Flora & Fauna

Phytoplankton and Zooplankton
Status: Not Evaluated
Threat: Highly sensitive to thermal shock and chlorination within the cooling water intake and discharge systems of coastal nuclear power plants.
Marine Benthic Communities
Status: Various
Threat: Suffer reduced biodiversity and altered community structures due to elevated temperatures and decreased dissolved oxygen from thermal effluents.
Indian Mackerel (Rastrelliger kanagurta)
Status: Least Concern
Threat: Vulnerable to entrainment in cooling water intake screens and thermal stress from warm water discharge near coastal installations.

Ecology Impact

The expansion of coastal nuclear power plants can lead to thermal pollution, as cooling water discharged back into the sea is typically 7°C to 10°C warmer than ambient temperatures, potentially disrupting local marine ecosystems. Additionally, the construction of large-scale nuclear facilities and associated uranium mining can cause localized habitat fragmentation and soil erosion in ecologically sensitive areas.

Science & Tech Angle

The underlying science involves nuclear fission, where the splitting of heavy nuclei (such as Uranium-235) releases thermal energy to produce steam and drive turbines. Additionally, the integration of trusted Artificial Intelligence (AI) utilizes machine learning algorithms for predictive maintenance, real-time safety monitoring of reactors, and optimizing grid stability for variable power loads.

Climate Change Link

Civil nuclear energy expansion is a key pillar for India to meet its Nationally Determined Contributions (NDCs) under the Paris Agreement, which target achieving 50% non-fossil fuel cumulative electric power installed capacity by 2030. It provides a reliable, low-carbon baseload power source that helps displace coal-fired generation, accelerating India's pathway toward its Net Zero emissions target by 2070.

Sustainable Development

Directly aligns with SDG 7 (Affordable and Clean Energy) by scaling up low-carbon nuclear power, and SDG 13 (Climate Action) by reducing greenhouse gas emissions from the power sector. It also supports SDG 9 (Industry, Innovation, and Infrastructure) through the adoption of trusted AI and advanced nuclear technologies.

International Frameworks

Paris Agreement
Supports India's commitment to transition away from fossil fuels and achieve its Net Zero emissions target by 2070.
Convention on Supplementary Compensation for Nuclear Damage (CSC)
An international treaty signed by India in 2010 and ratified in 2016 to establish a global nuclear liability regime and facilitate international technology transfer.
