India's three-stage nuclear power programmeIndia's three-stage nuclear power programme was formulated by Homi Bhabha, the well-known physicist, in the 1950s to secure the country's long term energy independence, through the use of uranium and thorium reserves found in the monazite sands of coastal regions of South India. The ultimate focus of the programme is on enabling the thorium reserves of India to be utilised in meeting the country's energy requirements.
Thorium-based nuclear powerThorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium. A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle—including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced nuclear waste production. One advantage of thorium fuel is its low weaponization potential; it is difficult to weaponize the uranium-233/232 and plutonium-238 isotopes that are largely consumed in thorium reactors.
Nuclear power in IndiaNuclear power is the fifth-largest source of electricity in India after coal, gas, hydroelectricity and wind power. , India has 22 nuclear reactors in operation in 8 nuclear power plants, with a total installed capacity of 7,380 MW. Nuclear power produced a total of 43 TWh in 2020–21, contributing 3.11% of total power generation in India (1,382 TWh). 10 more reactors are under construction with a combined generation capacity of 8,000 MW. In October 2010, India drew up a plan to reach a nuclear power capacity of 63 GW in 2032.
Cycle du combustible nucléaire au thoriumLe cycle du combustible au thorium décrit l'utilisation du thorium 232, un élément abondant dans la nature, comme matériau fertile permettant d'alimenter un réacteur nucléaire. Le cycle du thorium présente de nombreux avantages théoriques par rapport à un cycle à l'uranium : le thorium est trois à quatre fois plus abondant que l'uranium, notamment dans les pays qui sont susceptibles de construire des réacteurs dans le futur, comme l'Inde, le Brésil et la Turquie.
Generation IV reactorGeneration IV reactors (Gen IV) are nuclear reactor design technologies that are envisioned as successors of generation III reactors. The Generation IV International Forum (GIF) - an international organization that coordinates the development of generation IV reactors - specifically selected six reactor technologies as candidates for generation IV reactors. The designs target improved safety, sustainability, efficiency, and cost.
