Nuclear fission is the process of splitting atomic nuclei, typically uranium-235 or plutonium-239, to release energy. This energy heats water to produce steam, which drives turbines to generate electricity. Fission is widely used in nuclear power plants due to its high energy output and low greenhouse gas emissions. However, challenges include radioactive waste disposal, nuclear proliferation risks, and reactor safety concerns. Advances in reactor designs, such as small modular reactors (SMRs) and Generation IV reactors, aim to improve efficiency and safety while reducing waste. Nuclear fission remains a major component of global electricity generation.
- Energy security – Reduces dependence on fossil fuel imports and supports stable national power grids.
- Regulatory frameworks – Highly regulated sector, with licensing and oversight by nuclear safety authorities.
- Public policy divide – Some governments invest heavily in fission, others phase it out due to safety and waste concerns.
- Geopolitical implications – Uranium supply, enrichment capabilities, and proliferation risks influence foreign policy.
- High capital costs – Reactor construction is expensive and often experiences budget overruns.
- Low operating fuel costs – Uranium is relatively inexpensive and energy-dense.
- Long plant lifespans – Typically 40–60 years, offering long-term returns if managed well.
- Decommissioning expenses – Safe dismantling and waste disposal can cost billions over decades.
- Public perception – Mixed, with strong opposition in some countries due to past accidents.
- Job creation – High-skilled employment in engineering, operations, and maintenance.
- Energy reliability – Provides consistent, large-scale power to support industrial and residential demand.
- Community trust – Requires ongoing transparency and communication to maintain acceptance.
- Reactor designs – Includes pressurised water reactors (PWRs), boiling water reactors (BWRs), and advanced designs like small modular reactors (SMRs).
- Safety systems – Multiple redundant layers to prevent accidents and contain radiation.
- Fuel cycle technology – Uranium enrichment, fuel fabrication, and spent fuel management.
- Innovation trends – Advanced reactors aim to improve safety, efficiency, and waste reduction.
- Strict regulation – Licensing, operational compliance, and security requirements are enforced by national authorities.
- Waste management laws – Govern long-term storage and disposal of spent nuclear fuel.
- Non-proliferation treaties – International agreements to prevent diversion of nuclear materials for weapons.
- Liability laws – Define responsibility and compensation in the event of accidents.
- Low operational emissions – Virtually no CO₂ emissions during power generation.
- Radioactive waste – Long-lived isotopes require secure containment for thousands of years.
- Accident risk – Rare but potentially catastrophic events can have lasting environmental impacts.
- Land and water use – Plants require cooling water sources and have moderate land footprints.
