Introduction

In 1934, an Italian scientist named Fermi and his colleagues bombarded uranium with slow moving neutrons and he realized that it produced much higher radioactivity than any other element treated the same way. Five years later Fermi discovered that the nucleus of uranium 235, if hit by a neutron, would split down the middle in two very similar fragments. This process was to be known as nuclear fission and it resulted in strong energy emission at the expense of the nucleus’ initial mass. The use of nuclear fission for civilian uses bases itself on the ability of controlling the chain reaction of such a process. In nuclear plants, the process of fission is tightly controlled through the use of special materials such as cadmium that are able to absorb neutrons and regulate the heat produced. India has a streamlined nuclear power program and expects to have 20,000 MWe nuclear capacities on line by 2020. It aims to supply 25% of electricity from nuclear power by 2050. Since India is outside the Nuclear Non-Proliferation Treaty due to its weapons program, it had been largely excluded for 34 years from trade in nuclear plant or materials, which has hindered its development of civil nuclear energy until 2009. After the NSG approval the problems have been rectified. India’s vision is to become a world leader in nuclear technology due to its expertise in fast reactors and thorium fuel cycle.

Nuclear Power: The Present Status

Potential

Uranium reserves in India pertaining to categories RAR, EAR-I and EAR-II are estimated to be about 95,000 tonnes of metal. Speculative reserves are over and above this quantity and with further exploration, could become available for nuclear power programme. After accounting for various losses including mining (15%), milling (20%) and fabrication (5%), the net uranium available for power generation is about 61,000 tonnes. Thorium reserves are present in a much larger quantity. Total estimated reserves of monazite in India are about 8 million tonnes (containing about 0.63 million tonnes of thorium metal) occurring in beach and river sands in association with other heavy minerals. Out of nearly 100 deposits of the heavy minerals, at present only 17 deposits containing about ~4 million tonnes of monazite have been identified as exploitable. Mineable reserves are ~70% of identified exploitable resources. Therefore, about 2,25,000 tonnes of thorium metal is available for nuclear power programme.[iii] 

The known reserves of uranium in the country can support about 10 GWe of installed electricity capacity based on PHWRs for a life-time of 40 years at 80% capacity factor.[iv]

India Nuclear Roadmap

Department of Atomic Energy is carrying out nuclear energy programme in India. The Indian Nuclear Power Programme has the following three stages. 

The Indian Nuclear Power Programme has the following three stages.

 1.First Stage: It is already commercial now, comprised setting up of PHWRs (pressurized heavy water reactors) and associated fuel cycle facilities. PHWRs use natural uranium as fuel and heavy water as moderator and coolant. The design, construction, and the operation of these reactors are undertaken by public sector undertaking the NPCIL (Nuclear Power Corporation of India Limited). The company operates 16 reactors (2 Boiling Water Reactors and 14 PHWRs) with a total capacity of 3900 MWe.

  2.Second Stage: It was envisaged to set FBRs (Fast Breeder Reactors) along with Reprocessing plants and plutonium-based fuel fabrication plants. Plutonium is produced by irradiation of Uranium-238. The Fast Breeder Programme is in the technology demonstration stage. Under this stage, the IGCAR (Indira Gandhi Center for Atomic Research) has completed design of a 500 MWe PFBR (prototype fast breeder reactor) being implemented by BHAVINI (Bharatiya Nabhikiya Vidyut Nigam).

  3.Third Stage: The Indian Nuclear Power Programme is based on the thorium-uranium-233 cycle.Uranium-233 is obtained by irradiation of thorium. Presently this stage is in technology development phase. The ongoing development of 300 MWe AHWR (advanced heavy water reactor) at BARC (Bhabha Atomic Research Centre) concerns thorium utilization and its demonstration.

Barriers

  • High initial construction costs
  • High operating and maintenance costs
  • Mining and purifying uranium is not a very clean process
  • Improperly functioning nuclear plants can lead to devastating disasters (eg. meltdowns)
  • Spent fuel from nuclear power plants is toxic for centuries and there is no safe/permanent storage area for it

Nuclear energy companies  

Bharat electronics limited (BEL)

Expecting the nuclear deal with US to go through, India's largest defence electronic company Bharat Electronic Ltd (BEL) is looking at tapping the lucrative business potential in the atomic energy sector. explained.
