Episode notes
Derek's Research Reactor Tour
- Derek Gaston shares his experience touring a research reactor at University of Texas.
- He describes the unique and impressive blue glow called Cherenkov radiation visible during reactor pulses.
How Nuclear Power Works
- Nuclear power plants generate heat to produce steam which spins turbines and generates electricity.
- In nuclear reactors, chain reactions of uranium atoms releasing neutrons create the heat for this process.
Reactor Types in U.S.
- Two main reactor types in the US are pressurized water reactors and boiling water reactors.
- Pressurized water reactors keep water hot under pressure; boiling water reactors boil water directly to produce steam.
