Fuel for Thought

Today, we talk uranium nuclear fuel. MIT Professor Koroush Shirvan, joins me to dive into the hidden complexities of nuclear fuels. From early fuel experiments that saw uranium rods turn into spaghetti-like structures under neutron bombardment to the intricate economics shaping the future of fuels like TRISO, Shirvan offers insights into the realities behind nuclear power’s remarkable yet challenging fuel technologies.

Listen to discover how history shaped today's dominant fuel choices, why accident-tolerant innovations are critical, and about the economic realities that could either launch or limit the nuclear renaissance.
