3. Disadvantages of Nuclear Power Nuclear accidents, though rare, can have catastrophic consequences, as demonstrated by events like Chernobyl and Fukushima, leading to extensive environmental and health impacts. High Initial Costs Risk of Accidents Radioactive Waste The construction of nuclear power plants involves substantial upfront investment and lengthy development timelines, which can deter investors. The disposal of nuclear waste poses significant challenges as it remains hazardous for thousands of years, requiring secure and long-term storage solutions. 3 2 1

4. Long-term Fuel Supply Uranium, the primary fuel for nuclear reactors, is abundant and can be sourced sustainably through mining and recycling processes. Potential for Innovation Advances in nuclear technology, such as thorium reactors and fusion energy, promise even more sustainable and safer energy production methods in the future. Sustainability of Nuclear Power Complement to Renewables Nuclear power can act as a reliable backup to intermittent renewable energy sources, helping to stabilize the energy grid and support the transition to a low-carbon future.

5. Stringent Regulations Nuclear power plants are subject to strict safety regulations and oversight to minimize risks and ensure the protection of workers and the public. Emergency Preparedness Modern reactor designs incorporate advanced safety features, such as passive safety systems that automatically shut down in emergencies, enhancing overall safety. Technological Improvements Comprehensive emergency response plans are in place to address potential accidents, including evacuation protocols and radiation monitoring. Safety of Nuclear Power

6. The released neutrons can initiate further fission reactions, creating a self-sustaining chain reaction that produces continuous energy output. Nuclear fission is the process where the nucleus of an atom splits into smaller parts, releasing a tremendous amount of energy, primarily used in nuclear reactors. Understanding Fission Reaction Fission Process When a heavy nucleus, such as uranium-235, absorbs a neutron, it becomes unstable and splits, releasing additional neutrons and energy.
