Thorium
Syllabus: GS3/ Science and Technology
Context
- Chicago-based Clean Core Thorium Energy (CCTE) has partnered with NTPC Ltd to deploy thorium-based nuclear fuel in India’s existing PHWRs, marking a new phase in India–US civil nuclear cooperation.
About
- CCTE has developed a fuel that blends thorium with HALEU (high-assay low-enriched uranium), enabling its use in India’s existing Pressurised Heavy Water Reactors (PHWRs).
- The fuel, called ANEEL (Advanced Nuclear Energy for Enriched Life), allows large-scale thorium deployment in PHWRs, enhancing energy security, reactor safety, and proliferation resistance
What is Thorium?
- Thorium is a radioactive metallic element found naturally in the Earth’s crust.
- It is fertile, not fissile, meaning it cannot sustain a nuclear chain reaction on its own.
- Thorium Availability in India: Thorium is primarily extracted from monazite sands. India possesses one of the largest thorium reserves globally.
- Major deposits are found in:
- Coastal sands of Kerala, Tamil Nadu, Odisha, Andhra Pradesh, Maharashtra and Gujarat.
- Inland riverine sands of Jharkhand and West Bengal.
Significance of Thorium for India
- Resource Advantage: India has limited uranium but abundant thorium reserves, mainly in coastal and riverine sands.
- Energy Security: Reduces dependence on imported nuclear fuel.
- Nuclear Behaviour: Thorium is not fissile like uranium; it is fertile and converts into uranium-233 after absorbing neutrons, which can then sustain nuclear fission.
- Strategic Fit: Integral to India’s long-term three-stage nuclear power programme.

Secondary Pollutants
Syllabus: GS3/ Environment
In News
- Recent analysis by the Centre for Research on Energy and Clean Air (CREA) shows that secondary pollutants now contribute nearly one-third of Delhi’s annual PM2.5 load.
What are secondary pollutants?
- Secondary pollutants are not emitted directly.
- They are formed in the atmosphere when primary pollutants (gaseous precursors) undergo chemical reactions.
- These reactions depend on sunlight, humidity, temperature, and wind conditions.
- Unlike direct emissions, they accumulate over time and space, often far from the original source, making regulation difficult.
Types
- Inorganic aerosols: Ammonium sulfate (from SO2 + NH3), ammonium nitrate (from NOx + NH3).
- Organic aerosols: Secondary organic aerosols (SOA) from volatile organic compounds (VOCs) oxidation.
- Ground-level ozone: From NOx and VOCs photochemical reactions.

Ancient Marathi literature Reveals Savannas are not Degraded Forests
Syllabus: GS3/Environment
Context
- As per the study of medieval Marathi literature Savannas in western Maharashtra are far older than commonly believed and should not be treated as degraded forests.
Savannas
- A savanna is typically defined as a mixed tree-grass system with scattered trees amidst a continuous layer of grass.
- They are characterized by widely spaced trees, a continuous grass layer, and a distinct wet and dry season.
- It is a type of ecosystem found in tropical regions.
- Unlike dense forests, trees in the savanna are spread out, allowing plenty of sunlight to reach the ground, which supports a wide range of grasses and herbivores.
- Savannas occur where there isn’t enough rain to support a tropical rainforest, but there is enough to keep it from becoming a desert.
- Some examples of savanna habitat are the East African plains, the South American pampas, and the open woodlands of northern Australia.
- Savannas in India: Deccan Plateau: Rain-shadow regions of Maharashtra, Telangana, and Karnataka (Semi-arid).
- Terai Region: The Terai-Duar Savanna and Grasslands at the foothills of the Himalayas are highly productive tall-grass ecosystems (home to the Rhinoceros and Tiger).
- Western India: Parts of Rajasthan and Gujarat (transitioning to Thorn Forests).
