illinois State Senator Sue Rezin—a longtime advocate for nuclear energy—to talk about lifting the state’s partial moratorium and Illinois’ unique position to support nuclear energy production. With Illinois home to the largest nuclear fleet in the country and transmission infrastructure already in place, Sue makes the case for why the state is perfectly positioned to meet rising energy demands fueled by AI, data centers, and industrial growth. She shares how Illinois is developing its nuclear workforce earlier than most, why local buy-in is critical, and what she’s seen change the minds of nuclear skeptics. Beyond energy policy, Sue paints a picture of how leading in nuclear can fuel long-term economic growth and global competitiveness.
