Goal: Prevent the reactor from breaking and releasing radiation, similar to the Chernobyl disaster.
Chernobyl: The disaster was related to water used to cool the system and the inability to properly manage it, leading to a significant release of radiation.
Positives of Nuclear Energy
High energy output from a small amount of uranium.
Emission of only water vapor, avoiding pollution associated with burning carbon-based fuels.
Negatives of Nuclear Energy
Risk of meltdowns (e.g., Chernobyl).
Generation of long-lasting radioactive waste.
Potential use in weapons.
Nuclear Fusion
Fusion is the process of pushing two hydrogen nuclei together.
Fusion is what powers the sun, using immense density to fuse elements.
Releases more energy than fission.
Produces water as a byproduct, with no radioactivity.
Challenge: Requires extremely high temperatures (100 million degrees Celsius).
Research: Companies in Japan are working on structures to contain fusion.
Location: Happens in stars.
Temperature Considerations
Fusion requires extremely high temperatures (100 million degrees Celsius).
It is hotter than the sun.
Study Guide
