Study Notes

Nuclear Power Basics

Nuclear power is a climate-friendly energy source, generating power without releasing carbon dioxide, a greenhouse gas.
Nuclear power plants work on the concept of nuclear fission, where uranium nuclei are bombarded with neutrons, releasing heat, radiation, and more neutrons.

Safety Concerns

Nuclear power plants can accidentally release radiation into the environment or be targeted for a terrorist attack.
In a nuclear reactor, the uranium chain reaction is controlled, preventing an explosion like an atomic bomb.
A meltdown can occur if the cooling system fails, resulting in the melting of the reactor's core and potential radiation release.

Health Concerns

Exposure to radiation can have negative effects on the human body, potentially causing cancer or radiation sickness.
Radiation sickness symptoms include skin burns, nausea, vomiting, diarrhea, hair loss, general weakness, and possibly death.

Environmental Concerns

Nuclear power plants use local water sources for cooling, which can disrupt aquatic life and release pollutants into the waterway.

Terrorism and Security Concerns

Containment walls surrounding nuclear reactors are designed to withstand hurricanes, tornadoes, earthquakes, and small plane crashes.
Terrorist attacks on nuclear reactors are a concern, but the impact of such an attack is unpredictable.

Radioactive Waste Disposal

Radioactive waste from nuclear fission cannot be disposed of by conventional means due to its long-lasting radioactivity.
Current storage methods involve cooling and storing spent fuel rods on-site, with long-term storage facilities being researched.
Potential repository sites like Yucca Mountain Nuclear Waste Repository are being evaluated for permanent storage of nuclear waste.
