Context:
Recent military strikes by the U.S. and Israel on Iranian nuclear facilities, along with continued threats to Ukraine’s Zaporizhzhia nuclear power plant, highlight a dangerous erosion of international norms protecting nuclear infrastructure. Such attacks increase the risk of radiological disasters, nuclear proliferation, and global environmental contamination.
Key Highlights:
Escalation of Attacks on Nuclear Facilities
- Since 2024, the United States and Israel have reportedly carried out strikes targeting Iranian nuclear facilities.
• Key sites affected include Fordow, Natanz, and Isfahan nuclear facilities.
• March 2026 strikes reportedly damaged Natanz installations and Bushehr airport infrastructure.
Global Precedents of Nuclear Infrastructure Threats
- The issue follows Russia’s capture of Ukraine’s Zaporizhzhia Nuclear Power Plant in 2022 during the Russia–Ukraine war.
• The plant has faced repeated shelling and military activity, raising concerns about nuclear safety.
• These incidents indicate a growing global pattern of targeting or endangering nuclear infrastructure during conflicts.
Environmental and Radiological Risks
- Experts warn that attacks on reactor cores or spent fuel storage pools could release radioactive isotopes such as Caesium-137.
• Potential consequences include:
- Acute radiation sickness
- Long-term land contamination
- Agricultural damage and food insecurity
- Cross-border environmental impacts
Questionable Strategic Effectiveness
- Claims that Iranian facilities were “obliterated” are disputed.
• The International Atomic Energy Agency (IAEA) reports that enriched uranium stockpiles remain largely intact.
• Military strikes may instead push nuclear programs underground into more secretive facilities, making monitoring harder.
Legal and Diplomatic Concerns
- Geneva Conventions (Protocol I) prohibit attacks on installations containing dangerous forces, including nuclear power plants.
• Attacks on such facilities may represent violations of international humanitarian law.
Geopolitical and Security Implications
- Iran has strengthened strategic cooperation with Russia and China, including:
- Advanced air defense systems
- Navigation and military technology support.
- There are fears of asymmetric retaliation, including:
- Attacks on U.S. military bases in the Gulf region
- Increased regional instability.
Custody and Nuclear Proliferation Risks
- Damage to nuclear facilities under unstable conditions may lead to loss of control over enriched uranium.
• This raises concerns that nuclear material could fall into the hands of non-state actors.
Relevant Prelims Points:
- International Atomic Energy Agency (IAEA)
- Established in 1957.
- Headquarters: Vienna, Austria.
- Known as the global nuclear watchdog.
- Functions:
- Promote peaceful use of nuclear energy
- Ensure nuclear materials are not diverted to weapons programs
- Conduct safeguards inspections.
- Uranium Enrichment
- Process of increasing the proportion of Uranium-235 isotope in natural uranium.
- Natural uranium contains ~0.7% U-235.
- Low-enriched uranium (LEU): ~3–5% U-235 (used for nuclear power plants).
- Highly enriched uranium (HEU): above 20%, weapons-grade around 90%.
- Caesium-137
- A radioactive isotope produced during nuclear fission.
- Half-life: ~30 years.
- Major source of contamination in nuclear accidents such as Chernobyl and Fukushima.
- Causes long-term soil contamination and radiation exposure.
- Zaporizhzhia Nuclear Power Plant
- Located in Ukraine.
- Europe’s largest nuclear power plant.
- Six reactors with ~6,000 MW capacity.
- Occupied by Russian forces since 2022.
- Geneva Conventions – Additional Protocol I (1977)
- Article 56 protects works containing dangerous forces including:
- Nuclear power plants
- Dams
- Dykes.
- Such installations must not be attacked if civilian harm may result.
Relevant Mains Points:
Targeting nuclear infrastructure in conflicts represents a grave threat to global security and environmental safety.
Major Risks Associated with Attacks on Nuclear Facilities
- Radiological Disaster Risk
- Damage to reactors or fuel pools could trigger large-scale radiation release.
- Comparable disasters include Chernobyl (1986) and Fukushima (2011).
- Global Environmental Impact
- Radiation contamination can affect air, soil, water, and food chains.
- Fallout may spread across borders, impacting multiple countries.
- Weakening of International Humanitarian Law
- Ignoring protections under Geneva Conventions undermines global legal norms.
- Sets dangerous precedents for future conflicts.
- Nuclear Proliferation Risks
- Instability at nuclear facilities increases chances of material diversion.
- Could lead to nuclear terrorism or illegal weapons development.
- Geopolitical Escalation
- Attacks may intensify regional alliances and military escalation.
- Increased tensions between Western powers and emerging blocs (Russia–China–Iran).
- Humanitarian Consequences
- Potential mass refugee flows from affected regions.
- Iran’s population of over 90 million could create large migration crises if instability escalates.
- Way Forward
- Strengthen international legal norms protecting nuclear infrastructure during conflicts.
• Empower IAEA monitoring and enforcement mechanisms.
• Establish demilitarized safety zones around nuclear facilities in conflict zones.
• Promote diplomatic solutions and nuclear non-proliferation agreements.
• Encourage international consensus on prohibiting military attacks on nuclear installations.
