Nuclear Power, Nuclear Energy - Current Affairs Questions and Answers

1)   What is the share of nuclear power in the total electricity generation in the country in 2015-2016?

a. 3.4%
b. 3.5%
c. 3.6%
d. 3.7%
Answer  Explanation 

ANSWER: 3.4%

The share of nuclear power in the total electricity generation in the country was about 3.4% in the year 2015-16.

It will be progressively increased by addition of nuclear power capacity.

The present capacity of 5780 MW will reach 6780 MW by the end of this financial year, with the commercial operation of Kudankulam Unit-2, which is already generating infirm power at the rated capacity.

The capacity is expected to reach 9580 MW by 2020 on progressive completion of projects under construction and about 12980 MW by 2024 on completion of new projects accorded sanction.

A large expansion programme based on both Indian technologies and with foreign technical cooperation is planned ahead.

GoI has also given ‘in principle’ approval for the site at Kovvada in Srikakulam district of Andhra Pradesh.

This is for setting up six Light Water Reactors in cooperation with the USA.

Pre-project activities including land acquisition, obtaining statutory clearances and detailed site investigations are continuing at the site.

In parallel, discussions on the techno-commercial aspects with M/s Westinghouse Electric Company (WEC) to arrive at a project proposal have also started.

2)   Scientists in the US have discovered what material to produce safer economical nuclear reactors?

a. Nanoceramic
b. Nanopolyphenl
c. Nanopolymer
d. None of the above
Answer  Explanation 

ANSWER: Nanoceramic

A team of scientists from the United States have created a Nanoceramic material that can be used to produce safer and economical nuclear reactors.

The team included Fabio Di Fonzo and Kumar Sridharan and others.

The research was published in the Nature journal Scientific Reports in September 2016 with the title “Radiation endurance in Al2O3 nanoceramics.”

Earlier water was used as the primary coolant in reactors for absorbing the heat released from fission reactions which poses risks of corrosion damage to materials.

It also limits the temperatures up to which water-cooled reactors can operate because of which it cannot be used in advanced reactors.

About Nanoceramic material

  • Made of: aluminium oxide nanoceramic coating.
  • Can withstand harsh temperatures and radiation.
  • It becomes tougher under radiation.
  • Can be used in advanced nuclear reactors.
  • Increases energy efficiency, safety and economy.

3)   The largest operating hybrid nuclear desalination plant in the world is located at

a. Mumbai
b. Kudankullam
c. Kalpakkam
d. Chennai
Answer  Explanation 

ANSWER: Kalpakkam

The Nuclear Desalination Demonstration Project (NDDP) at Kalpakkam, Tamil Nadu is the largest operating hybrid nuclear desalination plant in the world.

Desalination of seawater is possible by using Thermal Desalination Technology and/or Membrane Technology like Reverse Osmosis (RO).

Thermal and/or Electrical energy from Atomic Power Station or Nuclear Research Reactor/s can be used for this purpose.

A total of 63 lakh litres per day capacity seawater desalination plant has been setup as Nuclear Desalination Demonstration Project (NDDP) at Kalpakkam, Tamil Nadu and is under regular operation producing 45 lakh litres of water per day by Thermal Desalination process, drawing nuclear low pressure steam from the existing and operating Madras Atomic Power Station (MAPS).

Also, 18 lakh litres of water per day is being produced using membrane based technology using grid electrical energy of MAPS. The sea water desalination plant set up at Kalpakkam is a demonstration plant.

The plant produces dual quality of water – water for high-end industrial applications of quality less than 10 mg per litre of TDS (Total Dissolved Solids) and potable water of less than 500 mg per litre of TDS for drinking and other applications.

4)   With the number of reactors, India ranks how much in the world?

a. 3rd
b. 7th
c. 10th
d. 9th
Answer  Explanation 



  • At present India with twenty one (21) nuclear power reactors, stands seventh (7) among thirty one (31) countries with nuclear power in terms of number of reactors and thirteenth (13) in terms of electricity generation.
  • The present nuclear power installed capacity of 5780 MW is expected to shortly increase to 6780 MW with the start of commercial operation of Kudankulam Unit-2 (KKNPP-2).
  • India has signed nuclear agreements for cooperation in the peaceful uses of nuclear energy with Russia, United States of America (USA), France, Australia, United Kingdom, Czech Republic, Republic of Korea, Kazakhstan, Argentina, Canada, Vietnam and Sri Lanka. India proposes to sign such an agreement with Japan in future.

5)   IGA was signed between Russia and India for setting up nuclear reactors at which location?

a. Kudankulam
b. Kakrapar
c. Both of the above
d. None of the above
Answer  Explanation 

ANSWER: Kudankulam

An Inter-Governmental Agreement (IGA) between Government of India and Government of Russian Federation was signed in December 2008 for setting up units 3 to 6 at Kudankulam, Tamil Nadu in technical cooperation with Russian Federation.

  • Discussions on the draft General Framework Agreement for setting up Units 5&6 (KKNPP 5&6) are currently in progress.
  • The project is planned to be set up on technical cooperation basis with shared scope of work. The Indian private industry would be involved in supply of equipment, execution of the works contracts, providing services in Indian scope of work and localisation of components.

6)   Which nuclear reactor has leaked in the first week of March 2016?

a. Tarapore
b. Kakrapar
c. Kundankalam
d. None of the above
Answer  Explanation 

ANSWER: Kakrapar

There was a leak at the Karapar atomic power station classified as Level 1 or lowest in a 7 rung classification scheme. International Nuclear and Radiological Event scale developed by International Atomic Energy Authority rates the mishap as akin to an anomaly in the plant. In contrast, the Fukushima and Chernobyl leaks were level 7 incidents.

7)   A Chinese nuclear reactor on a machine called EAST has attained three times more heat than the sun. What does EAST stand for?

a. Experimental Advanced Sun Tokamak
b. Experimental Advanced Solar Tokamak
c. Experimental Advanced Superconducting Tokamak
d. None of the above
Answer  Explanation 

ANSWER: Experimental Advanced Superconducting Tokamak

Nuclear reactor in China has created plasma at temperature of 90 million Fahrenheit for 102 seconds (around 49.999 million degrees C or 50 million Kelvins). Temperature is three times hotter than the sun’s core or a mid zed thermo nuclear explosion. This study was conducted at the Institute of Plasma Physics at Chinese Academy of Sciences in Jiangsu province. Research team maintained the high temperature for 1000 seconds or nearly 17 minutes.The EAST machine or Experimental Advanced Supercomputing Tokamak was used for this study. Plasma created is a super hot has formed from the heating of atoms in the magnetic EAST device. EAST experiment follows successful testing of German Wendelstein 7- stellarator fusion reactor earlier in the month for only a second.
