KALPAKKAM NUCLEAR REACTOR – SCIENCE AND TECHNOLOGY

News: Kalpakkam fast breeder reactor nearly complete, says Minister

 

What's in the news?

       The prototype Fast Breeder Reactor (FBR) at the Kalpakkam nuclear power plant in Tamil Nadu is “nearly complete”, Union Minister of State for Atomic Energy Jitendra Singh told the Rajya Sabha.

 

Prototype Fast Breeder Reactor (PFBR):

       PFBR has been designed indigenously by Indira Gandhi Centre for Atomic Research (IGCAR).

       It is a pool-type reactor with 1,750tonnes of sodium as coolant. 

       It is designed to generate 500 MWe of electrical power, with an operational life of 40 years.

       It generates power by burning mixed uranium-plutonium MOX fuel, a mixture of PuO2 and UO2.

       PFBR at Kalpakkam was earlier expected to be commissioned in 2012, but has missed several deadlines.

       PFBR design is built on decades of experience gained from operating a lower power Fast Breeder Test Reactor (FBTR).

       It comes under the second stage of India’s three-stage nuclear power programme.

       Bharatiya Nabhikiya Vidyut Nigam (Bhavini), a public sector company under DAE, has been given the responsibility to build these reactors.

       India is planning to build 21 such reactors by 2030.

 

India's Nuclear Program:

       India's nuclear program can trace its origins to 1944 and its efforts in 3 stage technology were established by Homi Jehangir Bhabha when he founded the nuclear research center, the Tata Institute of Fundamental Research.

       Today, India has 23 nuclear reactors in operation in 7 nuclear power plants, with a total installed capacity of 7,480 MW.

       Kudankulam Nuclear Power Plant is the largest nuclear power station in India, situated in Tamil Nadu.

 

India’s Nuclear Share:

       The present installed nuclear power capacity in the country is 6780 MW.

       The share of nuclear power in the total electricity generation in the country is about 1% in the year 2020-21.

       The present nuclear power capacity of 6780 MW is planned to be increased to 22480 MW by 2031 on progressive completion of projects.

 

Importance of Nuclear Energy:

1. Thorium and Uranium reserves:

       India has vast reserves of Thorium that can fuel India’s nuclear energy provided appropriate technology. India’s thorium deposits, estimated at 3,60,000tonnes, and natural uranium deposits at 70,000tonnes.

       The country’s thorium reserves make up 25% of the global reserves.

2. Energy poverty:

       Although India is the 3rd largest producer of electricity, about 20 % of the population of the country does not have access to electricity today.

       The per capita consumption of electricity is very low at about 1,181 kWh per annum, about half of the world average and way below that of advanced countries.

       There exist shortages in energy and peak power in the range 10-15%.

3. Energy demand:

       Nuclear energy is a critical part for India’s future energy security.

       As we know India’s annual energy demand is expected to rise to 800 GW by 2032, it is very important to consider every source of energy in the optimum energy mix.

4. Energy efficiency:

       Quantities of nuclear fuel needed are considerably less than thermal power plants.

       For instance, 10000 MW generation by coal will need 30-35 million tons of coal, but nuclear fuel needed will be only 300-350 tons.

5. Economic growth:

       Rapid economic growth is also critical to achieve developmental objectives and poverty alleviation.

       A sustained economic growth of about 8 to 10% is needed over the next few decades.

       As electricity is a key driver for economic growth, it is necessary that there is a massive augmentation in electricity capacity, apart from transmissions and distribution systems.

6. Decrease in Energy Supply:

       Energy supply has been negatively affected by changing weather patterns.

       As water reservoirs decrease due to lower precipitation and increased evaporation, capacity for electricity production from hydropower and other water-intensive generation technologies may decline.

7. Climate change:

       Due to its emission-free nature, nuclear energy can contribute to global efforts under the Paris Agreement.

       India’s Nationally Determined Contribution (NDC) to the United Nations Framework Convention on Climate Change (UNFCCC) has outlined goals to reduce the carbon emissions intensity of its economy by 45% by 2030 as well as increase the clean energy electricity capacity to 50% of the total installed capacity in the same period.

 

Challenges:

1. Public Awareness:

       Commercial nuclear power is sometimes viewed by the general public as a dangerous or unstable process.

       This perception is often based on three global nuclear accidents, its false association with nuclear weapons.

2. Used Fuel Transportation, Storage and Disposal:

       Many people view used fuel as a growing problem and are apprehensive about its transportation, storage, and disposal.

3. Constructing New Power Plants:

       Building a nuclear power plant can be discouraging for stakeholders.

       Conventional reactor designs are considered multi-billion dollar infrastructure projects.

       High capital costs, licensing and regulation approvals, coupled with long lead times and construction delays, have also deterred public interest.

4. High Operating Costs:

       Challenging market conditions have left the nuclear industry struggling to compete. Strict regulations on maintenance, staffing levels, operator training, and plant inspections have become a financial burden for the industry.
