NUCLEAR POWER PLANTS IN THE WORLD

There are 439 nuclear power reactors operating in 31 countries

• Around 13% of the world's electricity is produced from nuclear energy, more than from all sources worldwide in 1960.

• Today, reactors derived from designs originally developed for propelling submarines and large naval ships generate about 85% of the world's nuclear electricity

Nuclear Power Plants in India

• India has 20 nuclear reactors in operation in six nuclear power plants, generating 4,780 MW

• India drew up "an ambitious plan to reach a nuclear power capacity of 63,000 MW in 2032"
