Nuclear Fission
Definition: The splitting of a large atomic nucleus (e.g., uranium) into smaller nuclei with the release of energy.
Parts of a Fission Reactor
Functionality and components involved in nuclear fission processes.
Advantages of Nuclear Power
Environmental Impact: Does not release greenhouse gases, such as carbon dioxide.
Energy Efficiency: Releases one million times more energy per kg compared to chemical reactions (e.g., burning coal, oil, gas).
Fuel Requirements: Requires significantly less fuel than conventional power stations, reducing transportation and mining costs.
Employment Opportunities: Generates jobs in various sectors.
Safety: Modern reactor designs are extremely safe.
Disadvantages of Nuclear Power
Public Concerns: Fear of living near nuclear plants and radioactive waste storage facilities due to potential leaks.
Historical Incidents: Accidents in Ukraine and Japan have caused extensive economic, health, and environmental damage.
Greenhouse Gases: Mining, transport, and purification of uranium ore contribute to greenhouse gas emissions.
Non-renewable Resource: Uranium, like fossil fuels, is a non-renewable energy source with limited supply.
Radioactive Waste: Highly dangerous, long-lasting waste requires expensive, secure storage solutions.
Leakage Risks: Concerns about potential leaks causing soil and water pollution, especially in earthquake-prone regions.
Decommissioning Costs: High costs and skilled labor required to safely decommission nuclear power facilities.
