• Nuclear power contributes a little over 1.8% of our total energy generated at present.

• The United States is the largest producer of nuclear power, while France has the largest share of electricity generated by nuclear power. 

Top 5 countries by Nuclear power production
1. United States – (Number of Reactors 96)
2. France – (Number of Reactors 58)

Bhabha Atomic Research Centre (BARC)

•  In India the nuclear power program was initiated in the year 1940, after the  incorporation of the Tata Atomic Research Commission in August 1948.

• Although the real progress was made only after the establishment of the Atomic Energy Institution at Trombay in 1954.

• In the year 1967 the Atomic Energy Institution at Trombay renamed as the ‘Bhabha Atomic Research Centre (BARC)’.

• The first nuclear power station with 320 MW capacity was set up at Tarapur near Mumbai in 1969.

• Headquarter of BARC is located in Trombay, Mumbai, Maharashtra.
• BARC was Founded by the Indian nuclear physicist Homi Jehangir Bhabha.
• He is the “Father of the Indian nuclear programme”.
• Bhabha was awarded the Adams Prize (1942) and Padma Bhushan (1954).

• Bhabha Atomic Research Centre operates under the Department of Atomic Energy(DAE).

• BARC conducts extensive and advanced research and development covering the entire spectrum of electronics, instrumentation, chemical engineering, biology and medicine, nuclear science, material sciences and metallurgy,   advance computing, high-energy plasma physics and associated research for Indian nuclear program and related areas.

Three-stage nuclear power programme of India

Why we need the three-stage nuclear power programme

• Most of the nuclear reactor in the world used uranium-233, uranium-235 and plutonium-239 as a fuel or fissile material.

• But India has only 1-2% of the global Uranium reserves.

• But the good news is India has 25% of the Thorium (Th-232) reserves.
• Here the problem is we cannot use Thorium as a fissile material. Because Th-232 is not an ideal feul for producing nuclear power.

• To use these Thorium-232 it must be transmuted to Uranium-233 in a reactor fueled by other fissile materials(Pu-239 or U-235)

• Hence a three stage nuclear program was designed to finally use the vast resources of Thorium in the third stage.

Initiation of the Three-stage nuclear power programme in India

• India’s three-stage nuclear power programme was formulated by Homi Bhabha and Jawaharlal Nehru in the 1950s.

• The ultimate focus of the 3-stage programme is the optimum use of the vast thorium reserve of India to fulfil the country’s energy requirements.

• The three stages are:-
1. Stage I – Pressurised Heavy Water Reactor (PHWR)
2. Stage II – Fast Breeder Reactor (FBR)
3. Stage III – Advanced Heavy Water Reactor (AHWR)

Details about the Three-stage nuclear power programme of India

Stage I – Pressurised Heavy Water Reactor (PHWR)

• Fuel or Input material :- Natural Uranium (U-238)
• Moderator used :- Heavy water
• Byproduct of stage I – Plutonium – 239

• Natural uranium contains only 0.7% of the fissile isotope uranium-235.
• Most of the remaining 99.3% is uranium-238 which is not fissile, but can be converted in a reactor to the fissile isotope plutonium-239.
• Heavy water (deuterium oxide, D2O) is used as moderator and coolant.
• Instead of using PHWR we can also use the Light Water Reactor (LWR) but the LWR needed enriched uranium.

• And in case of India it would be easier to create heavy water production facilities (which required for PHWRs) than uranium enrichment facilities (required for LWRs).

• The byproduct of stage-I (Pu-239) would be used in later stages.

Stage II – Fast Breeder Reactor (FBR)

• Fuel or Input material – Plutonium-239 (byproduct of stage-I)
• Moderator used – Not required
• Byproduct of stage II – mixed oxide (MOX) fuel. [Plutonium – 239 and uranium-238]

• In this stage the fuel, plutonium-239 undergoes fission to produce energy.
• While the uranium-238 present in the mixed oxide fuel transmutes to additional plutonium-239.

• Thus, the Stage II produced more Pu-239 than it consumes. Hence, it is called a breeder reactor.

• The design of the country’s first fast breeder, called Prototype Fast Breeder Reactor (PFBR).

• The Prototype of Fast Breeder Reactor was developed by the Indira Gandhi Centre for Atomic Research (IGCAR).

• Bharatiya Nabhikiya Vidyut Nigam Ltd (Bhavini), a public sector company under the
Department of Atomic Energy (DAE), has been given the responsibility to build the fast breeder reactors in India.
• The construction of this PFBR was started at Kalpakkam, Tamil Nadu.

• After sufficient stock of Pu-239 is made, Thorium will be used to produce U-233 which will be used in the third stage.

Stage III – Advanced Heavy Water Reactor (AHWR)

• The main purpose of stage III is to achieve a sustainable nuclear fuel cycle.
• Fuel – U-233 and Thorium – 232
• This stage, also known as Thorium based reactors, as it used natural thorium as a fuel.

Thorium deposits of India

• Thorium is a chemical element with symbol Th and atomic number 90.
• Thorium is found in small amounts in most rocks and soils.
• Soil typically contains an average of round 6 parts per million (ppm) of thorium.

•  Most common minerals of Thorium _

  1. Thorite (ThSiO4)
  2. Thorianite (ThO2 + UO2)
  3. Monazite

• Thorianite is a rare mineral and may contain up to about 12% thorium oxide.

• Monazite contains 2.5% thorium.
• The Monazite sand is widely scattered on the Coast of Kerala.

• Thorium concentrations near the surface of the earth can be mapped using gamma spectroscopy.

• In India thorium is mostly located in a contiguous belt of eastern coastal states.

• India’s thorium deposits, estimated at 360,000 tonnes.
• India’s thorium reserves make up 25 per cent of the global reserves.
• United States, Australia, and India have particularly large reserves of thorium.
