Study Notes
Nuclear Energy: The Good, the Bad, and the Ugly
- Nuclear energy is the largest source of clean power in the US
- Generates nearly 800 billion kilowatt-hours of electricity annually
- This is more than half of the nation's emission-free electricity
- Equivalent to removing 100 million cars from the road (reducing carbon emissions by 470 million metric tons annually)
Nuclear Fission
- Fission is the splitting of an unstable atomic nucleus (like uranium-235)
- This process releases a tremendous amount of energy
- A neutron is fired at a uranium-235 atom
- This causes the atom to split into smaller atoms (krypton-92 and barium-141) and release more neutrons
- These neutrons can then cause more atoms to split, creating a chain reaction
U.S. Nuclear Power Plants
- A map shows the locations of active, decommissioned, and potential future nuclear power plants in the U.S.
The Good
- Nuclear power is a relatively cheap way to generate large amounts of energy from uranium
- Price fluctuations of Uranium are limited
- Technological advancements make it more efficient
- The energy released is ten million times greater than when burning fossil fuels
- One power plant produces thousands of megawatt hours of energy
- Very little fuel is needed
- Plants operate non-stop once working
Nuclear Fusion
- Nuclear fusion combines light atomic nuclei to form heavier ones, releasing massive amounts of energy
- Considered the holy grail of energy harnessing technology
The Bad
- Nuclear power plants require substantial amounts of water for cooling
- US consumed billions of gallons of water for nuclear power production in 2015
- This water usage is higher than coal processing
- Climate change is a concern regarding water usage
Non-Renewables
- Uranium is a non-renewable resource
- Experts estimate 200 years' worth of uranium is available at the current rate of mining
- Switching to nuclear energy as a primary alternative would deplete uranium faster
The Ugly
- Nuclear meltdowns are accidents caused by severe heating and lack of sufficient cooling at the reactor core
- These meltdowns occur in different stages, releasing potentially high radiation
- There has been only one almost complete nuclear meltdown in the history of nuclear energy: Chernobyl
Other Nuclear Incidents
- Windscale Fire
- Three Mile Island
- Tokaimura
- SL1 Island
- Fukushima
- Research these incidents for causes, affected populations, and similarities/differences
Technology to Fight against Meltdowns
- More frequent maintenance
- Backup backup generators
- More monitoring on seismic activity
- Coast plants built with anti-flooding/anti-electric loss systems
- Move more plants inland
- Switching coolants
Overall
- Don't panic
- This is not an exhaustive list. Research individually assigned topics.
