India has the world's largest deposits of Thorium

Nuclear Program using Thorium is legendary.

India has the world's largest deposits of Thorium. Thorium is a naturally occurring radioactive chemical element that can replace Uranium for nuclear fuel. India's Nuclear program also consists of using Thorium (232) instead of Uranium (Uranium 238). 

 

Here is a comparison:

Thorium is also safer, is much more abundant and has greater potential of generating energy.

Here is an example:

This is the reserve in tonnes according to IAEA
India         519,000 21%
Australia   489,000 19%
USA         400,000 13%
Turkey      344,000 11%
Venezuela 302,000 10%
Brazil        302,000 10%
Norway     132,000  4%
Egypt       100,000  3%
Russia       75,000  2%
Greenland  54,000  2%
Canada      44,000  2%
South Africa18,000 1%
"Other countries" 33,000 2%
"World total" 2,810,000

Distribution of thorium in India

India's Nuclear Program is the best known nuclear programme using Thorium.
Even most of the research on Nuclear Programs using thorium is done by India.
