episode 359: Modern Fission Reactors


Guest: Jacopo Buongiorno   Host: Markus Voelter   Shownoter: Andy Joiner

In this episode we take a look at newer generations of fission reactors, those that are currently being developed or researched. Our guest is Jacopo Buongiorno of MIT. We discuss some of the high-level goals of these new reactors, such as increased safety and efficiency, and then look at a few of the interesting new designs and how they realize these goals. We also briefly cover some of the policy arguments around keeping fission in the mix for combatting climate change.
